## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, approach - vfr pattern - final approach
  - weather condition - carburetor icing conditions (contributing factor)
  - fuel system,carburetor - ice (cause)
  - throttle/power control - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s) (contributing factor)

## Analysis

THE PLT REPORTED THAT THE ACFT WAS NO. 3 IN THE PATTERN FOR LANDING ON RWY 17. HE SAID CARB HEAT WAS APPLIED ON DOWNWIND AND ENG POWER WAS USED UNTIL THE ACFT WAS ON A 3 MI FINAL. AT THAT POINT PWR WAS REDUCED AND A GLIDE WAS ESTABLISHED. A SHORT TIME LATER THE PLT ADVANCED THE THROTTLE TO ADJUST THE GLIDE AND THE ENG WOULD NOT ACCELERATE ABOVE IDLE. THE TEMP/DEW PT AT AN AIRPORT 10 MI N OF THE ACDT SITE WAS 55 DEG F AND 29 DEG F RESPECTIVELY. THE ACFT WAS REBUILT AND THE ENG WAS RUN AT THE CONCLUSION OF THE REBUILD PROJECT ON 1/14/89. THE ENG RAN NORMALLY AND NO EVIDENCE OF A MECHANICAL CAUSE FOR THE LOSS OF PWR WAS FOUND.

## 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 19871111076199A](https://openairdocs.org/incident/19871111076199A), Nov 11, 1987: Piper PA18150, Dallas, TX, Substantial damage. Engine failed to respond on long final. Struck trees and rocks short of runway. Engine ran normal post accident.

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.
