Federal Aviation Administration November 2, 2006 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bell Helicopter Textron Model 204B, 205A, 205A-1, 205B, 210, 212, 412, 412CF, and 412EP Helicopters
Document Number: E6-18462
Type: Proposed Rule
Date: 2006-11-02
Agency: Federal Aviation Administration, Department of Transportation
This document proposes adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 204B, 205A, 205A-1, 205B, 210, 212, 412, 412CF, and 412EP helicopters. The AD would require certain checks and inspections of each tail rotor blade assembly (T/R blade) at specified intervals and repairing or replacing, as applicable, any unairworthy T/R blade. This proposal is prompted by eight reports of T/R blade failures. The actions specified by the proposed AD are intended to prevent failure of a T/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
Document Number: E6-18461
Type: Proposed Rule
Date: 2006-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This proposed AD would require revising the Airworthiness Limitations Items (ALI) of the maintenance requirements manual to require additional inspection requirements of the maintenance requirements manual for certain principal structural elements (PSEs) related to fuselage cutouts and to reduce an inspection threshold for an existing ALI task on the aft entry door. This proposed AD results from data obtained from the manufacturer's fatigue testing. We are proposing this AD to detect and correct fatigue cracking of certain PSEs, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Pratt & Whitney PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, PW4090-3, and PW4098 Turbofan Engines
Document Number: E6-18368
Type: Rule
Date: 2006-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, PW4090-3, and PW4098 turbofan engines, with certain front turbine hub part numbers installed. This AD requires a onetime visual inspection of the anti-rotation slots in the front turbine hub, for a machining nonconformance, and its replacement if the inspection failed. This AD results from a report of a crack found in an anti-rotation slot of a front turbine hub, during overhaul shop inspection. The anti-rotation slot geometry was not machined in conformance with the design drawing during manufacture. We are issuing this AD to prevent uncontained engine failure, damage to the airplane, and injury to passengers.
Special Conditions: Boeing Commercial Airplane Group, Boeing Model 777 Series Airplane; Overhead Cross Aisle Stowage Compartments
Document Number: 06-9025
Type: Proposed Rule
Date: 2006-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA amends and supersedes proposed special conditions for the Boeing Model 777 series airplanes. The previous notice (Notice No. 25-06-09-SC) published on October 18, 2006 (71 FR 61432), did not reflect the final FAA position on the novel design feature, and was thus in error. This airplane, modified by Boeing Commercial Airplane Group, will have novel or unusual design features associated with overhead cross aisle stowage compartments. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These amended proposed special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Agency Information Collection Activity Seeking OMB Approval
Document Number: 06-9024
Type: Notice
Date: 2006-11-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register notice with a 60-day comment period soliciting comments on the following collection of information was published on June 28, 2006, vol. 71, no. 124, page 36869. The FAA Aviation Research and Development Grants Program establishes uniform policies and procedures for the award and administration of research grants to colleges, universities, and not for profit organizations.
