## Probable cause

AN INADVERTENT STALL/SPIN.  FACTORS RELATED TO THE ACCIDENT WERE AN IMPROPERLY PLANNED APPROACH BY THE PILOT, THE FAILURE OF THE PILOT TO ATTAIN AND MAINTAIN FLYING SPEED, RISING TERRAIN, AND TURBULENT AIR CONDITIONS.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - terrain condition - rising (contributing factor)
  - planned approach - improper, pilot in command (cause)
  - airspeed - not maintained, pilot in command (cause)
  - stall/spin - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT MISREAD THE TERRAIN AND INITIATED AN APPROACH TO RISING TERRAIN. HE MADE A GO AROUND AND WAS UNABLE TO LOWER THE NOSE ENOUGH TO ACCELERATE.  DURING THE GO AROUND, THE AIRPLANE ENTERED A STALL/SPIN.  IN ADDITION, THE WINDS WERE GUSTY AND THE AIRPLANE WAS FLYING THROUGH TURBULENT AIR.

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.
