## Sequence of events

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

- Loss of control - in flight, maneuvering - turn to reverse direction
  - weather condition - windshear (cause)
  - inadequate training, pilot in command(cfi) (cause)
  - airspeed - misjudged, copilot/second pilot (contributing factor)
  - stall - inadvertent, copilot/second pilot (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PIC REPORTED THE 2ND PLT WAS FLYING THE ACFT AT THE TIME OF THE ACCIDENT WHILE THEY WERE PRACTICING OFF ARPT LANDINGS. ON THE SECOND TAKEOFF, THE 2ND PLT EXECUTED A COURSE REVERSAL TURN TO LAND OPPOSITE THE DIRECTION OF TAKEOFF. THE INITIAL TURN WAS TO THE LEFT. AFTER COMLETING THE 90 DEG LEFT TURN AND WHILE IN THE 270 DEG RIGHT TURN THE ACFT RIGHT WING BANKED 90 DEGREES AND THE NOSE DROPPED 70 DEGREES. CONTROL INPUTS WOULD NOT ARREST THE ACFT ATTITUDE. PRIOR TO IMPACT THE PIC RETARDED THE THROTTLE TO IDLE. LIGHT VARIABLE SURFACE WINDS PREVAILED. THE PIC REPORTED A 30 DEG TEMP INVERSION AT ALTITUDE WAS EXPERIENCED.

## 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 19850107001249A](https://openairdocs.org/incident/19850107001249A), Jan 7, 1985: Bbavia 7AC, Chandler, AZ, Substantial damage. Wing dropped during turn in pattern. Nose fell through and plane struck ground. Temp inversion, probable windshear.

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.
