Safety record

Accident & incident history

2018-07-29 Accident · Bettles, AK Damage: Substantial NTSB · ANC18LA058
Reported aircraft: Robinson R44
Probable cause: Maintenance personnel's application of insufficient preload on the attachment hardware for the idler gear shaft during engine overhaul, which resulted in the dismounting of the idler gear shaft assembly due to wear and deformation and the subsequent total loss of engine power. Contributing to the accident was a mechanic's failure to identify metallic particles contained in the oil filter element at the most recent 100-hour inspection.
