Incident Overview
During a commercial pilot practical test for airplanes, single engine, land, the pilot had advanced to the takeoff and landing phase. He lowered the landing gear and extended the flaps. He thought the GEAR DOWN green light had illuminated and announced "gear down and locked." The sun came through the rear window and the glare illuminated the landing gear indicator lights.
Landing Sequence
As the airplane approached the runway threshold, the pilot retarded the throttle. The gear warning horn did not sound. The airplane landed wheels up. After landing, the landing gear warning horn began sounding.
Post-Landing Inspection
The landing gear selector was in the DOWN position. The nose gear doors were open, and the nose gear was partially extended. The main landing gear doors were partially open, but the main landing gear was not extended.
