Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2015-08-01, which applied to certain The Boeing Company Model 757 airplanes. AD 2015-08-01 required, depending on airplane configuration, installing new relays and bracket assemblies, inspecting to ensure that the new relays do not contact adjacent wire bundles, torqueing the bracket assembly installation nuts and ground stud nuts, retesting the bond resistance between the bracket assemblies and the terminal lugs on the ground studs, and doing related investigative and corrective actions if necessary. This AD does not retain any requirements, and instead requires deactivating the spoiler control module relays and capping and stowing the associated wiring on airplanes on which the actions required by AD 2015-08-01 have been done. This AD was prompted by a report of an uncommanded spoiler movement during flap configuration just before landing, on an airplane on which the actions required by AD 2015-08-01 had been done. We are issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Class E Airspace: Muscatine, IA
This action proposes to amend Class E airspace designated as a surface area and amend Class E airspace extending upward from 700 feet above the surface at Muscatine Municipal Airport, Muscatine, IA. The FAA is proposing this action due to the decommissioning of the Port City VHF omnidirectional range (VOR) facility, which provided navigation guidance for the instrument procedures to this airport. The VOR has been decommissioned as part of the VOR Minimum Operational Network (MON) Program.
