Airworthiness Directives; General Electric Company CF6-45A, CF6-50A, CF6-50C, and CF6-50E Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for General Electric Company (GE) CF6-45A, CF6-50A, CF6-50C, and CF6- 50E series turbofan engines. This proposed AD would require removing from service pre-GE Service Bulletin (SB) No. CF6-50 S/B 72-1268 configuration low pressure turbine (LPT) stage 2 interstage seal assemblies and stage 3 interstage seal assemblies. The proposed AD would also require installing new or reworked configuration stage 2 interstage seal assemblies and stage 3 interstage seal assemblies. This proposed AD results from reports of fan mid shaft separation, leading to separation of the LPT stage 1 disk, disk overspeed, and uncontained engine failure. We are proposing this AD to prevent uncontained engine failure and damage to the airplane.
Airworthiness Directives; Pacific Aerospace Corporation Ltd. Model 750XL Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Corporation Ltd Model 750XL airplanes. This proposed AD would require you to inspect the condition of the left and right outer panel attachment lugs for damage (scoring and gouging) and/or cracks (using a fluorescent penetrant inspection procedure for the crack inspection); to inspect the spacing of left and right outer panel attachment lugs; to replace the lugs if damage is found; and to make necessary corrections to the spacing. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are issuing this proposed AD to prevent structural failure of the outer panel and spar due to cracked, bent, or distorted condition of the left and right outer panel attachment lugs; and incorrect spacing of the left and right outer panel attachment lugs. This failure could lead to loss of control of the airplane.
Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
