## Probable cause

ENGINE FAILURE DUE TO IMPROPER OIL FILTER INSTALLATION AND SUBSEQUENT IMPROPER AIRCRAFT CONTROL BY THE PIC WHICH RESULTED IN A STALL. A FACTOR WAS MAINTENANCE INSPECTION NOT PERFORMED AFTER THE OIL FILTER INSTALLATION.

## Sequence of events

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

- Loss of engine power, climb - to cruise
  - lubricating system,oil filter/screen - improper (contributing factor)
  - maintenance,installation - performed, other person
  - maintenance,inspection - not performed, other person (contributing factor)
- Forced landing, descent - emergency
  - stall - inadvertent, pilot in command (cause)
- Fire, other

## Analysis

THE EVENING BEFORE THE FLIGHT THE OIL AND FILTER HAD BEEN CHANGED BY A PILOT WHO DID NOT PERFORM A MAINTENANCE ENGINE TEST RUN FOLLOWING THE WORK. A DIFFERENT PILOT DEPARTED IN THE AIRPLANE THE FOLLOWING MORNING AND A TOTAL ENGINE POWER LOSS OCCURRED. WITNESSES REPORTED THE AIRPLANE ENTERED A NOSE HIGH ATTITUDE AND THEN THE RIGHT WING HIT THE GROUND. THE AIRPLANE IMPACTED TO THE RIGHT OF THE RUNWAY AND EXPERIENCED A POST CRASH FIRE. EXAMINATION OF THE ENGINE AND ACCESSORIES REVEALED AN IMPROPER OIL FILTER INSTALLED.
