The pilot-in-command, a certificated flight instructor, was providing turbine transition instruction to the second pilot. The accident airplane had been modified by the installation of a Pratt & Whitney PT6 turbine engine. The instructor pilot stated that the propeller governor control was causing 'the engine to surge.' He added that just prior to touchdown on runway 31, while the second pilot was manipulating the controls, the engine again surged, and the airplane landed hard. In the pilot-in-command's written report, and during a later telephone conversation, he reported that during the previous landings, the second pilot failed to 'carry power so as not to land hard again.' The first pilot said that he then instructed the second pilot as to the differences of a turbine engine vs. a piston engine. He wrote: 'I watched very closely until we were over the runway, and once again, quick as a cat, we stalled and hit hard.' The airplane's fuselage sustained substantial damage.
Probable Cause: The certificated flight instructor's inadequate supervision of the duel student. Factors associated with the accident were the student's inadvertent stall, and a surging turboshaft engine.
