Contributing factors include the instructor's inadequate supervision, the instructor's inadequate recovery from a bounced landing, and the two parked aircraft. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - aircraft control - not maintained, unqualified person (cause) - supervision - inadequate, pilot in command(cfi) (contributing factor) - On ground/water collision with object, landing - recovery from bounced landing - inadequate, pilot in command(cfi) (contributing factor) - object - aircraft parked/standing (contributing factor) ## Analysis The pilot reported that, a non-rated passenger, his wife, was flying the airplane and was attempting to land on runway 34. During the landing, the airplane "bounced twice" before the pilot, also a certified flight instructor, took the controls and applied full power for a go-around. The pilot stated that the airplane bounced a third time, veered to the left, and departed the left side of the runway. The airplane became airborne, crossed over the median between the runway and taxiway, and then touched down on the taxiway. The pilot stated that he attempted to regain control of the airplane, but the airplane continued to roll into the parking area and it struck a Taylorcraft F-21, and a Beech B35. The impact resulted in substantial damage to the Cessna's vertical stabilizer and rudder, substantial damage to the Taylorcraft's empennage and right wing, and substantial damage to the Bonanza's left wing. ## Factual narrative On December 8, 2003, at 1200 mountain standard time, a Cessna 150H, N6935S, was substantially damaged when it struck two parked airplanes during landing at Skypark Airport (BTF), Bountiful, Utah.
