Aircraft Accident/Incident Report
San Antonio, Texas 78216
Monday, December 10, 2001 18:22 CST
NTSB Narrative Summary Released at Completion of Accident
During the approach to land, the pilot lowered the landing gear; however, the landing gear did not lock into position, and the gear safe indication did not illuminate. After recycling the landing gear several times and performing emergency procedures, the pilot still did not receive a down and locked indication. The pilot executed a low approach over the airport, and rescue personnel reported that all three gear appeared to be fully extended. While landing on the runway, the right main landing gear collapsed. During the aircraft recovery, the right main landing gear never locked into position, and a mechanic manually pulled the right downlock overcenter mechanism to the full lock position with resistance on the downlock. During an inspection by the operator, the landing gear system was cycled approximately 5 to 8 cycles, and the system functioned properly through all cycles.
NTSB Probable Cause Narrative
the failure of the right main landing gear downlock mechanism to engage for reasons undetermined.
