Federal Aviation Administration June 9, 2020 – Federal Register Recent Federal Regulation Documents

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA is superseding Airworthiness Directive (AD) 2010-23- 04, which applied to all De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. AD 2010-23-04 required repetitive detailed inspections of the nacelle attachment fittings for cracks, a conductivity inspection of the nacelle attachment fittings, and replacement if necessary. This AD continues to require these inspections and replacement if necessary, removes a certain inspection requirement for certain airplanes, and adds a new requirement to replace the rear spar fitting and nacelle attaching structure with a new nacelle attachment fitting. This AD was prompted by a determination that it is necessary to do a replacement with new nacelle attachment fittings. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Inc. (Type Certificate previously held by Bell Helicopter Textron Inc.) (Bell), Model 204B, 205A-1, and 212 helicopters. This proposed AD was prompted by reports of corrosion on main rotor hub tension-torsion strap (TT strap) assemblies. This proposed AD would require reducing the life limit of a certain part- numbered TT strap assembly and prohibit installing this TT strap assembly on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to modify the Class D and Class E surface area at Bethel Airport, Bethel AK, by redefining the Hangar Lake exclusion area and eliminating the use of the VORTAC in the descriptions. This action also proposes to remove Class E airspace as an extension to the Class D and Class E surface area and modify the Class E airspace extending upward from 700 feet above the surface at the Airport. After a biennial review of the airspace, the FAA found it necessary to amend the existing airspace for the safety and management of Instrument Flight Rules (IFR) operations at this airport. This action would also update the geographical coordinates and make a minor editorial change replacing the outdated term Airport/Facility Directory with the term Chart Supplement.
