## Sequence of events

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

- Undershoot, approach - vfr pattern - final approach
  - lowering of flaps - not identified, pilot in command (contributing factor)
  - proper descent rate - not maintained, pilot in command (cause)
- In flight collision with object, approach - vfr pattern - final approach
  - object - tree(s) (contributing factor)

## Analysis

THE PLT STATED HE ADDED 10 DEGREES OF FLAPS ON DOWNWIND AND APPLIED FULL FLAPS ON FINAL. A RAPID RATE OF DESCENT WAS EXPERIENCED 200 YARDS FROM TOUCHDOWN. THE PILOT SAID HE ADDED POWER TO ARREST THE SINK RATE. THE ACFT COLLIDED WITH TREES ON FINAL. THE PILOT STATED THAT AFTER THE ACCIDENT, THE FLAPS WERE EXTENDED 10 DEGREES, THE FLAP ACTUATOR HANDLE WAS IN THE FULL DOWN POSITION AND THE FLAP CIRCUIT BREAKER WAS OUT. A MECHANIC WHO INSPECTED THE ACFT AFTER THE ACCIDENT REPORTED NO MECHANICAL ABNORMALITIES WERE FOUND.

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.
