## Probable cause

THE PILOT'S IMPROPER APPLICATION OF TAKEOFF POWER WHICH RESULTED IN A LENGTHENED TAKEOFF ROLL, AND HIS SUBSEQUENT STEEP TURN TO AVOID AN OBSTACLE CAUSING THE AIRPLANE TO STALL AT A LOW ALTITUDE.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - throttle/power control - delayed, pilot in command (cause)
  - altitude - not attained, pilot in command (cause)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

THE AGRICULTURAL AIRPLANE ATTEMPTED A TAKEOFF FROM THE GRASS RUNWAY, BUT THE PILOT WAS UNABLE TO ATTAIN SUFFICIENT ALTITUDE TO CLEAR WIRES AT THE END OF THE RUNWAY.  THE PILOT TURNED THE AIRPLANE AND WAS UNABLE TO MAINTAIN AIRSPEED AND THE AIRPLANE STALLED.  THE AIRPLANE WAS WITHIN 24 POUNDS OF THE MAXIMUM ALLOWABLE GROSS WEIGHT.  THE TEMPERATURE WAS REPORTED AS 90 DEGREES F AND THE WINDS WERE LIGHT.  A WITNESS SAID, 'THE POWER WAS NOT AT TAKEOFF DURING THE ROLL. IT APPEARED AS IF (THE PILOT) APPLIED POWER TOO GRADUALLY. AFTER TAKEOFF, HE MADE A SHARP RIGHT TURN TO AVOID THE WIRES.'

## 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 19920608053759A](https://openairdocs.org/incident/19920608053759A), Jun 8, 1992: Scwzer G164A, Bridgeton, NJ, Substantial damage. Lifted near end of runway,banked sharply to avoid wires and stalled. Factors near gross weight hot calm day.

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.
