Crew failure to utilize the emergency system and a left main gear actuator bending contributed to the incident.
Description
The main gear would not lock in the down position, so an emergency landing was carried out, upon which the main gear collapsed. PROBABLE CAUSES: Failure of the landing gear-gearbox clutch assembly resulting on a 60Amp circuit breaker protecting the electrical motor which was running continually as a result of a faulty clutch assembly. Contributory factors: 1 Crews failure to use the emergency system when they became aware of the main system failure. 2 The bending of the left main gear actuator which rendered the emergency system inoperable.
Primary Cause
Faulty landing gear-gearbox clutch assembly leading to a 60Amp circuit breaker protecting the electrical motor, causing it to continuously run.Faulty landing gear-gearbox clutch assembly leading to a 60Amp circuit breaker protecting the electrical motor, causing it to continuously run.Share on:
