## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL WHICH RESULTED IN A NOSE OVER DURING THE PRECAUTIONARY LANDING. RELATED FACTORS ARE THE POWER LINES (OBSTRUCTIONS) AND INADEQUATE ALTITUDE.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - object - wire,transmission (contributing factor)
  - altitude - inadequate, pilot in command (contributing factor)
  - precautionary landing - performed, pilot in command
  - aircraft control - not maintained, pilot in command (cause)
- Nose over, landing - roll

## Analysis

THE PILOT REPORTED HE WAS TAKING OFF WITH A LOAD OF CHEMICALS FOR AERIAL APPLICATION.  HE STATED THE AIRPLANE '...LIFTED OFF THE RUNWAY, BUT AT A SLOW SPEED.  I REMAINED CLOSE TO THE GROUND TO STAY IN GROUND EFFECT, BUT NOTICED NO ACCELERATION.'  THE PILOT DETERMINED THE AIRPLANE WOULD NOT CLEAR THE POWER LINES LOCATED OFF THE DEPARTURE END OF THE RUNWAY, SO HE ABORTED THE TAKEOFF.  THE AIRPLANE NOSED OVER JUST AFTER IT TOUCHED DOWN, AND SKIDDED ABOUT 20 FEET BEFORE IT CAME TO A STOP.

## 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 19920429012189A](https://openairdocs.org/incident/19920429012189A), Apr 29, 1992: Scwzer G164B, Scotia, NE, Substantial damage. Aircraft failed to accelerate in ground effect after rolling through soft spot. Aborted. Plane flipped over on back

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.
