## Probable cause

THE PILOTS'DECISION TO FLY INTO MARGINAL VFR WEATHER. A FACTOR WAS THE GUY WIRE AND FOG.

## Sequence of events

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

- In flight collision with object, maneuvering - turn to reverse direction
  - object - guy wire (contributing factor)
  - flight into known adverse weather - performed, pilot in command (cause)
  - weather condition - fog (contributing factor)
- Loss of control - in flight, descent - uncontrolled
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

A NON INSTRUMENT RATED PILOT DEPARTED FOR CROSS COUNTRY FLIGHT WITHOUT A PREFLIGHT WEATHER BRIEFING. SHORTLY AFTER DEPARTURE THE PILOT REPORTED THAT HE ENCOUNTERED A LOWERING CEILING AND INITIATED A 180 DEGREE RIGHT TURN. RESTRICTED VISIBILITY DUE TO FOG WAS REPORTED IN THE AREA. THE PILOT STATED THAT HE SAW THE GUY WIRE JUST PRIOR TO THE IMPACT. THE AIRPLANE DESCENDED UNCONTROLLED TO THE TERRAIN.

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.
