Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: 06-3797
Type: Rule
Date: 2006-04-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on March 31, 2006 (71 FR 16206). The error resulted in an incorrect Docket No. This AD applies to certain Airbus Model A300-600 series airplanes. This AD requires modifying nine bolt holes in the vertical flange to prevent cracking before the inspection threshold of AD 98-18- 02.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes
Document Number: 06-3796
Type: Rule
Date: 2006-04-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. That AD currently requires repetitive detailed and ultrasonic inspections of the thrust links of the rear engine mounts for any crack or fracture and corrective actions if necessary. This new AD requires repetitive replacement of the thrust links with new or overhauled thrust links, which ends the repetitive detailed and ultrasonic inspections. This AD results from the finding of fractured and cracked forward lugs of the rear engine mount thrust link on the number one strut on two airplanes. We are issuing this AD to prevent cracked or fractured thrust links that could lead to the loss of the load path for the rear engine mount bulkhead and damage to other primary engine mount structure, which could result in the in-flight separation of the engine from the airplane and consequent loss of control of the airplane.
Amendment To Grant Criteria for Alcohol-Impaired Driving Prevention Programs
Document Number: 06-3781
Type: Rule
Date: 2006-04-21
Agency: National Highway Traffic Safety Administration, Department of Transportation
This final rule amends the regulation that implements 23 U.S.C. 410, under which States can receive incentive grants for alcohol-impaired driving prevention programs. The final rule implements changes that were made to the Section 410 program by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy For Users (SAFETEA-LU). SAFETEA-LU provides States with two alternative means to qualify for a Section 410 grant. Under the first alternative, States may qualify as a ``low fatality rate State'' if they have an alcohol- related fatality rate of 0.5 or less per 100 million vehicle miles traveled (VMT). Under the second alternative, States may qualify as a ``programmatic State'' if they demonstrate that they meet three of eight grant criteria for fiscal year 2006, four of eight grant criteria for fiscal year 2007, and five of eight grant criteria for fiscal years 2008 and 2009. Qualifying under both alternatives does not entitle the State to receive additional grant funds. SAFETEA-LU also provides for a separate grant to the ten States that are determined to have the highest rates of alcohol-related driving fatalities. This final rule establishes the criteria States must meet and the procedures they must follow to qualify for Section 410 grants, beginning in FY 2006.
Airworthiness Directives; Pratt & Whitney Canada (PWC) PW535A Turboshaft Engines
Document Number: 06-3765
Type: Rule
Date: 2006-04-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney Canada (PWC) PW535A turboshaft engines with serial numbers (SNs) lower than DC0241, and with hydromechanical fuel control (HFC) part number (P/N) 819735-4, 819735-5, or 819735-6 installed. This AD requires inspection and verification of the proper adjustment of the ratio unit setscrew adjustment of installed HFC units. This AD results from incidents of PW535A turboshaft engines experiencing lack of response to the power lever input during attempted engine acceleration, due to an incorrect adjustment of the HFC ratio unit setscrew. We are issuing this AD to prevent lack of engine response to power lever input, which could cause a single or dual engine in-flight shutdown event.

Proposed Establishment of Offshore Airspace Area 1485L; and Revision of Control 1485H; Barrow, AK
Document Number: E6-5908
Type: Proposed Rule
Date: 2006-04-20
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish Control 1485L and revise Control 1485H offshore airspace in the vicinity of Barrow, AK. These proposed actions would establish controlled airspace outside of 12 nautical miles (NM) of the U.S. shoreline upward from 1,200 feet mean sea level (MSL) along the North Slope of Alaska. Additionally, this proposal would revise the altitudes of Control 1485H from FL 230/FL 450 to FL 180/FL 600. The FAA is proposing these actions to provide additional controlled airspace for aircraft executing instrument flight rules (IFR) operations at the airfields along the North Slope of Alaska in anticipation of establishing Terminal Arrival Areas associated with Area Navigation (RNAV) Standard Instrument Arrival Procedures (SIAPs).

Airworthiness Directives; Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 Turbofan Engines
Document Number: E6-5843
Type: Proposed Rule
Date: 2006-04-19
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD). This proposed AD is for Pratt & Whitney (PW) PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines that were reassembled with certain previously used high pressure compressor (HPC) exit brush seal assembly parts and certain new or refurbished HPC exit diffuser air seal inner lands. This proposed AD would require replacing the HPC exit inner and outer brush seal packs with new brush seal packs, or replacing the HPC exit brush seal assembly with a new HPC exit brush seal assembly. This proposed AD results from a report of oil leaking into the high pressure turbine (HPT) interstage cavity and igniting, leading to an uncontained failure of the 2nd stage turbine air seal and engine in-flight shutdown. We are proposing this AD to prevent uncontained engine failure, damage to the airplane, and injury to passengers.

Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Air Tractor, Inc. (Air Tractor) Models AT-400, AT-401, AT-401B, AT-402, AT-402A, and AT-402B airplanes. This AD requires you to lower the safe life for the wing lower spar cap for certain Models AT-402A and AT-402B airplanes and those that incorporate or have incorporated Marburger Enterprises, Inc. (Marburger) winglets. For Models AT-400, AT-401, AT-401B, AT-402, and certain AT-402A, airplanes, this AD requires you to repetitively inspect the wing lower spar cap in order to reach the safe life. We also developed an alternative method of compliance (AMOC) to the requirements of this Ad for certain Models AT- 402A and AT-402B airplanes. The AMOC includes repetitive eddy current inspections, modification of the center splice connection, and lower spar cap replacement. This AD is the result of reports of cracks in the \3/8\-inch bolt hole of the wing lower spar cap before reaching the approved safe life. We are issuing this AD to prevent fatigue cracks from occurring in the wing lower spar cap before the originally established safe life is reached. Fatigue cracks in the wing lower spar cap, if not detected and corrected, could result in wing separation and loss of control of the airplane.
Airworthiness Directives; Air Tractor, Inc. Models AT-802 and AT-802A Airplanes

Document Number: E6-5723
Type: Proposed Rule
Date: 2006-04-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections to detect cracks in the vertical beam webs of the body station (BS) 178 bulkhead, and corrective actions if necessary. This proposed AD also would require a terminating modification for the repetitive inspections. This proposed AD results from reports of numerous cracks in the vertical beam webs. We are proposing this AD to prevent fatigue cracks in certain vertical beam webs, which could result in loss of structural integrity of the BS 178 bulkhead, and consequently could impair the operation of the control cables for the elevators, speed brakes, and landing gear, or could cause the loss of cabin pressure.

On September 7, 2005 the FAA determined that the noise exposure maps submitted by the Niagara Frontier Transportation Authority under Part 150 were in compliance with applicable requirements. On March 3, 2006, the FAA approved Buffalo Niagara International Airport's noise compatibility program. Most of the recommendations of the program update were approved. Four measures were disapproved for Part 150 purposes.
Aging Aircraft Program: Widespread Fatigue Damage
Document Number: 06-3621
Type: Proposed Rule
Date: 2006-04-18
Agency: Federal Aviation Administration, Department of Transportation
This action is intended to prevent widespread fatigue damage by proposing to require that design approval holders establish operational limits on transport category airplanes. Design approval holders would also be required to determine if maintenance actions are needed to prevent widespread fatigue damage before an airplane reaches its operational limit. Operators of any affected airplane would be required to incorporate the operational limit and any necessary service information into their maintenance programs. Operation of an affected airplane beyond the operational limit would be prohibited, unless an operator has incorporated an extended operational limit and any necessary service information into its maintenance program.
Airworthiness Directives; Rolls-Royce plc RB211 Trent 800 Series Turbofan Engines
Document Number: E6-5666
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Aviation Administration, Department of Transportation
This action withdraws a notice of proposed rulemaking (NPRM). That NPRM proposed to revise the existing airworthiness directive (AD) applicable to Rolls-Royce plc (RR) Model RB211 Trent 892, 884, 877, 875, and 892B series turbofan engines. That proposed rule would have required initial and repetitive inspections of the angled drive upper shroud, the intermediate gearbox housing (IGH), and the external gearbox lower bevel box (LBB) housing, and initial and repetitive master magnetic chip detector (MCD) inspections. Since we issued that proposed rule, RR notified us that after reviewing the service experience and the original actions taken, the unsafe condition no longer exists and mandatory actions required by the proposed rule are no longer required. Accordingly, we withdraw the proposed rule.
Construction and Maintenance
Document Number: E6-5651
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Highway Administration, Department of Transportation

Airworthiness Directives; Turbomeca Arriel 1B, 1D, 1D1, and 1S1 Turboshaft Engines
Document Number: E6-5646
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to revise an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD currently requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD also currently requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. This proposed AD revision would require the same actions, but would relax the compliance times for initially replacing 2nd stage turbines in Arriel 1B, 1D, and 1D1 turboshaft engines. This proposed AD revision results from a request by Turbomeca to clarify the compliance times for 2nd stage turbine initial replacement on Arriel 1D, 1D1, and 1B turboshaft engines. We are proposing this AD revision to clarify and relax the AD compliance times for 2nd stage turbine initial replacement on Arriel 1B, 1D, and 1D1 turboshaft engines. We are also proposing this AD revision to prevent inflight engine shutdown and subsequent forced autorotation landing or accident.

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-50C series turbofan engines. This proposed AD would require reworking the forward fan stator case and installing a fan module secondary containment shield. This proposed AD results from reports of uncontained fan blade failures causing damage and separation of airplane hydraulic lines. We are proposing this AD to prevent uncontained fan blade failures, which can result in separation of airplane hydraulic lines, damage to critical airplane systems, and possible loss of airplane control.
