NTSB narrative
THE PLT WAS ON A X-COUNTRY FLT WHEN HE NOTICED THE OIL PRESSURE WAS DECREASING RAPIDLY. HE ELECTED TO MAKE AN OFF-AIRPORT LANDING, BUT THE ENGINE SEIZED BEFORE HE COULD REACH THE SELECTED AREA. SUBSEQUENTLY, THE AIRCRAFT WAS DAMAGED DURING A WHEELS UP LANDING. INITIAL TOUCHDOWN WAS ON A GRAVEL ROAD AND THE ACFT HIT A BERM BEFORE SLOWING TO A STOP. AN EXAM OF THE AIRCRAFT AND ENGINE REVEALED AN OIL (QUICK) DRAIN VALVE (AEROQUIP PN: AE80664H) HAD BEEN INSTALLED ON 7/10/87. IT WAS INSTALLED WITH A 4-3/8 INCH HOSE THAT EXTENDED BELOW THE ENGINE RESERVOIR, IN THE VICINITY OF THE LANDING GEAR. SUBSEQUENTLY, THE DRAIN VALVE WAS PUSHED OPEN BY MOVEMENT OF THE LANDING GEAR AS IT WAS BEING RETRACTED. THIS RESULTED IN LOSS OF OIL & SUBSEQUENT ENGINE SEIZURE. THIS DRAIN VALVE WAS NOT APPROVED FOR INSTALLATION ON THIS MODEL OF AIRCRAFT. PIPER SERVICE LETTER 910 & AD 81-11-02/R1 SPECIFIED USE OF ANOTHER VALVE (PIPER PN: 492-172V).
Probable cause
INSTALLATION OF AN IMPROPER OIL DRAIN VALVE BY OTHER MAINTENANCE PERSONNEL AND THEIR FAILURE TO FOLLOW THE APPLICABLE AIRWORTHINESS DIRECTIVE (AD 81-11-02/R1), RESULTING IN SUBSEQUENT INTERFERENCE BETWEEN THE LANDING GEAR AND OIL DRAIN VALVE. THIS CAUSED THE VALVE TO MOVE OPEN & LEAK, WHICH RESULTED IN THE LOSS OF ALL ENGINE OIL.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
