Did the check pilot start loading the handling pilot up with emergencies leading up to the accident
Have only once heard of a check pilot pulling emergencies at night, and he died doing it, though it was fixed wing - Beech Baron. Good friend, well experienced, had a small aviation business and doing a check ride on a new employee. Pulled an engine after T/O and flew into the side of a hill where you could see the prop slash marks as they were in the process of restarting the shut down engine. Didn't have his shoulder sash on, hit head and bled to death. Crashed about 0100 and discovered by a passing motorist at 0600 when investigating why the flashing red light up the hill. Body still warm, showed some falling between the cracks on SAR watch by authorities. Pilot under check survived but gave up flying for school teaching, recently returned to flying privately after a hiatus of some 40 years.
