## Probable cause

THE DELAYED REMEDIAL ACTION OF THE PILOT (CFI). FACTORS INCLUDE LACK OF TOTAL EXPERIENCE IN TYPE OF AIRCRAFT, AND LACK OF TOTAL EXPERIENCE IN TYPE OF OPERATION.

## Sequence of events

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

- Loss of control - in flight, hover
  - remedial action - delayed, pilot in command(cfi) (cause)
  - lack of total experience in type of aircraft, pilot in command(cfi) (contributing factor)
  - lack of total experience in type operation, pilot in command(cfi) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE STUDENT PILOT OF THE BRANTLY-HYNES B-2B INITIATED A RIGHT PEDAL-TURN WHILE IN THE HOVER, BUT WAS UNABLE TO STOP THE ROTATION. WHEN THE CERTIFIED FLIGHT INSTRUCTOR TOOK CONTROL OF THE AIRCRAFT, HE FOUND THAT HE WAS ALSO UNABLE TO STOP THE ROTATION WITH FULL PEDAL DEFLECTION. HE THEREFORE ELECTED TO ATTEMPT AN AUTOROTATIONAL LANDING, BUT DURING THIS ATTEMPT, THE AIRCRAFT ROLLED OVER AND IMPACTED THE GROUND.
