## Probable cause

THE PILOT IN COMMAND/INSTRUCTOR PILOT FAILED TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE DURING THE GROUND RUN.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)
- Main gear collapsed, takeoff - roll/run
  - landing gear - overload
  - design stress limits of aircraft - exceeded, pilot in command (contributing factor)

## Analysis

ACCORDING TO THE INSTRUCTOR AND THE PRIVATE PILOT, JUST AFTER TAKEOFF POWER WAS ADDED, THE AIRPLANE VEERED TO THE RIGHT.  THE LEFT MAIN LANDING GEAR THEN COLLAPSED AND THE LEFT WING HIT THE GROUND.  BOTH PILOTS WERE ON THE CONTROLS AT THE TIME.  BOTH ALSO SAID THEY WERE IN A HURRY TO TAKEOFF SINCE AN AIRLINE JET WAS WAITING DEPARTURE FROM THE SAME RUNWAY.

## 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 19920806029579A](https://openairdocs.org/incident/19920806029579A), Aug 6, 1992: Cessna A185F, Ketchikan, AK, Substantial damage. Lost directional control on initial takeoff roll. Apparently over compensated for torque and p factor. CFI error.

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.
