Federal Aviation Administration February 8, 2018 – 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.

This action modifies Class E airspace extending upward from 700 feet above the surface at Fort Scott Municipal Airport, Fort Scott, KS, and Phillipsburg Municipal Airport, Phillipsburg, KS. This action is required due to the decommissioning of the Fort Scott non- directional radio beacon (NDB) and the Phillipsburg NDB, and the cancellation of the associated instrument approach procedures. This action enhances the safety and management of instrument flight rules (IFR) operations at these airports.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a determination that the safe life limits of the horizontal stabilizer trim actuator (HSTA) attachment pins and trunnions were not listed in certain airworthiness limitations (AWLs) and that the HSTA attachment pins and trunnions were not serialized. This proposed AD would require revision of the maintenance or inspection program, as applicable, to include the latest revision of the AWLs, serialization of the HSTA attachment pins and trunnions, and repair or replacement of damaged HSTA attachment pins and trunnions. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2016-23- 01, which applies to all Airbus Model A310 series airplanes. AD 2016- 23-01 requires repetitive detailed inspections for cracking around the fastener holes in certain areas of the wing top skin panels, supplemental repetitive ultrasonic inspections for cracking around the fastener holes in certain other areas of the wing top skin panels, and repair if necessary. Since we issued AD 2016-23-01, an evaluation done by the design approval holder (DAH) indicates that the wing top skin panel attachment holes at a certain area are also subject to widespread fatigue damage (WFD). This proposed AD would add an inspection and modification of the attachment holes of the wing top skin panels at a certain area. This proposed AD also includes terminating action for certain inspections. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain 328 Support Services GmbH Model 328-300 airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by a determination that incomplete inspection instructions exist for the skin under outer and inner doublers left installed after the removal of a certain data link system. We are issuing this AD to address the unsafe condition on these products.
