Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher tubes. It was determined the defects were caused by corrosion. This proposed AD would require repetitive general visual inspections of the fire extinguisher tubes for cracking and corrosion, and replacement of any cracked tube with a serviceable tube, if necessary. We are proposing this AD to detect and correct cracking and corrosion in the fire extinguisher tubes, which could impact the capability to extinguish an engine fire, and possibly result in damage to the airplane and injury to the passengers.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2011-24- 05, for certain Airbus Model A330-201, -202, -203, -223, -243, -301, - 302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300 series airplanes. AD 2011-24-05 currently requires repetitive inspections for cracking of the hole(s) of the horizontal flange of the keel beam, and repair if necessary. Since we issued AD 2011-24-05, a determination was made that the rototest inspection and applicable corrective actions of a certain fastener hole were inadvertently omitted from the requirements in that AD. This proposed AD would change the inspection compliance times, and, for certain airplanes, would add a one-time ultrasonic inspection for cracking at a certain fastener hole. This proposed AD would also provide optional terminating action for the repetitive inspections. We are proposing this AD to detect and correct cracking of the fastener holes, which could result in rupture of the keel beam, and consequent reduced structural integrity of the airplane.
Notice of Availability for the Cal Black Memorial Airport Final Supplemental Environmental Impact Statement (Draft SEIS) and Section 4(f) Evaluation
In accordance with the National Environmental Policy Act of 1969 (NEPA, 42 U.S.C. 4321 et seq.) and Council on Environmental Quality regulations (40 CFR part 1500-1508), the Federal Aviation Administration announces the availability of the Final Supplemental Environmental Impact Statement (Final SEIS) and Section 4(f) Evaluation for the Cal Black Memorial Airport. The Section 4(f) Evaluation was prepared pursuant to Section 4(f) of the Department of Transportation Act of 1966 (recodified at 49 U.S.C. 303(c)).
Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop Engines
We are revising airworthiness directive (AD) 2014-17-08 for all Pratt & Whitney Canada Corp. (P&WC) PT6A-114 and PT6A-114A turboprop engines. AD 2014-17-08 required initial and repetitive borescope inspections (BSIs) of compressor turbine (CT) blades, and the removal from service of blades that fail inspection. This new AD adds an additional single crystal CT blade, reduces the affected population, and corrects the Credit for Previous Action paragraph. This AD was prompted by P&WC development of an additional single crystal CT blade that corrects the unsafe condition. We are issuing this AD to prevent failure of CT blades, which could result in damage to the engine and damage to the airplane.
Airworthiness Directives; Pilatus Aircraft LTD. Airplanes
We propose to adopt a new airworthiness directive (AD) for Pilatus Aircraft Ltd. Model PC-12/47 and PC-12/47E airplanes. This proposed AD results from 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 the aileron trim tab disconnecting above 10,000 feet altitude. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This proposed AD was prompted by several reports of chafing of the wire bundles inside the electrical conduit of the forward and aft boost pumps of the numbers 1 and 4 main fuel tanks due to high vibration. These wire bundles can chafe through the wire sleeving into the insulation, exposing the wire conductors. This proposed AD would require replacing the wire bundles inside the electrical conduit of the forward and aft boost pumps of the numbers 1 and 4 main fuel tanks with new, improved wire bundles inserted into conduit liners. We are proposing this AD to prevent chafing of the wire bundles and subsequent arcing between the wiring and the electrical conduit creating an ignition source in the fuel tanks, which could result in a fire and consequent fuel tank explosion.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787 airplanes. This AD requires a repetitive maintenance task for electrical power deactivation on Model 787 airplanes. This AD was prompted by the determination that a Model 787 airplane that has been powered continuously for 248 days can lose all alternating current (AC) electrical power due to the generator control units (GCUs) simultaneously going into failsafe mode. This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this AD to prevent loss of all AC electrical power, which could result in loss of control of the airplane.
Proposed Establishment of Class E Airspace and Modification of Class D Airspace; Ogden, Hill AFB, UT
This action proposes to establish Class E airspace and modify Class D airspace at Hill Air Force Base (AFB), Ogden, UT. This action, initiated by the FAA's biennial review of the airspace area, would enhance the safety and management of Instrument Flight Rules (IFR) operations for Standard Instrument Approach Procedures (SIAPs) at the airport. This action would also update the geographic coordinates for Hill AFB, and Ogden-Hinckley Airport.
Proposed Amendment of Class D and Class E Airspace, Revocation of Class E Airspace; Salem, OR
This action proposes to modify Class D airspace, Class E surface area airspace, Class E airspace extending upward from 700 feet above the surface, and remove Class E surface area airspace designated as an extension at McNary Field, Salem, OR. After a biennial review, the FAA found it necessary to amend the airspace area for the safety and management of Instrument Flight Rules (IFR) operations for Standard Instrument Approach Procedures (SIAPs) at the airport.
Proposed Establishment of Class E Airspace, and Amendment of Class D and E Airspace; Ogden-Hinckley Airport, UT
This action proposes to establish Class E airspace as an extension to the Class D surface area, modify Class D airspace, and Class E airspace extending from 700 feet above the surface at Ogden- Hinckley Airport, Ogden, UT. This action, initiated by the FAA's biennial review of the airspace area, would enhance the safety and management of Instrument Flight Rules (IFR) operations for Standard Instrument Approach Procedures (SIAPs) at the airport. This action would also update the geographic coordinates of Ogden-Hinckley Airport and Hill AFB, Ogden, UT.
Airworthiness Directives; General Electric Company CT58 Turboshaft Engines
We propose to supersede airworthiness directives (ADs) 2001- 18-06 and 2008-22-16, which apply to certain General Electric Company (GE) CT58 turboshaft engines. ADs 2001-18-06 and 2008-22-16 require recalculating the lives of life-limited rotating parts using a Repetitive Heavy-Lift (RHL) multiplying factor and removal from service of parts that exceed the recalculated cyclic or hourly life limit. This proposed AD would consolidate ADs 2001-18-06 and 2008-22-16, and further reduce the life capability of certain parts. We are proposing this AD to prevent failure of life-limited rotating parts, uncontained part release, damage to the engine, and damage to the aircraft.
Airworthiness Directives; CFM International S.A. Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain CFM International S.A. (CFM) CFM56-7B series turbofan engines. This proposed AD was prompted by reports of uncommanded in-flight shutdowns (IFSDs) on CFM CFM56-7B engines following rupture of the 73- tooth gearshaft located in the engine accessory gearbox (AGB). This proposed AD would require magnetic chip detector (MCD) inspection of the affected gearshafts until removal. We are proposing this AD to prevent failure of certain engine AGB gearshafts, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane.
Proposed Amendment of Class E Airspace; Jupiter, FL
This action amends Class D Airspace at Jupiter, FL, by removing reference to Restricted Area R-2936 in the regulatory text of the Class D airspace area as the restricted area is no longer needed. This action also updates the geographic coordinates of the airport.
