Airworthiness Directives; General Electric Company CF6-80A Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80A series turbofan engines with a high-pressure turbine rotor (HPTR) stage 1 disk, part number (P/N) 9367M45G06, installed. This AD requires removing any HPTR stage 1 disk, P/N 9367M45G06, before exceeding 2,075 cycles-since-new (CSN). This AD results from an error by GE that incorrectly cited a cyclic life of 12,600 CSN for the HPTR stage 1 disk, P/N 9367M45G06. We are issuing this AD to prevent the HPTR stage 1 disk from exceeding its part life, which could cause fatigue cracks to start and grow. These cracks could result in a possible uncontained disk failure and damage to the airplane.
Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, -300, -400, -400D, -400F, and 747SR Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes identified above. This proposed AD would require replacing the inboard trailing edge (TE) flap transmission carbon disk no-back brakes with skewed roller no-back brakes at the TE flap transmission, positions 4 and 5. This proposed AD results from reports of the inboard TE flaps blowing back due to the failure of a transmission carbon disk no-back brake. The no-back brake did not hold the TE flaps in the commanded position. We are proposing this AD to prevent a decrease of the aerodynamic controllability of the airplane, which could adversely affect the airplane's continued safe flight and landing.
Airworthiness Directives; Airbus Model A300, A310, and A300-600 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300 and A310 series airplanes. The existing AD currently requires replacement of the nose landing gear drag strut upper attachment pin. This proposed AD would require revising the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to require additional life limits and/or replacements for certain main landing gear and nose landing gear components, and would also expand the applicability. This proposed AD results from revisions to the ALS of the ICA to include new or more restrictive life limits and/or replacements. We are proposing this AD to ensure the continued structural integrity of these airplanes.
Noise Exposure Map Notice; Receipt of Noise Compatibility Program and Request for Review; Kansas City International Airport, Kansas City, MO
The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by the Kansas City Aviation Department for the Kansas City International Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act, herein after referred to as ``the Act'') and 14 Code of Federal Regulations (CFR) part 150 (hereinafter referred to as ``Part 150'') are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed noise compatibility program that was submitted for the Kansas City International Airport under Part 150 in conjunction with the noise exposure map, and that this program will be approved or disapproved on or before September 16, 2009.
