Night Takeoff Accident Involving Twin-Engine Aircraft at Singapore-Seletar (PP103)

Singapore-Seletar, SingaporeTakeoff (climb)

On March 27, 1946, a Short S.25 Sunderland (registration PP103) operated by Royal Air Force - RAF was involved in an aviation accident near Singapore-Seletar, Singapore during takeoff. 13 people were killed. Investigators recorded the probable cause as: Poor coordination by the crew resulted in the inadvertent reduction of power on both left engines during the initial climb, leading to a stall and subsequent crash. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 8 related events involving the same aircraft type or operator are linked below.

A heavily loaded twin-engine aircraft crashed into the Seletar River shortly after a night takeoff from Singapore-Seletar Airport, resulting in thirteen fatalities and eight injuries due to inadvertent power loss on both left engines.

What happened

The incident occurred during a night departure from Singapore-Seletar Airport. Shortly after lifting off, the aircraft was in the initial climb phase, reaching an altitude of approximately 200 feet. At this stage, power was lost on both engines located on the left side of the fuselage. The aircraft was carrying a heavy load and traveling at low airspeed when it entered a stall condition. Unable to recover, the plane descended and impacted the waters of the Seletar River. The crash resulted in the destruction of the airframe. A total of thirteen occupants were killed, while eight others sustained injuries.

Findings

Investigations into the event identified crew coordination issues as a primary factor. Specifically, the flight engineer inadvertently reduced power settings on both left engines during the critical initial climb phase. This action led to the loss of thrust required to maintain lift at low speeds, causing the aircraft to stall and crash.

Probable cause

Poor coordination by the crew resulted in the inadvertent reduction of power on both left engines during the initial climb, leading to a stall and subsequent crash.
