Federal Aviation Administration July 1, 2014 – Federal Register Recent Federal Regulation Documents

We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200PF, -200CB, and -300 series airplanes. The NPRM proposed to require, for certain airplanes, installing new relays adjacent to two of the spoiler control modules. For certain other airplanes, the NPRM proposed to require torquing the bracket assembly installation nuts and ground stud nuts, and doing bond resistance tests between the bracket assemblies and the terminal lugs on the ground studs. The NPRM was prompted by numerous reports of unintended lateral oscillations during final approach, just before landing. This action revises the NPRM by adding actions that are necessary to address the identified unsafe condition. We are proposing this supplemental NPRM (SNPRM) to reduce the chance of unintended lateral oscillations near touchdown, which could result in loss of lateral control of the airplane, and consequent airplane damage or injury to flight crew and passengers. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of an incorrectly assembled check tee fitting used in fire extinguishing (FIREEX) distribution lines. This proposed AD would require inspecting to determine the part number and for all affected check tee fittings measuring for correct depth, and replacing if necessary. We are proposing this AD to detect and correct faulty check tee fittings, which will reduce fire extinguishing protection.

This action establishes Class E airspace at Memphis, MO. Controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Memphis Memorial Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

We are superseding Airworthiness Directive (AD) 2007-10-16 for all British Aerospace Regional Aircraft Jetstream Model 3201 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 the need to incorporate revisions to the Airworthiness Limitations section of the Instructions for Continued Airworthiness. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892- 17, 892B-17, and 895-17 turbofan engines. This AD requires inspection of the affected low-pressure (LP) turbine bearing support and exhaust case assembly and, if necessary, its replacement with a part eligible for installation. This AD was prompted by thin-walled LP turbine bearing support and exhaust case assemblies having been delivered into service. We are issuing this AD to prevent failure of the LP turbine bearing support and exhaust case assembly, which could lead to engine separation and damage to the airplane.
