Summary
We propose to adopt a new airworthiness directive (AD) for Romtex torso restraint systems (restraint systems) installed on but not limited to Airbus Helicopters Model AS350B2, AS350B3, EC130B4, EC130T2, and AS355NP helicopters. This proposed AD would require replacing certain restraint system buckles. This proposed AD is prompted by a report of several restraint system buckle knobs breaking. The proposed actions are intended to correct an unsafe condition on these products.
