Airworthiness Directives; The Boeing Company Model MD-90-30 Airplanes
We propose to adopt a new airworthiness directive (AD) for all Model MD-90-30 airplanes. This proposed AD would require repetitive eddy current high frequency (ETHF) inspections for cracking on the aft side of the left and right wing rear spar lower caps at station Xrs = 164.000, further ETHF inspections if cracks are found, and repair if necessary. This proposed AD would also require repetitive post-repair inspections and repair if necessary. This proposed AD was prompted by reports of cracks of the wing rear spar lower cap at the outboard flap, inboard drive hinge at station Xrs = 164.000. We are proposing this AD to detect and correct cracking of the left and right rear spar lower caps, which could result in fuel leaks and damage to the wing skin or other structure, and consequent loss of the structural integrity of the wing.
Airworthiness Directives; Learjet Inc. Model 45 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require revising the maintenance program to incorporate life limits for the main landing gear (MLG) actuator end cap. This proposed AD was prompted by a report of the potential for fatigue cracking of the end cap of the MLG prior to the published life limitation. We are proposing this AD to prevent fatigue cracking of the end cap of the MLG, which could result in the failure of the MLG actuator upon landing, and failure of the MLG to extend or retract during flight.
Airworthiness Directives; Empresa Brasileira de Aeronáutica S.A. (EMBRAER) Model EMB-505 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Agency Information Collection Activities: Requests for Comments; Clearance of Reinstated Approval of Information Collection: Dealer's Aircraft Registration Certificate Application
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to reinstate a previously discontinued information collection. AC Form 8050-5 is an application for a dealer's Aircraft Registration Certificate which, under 49 United States Code 1404, may be issued to a person engaged in manufacturing, distributing, or selling aircraft.
Proposed Amendment of Class E Airspace; Tonopah, NV
This action proposes to modify Class E airspace at Tonopah Airport, Tonopah, NV. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Tonopah Airport, Tonopah, NV. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport. This action also would make a minor adjustment to the geographic coordinates of the airport.
Proposed Amendment of Class D and Modification of Class E Airspace; Grand Junction, CO
This action proposes to modify Class E airspace at Grand Junction Regional Airport, Grand Junction, CO. Additional controlled airspace is necessary to facilitate vectoring of Instrument Flight Rules (IFR) traffic from Grand Junction Regional Airport to en route. The FAA is proposing this action to enhance the safety and management of aircraft operations at Grand Junction Regional Airport. This action also would amend Class D and Class E airspace to update the airport name from Grand Junction, Walker Field.
Airworthiness Directives; Various Aircraft Equipped With Rotax Aircraft Engines 912 A Series Engine
We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This AD results from 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:
Airworthiness Directives; Turbomeca S.A. ARRIEL 2B and 2B1 Turboshaft Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Airworthiness Directives; Rolls-Royce plc (RR) RB211-524 Series Turbofan Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
