Federal Aviation Administration July 10, 2008 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Dassault Model Mystere-Falcon 50 Airplanes
Document Number: E8-15714
Type: Proposed Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; Pratt & Whitney (PW) JT9D-7 Series Turbofan Engines
Document Number: E8-15682
Type: Proposed Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for PW models JT9D-7, -7A, -7AH, -7H, -7F, and -7J turbofan engines. This proposed AD would require initial and repetitive borescope inspections of the 2nd stage high-pressure turbine (HPT) rotor and stator assembly. This proposed AD results from an uncontained failure of a 2nd stage HPT rotor disk that caused the engine to separate from the airplane. We are proposing this AD to prevent failure of the 2nd stage HPT rotor disk, which could result in uncontained engine failure, damage to the airplane, and the engine separating from the airplane.
Airworthiness Directives; Cirrus Design Corporation Model SR20 and SR22 Airplanes
Document Number: E8-15474
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to replace the cabin door rod ends with new parts including a redesigned non-binding hinge pin that replaces the existing pin at the upper door hinge. This AD results from two known occurrences of in-flight cabin door separation (one total separation and one retained by the door strut). The rod ends, a component of the door hinges, may fail and result in a door separation from the airplane while in flight. We are issuing this AD to prevent in-flight failure of the cabin door, which could result in door separation from the airplane.
Airworthiness Directives; Airbus Model A300 and A300-600 Series Airplanes
Document Number: E8-15265
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the products listed above. This 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:
Airworthiness Directives; Boeing 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
Document Number: E8-14972
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Boeing Model 747 airplanes listed above. This AD requires repetitive inspections for broken or missing fasteners in the single-row hinge fasteners of the forward and aft cargo doors, and related investigative/corrective actions. This AD results from reports of broken and missing fasteners in the hinges of the forward and aft cargo doors in both the body hinge segments and the door hinge segments. We are issuing this AD to detect and correct broken or missing fasteners in the hinge segments with a single fastener row, which could lead to opening of the cargo door during flight and result in rapid decompression of the airplane.
Airworthiness Directives; Bell Helicopter Textron Canada Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 Helicopters
Document Number: E8-14736
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The aviation authority of Canada, with which we have a bilateral agreement, states in the MCAI: ``It has been determined that some helicopters have been fitted with a CRES steel fitting, part number (P/N) 407-030-750-103, and the installation of the tailboom attachment bolt does not meet the design criteria.'' We are issuing this AD to require actions that are intended to address the unsafe condition that results from an improper installation of the tailboom attachment bolt in the upper left-hand tailboom attachment CRES steel fitting.
Airworthiness Directives; Lycoming Engines, Fuel Injected Reciprocating Engines
Document Number: E8-14734
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) for certain fuel injected reciprocating engines manufactured by Lycoming Engines. That AD currently requires inspection, and replacement if necessary, of externally mounted fuel injector fuel lines. This AD requires the same actions but adds additional engine models and clarifies certain compliance time wording. This AD also exempts engines that have a Maintenance and Overhaul Manual with an Airworthiness Limitations Section that requires inspection and replacement, if necessary, of externally mounted fuel injector lines. This AD results from Lycoming Engines revising their Mandatory Service Bulletin to add new engine models requiring inspection, and from the need to clarify a repetitive inspection compliance time. We are issuing this AD to prevent failure of the fuel injector fuel lines that would allow fuel to spray into the engine compartment, resulting in an engine fire.
Airworthiness Directives; Agusta S.p.A. Model AB 139 and AW 139 Helicopters
Document Number: E8-14720
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model AB 139 and AW 139 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, which indicates that the Agusta AB 139's and AW 139's Fuselage Frame 5700 middle section is prone to fatigue damage. The actions are intended to detect cracks in the fuselage frame structure and to prevent structural failure in this area.
Airworthiness Directives; Bell Helicopter Textron Canada Model 206L, L-1, L-3, L-4, and 407 Helicopters
Document Number: E8-14719
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The Aviation Authority of Canada with whom we have a bilateral agreement states in the MCAI: ``Horizontal stabilizers part numbers 206-023-119-167 and 407-023-801-109 may have manufacturing flaws on the inside surface of the upper and/or lower skin at the tailboom attachment inserts. These flaws may result in cracking of the skin and failure of the horizontal stabilizer.'' The manufacturer's service information states that in addition to cracks, the horizontal stabilizer may have deformation or debonding around and between the inserts. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron Canada Model 222, 222B, 222U, 230 and 430 Helicopters
Document Number: E8-14718
Type: Rule
Date: 2008-07-10
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 222, 222B, 222U, 230 and 430 helicopters that requires rewiring and testing the fuel valve switch on each engine and testing the ignitor system. This amendment is prompted by an in-flight incident in which a fuel valve switch failed, causing the fuel valve to inadvertently close. The actions specified by this AD are intended to prevent interruption of the fuel supply caused by failure of the fuel switch, which could result in loss of engine power and subsequent loss of control of the helicopter.
