Accident Overview
A flight instructor and a dual student were conducting an instructional flight when the airplane sustained substantial damage during a hard landing. The flight instructor held a multi-engine airplane instructor rating and was providing training to the other pilot, who held a commercial pilot certificate with single- and multi-engine airplane ratings, as well as a flight instructor certificate with a single-engine airplane rating. The dual student was undergoing training in preparation for the multi-engine flight instructor rating.
Sequence of Events
The flight instructor intended for the student to execute a simulated forced landing on the remaining runway immediately after liftoff. He instructed the dual student to back taxi the full length of the runway. The tower subsequently cleared the flight for takeoff followed by an immediate landing. The dual student held the brakes and applied full engine power. Upon reaching full power, the student released the brakes and began the takeoff roll. After liftoff, the student established the airplane in a climb at 88 knots.
According to the instructor, upon reaching an altitude of 200 feet above ground level (agl), he instructed the student to "simultaneously reduce both throttles to idle while pitching for a landing attitude that maintained 88 knots." The resulting descent rate "did not appear favorable," so at about 100 feet agl, the instructor "commanded" the dual student to execute a go-around. Full engine power was applied, but the descent continued until the airplane contacted the runway in a "flat attitude." It subsequently bounced back into the air. The stall warning horn sounded shortly before runway contact.
The flight instructor stated that he assumed control of the airplane at this point and decided to continue the go-around since the engines seemed to be producing full power. During the flight around the traffic pattern, the rudder and stabilator were "less responsive than usual." He subsequently executed a no-flap landing on the departure runway.
Post-Accident Inspection
A post-accident inspection revealed that the fuselage skin on the left and right sides, forward of the windshield, was buckled. The left main landing gear strut was bent aft approximately 90 degrees. Both engine propellers were in the feathered position, and the blade tips were curled and twisted, consistent with runway contact.
