Aviation Accident Summary DEN03LA007

Englewood, CO, USA

Aircraft #1

N8084D

Mooney M20J

Analysis

The pilot said that when he put the landing gear down, everything "sounded and felt normal," but he had an unsafe gear indication. He made a pass over the airport, and tower personnel indicated that all three landing gear appeared to be down and locked. The pilot requested that a Mooney mechanic also confirm the position of the gear. After working with a mechanic to manually lock the gear into place, the mechanic stated that the gear did appear to be down and locked, and that most often the problem was with the indicator rather than the gear itself. Although the unsafe light was still illuminated, the pilot decided to land. During the landing roll, the gear collapsed and the airplane exited the south side of runway 28 into the dirt. According to the pilot's accident report, the reason for the collapse of the landing gear had not been determined.
