## NTSB investigations (3)

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.

- [NTSB CEN24LA372](https://openairdocs.org/ntsb/CEN24LA372), Sep 27, 2024: Piper PA-46-310P (N62VM), Eden Prairie, MN, substantial damage. Probable cause: The bird strike during cruise flight that resulted in substantial damage to the airplane.
- [NTSB CEN24LA286](https://openairdocs.org/ntsb/CEN24LA286), Jul 28, 2024: Piper PA46 (N4646G), Radisson, WI, substantial damage. Probable cause: The non-certificated mechanic’s failure to properly tighten and torque the fuel system pressure test port cap, which resulted in a total loss of engine power, and a subsequent forced landing.
- [NTSB ERA21LA087](https://openairdocs.org/ntsb/ERA21LA087), Dec 19, 2020: Piper PA46 (N662TC), Naples, FL, substantial damage. Probable cause: The inadvertent activation of the unguarded ferry tank fuel selector valve, which resulted in fuel starvation and a total loss of engine power.
