Federal Aviation Administration / Flight Standards District Office; Houston, Texas
Location: Houston, TX
Accident Number: CEN20LA185
Date & Time: 05/19/2020, 1930 CDT
Registration: N501KM
Aircraft: Cessna 501
Injuries:1 None
Flight Conducted Under: Part 91: General Aviation - Personal
On May 19, 2020, about 1930 central daylight time, a Cessna 501, N501KM, sustained substantial damage when it was involved in and accident near Houston, Texas. The pilot was not injured. The airplane was being operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight.
After a normal instrument flight rules (IFR), 2-hour flight from Gainesville, Florida (GNV), the pilot was setting up to land at his final destination (HOU). The pilot reported that during his final approach to runway 13 at HOU, he lowered the landing gear and received 2 of 3 green lights on his landing gear position indicators. The left main landing gear light was not illuminated and a warning horn sounded. The pilot recycled the landing gear with the same result. He reported the situation to HOU tower and asked if they could visually see whether all three landing gear were down. The pilot stated that the HOU tower affirmed that all three landing gear were down. The pilot also stated that a commercial airliner that was taxiing toward the main terminal radioed that they observed all three landing gear were down.
The pilot reported that according to the Pilot Operating Handbook (POH), he initiated an aggressive bank right, followed abruptly by a bank left in an attempt to generate sufficient lateral G-force on the landing gear. The HOU tower asked the pilot his intentions, and the pilot informed them that he would proceed to land. Upon touchdown on runway 13R, the left main landing gear collapsed, and the airplane veered left and came to a stop in a grassy area adjacent to runway 13R and Taxiway Lima, resulting in structural damage to the left wing tip and underbelly of the airplane. The pilot exited the airplane and airport emergency services responded. Recovery personnel manually lifted and locked the left main landing gear down, and the airplane was towed to a hangar facility. The pilot reported that his decision to land was made because the left main landing gear indicator light had malfunctioned in years past, and it was found that the light had malfunctioned, and not the landing gear.
Under the supervision of an FAA airworthiness inspector, the landing gear was examined at a certified manufacturer repair facility at HOU. The landing gear was cycled about 30-times with various hydraulic pressures, and the left main landing gear actuator did not lock in the full down position. The only way to attain a locked left main landing gear was to manually push the gear outward to the down and locked position. When the landing gear was pushed into the locked position, the left main landing gear down indicator light illuminated green, and it appeared that the internal locking mechanism of left main landing gear actuator was not functioning. According to the repair facility, the actuator was a component that is replaced at interval (37,000 cycles) or as needed. The FAA inspector reported that the airplane's logbooks did not show any recent entries concerning anomalies with the left main landing gear.
