## Probable cause

THE PILOT IN COMMAND'S FAILURE TO MAINTAIN AIRSPEED DURING AN ABORTED LANDING RESULTING IN AN INADVERTENT STALL AND DESCENT INTO TREES.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - improper, pilot in command (contributing factor)
  - lack of total experience, pilot in command (contributing factor)
- Loss of control - in flight, landing - aborted
  - airspeed - not maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s) (contributing factor)

## Analysis

THE PRIVATE PILOT WAS IN THE TRAFFIC PATTERN. ON FINAL TO RUNWAY 18, WITH 30 DEGREES OF FLAPS, THE AIRPLANE DRIFTED LEFT OF CENTERLINE AND THE PILOT EXECUTED A GO AROUND. HE SAID HE ADDED FULL POWER, AND RAISED THE FLAPS TO 20 DEGREES. HE CONTINUED A LEFT DRIFT TOWARD TREES IN A NOSE HIGH, LOW AIRSPEED CONDITION. THE PILOT INCREASED THE PITCH AND ADDED 10 DEGREES OF FLAPS TO CLEAR THE TREES. THE AIRPLANE STALLED AND STRUCK THE TREES IN A NOSE DOWN ATTITUDE. THE FAA REPORTED THERE ARE TREES ON BOTH SIDES OF THE RUNWAY AND THE WINDS AS 090 DEGREES AT 10 KTS, GUSTS TO 20 KTS, VARIABLE TO 060 DEGREES AT 14 KTS.
