Federal Aviation Administration October 31, 2019 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for The Boeing Company (Boeing) Model 777 series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is an inertia locking device (ILD) installed in passenger seats. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This notice announces a meeting of the ARAC.

The FAA proposes to adopt a new airworthiness directive (AD) for various helicopters operating under experimental airworthiness certificates and various type certificated restricted category helicopters. This proposed AD was prompted by multiple accidents and incidents involving failure of the tail boom attachment structure and bolts. This proposed AD would require revising the Rotorcraft Flight Manual (RFM) for your helicopter to incorporate pre-flight checks; removing paint and sealant, and cleaning; repetitive inspections of structural components that attach the tail boom to the fuselage; and depending on the outcome of the inspections, repairing or replacing components, or re-bonding the structure. The FAA is proposing this AD to address the unsafe condition on these products.
