## 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
  - engine assembly,cylinder - low compression (contributing factor)
  - precautionary landing - simulated, pilot in command(cfi) (cause)
  - ignition system,spark plug - dirty(foggy) (contributing factor)
  - throttle/power control - improper use of, pilot in command(cfi) (cause)

- In flight collision with object, approach - vfr pattern - final approach
  - object - wire,static (contributing factor)
- Nose over, landing - roll
  - landing gear,nose gear - overload (contributing factor)

## Analysis

THE ACFT COLLIDED WITH A POWER LINE AND NOSED OVER DURING AN ATTEMPT TO RECOVER FROM A SIMULATED FORCED LANDING. THE CFIREPORTEDLY 'CLEARED' THE ENGINE DURING THE APPROACH BUT WHEN SHE TOOK OVER AND ADDED POWER TO CLIMB SHE CLAIMED THE ENGINE DID NOT FULLY RESPOND. SHE WAS UNABLE TO CLEAR A POWER LINE, WHICH HAD REMAINED UNSEEN ON THE APPROACH, AND THE POWERLINES SLIGHT CONTACT WITH THE LANDING GEAR 'TRIPPED' THE ACFT INTO A 'HEAVY' LANDING WHICH COLLAPSED THE NOSE GEAR AND THE ACFT NOSED OVER. THE ACFT ENGINE HAD JUST BEEN ADJUSTED TO A LOWER IDLE SPEED PRIOR TO THIS FLT PER THE CFIS REQUEST. THE MECHANIC SAID THE ENGINE WAS 'WARM' DURING THE IDLE ADJUSTMENT. DURING POST ACCIDENT EXAM THE COMPRESSION ON CYLINDERS #1 & #4 WAS VERY WEAK AND THEY WERE STAKED TO GET AN IMPROVEMENT. THE LOWER PLUGS WERE NOTED TO BE COATED WITH BLACK OIL. THE MAGS CHECKED AS NORMAL.

## 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 19840810039939A](https://openairdocs.org/incident/19840810039939A), Aug 10, 1984: Cessna 150J, Justin, TX, Destroyed. Pilot stated that engine hesitated when throttle was applied after simulated emergency. Auto fuel being used.

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.
