## 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 - high density altitude (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command
- In flight collision with object, descent - uncontrolled
  - object - utility pole (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Other investigations on N4772Y (1)

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.
