## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - nonmechanical, maneuvering
  - throttle/power control - improper use of, pilot in command(cfi) (cause)
  - overconfidence in aircraft's ability, pilot in command(cfi) (contributing factor)
- Hard landing, descent - emergency

## Analysis

DURING AN INSTRUCTIONAL FLIGHT, A POWER RECOVERY WAS ATTEMPTED AT THE COMPLETION OF A PRACTICE AUTOROTATION. POWER WAS APPLIED AND THE ENGINE LOST POWER. THE AUTOROTATION WAS COMPLETED TO THE PRESELECTED PRACTICE FIELD AND THE HELICOPTER ROLLED OVER AFTER A LANDING SKID COLLAPSED. THERE WERE NO MECHANICAL DIFFICULTIES WITH THE AIRCRAFT AND THE ENGINE TEST RUN WAS SUCCESSFUL. THE FLIGHT INSTRUCTOR RECOMMENDED THAT A POWER CHECK BE PERFORMED AT LEAST 500 FT. AGL.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
