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. - [NTSB FTW94FA300](https://openairdocs.org/ntsb/FTW94FA300), Sep 18, 1994: Piper PA-24-260 (N9159P), Tennesse Colony, TX, substantial damage, 2 fatal. Probable cause: THE PILOT'S FAILURE TO MAINTAIN AIRSPEED AND THE RESULTANT INADVERTENT STALL/SPIN. A FACTOR WAS THE LOSS OF ENGINE POWER FOR UNDETERMINED REASONS. - [NTSB MKC76FCD55](https://openairdocs.org/ntsb/MKC76FCD55), Jul 4, 1976: Acroduster 1 (N91FF), Council Bluffs, IA, destroyed, 1 fatal --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
