Mc Clellan-Palomar Airport
Aircraft Accident/Incident Report

Carlsbad, California 92008
Sunday, September 23, 2001 12:37 PDT

NTSB Narrative Summary Released at Completion of Accident

During training, the flight instructor (CFI) directed his student to perform a full touchdown autorotation, and the maneuver commenced. While descending, the student allowed the main rotor rpm to decay. Also, the CFI recognized that the desired touchdown location was farther than their flight profile would allow, so he attempted to "stretch the glide distance" by using collective rather than by adding engine power. The landing flare was delayed, and when touchdown occurred the main rotors impacted the tail boom.

NTSB Probable Cause Narrative

A hard landing due to the dual student's failure to maintain main rotor speed, his improper landing flare, and the flight control interference by the flight instructor.
