Federal Aviation Administration October 25, 2011 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Rolls-Royce plc RB211-524 Series, RB211-Trent 700 Series, and RB211-Trent 800 Series Turbofan Engines
Document Number: 2011-27513
Type: Rule
Date: 2011-10-25
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; Rolls-Royce plc (RR) RB211-535 Series Turbofan Engines
Document Number: 2011-27512
Type: Proposed Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to all RR RB211-535E4-37, -535E4-B-37, -535E4-B-75, and -535E4-C-37 turbofan engines. The existing AD currently requires performing initial and repetitive visual and fluorescent penetrant inspections (FPI) of the low-pressure (LP) turbine stage 1, 2, and 3 discs to detect cracks in the discs. Since we issued that AD, we determined that the definition of shop visit is too restrictive in the existing AD. This proposed AD would continue to require those inspections and would change the definition of a shop visit to be less restrictive. We are proposing this AD to correct the definition of shop visit, and to detect cracks in the LP turbine stage 1, 2, and 3 discs, which could result in an uncontained release of LP turbine blades and damage to the airplane.
Airworthiness Directives; EADS CASA (Type Certificate Previously Held by Construcciones Aeronauticas, S.A.) Airplanes
Document Number: 2011-27485
Type: Proposed Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Model CN-235-100, CN-235-200, and CN-235-300 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:
Airworthiness Directives; The Boeing Company Model 757 Airplanes
Document Number: 2011-27484
Type: Proposed Rule
Date: 2011-10-25
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 repetitive detailed inspections for discrepancies of the horizontal stabilizer ballscrew assembly; repetitive lubrication of the horizontal stabilizer trim control system; repetitive measurements for discrepancies of the ballscrew to ballnut freeplay; and corrective actions if necessary. This proposed AD was prompted by a report of extensive corrosion of the ballscrew of the drive mechanism of the horizontal stabilizer trim actuator. We are proposing this AD to prevent undetected failure of the primary and secondary load paths for the ballscrew in the horizontal stabilizer, which could lead to loss of control of the horizontal stabilizer and consequent loss of control of the airplane.
Airworthiness Directives; Airbus Model A310 Series Airplanes
Document Number: 2011-27393
Type: Rule
Date: 2011-10-25
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:
Establishment of Class E Airspace; Tatitlek, AK
Document Number: 2011-27368
Type: Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
This action establishes Class E airspace at Tatitlek, AK, to accommodate the creation of one standard instrument approach procedure at the Tatitlek Airport. The FAA is taking this action to enhance safety and management of Instrument Flight Rules (IFR) operations at the Tatitlek Airport.
Modification of Class B Airspace; Seattle, WA
Document Number: 2011-27367
Type: Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
This action modifies Seattle, WA Class B airspace to ensure the containment of large turbine-powered aircraft operating to and from the Seattle-Tacoma International Airport. The FAA is taking this action to enhance safety, improve the flow of air traffic, and reduce the potential for midair collision in the Seattle, WA terminal area.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
Document Number: 2011-27361
Type: Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Airworthiness Directives; Airbus Airplanes
Document Number: 2011-27005
Type: Rule
Date: 2011-10-25
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A310 series airplanes; 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:
