Analysis

Plt stated that he made an 'extra smooth landing' on rwy 11L and during the landing roll the right main landing gear collapsed. Examination of landing gear mounting bolt revealed evidence of an overload failure. The engineer that examined the bolt, nut, and mounting plate stated that there was no evidence of previous 'wear' around the bolt hole. There was evidence of dirt and grease found between the landing gear and the mounting plate. The wind was reported to be 040 degrees at 10 knots.
