Federal Aviation Administration January 5, 2017 – Federal Register Recent Federal Regulation Documents

This action proposes to establish 12 high altitude area navigation (RNAV) routes (Q-routes), and modify one existing Q-route, in support of the Atlantic Coast Route Project (ACRP). The ACRP goal is to implement a Performance Based Navigation (PBN) route structure within the heavily traveled and constricted airspace along the Atlantic coast of the United States (U.S.)

We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. This proposed AD was prompted by an unrecoverable engine in-flight shutdown (IFSD) after an ice crystal icing event. This proposed AD would require installing a software standard eligible for installation and preclude the use of electronic engine control (EEC) software standards earlier than SCN 5B/I. We are proposing this AD to correct the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH Helicopters (Airbus Helicopters) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD would require installing rivets to the air inlet cover rings (rings). This proposed AD is prompted by reports of rings detaching. The actions of this proposed AD are intended to prevent the unsafe condition on these products.

This action proposes to modify three jet routes and four VHF Omnidirectional Range (VOR) Federal airways; remove two VOR Federal Airway routes, and establish four and modify four low altitude Area Navigation (RNAV) routes (T-routes) in the western United States. The FAA is proposing this action due to the scheduled decommissioning of the Manteca, CA, and Maxwell, CA, VOR facilities, which provide navigation guidance for portions of the affected routes. This action would enhance the safety and management of aircraft within these routes in the National Airspace System (NAS).

We are superseding an airworthiness directive (AD) 2016-06-01 for B-N Group Ltd. Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN- 2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B- 21, BN-2B-26, BN-2B-27, BN-2T-4R, BN-2T, BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 (all models on Type Certificate Data Sheets A17EU and A29EU) airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated 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 cracks in the inner shell of certain pitot/static pressure heads. This AD changes model applicability due to errors found in AD 2016-06-01. We are issuing this AD to require actions to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757-200, -200PF, and -200CB series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that certain fuselage circumferential splice plates are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive low frequency eddy current (LFEC) inspections for cracks of certain circumferential splice plates, and repairs if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2014-12- 13, which applies to all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2014-12-13 currently requires repetitive inspections for cracking of the main landing gear (MLG) beam, and the rear spar upper chord and rear spar web; and repair if necessary. Since we issued AD 2014-12-13, we received reports of additional cracking in the inspar upper skin, rear spar web and rear spar upper chord. This proposed AD would expand the inspection area and add related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-26-08, for all Airbus Model A330-200, -200F, and -300 series airplanes. AD 2014-26-08 required revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. This new AD requires revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This new AD also removes certain airplanes from the applicability. This AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. We are issuing this AD to address the unsafe condition on these products.
