Recommendations for Facilities Realignments To Support Transition to NextGen as Part of Section 804 of the FAA Modernization and Reform Act of 2012-Part 3; Request for Comments
This document announces the availability of the FAA National Facilities Realignment and Consolidation Report, Part 3. The report was developed in response to Section 804 of the FAA Modernization and Reform Act of 2012. The report and recommendations contained therein have been developed collaboratively with the National Air Traffic Controllers Association (NATCA) and the Professional Aviation Safety Specialists (PASS) labor unions and with input from stakeholders. The FAA seeks comments on this report.
Airworthiness Directives; Embraer S.A. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD requires repetitive detailed inspections of the web aft face of the forward pressure bulkhead for any cracking and discrepancy; and modification of the forward pressure bulkhead, which would terminate the repetitive inspections. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the forward bulkhead is subject to widespread fatigue damage (WFD). We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; International Aero Engines AG Turbofan Engines
We are adopting a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5, and V2531-E5 turbofan engines. This AD was prompted following a self- disclosure by IAE regarding manufacturing quality escapes. This AD requires replacing the affected and suspect parts within the time limits specified in the compliance section. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We propose to remove Airworthiness Directive (AD) 2017-01-06, which applies to certain Airbus Model A319-115, A319-132, A320-214, A320-232, A321-211, A321-213, and A321-231 airplanes. AD 2017-01-06 requires inspection and replacement of certain tie rod assemblies installed on the hinged fairing assembly of the main landing gear (MLG). We issued AD 2017-01-06 to detect and correct the absence of cadmium plating on the rod end threads of the tie rod assemblies. Since we issued AD 2017-01-06, we have determined that although cadmium plating might be absent, the rod end threads of the tie rod assemblies can withstand the expected environmental conditions, therefore the unsafe condition, as initially determined, does not exist.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD requires removing the fasteners attaching the machined center fitting to the rear spar frame lower flange splice, inspecting the fasteners and fastener holes for damage, reworking and repairing the fastener holes, as applicable, and replacing the fasteners. This AD was prompted by a report indicating that certain fasteners attaching the machined rear spar center fitting to the frame were installed with a gap between the fastener head and the structure, or were installed tilted. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This proposed AD was prompted by a report that the main entrance door (MED) opened during flight, and by the determination that the ``CABIN DOOR UNLOCK'' crew alerting system (CAS) message may extinguish before the handle latch pin is fully engaged. This proposed AD would require accomplishing an updated rigging procedure for the adjustment of the MED microswitch. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream 100, Astra SPX, and 1125 Westwind Astra airplanes. This proposed AD was prompted by a report that the main entrance door (MED) opened during flight, and by the determination that the ``CABIN DOOR UNLOCK'' crew alerting system (CAS) message may extinguish before the handle latch pin is fully engaged. This proposed AD would require accomplishing an updated rigging procedure for the adjustment of the MED microswitch. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601 Variant), and CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes. This proposed AD was prompted by a report of laminated shims that may have been improperly installed at a certain wing tie beam. This proposed AD would require revising the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce revised checks of the tie beam. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model MD-11 and MD-11F airplanes. This AD was prompted by report of fuel odor in the cabin. Fuel was found leaking from a cracked fuel line shroud in the left cargo compartment equipment tunnel. This AD requires a check for the presence of fuel at the fuel shroud drain; a high frequency eddy current (HFEC) inspection for cracked fuel line shrouds; a pressure test of the drain system of the tail tank fuel shroud and a pressure test of the drain system of the aft fuselage fuel shroud to determine cracking; and corrective actions, if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2007-13-08, for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2007-13-08 required repetitive inspections of the auxiliary power unit (APU) starter motor, APU inlet plenum, and APU air intake for discrepancies; repetitive cleaning of the APU air intake; and applicable corrective actions. This AD expands the applicability of AD 2007-13-08, and includes an optional terminating installation for the repetitive actions. This AD was prompted by a determination that the unsafe condition could occur on additional airplanes. We are issuing this AD to address the unsafe condition on these products.
