## The NTSB's investigation of this event (1)

- [NTSB FTW95FA394](https://openairdocs.org/ntsb/FTW95FA394), Sep 14, 1995: MBB BO-105C (N650MS), Houston, TX, destroyed. Probable cause: the failure of the main transmission's #1 (left) input pinion assembly, due to the partially blocked oil passage which reduced oil flow, resulting in the disconnect of the drive shaft.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong.
