Boerne Stage, TX, USA
N550JW
CESSNA 310K
The pilot stated that he used the checklist and placed the landing gear handle in the “down” position, but did not check the annunciator lights. During landing, the gear collapsed. Postaccident examination of the airplane revealed that the landing gear circuit breaker had opened. Runway scrapes showed all three gears were partially extended when the airplane touched down, indicative that the gear extension was in progress when the wheels touched the runway. The airplane was placed on jacks and the nose gear was pulled down by hand where it locked into position. The right main landing gear was also pulled down by hand and it locked in position. The left main landing gear could not be extended due to spar damage, but testing of the squat switch revealed no anomalies.
On September 27, 2010, approximately 1550 central daylight time, a Cessna 310K, N550JW, registered to and operated by Urban Air, LLC, and piloted by an airline transport certificated pilot, was substantially damaged when it landed wheels up at Boerne Stage Field (5C1) Boerne Stage, Texas. Visual meteorological conditions (VMC) prevailed at the time of the accident. The personal flight was being conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. The pilot and passenger on board the airplane were not injured. The cross-country flight originated at La Porte Municipal Airport (T41), La Porte, Texas, approximately 1500, and was en route to Boerne Stage. The pilot was asked to complete and return NTSB Form 6120.1-2, Pilot-Operator Aircraft Accident Report. He never did. The following is based on what was reported by the Federal Aviation Administration (FAA) inspector who went to the accident site: The pilot said he used the checklist and placed the landing gear handle in the DOWN position, but he admitted he did not check the annunciator lights. He said the gear collapsed on landing. An FAA inspector examined the airplane and found the landing gear circuit breaker had opened. Runway scrapes indicated all three gears were partially extended. The airplane was placed on jacks, and the nose gear was pulled down by hand and it locked in position. The right main landing gear was also pulled down by hand and it locked in position. The left main landing gear could not be extended due to spar damage, but the squat switch tested normal.
The pilot’s failure to ensure that the landing gear was extended prior to landing, resulting in a landing on the partially extended landing gear.
