## Probable cause

AN INFLIGHT BREAKUP AFTER THE PILOT ENCOUNTERED WEATHER, LOST CONTROL INFLIGHT, & EXCEEDED THE DESIGN LIMITS OF THE AIRPLANE. A FACTOR WAS THE PILOT'S DECISION TO FLY INTO KNOWN ADVERSE WEATHER.

## Sequence of events

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

- In flight encounter with weather, cruise
  - weather condition - fog
  - flight into known adverse weather - initiated, pilot in command (contributing factor)
- Loss of control - in flight, cruise
  - design stress limits of aircraft - exceeded, pilot in command (cause)
  - aircraft control - not maintained, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT OF THE ACCIDENT AIRPLANE WAS OBSERVED FLYING IN AN AREA OF FOG AND LOW VISIBILITY.  THE AIRPLANE BROKE APART IN FLIGHT.  BOTH WINGS WERE FOUND A QUARTER OF A MILE FROM THE FUSELAGE ABOUT 100 YARDS APART.  A WITNESS WHO SAW THE AIRPLANE TAKEOFF REPORTED THAT HE LOST SIGHT OF THE AIRPLANE IN FOG BEFORE IT REACHED THE AIRPORT BOUNDARY.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19910404008909A](https://openairdocs.org/incident/19910404008909A), Apr 4, 1991: Amtr STINGER, Blairstown, MO, Destroyed, 1 fatal. Lost control on climbout into fog. Spiral dive. Pullup. Airframe failure.

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.
