This is a list of aviation-related events from 1931:

Events

Bert Hinkler flies a de Havilland Puss Moth from Canada to New York City, then non-stop 2,400 km (1,500 mi) to Jamaica, then on to British Guiana and Brazil. He then flies across the South Atlantic Ocean to West Africa in extremely bad weather, becoming the first person to fly across the South Atlantic solo and only the second person after Charles Lindbergh in 1927 to fly solo across the Atlantic. He completes his journey by flying from West Africa to London.^[1] For the flight, he receives the Segrave Trophy, the Johnston Memorial Prize, and the Britannia Trophy for the most meritorious flying performance of the year.
Manufacturer Airspeed Ltd founded in York, England.
Alexander Seversky founds the Seversky Aircraft Corporation.^[2]
Watanabe Iron Works, the ancestor of the Kyūshū Airplane Company Ltd., begins to manufacture aircraft.^[3]
Franco-British Aviation (FBA) ceases aircraft design and development, the victim of a lack of civilian orders for its aircraft since the end of World War I. The company had been founded in 1913.^[4]
The first Bendix trophy race takes place.
The Imperial Japanese Navy decides to abolish its airship units and phase airships out of the fleet over the next few years.^[5]
In New York City, the Empire State Building is completed, topped with a 200-foot (61-meter) mooring mast for airships. Plans to disembark airship passengers prove impractical, and the mast is never used except for a single three-minute contact by the United States Navy blimp J-4.^[6]
Spring 1931 – At the Langley Memorial Aeronautical Laboratory at Langley Field in Hampton, Virginia, the National Advisory Committee for Aeronautics (NACA) begins the operation of the Full-Scale Tunnel, a wind tunnel large enough to give researchers the ability to test the performance of actual aircraft.^[7]
Summer 1931 – Transcontinental and Western Air moves its headquarters from New York City to Kansas City, Missouri.^[8]

January 8 – Piarco Airport, the future Piarco International Airport, opens in Port-of-Spain, Trinidad.
January 9 – The Pratt-MacArthur agreement defines the United States Navy's naval air force as an element of the fleet that moves with the fleet and helps it carry out its missions. The agreement settles a lengthy controversy between the United States Army and the Navy over the role of naval aviation in overall national defense, as well as internal Navy debates over the role of naval air power.^[11]
January 28 – German explorer Gunther Plüschow and his engineer Ernst Dreblow are killed when their Heinkel HD 24 seaplane crashes near the Brazo Rico (part of Argentino Lake) in Patagonia.^[12]

February

Flying from Oran in French Algeria, the French aviators Antoine Paillard and Louis Mailloux fly a 15-kilometer (9.3-mile) circuit for over 50 hours in the Bernard 80 GR in an attempt to set a new unrefueled nonstop closed-circuit world distance record. They cover 8,168 kilometers (5,075 miles) before higher-than-expected fuel consumption forces them to land only 20 kilometers (12 miles) short of the record.

February 14 – The United States Congress authorizes a new award, the Air Mail Medal of Honor, which the President of the United States is to award to pilots who perform distinguished service in connection with U.S. Air Mail service.^[14] It will first be awarded in December 1933.^[15]
February 20 – The United States Senate ratifies the Havana Convention, in which 21 Western Hemisphere countries guarantee the right of innocent passage of aircraft without discrimination. The Convention also formulates the rules for international air navigation between the signatory countries relating to the marking of aircraft, landing facilities, prohibited transport, competency of airmen, and the right of each country to prescribe the route to be flown over its territory.^[7]
February 21 – After a Pan American-Grace Airways (Panagra) Ford Trimotor lands at Rodríguez Ballón Airport at Arequipa, Peru, armed revolutionary soldiers surround it.

- Zygmunt Puławski, one of Poland's leading aircraft designers, dies during the sixth flight of the PZL.12 flying boat prototype – which he designed and built – when the PZL.12 stalls after take-off due to a strong wind and crashes in Warsaw, Poland.
March 23–24 (overnight) – The French aviators Joseph Le Brix and Marcel Doret take off from Istres, France, in the prototype Dewoitine D.33 and fly a triangular course from Istres to Montpellier to Nîmes. Although fog forces them to shorten their course during the night of 23–24 March, they remain aloft continuously for 32 hours 17 minutes over a distance of 4,662 kilometres (2,897 mi) at an average speed of 151.36 kilometres per hour (94.05 mph). The flight sets seven new world records, for both duration and distance by an aircraft carrying a load of 500 kilograms (1,102 lb), both duration and distance by an aircraft carrying a load of 1,000 kilograms (2,205 lb), both duration and distance by an aircraft carrying a load of 2,000 kilograms (4,409 lb), and average speed by an aircraft over a distance of 2,000 kilometres (1,242.7 mi).^[18]

April 21 – Pitcairn-Cierva Autogiro Company pilot Jim Ray lands a Pitcairn PCA-2 autogiro on the White House lawn in Washington, D.C., for a ceremony in which U.S. President Herbert Hoover presents the Collier Trophy to autogiro manufacturer Harold Pitcairn. After the ceremony, Ray takes off again in the PCA-2.^[20]

May

May 4 – The first grounding of an aircraft type takes place when the United States Department of Commerce's Aeronautics Branch orders all Fokker F-10A aircraft out of passenger service after an investigation of the March 31 crash of a Transcontinental & Western Air Fokker F-10A discloses defective wing construction. Although most of the grounded planes eventually return to service, the loss of public confidence in the Fokker F-10A and the costly periodic inspection the Aeronautics Branch imposes on operators of it leads to the demise of the once-popular airplane.^[7]
May 5 – Polish pilot Stanisław Skarżyński completes a 25,050-kilometer (15,570-mile) tour around Africa in a PZL Ł.2. He began the tour on February 1.

May 28
- Walter E. Lees and Frederick Brossy set a new endurance record for a non-refueled flight, landing a Bellanca J2 Diesel aircraft at Jacksonville Beach, Florida, after remaining in the air continuously for 84 hours 32 minutes.^[21] The record will stand until July 1986.^[22]
- Flying the Pitcairn PCA-2 autogyro Missing Link, John M. Miller completes the first flight across the United States in a rotary-wing aircraft.

June 30
- Facing financial difficulties because of the Great Depression, an inability to procure an air mail contract, and the aftermath of the disappearance of one of its airliners in March, Australian National Airways (ANA), the first airline of that name, ceases scheduled services.^[25] Subsequently, it limits itself to operating joy flights, mostly around New South Wales,^[26] and offering pilot training services with a fleet of small aircraft.^[27]
The United States Department of Commerce's Aeronautics Branch (predecessor of the Federal Aviation Administration) has issued 48 approved repair station certificates. The certificates entitle repair stations in the United States to repair aircraft of types for which they are adequately equipped, eliminating the previous requirement for them to submit to the Aeronautics Branch detailed drawings of the repairs they make to licensed aircraft and, in some cases, a stress analysis. It had begun issuing the certificates in March 1930.^[7]

- The Hungarian aviators György Endresz (pilot) and Sándor Magyar (navigator) take off from Harbour Grace, Dominion of Newfoundland, in the Lockheed Model 8A Sirius Justice for Hungary to attempt a nonstop flight to Hungary. Despite thick fog, a compass that jams shortly after takeoff, and a mid-air engine failure, they reach the coast of Ireland in 13 hours 50 minutes — a new world record for a flight between North America and the Irish coast — and fly on toward Hungary, which they reach on 16 July. When the fuel flow to their engine is interrupted they make a forced landing at Bicske, 30 kilometres (19 mi) short of their planned destination at Mátyásföld, and arrive by car at Mátyásföld, where thousands of people greet them. The flight is the 15th successful transatlantic flight and the first to fly nonstop from North America so deep into Europe. It covers 5,770 kilometres (3,585 mi; 3,116 nmi) in 25 hours 20 minutes at a record average speed of 230 kilometres per hour (143 mph). Sponsored by the American-Hungarian Transatlantic Committee to draw attention to what Hungarian Americans view as the injustice of the Treaty of Trianon Hungary signed after its defeat in World War I, the flight also represents the first use of a transatlantic flight for political purposes.^[35]^[36]^[37]^[38]
