On November 1, 1994, about 1310 eastern standard time, a Cessna 402C, N5715C, registered to Airways International Inc., operating as a 14 CFR Part 135 scheduled domestic passenger flight, experienced a collapse of the left main landing gear on landing rollout at the Fort Lauderdale-Hollywood International Airport, and collided with the runway lighting system. The airplane sustained substantial damage. The airline transport-rated pilot and two passengers reported no injuries. Visual meteorological conditions prevailed and an instrument flight plan was filed. The flight originated from Miami International Airport, 25 minutes before the accident. Examination of the landing gear by the FAA and Airways International Inc, maintenance personnel revealed a failure of the left main landing gear trunnion. Review of airplane logbooks revealed no recorded history of hard landings, or previous landing gear damage. Examination of pieces from the left main landing gear upper barrel and trunion assembly was performed by the NTSB materials laboratory. The examination revealed the fractures were representative of overstress separations. No evidence of fatigue or other type of preexisting cracking was found. (For additional information see NTSB Metallurgist's Factual Report No. 95-17). Components retained for further testing were released to Mr. Jagdesh Remkhalawam, Aero Parts International, Miami, Florida, on December 13, 1994.
