Airworthiness Directives; Eurocopter France Helicopters

We propose to adopt a new airworthiness directive (AD) for Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters with certain Aerazur emergency flotation gear attachment brackets (brackets) installed. This proposed AD would require an initial and recurring inspection of the brackets for a crack, and if there is a crack, replacing the cracked bracket with an airworthy bracket. This proposed AD is prompted by reports of cracks on the brackets. The proposed actions are intended to prevent failure of the emergency flotation system and loss of float stability in the event of a water landing.
