Docket No. 99-SW-05-AD
Abstract
This amendment adopts a new airworthiness directive (AD) that applies to Eurocopter Model EC 135 helicopters. This AD requires replacing a certain oil cooler fan splined drive shaft (shaft) with a different airworthy shaft and re-identifying the part numbers on the oil cooler fans. This amendment is prompted by two incidents in which the shaft broke. The actions specified by this AD are intended to prevent failure of the shaft, loss of oil cooling, and a subsequent engine shutdown during flight.
