Federal Aviation Administration November 2, 2011 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Cirrus Design Corporation Airplanes
Document Number: 2011-28382
Type: Proposed Rule
Date: 2011-11-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SR22T airplanes. This proposed AD was prompted by reports of partial loss of engine power due to a dislodged rubber gasket/seal being ingested into the turbocharger. This proposed AD would require inspection and modification of the air box flange welds and slots and installation of induction system air box seals as applicable. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Model A319 and A320 Series Airplanes
Document Number: 2011-28368
Type: Proposed Rule
Date: 2011-11-02
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; Dassault Aviation Model Mystere-Falcon 50 Airplanes

Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Model 204B, 205A, 205A-1, 205B, and 212 Helicopters
Document Number: 2011-28361
Type: Proposed Rule
Date: 2011-11-02
Agency: Federal Aviation Administration, Department of Transportation
This document proposes superseding four existing airworthiness directives (ADs) for the specified Bell model helicopters. Two of the existing ADs require an initial and repetitive inspection of certain part-numbered main rotor yokes installed on Bell Model 204B, 205A-1, and 212 helicopters. Two other existing ADs also establish a retirement life of 3,600 hours time-in-service (TIS) for certain part-numbered main rotor yokes installed on the Bell Model 204, 205 series, and 212 series helicopters. Those ADs were prompted by reports of cracks in the main rotor yoke (yoke). This action would retain the requirements of the existing ADs and would apply these inspections and retirement lives to additional part-numbered yokes. This action would also increase the inspection frequency for certain yokes installed on a Bell Model 205B or 212 helicopter and would require replacing any unairworthy yoke. This proposal is prompted by the need to expand the applicability to include yokes produced under a Parts Manufacturing Approval (PMA) whose design approval was based on identicality with the affected Bell yoke parts and a recent discovery of a cracked yoke. The actions specified by the proposed AD are intended to prevent cracking of a yoke, failure of the yoke, and subsequent loss of control of the helicopter.
Airworthiness Directives; General Electric Company Turboshaft Engines
Document Number: 2011-28353
Type: Rule
Date: 2011-11-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) CT7-8A, CT7-8A1, CT7-8E, and CT7-8F5 turboshaft engines with a fuel filter differential pressure switch, part number (P/N) TD028VF0H7Y5 (part of the fuel filter assembly, P/N 4110T53P06) installed. This AD requires daily visual inspections of the fuel filter differential pressure switch for fuel leaks and for excessive cracking of the switch mounting flanges due to stress- corrosion. This AD also requires the installation of a collar kit over the fuel filter differential pressure switch as terminating action to the daily inspections. This AD was prompted by reports of 47 fuel filter differential pressure switches found with stress-corrosion cracking of the mounting flanges. We are issuing this AD to prevent unrecoverable in-flight engine shutdown, engine bay fire due to fuel leakage, and forced landing or accident.
Airworthiness Directives; Rolls-Royce Corporation Turbofan Engines
Document Number: 2011-28352
Type: Rule
Date: 2011-11-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Rolls- Royce Corporation (RRC) AE 3007A, AE 3007A1/1, AE 3007A1, AE 3007A1/3, AE 3007A1E, AE 3007A1P, and AE 3007A3 turbofan engines. This AD requires initial and repetitive eddy current inspections (ECI) of certain 6th-through-13th stage compressor wheel knife edge seals, and initial and repetitive ECIs of the compressor wheel outer circumference, for cracks. This AD was prompted by reports of low-cycle fatigue cracks found during shop visits, in the 6th-through-13th stage compressor wheels having chrome-carbide coated or uncoated knife edge seals. We are issuing this AD to prevent uncontained failure of the 6th-through-13th stage compressor wheel, leading to damage to the airplane.
Amendment of Class E Airspace; Spearfish, SD
Document Number: 2011-28289
Type: Rule
Date: 2011-11-02
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class E airspace at Spearfish, SD, to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Black Hills AirportClyde Ice Field, and updates the geographic coordinates of the airport. There also is a minor correction to the coordinates of controlled airspace 1,200 feet above the surface, and a minor change in the airport name. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
