A maritime patrol aircraft suffered a total loss off the French coast due to fuel exhaustion, resulting in one fatality and two survivors during an emergency landing attempt.

What happened

The crew was conducting a maritime patrol mission along the French coastline when they encountered deteriorating weather conditions. During the cruise phase, both engines ceased functioning, necessitating an immediate emergency response. The pilot directed the aircraft toward Cape Gris Nez, located approximately 20 kilometers southwest of Calais, in an attempt to make a safe landing.

Despite the crew's efforts to manage the situation, the accident resulted in tragic consequences. The pilot lost his life in the incident. In contrast, both air gunners aboard the aircraft were successfully rescued and survived the event. The flight was operated by the 48th Squadron.

Findings

Official investigations determined that the root cause of the dual engine failure was fuel exhaustion. This critical lack of fuel rendered the aircraft inoperable, leading to the forced landing attempt and subsequent loss of life.

Probable cause

The accident was caused by double engine failure resulting from fuel exhaustion.
