Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) CF34-8 model turbofan engines with a certain outer shell combustion liner (combustion outer liner shell) installed. This AD was prompted by two in-flight engine shutdowns (IFSDs) that occurred as a result of failures of the combustion outer liner shell. This AD requires a borescope inspection (BSI) or visual inspection of the combustion outer liner shell and, depending on the results of the inspection, possible replacement of the combustion outer liner shell. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by a report that an operator found solid rivets with missing heads at the left buttock line 25 on the sloping pressure deck web. This AD requires doing a detailed inspection of the left- and right-side sloping pressure deck at certain stations for any damaged solid rivets, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; DG Flugzeugbau GmbH Gliders
The FAA proposes to adopt a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Models DG-500MB and DG-1000M gliders with a Solo Kleinmotoren GmbH Solo Model 2625 02i engine installed. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an error in the engine control unit (ECU) software. This proposed AD would require updating the ECU software. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Models GV and GV- SP airplanes. This proposed AD was prompted by the omission of a life limit in the airworthiness limitations section (ALS) of the maintenance manual for a certain main landing gear (MLG) trunnion pin. This proposed AD would require revising the ALS of your existing instructions for continued airworthiness (ICA) or inspection program for the airplane to establish a life limit of 20,000 flight cycles for the affected MLG trunnion pin. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Amendment of VOR Federal Airways V-16, V-31, V-93, V-157, V-213, and V-229 in the Vicinity of Patuxent River, MD
The FAA is withdrawing the NPRM published in the Federal Register on July 12, 2017, proposing to amend VHF Omnidirectional Range (VOR) Federal airways V-16, V-31, V-93, V-157, V-213, and V-229 near Patuxent River, MD, due to the planned decommissioning of the Patuxent VOR/Tactical Air Navigation (VORTAC) (PXT), Patuxent River, MD, in support of the FAA's VOR Minimum Operational Network (MON) program. Subsequent to the NPRM, the PXT VORTAC decommissioning has been delayed until a to-be-determined date. The FAA decided that additional planning is necessary to ensure a more efficient implementation and integration with other ongoing VOR MON program activities, and determined that withdrawal of the proposed rule is warranted.
Airworthiness Directives; Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Daher Aerospace (type certificate previously held by SOCATA) Models TB 20 and TB 21 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks on the main landing gear (MLG) legs. This proposed AD would require repetitively inspecting the MLG and performing all applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2012-06-16, which applies to all Pilatus Aircraft Ltd. (Pilatus) Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC- 6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/ C-H2, and PC-6/C1-H2 airplanes. AD 2012-06-16 requires installing a new rudder and elevator locking screw and modifying the installation of the rudder and elevator hinge bolt. Since the FAA issued AD 2012-06-16, the European Union Aviation Safety Agency (EASA) superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would not retain any actions required by AD 2012-06-16 and would require inspecting and modifying the rudder, elevator, and right-hand (RH) aileron hinge bolt installations. The FAA is proposing this AD to address the unsafe condition on these products.
