Federal Aviation Administration June 27, 2013 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report of cracks in stringer splices at body station STA 360 and STA 908, between stringer (S) S-10L and S-10R; cracks in butt straps between S-5L and S- 3L, and S-3R and S-5R; vertical chem-mill fuselage skin cracks at certain butt joints; and an instance of cracking that occurred in all those three structural elements on one airplane. This proposed AD would require repetitive inspections for any cracking of stringer splices and butt straps, and related corrective and investigative actions if necessary. We are proposing this AD to detect and correct cracking in the three structural elements, which could result in the airplane not being able to sustain limit load requirements and possibly result in uncontrolled decompression.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. Title 49, United States Code, Sections 40117 (k) and 47106 (f) require that a covered airport submit a written competition plan to the Secretary/Administrator in order to receive approval to impose a Passenger Facility Charge (PFC) or to receive a grant under the Airport Improvement Program (AIP).

This action amends Class E Airspace at Selmer, TN, as the Sibley Non-Directional Beacon (NDB) has been decommissioned and new standard instrument approach procedures developed for Instrument Flight Rules (IFR) operations at Robert Sibley Airport. This enhances the safety and management of aircraft operations at the airport. This action also updates the geographic coordinates of the airport.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747SP series airplanes, and certain The Boeing Company Model 747-100B SUD and 747-300 series airplanes. This AD was prompted by an evaluation by the design approval holder indicating that the fuselage skin just above certain lap splice locations is subject to widespread fatigue damage. This AD requires repetitive inspections for cracking of the fuselage skin above certain lap splice locations, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin, which could result in reduced structural integrity of the airplane and sudden loss of cabin pressure.

We are adopting a new airworthiness directive (AD) for all B-N Group Ltd. Models BN-2, BN-2A, BN2A MK. III, BN2A MK. III-2, BN2A MK. III-3, BN-2A-2, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2A-3, BN-2A- 6, BN-2A-8, BN-2A-9, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T, and BN-2T-4R airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as inadequate sealing of the fuel filler cap (fuel tank cap) and the fuel filler receptacle (fuel tank opening), which could lead to contaminated fuel and result in in-flight shutdown of the engine. We are issuing this AD to require actions to address the unsafe condition on these products.
