Airworthiness Directives; Eurocopter France Helicopters

概要

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS332C, L, and L1 helicopters to require an initial and repetitive inspections of the outer skin, butt strap, and fuselage frame for a crack and modification of the helicopter. This proposed AD is prompted by an AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, which states that a crack was discovered in a fuselage frame during a daily check. The proposed actions are intended to detect a crack, to prevent loss of airframe structural integrity and subsequent loss of control of the helicopter.
