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

Notice is being given that the FAA is considering a request from the Town of Nantucket in Nantucket, MA, to change the current land use from aeronautical use to non-aeronautical use of a 5 acre parcel of land. The parcel is located in the northwestern quadrant of the airport and is adjacent to other non-airport parcels used for industrial and/or commercial use properties. The parcel is currently identified as surplus for non-aeronautical use on the airport's September 16, 2015 Airport Layout Plan. The parcel will be used to generate non- aeronautical revenue through the lease of land for industrial/ commercial use. All revenues through the leasing of the parcel will continue to be subject to the FAA's revenue-use policy and dedicated to the maintenance and operation of Nantucket Memorial Airport.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracking in the upper aft skin at the rear spar of the wings. This proposed AD would require repetitive inspections for cracking of the upper aft skin of the wings, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for Northrop Grumman LITEF GmbH LCR-100 Attitude and Heading Reference System (AHRS) units installed on various aircraft. This proposed AD would require removing certain LCR-100 AHRS units from service. This proposed AD is prompted by test results showing loss of or invalid data. The proposed actions are intended to prevent an unsafe condition on these products.
