## Probable cause

The student pilot's failure to maintain control of the helicopter during landing, and the flight instructor's delayed remedial action.

## Sequence of events

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

- Loss of control - in flight, landing
  - aircraft control - not maintained, dual student (cause)
  - remedial action - delayed, pilot in command(cfi) (cause)
- Hard landing, landing
  - terrain condition - ground

## Analysis

The student pilot successfully performed three autorotations to a hover; however, during the fourth, he "landed hard with a yaw to the left."  The flight instructor was not able to correct the yaw, and the helicopter impacted the ground, damaging the tail boom.  The accident was not reported until the flight instructor was involved in a similar accident, in the same helicopter, about 30 days later.  No mechanical deficiencies were reported by the flight instructor or the student pilot.

## Other investigations on N2074K (1)

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.
