## Probable cause

THE RUPTURE OF THE OIL COOLER LINE AT THE ADEL CLAMP FOR UNDETERMINED REASONS, RESULTING IN A LOSS OF ENGINE OIL, AND A SUBSEQUENT ENGINE SEIZURE.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, cruise - normal
  - lubricating system,oil line - failure,total (cause)
  - lubricating system,oil line - undetermined
  - fluid,oil - exhaustion
  - engine assembly - seized
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s)

## Analysis

THE PRIVATE PILOT WAS IN CRUISE FLIGHT IN VISUAL METEOROLOGICAL CONDITIONS AT 6,500 FEET MSL WHEN THE AIRPLANE EXPERIENCED A LOSS OF ENGINE OIL, AND A SUBSEQUENT ENGINE SEIZURE. THE PILOT CONTACTED DAYTONA APPROACH CONTROL, DECLARED AN EMERGENCY, AND CONDUCTED A FORCED LANDING INTO THE TREES. EXAMINATION OF THE ENGINE ASSEMBLY AND ACCESSORIES REVEALED THE OIL COOLER LINE AT THE ADEL CLAMP HAD FAILED FOR UNDETERMINED REASONS.
