## Sequence of events

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

- Loss of engine power, approach - vfr pattern - base turn
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch
- On ground/water collision with object, landing - roll
  - object - tree(s)

## Analysis

FOR UNDETERMINED REASONS THE PLT EXPERIENCED A POWER LOSS ON BOTH LEFT ENGINES WHILE TURNING FROM LEFT BASE TO FINAL FOR LDG. THE PLT WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL AND ELECTED TO REDUCE POWER ON THE RIGHT ENGINES. DURING THE FORCED LDG ROLL THE ACFT COLLIDED WITH 3 DITCHES AS WELL AS SMALL TREES. AS THE ACFT TOUCHED DOWN BOTH LEFT ENGINES RESUMED FULL POWER.

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

- [Accident 19840405012539A](https://openairdocs.org/incident/19840405012539A), Apr 5, 1984: Hwksly DH1142X, Scottsdale, AZ, Substantial damage. Both left engines quit on final. Asmetrical thrust caused forced landing. Impacted trees and ditches.

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.
