2016 in aviation

Events

January

• During the month, the Government of Italy gives permission for armed U.S. unmanned aerial vehicles to fly strike missions from Naval Air Station Sigonella on Sicily – where the United States has based unarmed surveillance UAVs since 2001 – against Islamic State targets in Libya, but only if they are "defensive," meaning that they are flown to protect U.S. special operations forces operating in and near Libya or rescuers attempting to retrieve downed U.S. pilots. Italy continues to prohibit U.S. offensive strikes from Italian territory, and also reserves to itself the right to veto any U.S. mission.

• Indian aerial surveillance platforms detect a group of gunmen entering an Indian Air Force base at Pathankot, India, and Indian Air Force security forces exchange fire with them in a housing area. Four of the gunmen and two Indian Air Force security personnel are killed. Gunfire erupts again two hours later, and Indian helicopters fire on gunmen in the base later in the day. Indian security forces finally declare the base secure in the late afternoon, 14 hours after the intrusion began.

• Combat again breaks out at India's air base at Pathankot after security forces discover two militants still hiding on the base. Security forces reportedly kill the militants.
• An official at the United States Embassy in Addis Ababa announces that by mutual agreement with the Government of Ethiopia the United States had shut down its military unmanned aerial vehicle base at Arba Minch Airport in Arba Minch in southern Ethiopia in September 2015. The two countries had agreed that the base, which had opened in 2011, was no longer necessary. It is the first public announcement that the base had been closed.

• Saudi Arabia's civil aviation authority suspends all civilian flights between Saudi Arabia and Iran. The move, which comes a day after Saudi Arabia severed diplomatic relations with Iran, raises doubts about the future ability of Islamic pilgrims from Iran to visit Mecca and of Shiite pilgrims from Saudi Arabia to visit religious sites in Iran.
• John Boggs files suit against William Merideth for shooting down his unmanned aerial vehicle in Bullitt County, Kentucky, with a shotgun as the UAV hovered over Merideth's property, asserting that the drone was in public airspace when it was shot down and requesting $1,800 in damages and clarification as to how high above private property public airspace begins. Merideth had claimed the UAV was spying on his family and violating his privacy. The case promises to spur the U.S. judicial system to clarify where private property rights end and federal jurisdiction begins in U.S. airspace, with a significant potential impact on future private and commercial UAV operations.

• When two United States Air Force Sikorsky HH-60 Pave Hawk helicopters attempt to evacuate wounded Afghan military personnel near Marjah, Afghanistan, one strikes a wall and is disabled and the other is ordered to abort the mission under heavy ground fire. One American is killed and two wounded in the incident; they are the first U.S. casualties in Afghanistan in 2016.

• Iran claims that an airstrike by the Saudi-led coalition operating against rebel forces in Yemen struck its embassy in Sana'a overnight. Local residents and press observers report no signs of damage at the embassy.
• A report by the inspector general of the United States Department of Transportation to the U.S. Federal Aviation Administration expresses a concern that airline pilots have become so reliant on automation technology to fly their aircraft that they have lost the skills necessary to take manual control of an airliner in order to deal promptly and effectively with unforeseen events. The FAA responds that it will require enhancements in pilot training for the manual flight of aircraft, and the Air Line Pilots Association endorses the need for well-trained aircrew aboard airliners.

• West Air Sweden Flight 294, a Canadair CL-600-2B19 Regional Jet CRJ-200PF on a domestic cargo flight in Norway carrying mail and packages from Oslo to Tromsø, suddenly goes into a steep descent after a brief Mayday call and crashes near Akkajaure, Sweden, killing its crew of two.

• Tracey Curtis-Taylor completes a solo flight from Farnborough Airport in Farnborough, England, to Sydney, Australia, in the Boeing-Stearman Model 75 open-cockpit biplane Spirit of Artemis. During the 100-day, flight, begun on 1 October 2015, she has flown over 23 countries and made 50 refueling stops. The flight recreates the 1930 Croydon-to-Darwin flight of Amy Johnson, the first solo flight between the United Kingdom and Australia by a woman.

• As a show of force after a 6 January nuclear weapons test by North Korea, a Guam-based U.S. Air Force B-52H Stratofortress flies to South Korea, where it circles over Osan Air Base flanked by a U.S. Air Force F-16 Fighting Falcon and a Republic of Korea Air Force F-15 Eagle before returning to Guam.

• An unarmed Iranian unmanned aerial vehicle flies near the French Navy aircraft carrier Charles de Gaulle and directly over the United States Navy aircraft carrier as they operate in international waters in the Persian Gulf. Iran will announce the flight and release purported video from it on 29 January – implying that the video had been taken earlier that day rather than on 12 January – and a United States Fifth Fleet spokesman will respond by calling the flight "abnormal and unprofessional."
• An air-and-bus bridge begins operating as a pilot program to help 8,000 Cuban immigrants stranded in Costa Rica since Nicaragua closed its border to them on 13 November 2015 by allowing them to fly out of Costa Rica and reach Mexico, from which they can emigrate to the United States. The first flight of the air-and-bus bridge departs Liberia, Costa Rica, during the evening as part of regional agreement to help the Cubans bypass Nicaragua.

• An Israeli Air Force aircraft strikes a group of Palestinians – members of the Al-Aqsa Martyrs Brigade – on a beach in the northern Gaza Strip near the Israeli border fence, killing one and injuring three others. The Israel Defense Force claims that they were planting explosives with which to target Israeli soldiers patrolling the border on the other side of the fence.

• Air France officially retires the Boeing 747 from its fleet with Flight 744, a scenic flight by a Boeing 747-400 with 432 people on board, including 380 paying passengers, in formation with 12 Dassault/Dornier Alpha Jets of the French Air Force's Patrouille de France aerobatic team. The airliner takes off from Charles de Gaulle Airport in Paris and makes a clockwise circuit that takes it over Lyon, Geneva, Marseille, Montpellier, Bordeaux, and Deauville before returning to Charles de Gaulle Airport, offering passengers scenic views of Mont Blanc, Normandy, and Mont Saint-Michel along the way. The Boeing 747 had been part of the Air France fleet since 1974 and the 68 Boeing 747s the airline had operated had carried 250 million passengers. In the future plans to use its Airbus A380s and Boeing 777s for long-haul flights.
• Two United States Marine Corps Sikorsky CH-53 Sea Stallion helicopters of Marine Heavy Helicopter Squadron 463, each carrying six Marines, collide and crash in a fireball late in the evening over the Pacific Ocean north of Oahu just off Haleiwa, Hawaii, and crash, leaving all 12 Marines missing.

• SpaceX successfully fires the engines of the first stage of Falcon 9 rocket it had used to launch a satellite into orbit and then landed successfully on land in December 2015, the first time in a history a rocket stage had made a soft, controlled landing. The firing of the engines demonstrates the feasibility of reusing the rocket stage, an important step in the development of reusable rockets that make space launches less expensive.

• Speaking at the conclusion of a missile exercise at Skwierzyna, Poland, involving U.S. and Polish military forces, Polish Minister of National Defense Antoni Macierewicz says that the Government of Poland wants a permanent presence of North Atlantic Treaty Organization and U.S. military forces in Poland, including MIM-104 Patriot surface-to-air missiles.

• After successfully launching the Jason-3 satellite into orbit from Vandenberg Air Force Base in California, the first stage of a SpaceX Falcon 9 rocket touches down on a landing platform in the Pacific Ocean off California softly enough to land successfully, but topples over when of its landing legs fails to lock in place and collapses. It is SpaceX's third attempt to land a Falcon 9 first stage at sea; the two previous attempts, both in 2015, also had been unsuccessful, although SpaceX had made history's first successful landing of a reusable rocket stage – also of a Falcon 9 – on land in December 2015.
• Just before midnight, aircraft of the Saudi-led coalition strike a police facility in Sana'a, Yemen, used by both security forces and the Houthi rebels as an assembly point, killing 26 people and injuring 15. The dead and wounded are all policemen and Houthi rebels.

• The United States Fish and Wildlife Service announces that after the 2016 season it will end its support of the use of ultralight aircraft to lead whooping cranes on their migration from Wisconsin to the Florida Gulf Coast each autumn in Operation Migration. A conclusion by experts in whooping crane biology that human intervention such as ultralight flights impairs the ability of the cranes to learn the parenting skills necessary to raise chicks in the wild prompts the decision to end support.

• The United States Department of the Treasury announces the lifting of major U.S. trade and travel restrictions on Cuba. The new regulations allow code sharing between U.S. and Cuban airlines, airplane-leasing deals in the United States for Cuba, and permission for U.S. airline crews to travel to Cuba.

• Iran agrees to buy 118 airliners – 73 wide-body and 45 narrow-body – from Airbus in a deal worth $27,000,000,000. The purchase consists of 12 A380, 16 A350-1000, 45 A330, and 45 A320-family aircraft. The deal is contingent on Airbus receiving export licenses from the United States, where 10 percent of parts for Airbus aircraft are manufactured.

• United States Secretary of State John Kerry meets in Moscow with President of Russia Vladimir Putin to discuss a U.S. proposal supported by senior United Nations officials to "integrate" U.S. and Russian air operations against Islamic State and Jabhat al-Nusra targets in Syria and halt Syrian government and Russian air attacks against civilians and moderate Syrian rebel forces that are parties to a widely violated February 2016 ceasefire agreement. The proposal calls for Russia to pressure the Syrian government to ground all Syrian military aircraft and restrict Russian airstrikes to Islamic State and Jabhat al-Nusra targets, and for U.S. airstrikes against Jabhat al-Nusra – previously conducted only rarely to avoid direct U.S. involvement in the Syrian Civil War – to expand alongside strikes against Islamic State targets in Syria. Under the proposal, Russia and the United States – via a Joint Implementation Group headquartered in Amman, Jordan – would share intelligence and strike planning for Jabhat al-Nusra leadership targets, headquarters, training camps, logistical depots, and supply lines, with other areas off-limits to airstrikes by either country, and a "liaison body" would ensure that Russia and the United States inform one another at least a day in advance of planned strikes against agreed-upon targets. The proposal calls for implementation of an agreement by 31 July. The following day, Kerry and Foreign Minister of Russia Sergei Lavrov announce after day-long talks that the two countries have reached an agreement that could reduce civilian casualties and improve targeting of terrorist groups, but they reveal no details to the public.
• Airbus and Boeing experience their lowest airliner sales totals at the Farnborough Air Show in six years, securing deals for about 400 aircraft worth about $50,000,000,000, only half their sales at the previous year's show.

• According to the International Air Transport Association, commercial air traffic to and from Venezuela has dropped 30 by percent since the Venezuelan bolívar began a steep decline in value in 2013 despite a rapid increase in air travel almost everywhere else in the world. International air carriers have accumulated about $4,000,000,000 in almost worthless bolívars which the Government of Venezuela prohibits them from converting into hard currency, prompting various airlines since 2014 – including Aeroméxico, Air Canada, Alitalia, LATAM, and Lufthansa – to cease service to Venezuela and others to reduce flights or provide service with smaller planes; only Venezuelan airlines are permitted to pay for fuel with bolívars, all other carriers being required to pay in United States dollars. Simón Bolívar International Airport in Caracas, long a major hub for airlines serving South America, has been replaced in that role by airports such as El Dorado International Airport in Bogotá, Colombia, which now handles three times as many passengers as Caracas, and Jorge Chávez International Airport in Callao, Peru, which has enjoyed a 35 percent increase in passengers over the previous two years. Caracas has become so dangerous that Copa Airlines crews are prohibited from leaving their hotel rooms when staying there, massive shipments of cocaine originating in Caracas have been interdicted in the airport's terminal, and gunfights between police and criminals occur every few months in the airport's parking lots.

• During the month, Delta Air Lines sends a letter of protest to the U.S. General Services Administration, complaining that GSA's award to JetBlue Airways of the U.S. government contract routes from New York City to Dubai and from New York City to Milan, Italy, in 2015 violates the 1981 Fly America Act – which requires U.S. federal government employees, their families, and federal consultants and contractors to travel aboard U.S. carriers when on official business paid for by the U.S. government – because JetBlue has no aircraft that can fly that far and will book its passengers to those destination on its codeshare partner Emirates, a United Arab Emirates airline based in Dubai. Delta joins American Airlines and United Airlines in arguing that they should be selected for such routes to reduce the disadvantage they face when competing with Emirates, the UAE's Abu Dhabi-based Etihad Airways, and Qatar's Qatar Airways, all of which receive substantial subsidies from their governments. The GSA responds that JetBlue offers cheaper prices that Delta, American, and United and that its selection does not violate the Fly America Act, regardless of its use of foreign codeshare partners for the routes.

• Believing that they are attacking Islamic State forces, aircraft of the U.S.-led coalition – which the Syrian government claims are two F-16 Fighting Falcons and two A-10 Thunderbolt IIs flying into Syria from Iraq – mistakenly strike Syrian Arab Army forces in Syria's Deir ez-Zor Governorate. The strike destroys approximately six ground vehicles according to a United States Central Command estimate before Russia alerts Central Command that the strike is targeting Syrian Arab Army forces; the aircraft then cease fire and the United States express regret over the strike. Russia and Syria claim that the targeted forces were fighting against the Islamic State and that the strike killed 62 Syrian soldiers and wounded 100. It is the first combat engagement between the U.S.-led coalition and Syrian forces since the coalition began air raids in Syria in 2014. Arguing that the strike is a ceasefire violation that may be evidence of U.S. military support for the Islamic State in the Syrian Civil War, Russia calls an emergency Saturday-evening meeting of the United Nations Security Council to discuss the incident.

At the U.N. Security Council, U.S. Secretary of State John F. Kerry accuses Moscow of inventing its "own facts" to explain the air attack, which the United States had blamed on the Russian Federation Air Force, adding that "We don’t get anywhere by ignoring facts and denying common sense;" he calls for Russia and Syria to "immediately ground all aircraft" flying in areas of northwest Syria where the convoy was hit.
• The United States Department of the Treasury's Office of Foreign Assets Control grants Airbus and Boeing licenses to sell airliners to Iran. Airbus's license covers the first 17 A320s and A330s that Iran agreed to purchase in a January; although based aboard, the company required U.S. Government permission because at least 10 percent of the airliners' components are manufactured in the United States. Boeing's license allows it to sell 80 airliners and lease another 29 new Boeing 737s to Iran.

• Throughout the day, suspected Syrian Arab Air Force and Russian Federation Air Force aircraft strike targets in rebel-held areas of Aleppo, Syria; twenty-one people die in evening air raids on two Aleppo neighborhoods, and scores have died in airstrikes in the city since 19 September. At the U.N. Security Council, U.S. Secretary of State John F. Kerry repeats his 21 September call for Syria and Russia to ground their aircraft in northeastern Syria, saying that "the only way" for the Syrian ceasefire to succeed is "if the ones who have the air power in this part of the conflict simply stop using it... . Absent a major gesture like this, we don’t believe there is a point in making more promises, issuing more plans." The U.S. Chairman of the Joint Chiefs of Staff, United States Marine Corps General Joseph Dunford, tells the United States Senate Committee on Armed Services that "I would not agree that coalition aircraft ought to be grounded...I do agree that Syrian regime aircraft and Russian aircraft should be grounded...There's no reason to ground our aircraft...We’re not barrel-bombing civilians; we’re not causing collateral damage."
• The World Trade Organization rules that the European Union, France, Germany, Spain, and the United Kingdom have failed to halt illegal subsidies to Airbus that the WTO had ordered them to stop in 2011 despite reporting in late 2011 that they had done so. The WTO adds that the subsidies – which total $22,000,000,000 over ten years – have cost the economy of the United States tens of billions of dollars and cost Boeing nearly 400 potential airliner sales in 2012 and 2013 alone. The ruling is a sweeping victory for the United States and its aerospace industry, which has disputed European aircraft subsidies for 40 years and first filed a complaint with the WTO about Airbus subsidies in 2004.

• Intense Russian and Syrian airstrikes in and around rebel-held areas of Aleppo, Syria, kill at least 85 people, with observers claiming that attacking aircraft are employing white phosphorus munitions, cluster munitions, and incendiary and "bunker buster" bombs. Since 19 September, the strikes have destroyed so many ambulances that humanitarian aid workers and first responders have great difficulty responding to reports of casualties. At the U.N. Security Council, United States Ambassador to the United Nations Samantha Power accuses Russia of "barbarism" and claims the strikes are a war crime, while the Permanent Representative of Russia to the United Nations, Vitaly Churkin, responds that the collapse of the ceasefire is due to transgressions by U.S.-backed rebel forces.

• The U.S. Federal Aviation Administration demonstrates its Next Generation Data Communications system – a component of its Next Generation Air Transportation System – to the media at Washington Dulles International Airport in Virginia. The system, already installed at air traffic control towers at 45 airports in the United States, is intended to replace the existing archaic U.S. system of communications between airline pilots and control towers – which requires printing out flight plans in towers, discussion by radio between towers and pilots, and pilots writing down flight plans by hand in the cockpit – with all-digital communications, allowing improved speed and efficiency. The FAA plans to install the system at 50 more U.S. airports before the end of 2016, and then to install it at en route air traffic control centers across the United States, with a goal of achieving voiceless, in-flight communications between air traffic controllers and airliner pilots throughout the country by mid-2019. The FAA estimates that the new system will save air carriers $10,000,000,000 over the next 30 years.

The announcement states that in a telephone conversation earlier in the day with Russian Minister of Foreign Affairs Sergey Lavrov, U.S. Secretary of State John F. Kerry "made clear that the United States and its partners hold Russia responsible for the situation, including the use of incendiary and 'bunker buster' bombs in an urban environment, a drastic escalation that puts civilians at great risk" and "informed that the United States is making preparations to suspend U.S.-Russia bilateral engagement on Syria – including on the establishment of a Joint Implementation Center to coordinate strikes on terrorist targets – unless Russia takes immediate steps to end the assault on Aleppo and restore the cessation of hostilities."
• A Dutch team investigating the crash of Malaysian Airlines Flight 17 in Ukraine in July 2014 announces that it has concluded that the airliner was shot down by a surface-to-air missile fired by a Russian-made Buk missile system smuggled from Russia into an area of eastern Ukraine held by pro-Russian separatists a few hours before it fired at the airliner and returned to Russian territory the following day. The Dutch team says that it has identified over 100 people linked to the firing of the missile and that it will continue its investigation – extended into at least 2018 – –in order to determine who ordered it fired. The U.S. Department of State notes that the Dutch team's findings match those of American investigators, while the Russian ministries of defense and foreign affairs dismiss some of the Dutch team's evidence and declare its investigation biased and Russian separatists in Ukraine claim they have no access to sophisticated surface-to-air missiles and blame the airliner's destruction on the Ukrainian armed forces.

• Russia responds to U.S. criticism of its air campaign in eastern Aleppo, Syria, by saying that the airstrikes are justified because the United States violated the ceasefire agreement of 12 September by failing to fulfill its promise to separate al-Qaeda- and Islamic State-linked forces from other rebel forces and because the ceasefire agreement had become unacceptable because it a;;owed "terrorist groups to take necessary measures to replenish supplies regroup forces."

• Russian and Syrian aircraft conduct heavy airstrikes against rebel-held residential areas in eastern Aleppo, Syria, including the use of white phosphorus and cluster munitions; two more hospitals are among the targets hit during the day.
