Analysis

The plt was landing his Mooney M20E on a private grass airstrip. He said he lowered the manual landing gear and thought he felt the thumblock snap into place. Upon touchdown the landing gear folded up and the acft slid to a stop, resulting in substantial damage. The owner's manual cautions plts to make three checks to ascertain that the landing gear is down and locked: 1. Physical thumblock check; 2. Visual gear light check; 3. Audible gear horn check from retarded throttle. Asked if he ahd checked to see if he had a safe/gear down and locked green light indication, the plt said he thought he had. He said he didn't remember if the gear unsafe warning horn ever sounded.
