Incident Details
The flight, en route from Arequipa to Juliaca, encountered a problem with the right main landing gear. The gear jammed and remained blocked in its main wheel well. The crew attempted to lower the gear using the manual system, but was unable to do so.
Diversion and Emergency Landing
With no other options, the crew decided to divert to Tacna for an emergency landing. The aircraft landed 280 meters past the threshold of runway 20. After touchdown, the aircraft veered to the right and came to rest 600 meters after landing.
Evacuation
All 65 occupants evacuated safely. The aircraft was not repaired and the incident ended without any reported injuries.
Probable Cause
The official investigation determined the probable cause to be the rupture of the shaft lower assembly, caused by material fatigue. This part is located inside the right main landing gear well in a difficult-to-reach position, hidden within other components. The rupture prevented the landing gear system from completing the secured gear down cycle and also prevented the emergency manual landing gear lowering system from operating. The crew, with no other options, made the best decision to perform a forced landing. The part was within its inspection time limits.
