Docket No. 98-SW-57-AD
Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA. 315B helicopters. This action requires inspecting the spar skin and main rotor blade (blade) root reinforcement strip area for bonding separation, corrosion, or a crack, and replacing the blade, if necessary. This amendment is prompted by the in-flight failure of a blade. The actions specified in this AD are intended to detect bonding separation, corrosion, or a crack in the area of the blade root reinforcement strip, which could result in failure of the blade and subsequent loss of control of the helicopter.
