## NTSB investigations

None matched to N401PH.

## NTSB investigations on N401PH not matched to an aircraft (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.

- [NTSB FTW93FA163](https://openairdocs.org/ntsb/FTW93FA163), May 25, 1993: MBB BK 117 A-4 (N401PH), Lafayette, LA, substantial damage. Probable cause: CYCLIC CONTROL ROD MOVEMENT WAS RESTRICTED DUE TO IMPROPER INSTALLATION OF THE LATERAL CYCLIC CONTROL ROD BY COMPANY MAINTENANCE PERSONNEL.

## FAA accident and incident reports
