A Swearingen SA227-AC Metro III, registration LV-VDJ, suffered a runway excursion after the right-hand main landing gear collapsed during landing on runway 18 at Mendoza-El Plumerillo Airport, Argentina.

Probable Cause:

Conclusions regarding factors related to the accident:
- During the landing phase, the right main landing gear collapsed and caused the aircraft to leave the runway on the right side.
- The collapse of the right main landing gear was caused by the fracture of both drag braces.
- According to the report issued by the intervening laboratory, no pre-existing cracks or progressive advancement mechanisms were found that influenced the weakening of the aforementioned parts.
- The fracture surfaces of both components showed ductile fracture characteristics, which suggest that these components were exposed to loads above the limits for which they were designed.
- The inner drag brace fractured in the first instance, which probably caused the outer drag brace to fail to withstand the stress and fracture accordingly.
- The aircraft's CVR had the magnetic tape locked, so it was not recording at the time of the event.
