The NTSB's narrative final · quoted from the NTSB record
THE AIRCRAFT WAS MAKING A RIGHT-HAND TURN IN THE RUN-UP AREA AT A SLOW SPEED WHEN THE LEFT MAIN LANDING GEAR COLLAPSED. THE SIDE BRACE FOR THE MAIN LANDING GEAR IS ATTACHED TO A CASTING, WHICH IN TURN IS BOLTED TO THE INBOARD WING RIB IN THE LANDING GEAR WHEEL WELL. EXAMINATION REVEALED THAT THE WING RIB WEB CRACKED AROUND THE CASTING, WHICH ALLOWED THE SIDE BRACE TO MOVE AND THE LANDING GEAR TO COLLAPSE. PORTIONS OF THE CRACK APPEARED DISCOLORED AND OLD. REVIEW OF THE AIRCRAFT MAINTENANCE RECORDS REVEALED NO HISTORY OF LANDING GEAR DAMAGE OR HARD LANDING RELATED MAINTENANCE ACTIVITY. THE AIRCRAFT WAS LAST INSPECTED DURING AN ANNUAL INSPECTION 7 MONTHS AND 60 FLIGHT HOURS PRIOR TO THE ACCIDENT. CESSNA AIRCRAFT COMPANY REPORTED THAT IN RESPONSE TO CRACKS FOUND ON THE INBOARD WING RIB WEB AROUND THE SIDE BRACE FITTING, SERVICE LETTER ME76-2 WAS ISSUED ON JANUARY 5, 1976.
