Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8 and -9 airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires revising certificate limitations and operating procedures of the airplane flight manual (AFM) to provide the flight crew with runaway horizontal stabilizer trim procedures to follow under certain conditions. This AD was prompted by analysis performed by the manufacturer showing that if an erroneously high single angle of attack (AOA) sensor input is received by the flight control system, there is a potential for repeated nose-down trim commands of the horizontal stabilizer. We are issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Multiple Air Traffic Service (ATS) Routes; Western United States
This action proposes to amend three domestic Very High Frequency Omnidirectional Range (VOR) Federal Airways (V-113, V-137, and V-485) in the western United States. The modifications are necessary due to the planned decommissioning of Priest, CA, VOR navigation aid (NAVAID), which provides navigation guidance for portions of the affected air traffic service (ATS) routes. The Priest, CA, VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
Amendment of VOR Federal Airways V-318 and V-352; Northeastern United States
This action modifies the descriptions of VHF Omnidirectional Range (VOR) Federal airways V-318 and V-352 to reflect the removal of certain route segments within Canadian airspace that were deleted by NAV CANADA. This rule modifies the above airway descriptions to match the current configuration of the routes.
Proposed Amendment of VOR Federal Airways V-128 and V-144 in the Vicinity of Kankakee, IL
This action proposes to amend VHF Omnidirectional Range (VOR) Federal airways V-128 and V-144 in the vicinity of Kankakee, IL. The modifications are necessary due to the planned decommissioning of the Kankakee, IL (IKK), VOR navigation aid (NAVAID), which provides navigation guidance for portions of the affected air traffic service (ATS) routes. The Kankakee VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports indicating there is a possibility of excessive error in the signal generated by the angle of attack (AOA) transducer. This proposed AD would require replacing certain AOA transducers. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318 and A319 series airplanes, Model A320- 211, -212, -214, -216, -231, -232, and -233 airplanes, and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by a report that taperloks used in a certain wing-to-fuselage junction were found to be non-compliant with the applicable specification, resulting in a loss of pre-tension in the fasteners. This proposed AD would require repetitive special detailed inspections of the center and outer wing box lower stiffeners and panels at a certain junction on the left- and right-hand sides for any cracking, and repair if necessary. 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 G150 airplanes. This proposed AD was prompted by reports of corrosion in the solder joints of the upper and lower front relay box connectors to the printed circuit board. This proposed AD would require replacement of the existing relay boxes with modified boxes. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; CFM International S.A. Turbofan Engines
We are adopting a new airworthiness directive (AD) for all CFM International S.A. (CFM) LEAP-1B21, -1B23, -1B25, -1B27, -1B28, - 1B28B1, -1B28B2, -1B28B2C, -1B28B3, -1B28BBJ1, and -1B28BBJ2 turbofan engines. This AD requires removing certain electronic engine control (EEC) system operation (OPS) and engine health monitoring (EHM) software and installing versions eligible for installation. This AD was prompted by six aborted takeoffs on the similarly designed CFM LEAP-1A model turbofan engine after those engines did not advance to the desired takeoff fan speed due to icing in the pressure sensor line. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of drainage holes on the belly fairing forward and middle access panels being obstructed with sealant. This AD requires inspecting for and removing all sealant blocking the drainage holes on the belly fairing forward and middle access panels. We are issuing this AD to address the unsafe condition on these products.
