## Probable cause

THE PARTIAL POWER LOSS DUE TO CYLINDER FATIGUE AND RESULTANT ENGINE VIBRATIONS. FACTORS WERE THE OIL COVERED WINDSHIELD RESTRICTING THE PILOT'S VISION AND THE WET TERRAIN.

## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, cruise - normal
  - engine assembly - vibration (cause)
  - engine assembly,cylinder - fatigue (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing
  - fluid,oil - leak
  - window,flight compartment window/windshield - dirty(foggy) (contributing factor)
  - visual lookout - restricted, pilot in command (contributing factor)
  - terrain condition - none suitable
  - terrain condition - wet (contributing factor)
- Nose over, landing - roll

## Analysis

AT 12,000 FEET AGL THE PILOT EXPERIENCED SEVERE ENGINE VIBRATIONS AND OIL WAS OBSERVED ESCAPING FROM THE ENGINE COWLING ONTO THE WINDSHIELD. ATC INITIALLY GAVE VECTORS FOR LANDING AT AN AIRPORT ABOUT 18 MILES AWAY. OIL ON THE WINDSHIELD OBSCURED VISIBILITY AND ENGINE VIBRATIONS WORSENED AND THE PILOT ELECTED TO PERFORM A FORCED LANDING OFF AIRPORT. DURING THE LANDING ROLL ON WET PLOWED TERRAIN THE AIRPLANE NOSED OVER. FOUR OF THE NUMBER TWO CYLINDER STUDS EXHIBITED MULTI-ORIGIN FATIGUE AT THE FRACTURE SURFACE DUE TO IMPROPER STRETCH OR TORQUE ON THE STUDS.

## FAA reports on this event (1)

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

- [Accident 19920114000569A](https://openairdocs.org/incident/19920114000569A), Jan 14, 1992: Cessna 2105A, Spring, TX, Substantial damage. Lost power. Oil on windshield. Nosed over on off airport landing. Cylinder studs broke in fatigue from over torque.

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.
