## Probable cause

THE LOSS OF ENGINE POWER DUE TO THE INTAKE VALVE FAILURE.

## 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, climb - to cruise
  - engine assembly,valve,intake - failure,total (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - utility pole (contributing factor)

## Analysis

THE INSTRUCTOR AND STUDENT WERE ON A RETURN FLIGHT AFTER PRACTICING SOME COMMERCIAL MANEUVERS, WHEN THERE WAS A LOSS OF ENGINE POWER DURING THE CLIMB TO CRUISE FLIGHT.  ACCORDING TO THE INSTRUCTOR, WHEN THE LOSS OF POWER OCCURRED AT ABOUT 1200 FEET ABOVE THE GROUND, HE IMMEDIATELY TURNED THE AIRPLANE TO A 180 DEGREE HEADING AND COMPLETED THE EMERGENCY PROCEDURES.  HE STATED THAT HE ARRIVED OVER OCEAN PARKWAY AT 100 FEET MSL AND THE AIRPLANE STRUCK THE GROUND IN A LEFT WING LOW ATTITUDE. THE AIRPLANE STRUCK A TELEPHONE POLE BEFORE COMING TO REST ON THE WEST BOUND LANE OF OCEAN PARKWAY. AN EXAMINATION OF THE ENGINE BY THE FAA REVEALED ZERO COMPRESSION IN BOTH THE NUMBER 1 AND 2 CYLINDERS. FURTHER EXAMINATION OF THE CYLINDERS REVEALED FAILURE OF THE NUMBER 1 INTAKE VALVE TIP AND DAMAGE TO THE NUMBER 2 AND 4 CYLINDERS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
