Federal Aviation Administration September 7, 2017 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80A, CF6-80A1, CF6-80A2, CF6- 80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6- 80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B1F1, CF6-80C2B1F2, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B3F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2B8F, CF6- 80C2D1F, CF6-80C2L1F, and CF6-80C2K1F turbofan engines. This proposed AD was prompted by an uncontained failure of a high-pressure turbine (HPT) stage 2 disk. This proposed AD would require ultrasonic inspection (UI) of HPT stage 1 and 2 disks. We are proposing this AD to address the unsafe condition on these products.

The FAA is considering a proposal to change 3.44 acres of airport land from aeronautical use to non-aeronautical use and to authorize the sale of airport property located at Willow Run Airport, Detroit, Michigan. The aforementioned land is not needed for aeronautical use. The property is located in the southwest corner of the airport. It is outside of the airport operations area and is currently used as a Hazardous Waste Landfill. In 1996 the Federal Aviation Administration released 13.34 acres on this site to accommodate the Landfill. This proposal will release the remainder of the site. The proposed use will remain as a Hazardous Waste Landfill.
