Airworthiness Directives; United Instruments, Inc. Series Altimeters
We propose to adopt a new airworthiness directive (AD) for certain United Instruments, Inc. 5934 series altimeters that were manufactured between January 2015 and February 2016 and installed in airplanes and helicopters. This proposed AD was prompted by reports of certain altimeters displaying higher than actual altitude due to a slow diaphragm leak. This proposed AD would require replacing the affected altimeters. We are issuing this proposed AD to prevent display of misleading altitude data, which could result in inadvertent flight into terrain.
Amendment and Establishment of Restricted Areas; Chincoteague Inlet, VA
This action expands the restricted airspace at Chincoteague Inlet, VA, to support the National Aeronautics and Space Administration's (NASA) Wallops Island Flight Facility (WFF) test requirements. This action adds 3 new restricted areas, designated R- 6604C, R-6604D, and R-6604E. Additionally, a minor change is made to 2 points in the boundary of existing area R-6604A to match the updated 3- nautical mile (NM) line from the shoreline of the United States (U.S.) as provided by the National Oceanic and Atmospheric Administration (NOAA).
Proposed Amendment of Class E Airspace, Trinidad, CO
This action proposes to modify Class E surface area airspace, and Class E airspace extending upward from 700 feet above the surface, at Perry Stokes Airport, Trinidad, CO. Airspace redesign is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at the airport due to the decommissioning of the Trinidad Non-Directional Radio Beacon (NDB) and cancellation of associated approaches. This action would ensure the safety, efficiency, and management of Instrument Flight Rules (IFR) operations at the airport. Additionally, the airport's geographic coordinates would be updated to match the FAA's aeronautical database.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-22- 12, for all Airbus Model A330-243, -243F, -341, -342, and -343 airplanes. AD 2012-22-12 currently requires inspecting piccolo tubes, piccolo tube mount links, the aft side of the forward bulkhead, and outer boundary angles (OBAs) for cracks, fractures, and broken links, and doing corrective actions if necessary. Since we issued AD 2012-22- 12, we have received reports of loose and missing attachment rivets of the inner boundary angles (IBA) and OBA of the forward bulkhead. This proposed AD would retain certain requirements of AD 2012-22-12, and add repetitive inspections for pulled, loose, and missing attachment rivets of the IBA and OBA of the forward bulkhead, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct degraded structural integrity of the engine nose cowl, which in the case of forward bulkhead damage in conjunction with a broken piccolo tube, could lead to damage to the engine and operation in icing conditions with reduced thermal anti-ice (TAI) performance.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of aileron and rudder control cables which may have tensions that are beyond allowable limits. This proposed AD would require revising the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce functional tests of the control cable tension. We are proposing this AD to detect and correct out-of-tolerance tension in the control cables, which, with certain system failures and environmental conditions, could result in reduced controllability of the airplane.
