## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - loose objects
- Roll over, descent - uncontrolled

## Analysis

THE HELICOPTER CRASHED AFTER LOSING ROTOR RPM DURING A MAX PERFORMANCE TAKEOFF FROM A CONFINED AREA AT A PRIVATE LANDING AREA. THE PLT HAD ADDED 10 GALS OF FUEL AND HE WAS CARRYING A PASSENGER. THE PLT SAID HE AHD TAKEN OFF FROM THIS AREA BEFORE WITH NO PROBLEMS BUT HE DID NOT ELABORATE ON THE POSSIBLE DIFFERENCE IN LOAD FACTORS BETWEEN THIS & PREVIOUS FLTS.

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

- [Accident 19850428016119A](https://openairdocs.org/incident/19850428016119A), Apr 28, 1985: Bell 47H1, Guilford, VT, Destroyed. Aircraft could not clear trees in takeoff path. Made pedal turn, lost rotor RPM and struck trees.

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.
