## Probable cause

FAILURE OF THE PILOT TO MAINTAIN AN AIRSPEED ABOVE STALLING SPEED WHILE TURNING FROM BASE LEG TO FINAL APPROACH. FACTORS IN THE ACCIDENT ARE THE PILOT'S LACK OF TOTAL AND RECENT AVIATION EXPERIENCE.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - base leg/base to final
  - airspeed(vs) - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - lack of recent experience, pilot in command (contributing factor)
- In flight collision with object, descent - uncontrolled
  - object - fence

## Analysis

THE ACCIDENT AIRPLANE COLLIDED WITH A FENCE DURING AN OUT OF CONTROL DESCENT.  THE PILOT HAD OVERSHOT THE TURN TO FINAL AND WAS PERFORMING A 360 DEGREE TURN TO ALIGN HIMSELF WITH THE RUNWAY WHEN HE REALIZED HIS BANK ANGLE WAS BECOMING STEEPER.  HIS ONLY CLEAR MEMORY AFTER THAT WAS CLIMBING OUT OF THE AIRPLANE AFTER IMPACT.

## 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.
