Federal Aviation Administration October 5, 2011 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; General Electric Company (GE) CT7-8, CT7-8A, CT7-8A1, CT7-8E, and CT7-8F5 Turboshaft Engines
Document Number: 2011-25654
Type: Rule
Date: 2011-10-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the products listed above. This AD was prompted by four reports of unrecoverable engine stalls, during hover in a left-roll attitude. This AD requires the installation of an accessory gearbox (AGB) axis-A oil slinger nut to the axis-A shaft assembly. We are issuing this AD to prevent an unrecoverable engine stall, leading to a helicopter forced landing or accident.
Airworthiness Directives; Dowty Propellers Type R212/4-30-4/22 and R251/4-30-4/49 Propeller Assemblies
Document Number: 2011-25653
Type: Rule
Date: 2011-10-05
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) 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; 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 Airplanes
Document Number: 2011-25580
Type: Proposed Rule

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; The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER Series Airplanes
Document Number: 2011-25579
Type: Proposed Rule

Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require replacement of the thumbnail fairing edge seals on both sides of the engines with Nitronic 60 stainless steel alloy seals. This proposed AD was prompted by reports of excessive in-service wear damage of the thumbnail fairing edge seal and the fan cowl panel rub strip and fan cowl skin assembly. We are proposing this AD to prevent failure of the fire seal, which could allow a fire in the fan compartment to spread beyond the firewall and reach the flammable fluid leakage zones, resulting in an uncontrolled fire.
Airworthiness Directives; Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) Airplanes

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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; Airbus Model A330-200 Series Airplanes; Model A330-300 Series Airplanes; Model A340-200 Series Airplanes; and Model A340-300 Series Airplanes

Type: Rule

Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting to determine the clearance and any wire bundle damage between wire bundle W443 and the left forward rudder quadrant, followed by adjusting the minimum clearance between the wire bundle and the left forward rudder quadrant, and repairing any wire bundle damage. This AD was prompted by reports of contact between wire bundle W443 and the left forward rudder quadrant. We are issuing this AD to detect and correct contact between the wire bundle and the left forward rudder quadrant. Damage to the wire bundle from contact between the wire bundle and the left forward rudder quadrant could result in uncommanded stabilizer trim and autopilot disconnects due to shorted wires, potentially affecting the capability of the flightcrew during high work load and consequently reducing control of the airplane. Restricted movement of the rudder quadrant at full right rudder travel would reduce controllability of the airplane.
Airworthiness Directives; Airbus Airplanes
Document Number: 2011-25308
Type: Rule
Date: 2011-10-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4- 605R Variant F airplanes (collectively called A300-600 series airplanes). 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: * * * * * A recent analysis conducted by the manufacturer showed a particular risk for explosive failure of the * * * hydraulic accumulator. This condition, if not detected and corrected, might, for some aeroplane installations, lead to damage to all three hydraulic circuits, possibly resulting in loss of control of the aeroplane or could, for certain other aeroplane installations, lead to an undetected fire in the wheel bay. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
