Test

The aircraft was carrying 11 people (five engineers from Short Brothers and six BOAC crew members) who were performing a test flight. Upon landing in the Solent, just prior to touchdown, the seaplane was caught by strong winds, hit the water surface and sank off Netley, southeast of Southampton, Hampshire. All 11 occupants were quickly rescued while the aircraft was lost.

The crew was engaged in a test flight following maintenance. After takeoff from Trondheim-Værnes Airport, while in initial climb at a height of some 80 meters, the twin engine aircraft banked right, dove into the ground and crashed in a snow covered field. The aircraft was totally destroyed and all three occupants were killed.

The crew consisting of 15 pilots and engineers was engaged in a test flight following engine maintenance. The departure was attempted by night and on rough sea. During the takeoff procedure completed off Saint-Mandrier-sur-Mer, while at a speed of 100 km/h, the seaplane registered EJ163 (7.F-6) hit three successives waves then broke in two just before the wings. The front part including the cockpit sank rapidly while the rear part came to rest few hundred yards off shore. Four crew members were killed, seven others were injured and four were unhurt.

The crew left Marseille-Marignane to perform a test mission on this third example. After a 4 hours and 20 minutes flight, the crew returned to his base. On landing on the Étang de Berre, the seaplane bounced four times, took off and flew less than 20 meters over hangars. At 1725LT, the crew made a second attempt to land when the aircraft hit the water surface, bounced three times and plunged into the water, hit the bottom and eventually came to rest. All eight crew members were unhurt but the aircraft was severely damaged and later considered as a complete write off.

The crew left Marseille-Marignane Airport at 1416LT for a test flight. While cruising about 45 km north of Toulon, the four engine aircraft went out of control, dove into the ground and crashed in a wooded area. The airplane was destroyed by impact forces and all six crew members were killed. Built in November 1948, the aircraft made its first test flight on November 24, 1948 and was performing here its 34th test flight and already completed a total of 60 flying hours. Built for the Institut Géographique National (IGN) for aerial photography and stratospheric mission, this model was the first prototype. Following this accident, the project was abandoned.

Crashed in unknown circumstances into the Seine River near Les Mureaux Aerodrome. The crew fate remains unknown. This was the first prototype of the SCAN-30, a G-44 Widgeon built under licence in France by Société de Construction AéroNavale (SCAN).

The crew consisting of pilots and engineers of the Bristol Aeroplane Company left Bristol-Filton Airport at 1003LT for a test flight to obtain engine and propeller datas in specific flight conditions. While cruising off the Isle of Portland, the twin engine aircraft went out of control and dove into The Channel. Some debris were found 26 km off the Portland's lighthouse and all seven crew members were killed.

The crew was engaged in a test flight when the seaplane crashed in unknown circumstances into the Río Pastaza. Both crew members were killed.

The crew was engaged in a test flight. Shortly after takeoff from Guidonia AFB, the pilot encountered control problems and decided to attempt an emergency landing. The aircraft belly landed in a field located in Tor Sapienza, about 15 km southwest of Guidonia. On ground, the aircraft slid for several yards and hit a boy aged 11. While all five crew members were uninjured, the boy was killed and the aircraft was damaged beyond repair.

The crew consisting of two pilots and two engineers was completing a test flight on this first 34 Twin Quad prototype (certification program). Just after liftoff, while in initial climb, the twin engine aircraft stalled and crashed. The copilot was killed while three other occupants were injured. The aircraft was destroyed. Following this accident, the project was terminated.
