## Probable cause

THE PILOT'S PERFORMANCE OF AN AEROBATIC MANEUVER AT AN ALTITUDE INADEQUATE TO ALLOW FOR SAFE RECOVERY.

## Sequence of events

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

- In flight collision with terrain/water, maneuvering
  - aerobatics - performed, pilot in command
  - altitude - inadequate, pilot in command (cause)

## Analysis

THE PILOT HAD BEEN PERFORMANING AEROBATIC MANEUVERS OVER THE CITY AND INITIATED A LOOP AT LOW ATITUDE.  AT THE BOTTM OF THE LOOP, ON  A NORTHERLY HEADING, THE AIRPLANE BANKED SHARLPY TO THE LEFT AND IMPACTED THE GROUND.  ELECTRICAL POWER LINES RAN IN AN EAST-WEST DIRECTION A SHORT DISTANCE NORTH OF THE POINT OF IMPACT.  WITNESS STATEMENTS WERE CONTRADICTORY REFERENCE WHETHER THE MANEUVER WAS AN OUTSIDE OR INSIDE LOOP.

## 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 19910704025789A](https://openairdocs.org/incident/19910704025789A), Jul 4, 1991: Amtrbb MUSTANGMIDGT, Santa Fe, TX, Destroyed, 1 fatal. Collided with ground at bottom of loop. Had been performing aerobatics at low altitude near residential area.

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.
