## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - iaf to faf/outer marker (ifr)
  - fluid,fuel - starvation
  - fuel tank selector position - improper, pilot in command (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

PRIOR TO REACHING THE LOM DURING AN ILS RWY 01L APCH, A LOSS OF PWR WAS EXPERIENCED. THE PLT APPLIED CARB HEAT AND PWR WAS MOMENTARILY RESTORED. A TOTAL PWR LOSS WAS THEN EXPERIENCED AND THE PLT EXECUTED A FORCED LANDING IN A FIELD DURING WHICH THE ACFT NOSED OVER. POST ACCIDENT INSPECTION REVEALED THE FUEL SELECTOR WAS POSITIONED ON THE LEFT TANK WHICH CONTAINED NO FUEL. THE PLT REPORTED HE HAD FAILED TO CHANGE FUEL TANKS AFTER THE ENG FAILURE.

## 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 19860624027359A](https://openairdocs.org/incident/19860624027359A), Jun 24, 1986: Gulstm AA1B, Camp Springs, MD, Destroyed. Distracted from switching fuel tanks because of weather. Ran tank dry on ILS approach. Hit trees on forced landing.

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.
