## Probable cause

WATER CONTAMINATION INTRODUCED INTO THE AIRPLANE FUEL SYSTEM WHEN THE AIRPLANE WAS WASHED. CONTRIBUTING TO THE ACCIDENT WAS AN 18 KNOT TAILWIND DURING LANDING ROLL WHICH RESULTED IN THE AIRPLANE OVERRUNNING THE RUNWAY.

## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - fluid,fuel - contamination (cause)
  - maintenance,service of aircraft/equipment - performed, pilot in command (contributing factor)
- Overrun, landing - roll
  - weather condition - tailwind (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - object - other
- Nose over, landing - roll

## Analysis

THE PLT INDICATED THE ENG LOST POWER AND CONTINUED TO IDLE AT 400 FT AGL WHILE IN A RIGHT TURN. THE PLT LANDED THE AIRPLANE ON THE TAKEOFF RWY IN THE REVERSE DIRECTION. THE AIRPLANE OVERRAN THE RWY, AND STRUCK AN IRRIGATION PIPE. THE AIRPLANE NOSED OVER. AN 18 KNOT TAILWIND WAS REPORTED AT THE TIME OF THE ACCIDENT. THE AIRPLANE HAD A LOSS OF ENG POWER IN AUGUST OF 1989. THERE WERE NO INJURIES OR DAMAGE TO THE AIRPLANE AS A RESULT OF THE INCIDENT. THE ENG WAS EXAMINED AS A RESULT OF THE INCIDENT. THERE WAS NO EVIDENCE OF A MECHANICAL FAILURE OR MALFUNCTION FOUND. THE AIRPLANE HAD BEEN FLOWN ONCE FOR ABOUT AN HOUR SINCE AGU 1989. AFTER THE ACCIDENT THE ENG WAS AGAIN EXAMINED. THERE WAS NO EVIDENCE OF MECHANICAL FAILURE. THE ENG STARTED AND RAN FOR 30 MIN AFTER THE ACCIDENT. THE PLT INDICATED THAT THE AIRPLANE HAD BEEN WASHED BEFORE THE AUGUST 1989 INCIDENT. IT WAS REPORTED THAT THE AIRPLANE WAS AGAIN WASHED BEFORE THE ACCIDENT.

## 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 19900505063619A](https://openairdocs.org/incident/19900505063619A), May 5, 1990: Mooney M20E, Torrance, CA, Substantial damage. Engine quit on climbout. Made 180 but overshot runway downwind.

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.
