## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - initial climb
  - engine assembly,valve,intake - incorrect (cause)
  - maintenance,installation - improper, other maintenance personnel (cause)
- In flight collision with object, takeoff - initial climb
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, takeoff - initial climb

## Analysis

THE ACFT COLLIDED WITH TREES AND THE GROUND AFTER THE ENGINE LOST POWER DURING TAKEOFF. THE CFI NOTED THE RPM DROPPING TO 2000 WITH FULL THROTTLE AND AT ABOUT 75 AGL AND TRIED TO ARREST THE DESCENT WITH FLAPS BUT WAS UNSUCCESSFUL. ONE TAKEOFF HAD BEEN ABORTED DUE TO POOR ACCELERATION BUT THE CFI HAD THOUGHT IT WAS IMPROPER THROTTLE TECHNIQUE ON THE PARTOF THE STUDENT. POST ACCIDENT ENGINE EXAMINATION REVEALED OLD TYPE VALVE SPRINGS INSTALLED THAT SHOULD HAVE BEEN REPLACED BY PN LW11800. A MECHANIC HAD INSTALLED NEW SPRINGS BUT OF AN INCORRECT TYPE WITH INCORRECT COLOR CODING. AVCO LYCOMING SERVICE INSTRUCTION 1240B CALLED FOR THE CHANGE TO IMPROVE ENGINE PERFORMANCE WITH THE RECOMMENDED IMPROVED VALVE SPRINGS.

## 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 19830808041999A](https://openairdocs.org/incident/19830808041999A), Aug 8, 1983: Piper PA28150, Brandon, FL, Destroyed. Aircraft crashed into trees off end of runway during takeoff. Engine reportedly lost power during takeoff.

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.
