On September 2, 1995, a Cessna 172 (registration N7154T) was involved in an aviation accident near Quakertown, PA. Investigators recorded the probable cause as: the pilot's failure to maintain directional control, and the pilot's improper use of the wing flaps, which resulted in an inadvertent stall, and contact with trees. A factor was the crosswind. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.
During landing practice, a student pilot encountered an updraft on the fifth approach and initiated a go-around. Crosswind drift and a flap retraction error led to a stall and crash.
Approach and Go-Around
The student pilot was practicing takeoffs and landings. On the fifth approach, she encountered an updraft and added power to execute a go-around. A crosswind from the right caused the airplane to drift left, away from the runway centerline toward trees.
Flap Retraction Error
The wing flaps were extended 40 degrees. When she attempted to retract the flaps by 10 degrees, she inadvertently retracted them 20 degrees instead. The airplane continued to drift left, passing over the tops of trees.
Stall and Impact
To avoid the trees, she pulled back on the yoke. The airplane stalled and subsequently crashed.
