## Probable cause

ENGINE POWER LOSS WHILE LANDING DUE TO FUEL EXHAUSTION.

## Sequence of events

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

- Loss of engine power, landing
  - fluid,fuel - exhaustion
  - planning/decision - inadequate, pilot in command (cause)
- Loss of control - in flight, descent - emergency
  - aircraft handling - not maintained, pilot in command (cause)
- Roll over, landing

## Analysis

AFTER THE INSTRUCTOR PILOT TOOK CONTROL OF THE HELICOPTER FOR A LANDING, THE HELICOPTER LOST POWER. THE PILOT AUTOROTATED TO A HARD LANDING AND THE HELICOPTER ROLLED OVER ONTO ITS RIGHT SIDE. A POST ACCIDENT EXAMINATION OF THE ENGINE DID NOT REVEAL ANY MECHANICAL DISCREPANCIES, HOWEVER ONLY 3/10TH OF A GALLON OF FUEL WAS FOUND IN THE FUEL SYSTEM. THE FUEL CAPACITY IS 19.8 GALLONS OF WHICH 19.2 GALLONS IS USEABLE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19881129071559A](https://openairdocs.org/incident/19881129071559A), Nov 29, 1988: Robsin R22, Norwood, MA, Substantial damage. Ran out of fuel on a dual instruction flight. Autorotated into a cemetery. Low rotor speed resulted in hard impact

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.
