Accident Overview
On October 27, 2012, at about 1235 Pacific daylight time, a Cessna P210N (registration N43CE) experienced a landing gear collapse during the landing roll at Oakland Metropolitan International Airport (OAK), California. The aircraft was operating under Title 14 Code of Federal Regulations Part 91. The private pilot, who was the sole occupant, was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which originated from Salt Lake City International Airport (SLC), Utah, at about 1100 mountain daylight time.
Pilot Actions and Gear Extension
The pilot reported extending the landing gear to the down position during the approach, approximately five miles from the airport. As the gear extended, he heard the sound of the gear motor and felt a pitch change in the airplane. However, he did not check whether the green landing gear position indicator light was illuminated and did not visually confirm that the landing gear was down and locked.
Landing Gear Collapse
During the landing roll, the main landing gear collapsed about 600 feet from the touchdown point, while the nose gear remained down and locked.
Post-Accident Examination
Examination of the airplane by the pilot revealed minor damage to accessories attached to the underside of the fuselage. Subsequently, he observed that the gear pump circuit breaker was out. After resetting the circuit breaker, a gear swing was accomplished, which resulted in normal operation.
Checklist Review
A review of the normal procedures section in the Pilot Operating Handbook indicated that the Before Landing checklist (step 4) requires checking that the green landing gear position indicator light is illuminated and visually observing that the main landing gear is down and locked. The emergency procedures call for checking that the landing gear and gear pump circuit breakers are in, in the event of a landing without positive indication of gear locking.
