What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On may 30, 2019, at 1330 EST a 1981 Piper, model Aerostar-600, N36387 that is registered to privacy data omitted departed Venice municipal airport Venice, Florida on a CFR part 91 flight. The pilot was on climb-out and the upper hatch door departed the aircraft. The door did not strike the aircraft and the aircraft did not sustain any damage. The pilot stated the door safe condition indicator was in the safe condition prior to take off but the indicator then moved to the unsafe condition while on climb-out. The pilot attempted to relatch the d-handle on the door but was unsuccessful and the door opened and blew off the aircraft. Maintenance personnel could not find a defect with the aircraft door attach points and the door itself was never recovered. Visual meteorological conditions prevailed at the time and an IFR flight plan was not filed. The passengers were not injuried.
