This is a list of aviation-related events from 1927:

Events

• The United States Navy 's USS Langley (CV-1) becomes the first aircraft carrier to operate a multi-engine aircraft, the twin-engine Douglas T2D-1. ^[1]
• The British aircraft carrier HMS Argus brings Fleet Air Arm of the Royal Air Force Fairey IIID aircraft to support the Shanghai Defence Force against rebel Chinese forces. The aircraft fly as landplanes from the Shanghai racecourse and as seaplanes from the Huangpu River. ^[2]
• Germany's lead in commercial aviation is such that during the year German airlines fly greater distances with more passengers than the airlines of France, Italy, and the United Kingdom combined. ^[3]

January

• January 1 – Prompted by the increase in air traffic over Europe, a regulation goes into effect in the United Kingdom requiring the installation of wireless telegraphy equipment aboard any aircraft capable of carrying 10 or more people including crew and that such aircraft carry a special operator for the equipment. The use of radio telephony is limited to aircraft carrying five to nine people including crew. ^[4]
• January 7 – Imperial Airways commences a regular service from Basra to Cairo via Baghdad, the first of its Empire "trunk routes."
• January 15 – Boeing Air Transport is formed, to carry airmail between Chicago and San Francisco. It eventually will become United Airlines.

February

• February 13 – Regia Aeronautica (Italian Royal Air Force) pilots Francesco de Pinedo and Capitano Carlo Del Prete, accompanied by their mechanic Sergente Vitale Zacchetti, take off from Cagliari, Sardinia, in the Savoia-Marchetti S.55 flying boat Santa Maria to begin their "Four Continents" flight, during which the plan to fly to Africa, cross the South Atlantic to Brazil, make several stops in South America and the Caribbean, visit the United States and Canada, and cross the North Atlantic to recreate the 1919 transatlantic flight of the United States Navy Curtiss NC-4 flying boat before returning to Italy. ^{[5] [6]}
• February 16 – After stops at Villa Cisneros in Spanish Sahara and Bolama in Portuguese Guinea, Pinedo, Del Prete, and Zacchetti attempt to take off from Bolama to cross the Atlantic Ocean to Brazil. Sweltering conditions prevent their plane from becoming airborne until they dump a large quantity of gasoline, forcing them to fly to the Cape Verde Islands instead, where cooler conditions prevail. ^[5]
• February 23 – Pinedo, Del Prete, and Zacchetti cross the Atlantic, flying from the Cape Verde Islands to Fernando de Noronha, where the Brazilian Navy protected cruiser Almirante Barroso meets them and tows their flying boat into port. The next day, they fly to Natal, Brazil, to begin the South American phase of their "Four Continents" flight. ^[5]

March

• March 9 – United States Army Air Corps Captain Hawthorne C. Gray sets an unofficial U.S. balloon altitude record of 28,510 feet (8,690 m) in a balloon with an open basket launched from Scott Field, Illinois. He passes out from hypoxia in the thin air, regaining consciousness only just in time to drop ballast and slow his fall after the balloon descends on its own. ^{[7] [8] [9]}
• March 14 – Pan American Airways is formed to carry airmail on the Key West-Havana route.
• March 16 – After stops at various cities in South America including Rio de Janeiro, Brazil, Buenos Aires, Argentina, Montevideo, Uruguay, and Asunción, Paraguay, the Italian aviators Francesco de Pinedo and Carlo Del Prete and their mechanic Vitale Zacchetti continue their "Four Continents" flight by beginning a long leg over the dense jungle of Brazil's Mato Grosso region. At one point, their Savoia-Marchetti S.55 flying boat Santa Maria is towed by a Brazilian river boat for 200 miles (320 kilometers) along the Paraguay River in search of a suitable takeoff area after a refueling stop, and it takes them until March 20 to complete their crossing of the Matto Grosso and land at Manaós, Brazil. It is history's first flight over the Mato Grosso. ^[5]
• March 21 – John Rodgers Airport (the future Honolulu International Airport) is dedicated in Honolulu, Territory of Hawaii. ^[10]
• March 25 – Belgrade International Airport opens in Belgrade in the Kingdom of Yugoslavia.^{[ citation needed ]}

April

• April 1 – Waldemar Roeder achieves a new world distance record for an aircraft with a 2,000-kilogram (4,410-pound) payload, flying 1,013.18 kilometers (629.56 miles) in 7 hours 52 minutes in a Junkers G 24L. ^[11]

An accidental fire breaks out and destroys the plane; its engines sink 60 feet (18 meters) to the bottom of the lake and are not recovered until April 19. The three Italians will fly to San Diego, California, as passengers on a United States Navy plane and then travel by train to New York City to meet a new S.55 shipped there by the Italian Fascist government so that they can continue their flight. The new plane will arrive in New York by ship on May 1. ^[5]
• April 10 – In a single flight in a Junkers G 24L, Hermann Roeder achieves two new world speed records for an aircraft with a 2,000-kilogram (4,410-pound) payload, averaging 175.75 km/h (109.21 mph) over a distance of 500 kilometers (310 mph) and 179.24 km/h (111.37 mph) over a distance of 100 kilometers (62 miles). ^[11]
• April 16 – The Portuguese Military Aviation seaplane Argos, piloted by Sarmento de Beires and accompanied by Duvalle Portugal (co-pilot), Jorge de Castilho (navigator) and Manuel Gouveia (mechanic), makes the first night aerial crossing of the South Atlantic which was the first complete night-time flight of the Atlantic, taking off from Portuguese Guinea and landing in Brazil, where they arrived after totaling 2,595 kilometers on an 18-hour, 12-minute flight.
• April 26 – Attempting a test flight with a full load of gasoline of the Keystone K-47 Pathfinder American Legion (registration NX179), which they plan to use in an American Legion-sponsored attempt to win the Orteig Prize by making the first nonstop transatlantic flight from New York City to Paris, United States Navy Commander Noel Guy Davis and Lieutenant Stanton Hall Wooster crash on takeoff from Langley Field in Hampton Roads, Virginia. Both men are killed. ^[12]

May

• May 1 – Imperial Airways introduces its luxury "Silver Wing" service between London and Paris.

Departing Paris on 20 April, they have followed the route Paris-Belgrade-Aleppo-Basra-Jask-Karachi-Bombay-Karachi-Jask-Basra-Aleppo-Belgrade. They make the flight to spur interest in investment in the Kingdom of Yugoslavia′s first civilian airline, Aeroput. Investment in Aeroput increases greatly, saving the new airline from abolition due a lack of capital.^{[ citation needed ]}
• May 4 – United States Army Air Corps Captain Hawthorne C. Gray sets an unofficial record for the highest altitude reached by a human being, attaining 42,470 feet (12,940 meters) in a balloon with an open basket over Belleville, Illinois. Because of the rapid descent of the balloon, he parachutes out at 8,000 feet (2,400 meters), disqualifying him from recognition for an official record by the Fédération Aéronautique Internationale (FAI), which requires that a balloonist land with his craft in order to set an official record. ^{[7] [8] [9]}
• May 5 – The Société Générale des Transports Aériens Farman F.61 cargo aircraft F-ADFN disappears over the Atlantic Ocean during a flight from Saint-Louis Airport in Saint-Louis, Senegal, to Petrolina Airport in Petrolina, Brazil. Its two crew members are never found. ^[13]

Forced to ditch in the Persian Gulf, the flight nonetheless achieves a nonstop record 3,420 mi (5,500 km) which will be beaten within hours by Lindbergh.
  • Charles Lindbergh flies the Ryan monoplane Spirit of St. Louis across the Atlantic nonstop from Roosevelt Field in New York City to Paris–Le Bourget Airport. It is the first solo transatlantic flight, over a distance of 3,610 mi (5,810 km); 3,137 nmi), and it sets a new nonstop flight distance record. Lindbergh wins the Orteig Prize for the first nonstop flight from New York to Paris.
• May 22–23 – Pinedo, Del Prete, and Zacchetti depart Trepassey Bay in the Dominion of Newfoundland, planning to cross the Atlantic Ocean to the Azores, refuel, and then fly on to Portugal, retracing the transatlantic flight route of the United States Navy Curtiss NC-4 flying boat in 1919, but they run low on fuel due to unfavorable weather. Pinedo is forced to land the Santa Maria II on the ocean and be taken under tow by a Portuguese fishing boat and an Italian steamer for the final 200 miles (320 km) to the Azores, where the plane arrives at Horta on May 30. ^{[5] [15]}
