NTSB narrative

The pilot was taking a multi engine class certification check ride. The pilot examiner stated that the applicant pilot had been flying a Piper PA23-160 for his multi engine training. The PA23 cockpit is set up with the landing gear selector handle on the right side of the power quadrant and the flap selector on the left. The PA23 was in the maintenance shop and the applicant was given the Piper PA39 for his flight test. The PA39 cockpit is set up with the landing gear selector handle on the left side of the power quadrant and the flap selector on the right. The examiner stated that during the traffic pattern he personally checked that the landing gear handle was in the DOWN position, with three green indicator lights. The aircraft made a normal landing. The examiner said that during the landing roll out his attention was distracted momentarily by locating the radio microphone. When he looked up again, the examiner saw the aircraft settling down on the runway with the landing gear selector handle in the UP position. According to the pilot's statement, he said that he was reaching for the flap handle to retract the landing flaps and mistakenly moved the gear handle instead.

Probable cause

the pilot's inadvertent movement of the landing gear selector switch to the up position. A factor in the accident was the difference in cockpit switch layout between the PA23 and PA39 aircraft.
