## Sequence of events

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

- Loss of control - on ground/water, takeoff
  - emergency procedure - simulated, pilot in command(cfi) (contributing factor)
  - weather condition - gusts (contributing factor)
  - compensation for wind conditions - improper, pilot in command(cfi) (cause)
  - directional control - not maintained, pilot in command(cfi) (cause)
  - ground loop/swerve - uncontrolled
- Gear collapsed, takeoff - aborted
  - terrain condition - soft (contributing factor)
  - landing gear - overload

## Analysis

DURING A DEMONSTRATION OF AN ABORTED TAKEOFF, THE 'POWER WAS CUT' AFTER THE AIRCRAFT ACCELERATED TO ABOUT 75 MPH. AT ABOUT THAT TIME, THE AIRCRAFT ENCOUNTERED A GUST OF WIND AND BECAME AIRBORNE. A POWER RECOVERY WAS INITIATED, BUT THE AIRCRAFT TOUCHED DOWN IN A YAW. SUBSEQUENTLY, IT SLID SIDEWAYS UNTIL CONTACTING SOFT DIRT BESIDE THE RUNWAY, THEN THE MAIN GEAR COLLAPSED AND THE NOSE GEAR, RIGHT WING AND PROPS WERE DAMAGED.

## 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 19870720047399A](https://openairdocs.org/incident/19870720047399A), Jul 20, 1987: Piper PA30, Bad Axe, MI, Substantial damage. Swerved off the runway and collapsed the landing gear when CFI gave the multiengine student a simulated engine 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.
