THE FAILURE OF THE PILOT TO RETAIN CONTROL OF THE AIRCRAFT.

## Sequence of events

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

- Loss of control - in flight, hover
  - aircraft control - not maintained, pilot in command (cause)
  - inadequate initial training, flight instructor(on ground) (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACCIDENT HELICOPTER COLLIDED WITH TERRAIN DURING HOVER FLIGHT AND ROLLED OVER DURING SOLO FLIGHT. THE HELICOPTER WAS SUBSTANTIALLY DAMAGED ALTHOUGHT THE STUDENT PILOT AT THE CONTROLS WAS NOT INJURED. AN FAA INTERVIEW DISCLOSED THE INFORMATION THAT AN ATP RATED PILOT HAD GIVEN VERBAL PERMISSION TO THE STUDENT TO PERFORM THE SOLO FLIGHT. AT THE TIME OF THE ACCIDENT THE STUDENT AT THE CONTROLS HAD RECEIVED APPROXIMATELY 24 HOURS OF DUAL INSTRUCTION IN ROTORCRAFT OVER THE PREVIOUS 5 MONTHS. THE STUDENT PILOT'S CERTIFICATE HAD NOT BEEN ENDORSED FOR SOLO FLIGHT BY ANY INSTRUCTOR AT THE TIME OF THE ACCIDENT.
