## Sequence of events

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

- Loss of control - in flight, maneuvering
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command
- In flight collision with terrain/water, maneuvering

## Analysis

THE ACFT CRASHED IN THE WATER IN AN ISOLATED AREA OF THE FLORIDA BAY WHILE IN A NEAR INVERTED, LEFT WING LOW, NOSE DOWN ATTITUDE & AT A HIGH RATE OF DESCENT WITH SLOW FORWARD SPEED. THE LANDING GEAR WERE DOWN & LOCKED, & THE FLAPS WERE EXTENDED ABOUT 10 DEGS. EXAMINATION OF THE CARGO DOOR REVEALED EVIDENCE TO SUGGEST THAT IT WAS NOT HINGED TO THE ACFT DURING IMPACT. THE PURPOSE OF THE FLT IS STILL UNDER INVESTIGATION BY OTHER GOV'T AGENCIES.
