NTSB Safety Recommendations A-08-77 and -78

************************************************************

The National Transportation Safety Board recommends that the 
European Aviation Safety Agency:

Require Eurocopter to identify AS-350 and EC-130 helicopter 
hydraulic pump drive shafts and coupling sleeves with 
splines that do not meet design specifications and take 
appropriate action to ensure that these parts (that is,
replacement parts and parts to be installed in new 
helicopters) are expeditiously removed from the supply 
chain. (A-08-77)

Require operators of Eurocopter AS-350 and EC-130 
helicopters to perform a wear check, visual inspection, and 
lubrication of the hydraulic power assembly splines and 
coupling sleeve splines in accordance with the latest 
version of the maintenance manual at the earliest 
opportunity, and, thereafter, require operators to repeat 
the wear check, visual inspection, and lubrication of the 
splined connection at 100-hour intervals, and remove 
unairworthy parts from service. (A-08-78)
