Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This proposed AD was prompted by a report of a main rotor gearbox (MGB) flange assembly coupling (coupling) that was incorrectly assembled. This proposed AD would require a one-time visual inspection to determine correct assembly of each sliding flange installed on each MGB coupling, and if necessary, further corrective actions. This proposed AD would also prohibit installing certain MGB couplings or any MGB equipped with certain MGB couplings on any helicopter. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters.
