## Sequence of events

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

- Abrupt maneuver, takeoff - initial climb
  - aircraft handling - improper, pilot in command(cfi) (cause)
  - proper altitude - not attained, pilot in command(cfi) (cause)
  - crew/group coordination - inadequate, pilot in command(cfi) (cause)
  - interpretation of instructions - not understood, dual student (cause)
  - stall - uncontrolled, dual student (cause)
- Loss of control - in flight, maneuvering - turn to reverse direction
  - supervision - inadequate, pilot in command(cfi) (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - snow covered (contributing factor)
  - altitude - inadequate (contributing factor)
  - pull-up - not possible, pilot in command(cfi) (cause)

## Analysis

A PRE-SOLO STUDENT AND CFI WERE PRACTICING LANDINGS. THE CFI REDUCED PWR ON CLIMBOUT AT 300 TO 400 FEET. DURING THE DISCUSSION OF WHAT TO DO IN CASE OF LOST PWR ON TAKEOFF, THE STUDENT EXECUTED A STEEP, 180 DEGREE TURN, TOWARD THE ARPT. THE ACFT STALLED, AND THE CFI TOOK CONTROL, UNABLE TO RECOVER PRIOR TO GROUND IMPACT. THE ACFT NOSED OVER AT IMPACT.

## 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 19870327007699A](https://openairdocs.org/incident/19870327007699A), Mar 27, 1987: Bbavia 7AC, Columbus, MT, Destroyed. The student made a steep turn during a simulated engine loss on takeoff. The aircraft stalled into a wheat field.

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.
