AD FAA-2012-0631

We are adopting 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 AD requires 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 AD was prompted by reports of cracks on the brackets. The actions of this AD are intended to prevent failure of the emergency flotation system and loss of float stability in the event of a water landing.
