Accident Overview
The airplane collided with trees near a rock quarry while practicing a simulated engine out forced landing procedure.
Flight Details
The flight involved a certified flight instructor (CFI) and a pilot under instruction (PUI). During the maneuver, the CFI called for termination of the forced landing procedure. The PUI delayed executing the proper go-around procedures.
Sequence of Events
The student pilot left the flaps at the 30-degree position, causing the airspeed to become slow enough to activate the stall warning horn. The CFI then called for the flaps to be set to 20 degrees and to maintain airspeed. Subsequently, the CFI called for flaps to 10 degrees, but the student retracted them to 0 degrees. The airplane entered an excessive sink rate, and the CFI was unable to recover before the airplane impacted trees.
