NTSB Narrative Summary Released at Completion of Accident
The airplane experienced a landing gear collapse while on the landing roll. After a normal touchdown, the airplane rolled down about 1/3 the runway length and the left main landing gear collapsed, followed by the right main landing gear; the nose gear collapsed when the airplane came to rest. An airplane mechanic stated that during a post accident inspection of the airplane he found no defects or faults that could have resulted in a landing gear failure. He further noted that the squat switch was intact and operated normally. A Federal Aviation Administration (FAA) inspector examined the airplane and stated that the main landing gear doors were crushed outward; an indication that the landing gear were extended when the collapse occurred.
NTSB Probable Cause Narrative
a collapse of the landing gear for undetermined reasons.
