Federal Aviation Administration January 22, 2007 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; SOCATA-Groupe Aerospatiale TB 20 and TB 21 Airplanes
Document Number: E7-706
Type: Rule
Date: 2007-01-22
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 reports of interference between the wing spar lower boom and the wheel fairing attaching screw. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Dart 528, 529, 532, 535, 542, and 555 Series Turboprop Engines
Document Number: E7-687
Type: Rule
Date: 2007-01-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Dart 528, 529, 532, 535, 542, and 555 series turboprop engines. This AD requires a dimensional inspection of the intermediate pressure turbine (IPT) disk or an ultrasonic inspection of the seal arm contact between the high pressure turbine (HPT) and the IPT disk seal arm and rework or replacement of the IPT disk if wear outside acceptable limits is found. This AD results from reports of a number of HPT disk failures, some of which resulted in portions of the HPT disk being released. We are issuing this AD to prevent HPT disk failure, which can result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; EADS SOCATA TBM 700 Airplanes
Document Number: E7-685
Type: Rule
Date: 2007-01-22
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 a report of a master cylinder yoke failure. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce plc RB211 Trent 700 Series Turbofan Engines
Document Number: E7-684
Type: Rule
Date: 2007-01-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 700 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the high pressure-and-intermediate pressure (HP-IP) turbine internal and external oil vent tubes for coking and carbon buildup, and cleaning or replacing the vent tubes if necessary. This AD requires the same actions but uses more stringent tube replacement criteria than the previous AD. This AD results from a recent incident where an RB211 Trent 700 series turbofan engine had an oil vent tube rupture as a result of blockage, leading to significant loss of engine oil. The incident indicates that further measures are necessary to control carbon buildup in the oil vent tubes. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup, that could cause uncontained engine failure and damage to the airplane.
Noise Exposure Map Notice; Receipt of Noise Compatibility Program and Request for Review, Shreveport Regional Airport, Shreveport, LA
Document Number: 07-249
Type: Notice
Date: 2007-01-22
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by Shreveport Airport Authority for the Shreveport Regional Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR part 150 are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed noise compatibility program that was submitted for the Shreveport Regional Airport under part 150 in conjunction with the noise exposure map, and that this program will be approved or disapproved on or before July 11, 2007.
Airworthiness Directives; Airbus Model A310 Airplanes
Document Number: 07-201
Type: Rule
Date: 2007-01-22
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 cracking in the wing main landing gear (MLG) rib 5 forward attachment lug, which could affect the structural integrity of the MLG attachment. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
