## Probable cause

FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED, RESULTING IN AN INADVERTENT STALL AND SUBSEQUENT LOSS OF CONTROL. A RELATED FACTOR WAS: THE LACK OF A STALL WARNING SYSTEM INSTALLED IN THE AIRCRAFT.

## Sequence of events

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

- Loss of control - in flight, maneuvering
  - airspeed(vs) - not maintained, pilot in command (cause)
  - stall warning system - not installed (contributing factor)
  - stall/spin - inadvertent, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

DURING A CROSS COUNTRY FLIGHT, THE PILOT CIRCLED HIS RESIDENCE WHICH WAS LOCATED NEAR THE DESTINATION AIRPORT. WHILE MANEUVERING, THE PILOT LOST CONTROL, AND THE AIRCRAFT DESCENDED INTO A WOODED AREA. THE AIRCRAFT DID NOT CONTAIN A STALL WARNING SYSTEM.

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.
