## Discrepancy

PILOT REPORTED THAT AFTER LANDING THAT THE RT MLG COLLAPSED ON LANDING.  AFTER INVESTIGATING IT WAS FOUND THAT PN 401-335 (AN4-40A) BOLT AND PN 67502-00 RETAINER ASSY HAD BACKED OUT OF THE TRUNNION ASSY (PN 96766-17).  THIS CAUSED PN 67040-15 (FITTING ASSY- FWD TRUNNION) TO FAIL WHEN THE WEIGHT OF THE ACFT WAS ON THE LANDING GEAR AND SUBSEQUENTLY CAUSING A COLLAPSE AND DAMAGE TO THE TOP SKIN AND BOTTOM OF THE WING.
