Aircraft involved
Probable cause & findings
The pilot's unintentional retraction of the landing gear during the landing roll.
Factual narrative
The single-engine rated pilot reported that, during a multi-engine check ride in an airplane with retractable landing gear, the fight examiner requested he conduct several touch-and-go landings. During the landing roll, he mistakenly retracted the landing gear, the airplane than skid down the right side of the runway, and came to rest at a taxi intersection. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
