An aircraft experienced engine failure during its final approach to Mactan Island, resulting in a crash into the sea.

What happened

During the final approach phase toward Mactan Island, the flight crew experienced mechanical difficulties involving the left engine. As a result of these technical issues, the aircraft lost altitude and impacted the ocean surface a few kilometers away from the coast.

Following the impact, the aircraft settled on the seabed at a depth of approximately 5 meters. Despite the crash, all 25 occupants were successfully rescued from the wreckage.

Findings

Preliminary observations indicate that the engine malfunction was characterized by an extremely high turbine temperature, which reached 850° C.

Probable cause

The aircraft experienced a loss of altitude following a technical failure in the left engine involving excessive turbine temperatures.
