## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(.4)A FEW MINUTES AFTER TAKEOFF, THE PILOT REALIZED THE ENGINE WAS NOT DEVELOPING FULL MANIFOLD PRESSURE; SHORTLY THEREAFTER, THE ENGINE LOST ALL OIL PRESSURE. WHEN THE ENGINE BEGAN TO VIBRATE, THE PILOT SHUT DOWN THE ENGINE AND PERFORMED A FORCED LANDING TO A FIELD.  EXAMINATION OF THE AIRPLANE REVEALED THE ENGINE'S COWLING WAS COVERED WITH OIL, AND THE ENGINE'S CRANKSHAFT SEAL HAD BEEN 'BLOWN OUTWARD.' ICE WAS OBSERVED IN THE ENGINE CRANKCASE BREATHER LINE. ADDITIONALLY, A 'BEND' WAS FOUND IN THE BREATHER LINE NEAR A CLAMP THAT WAS INSTALLED OVER THE BREATHER LINE VENT HOLE.  THERE WERE NO OTHER DISCREPANCIES FOUND WITH AIRPLANE.  THE OUTSIDE AIR TEMPERATURE REPORTED AT THE AIRPORT ABOUT THE TIME OF THE ACCIDENT WAS 0 DEGREES F.  THE AIRPLANE WAS LAST FLOWN 1 WEEK PRIOR TO THE ACCIDENT.  THE AIRPLANE WAS KEPT IN AN UNHEATED HANGER; HOWEVER, THE ENGINE WAS PREHEATED USING A BUILT-IN ENGINE HEATER TO AN OIL TEMPERATURE OF 40 DEGREES F, JUST PRIOR TO ENGINE START.                                                                        (-23)NYC00LA069

## The NTSB's investigation of this event (1)

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.

- [NTSB NYC00LA069](https://openairdocs.org/ntsb/NYC00LA069), Jan 21, 2000: Mooney M20M (N223KT), Montpelier, VT, substantial damage. Probable cause: A blocked crankcase breather line due to ice and improper maintenance which resulted in further restricting the line. A factor in this accident was the below freezing outside air temperature.
