## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRSPEED ABOVE THE STALL SPEED DURING MANEUVERING FLIGHT.

## 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 - inadvertent, pilot in command
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT STATED THAT HE JUST FINISHED 'DRAGGING' A SAND BAR ON WHICH HE PLANNED TO LAND.  AFTER MAKING HIS PASS HE STARTED TO PULL UP AND MAKE A TURN.  HE STATED, DURING THE MANEUVER HE STALLED THE AIRPLANE.  THE AIRPLANE'S ALTITUDE DURING THE MANEUVER WAS 45 FEET ABOVE GROUND LEVEL.

## Factual narrative

On June 4, 1994, at 1500 Alaska daylight time, a wheel equipped Aeronca Champ, N84310, crashed while maneuvering after dragging a sand bar at approximately 45 ft. AGL.  The personal flight was conducted under 14 CFR 91 in visual meteorological conditions.  The flight departed from Anchorage, Lake Hood, and the destination was King Salmon, Alaska, with an intermediate stop at Driftriver Creek.  No flight plan was filed.  The pilot, the sole occupant, received minor injuries and the aircraft was substantially damaged.

According to the pilot, he was "dragging" the sandbar looking for a place to land when he pulled up to make a turn after his pass, stalled, and crashed.

## 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 19940604014009A](https://openairdocs.org/incident/19940604014009A), Jun 4, 1994: Bbavia 7AC, Naknet, AK, Substantial damage. Dragged a river sandbar to check for a landing. Stalled during go around on a turn out.

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.
