Federal Aviation Administration January 7, 2010 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Model 777 Airplanes
Document Number: E9-31431
Type: Proposed Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Model 777 airplanes. This proposed AD would require inspecting the bolt, nut, and downstop of the slat track assembly to determine if the bolt, nut, or stops are missing and to determine if the thread protrusion of the bolt from the nut is within specified limits and parts are correctly installed, and related investigative and corrective actions if necessary. For certain airplanes, this proposed AD would also require inspecting the slat cans at the outboard slat number 3 and 12 outboard main track locations for holes and wear damage, and corrective actions if necessary; and replacing the downstop hardware for the outboard slats number 3 and 12 outboard and inboard main track locations. This proposed AD results from a report of a hole in the inboard main track slat can for outboard slat number 12 on a Model 777 airplane. The hole was caused when the bolt securing the downstop migrated out of the fitting and contacted the slat can. We are proposing this AD to detect and correct damage to the outboard slat main track slat cans, which can allow fuel leakage into the fixed wing leading edge in excess of the capacity of the draining system. Excess fuel leakage could result in an uncontained fire.
Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 Airplanes
Document Number: E9-31364
Type: Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
We are clarifying information contained in Airworthiness Directive (AD) 2009-21-08, which applies to PIAGGIO AERO INDUSTRIES S.p.A. (Piaggio) Model PIAGGIO P-180 airplanes. AD 2009-21-08 currently requires repetitive functional tests of the manifold system and replacement of any system that does not pass the functional tests (i.e., movement of the steering system). The language in AD 2009-21-08 incorrectly references not passing the functional tests as ``movement of the manifold,'' and it should read ``movement of the steering system'' as specified in the service bulletin. The notice of proposed rulemaking (NPRM) referenced it as specified in the service bulletin. This document incorporates the intent of the action as already proposed in the NPRM. We are issuing this AD to prevent a potentially dangerous veer along the runway. The steering system must be in the `off' position during landing and takeoff (in this case when airspeed is higher than 60 knots) according to the aircraft flight manual limitations.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
Document Number: E9-31311
Type: Rule
Date: 2010-01-07
Agency: Department of Transportation, Federal Aviation Administration
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; The Boeing Company Model 747-400, -400D, and -400F Series Airplanes
Document Number: E9-31070
Type: Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an existing airworthiness directive (AD), which applies to certain Model 747-400, -400D, and -400F series airplanes. That AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires phasing in certain repetitive AWL inspections, and repair if necessary. This AD clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; General Electric Company CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 Turbofan Engines
Document Number: E9-30471
Type: Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 turbofan engines. That AD currently requires a onetime visual and tactile inspection of certain areas of certain P/N and SN fan disks for an arc-out defect, within 20 engine flight hours after the effective date of that AD. This AD requires inspecting certain fan disks for electrical arc-out indications, removing from service fan disks with electrical arc-out indications, performing tactile and enhanced visual (TEV) inspections, fluorescent penetrant inspections (FPI), and eddy current inspections (ECI) on certain disks that have already had a shop-level inspection, and repetitive FPI and ECI on certain fan disks. This AD results from an updated risk analysis by GE that shows we need to take corrective action that is more stringent. We are issuing this AD to prevent an uncontained failure of the fan disk, which could result in damage to the airplane.
Airworthiness Directives; Honeywell International Inc. ALF502 Series and LF507 Series Turbofan Engines
Document Number: E9-29987
Type: Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) for Honeywell International Inc. ALF502 series and LF507 series turbofan engines with certain fuel manifold assemblies installed. That AD currently requires initial and repetitive on-wing eddy current or in-shop fluorescent penetrant inspections of certain part number (P/N) fuel manifold assemblies for cracks, and replacement of cracked fuel manifolds with serviceable manifolds. This AD continues to require inspecting those fuel manifolds for cracks, adds leak checks of certain additional P/N fuel manifolds, and specifies replacement of the affected manifolds as an optional terminating action in lieu of the repetitive inspections. This AD results from reports of fire in the engine nacelle. We are issuing this AD to detect cracks in certain fuel manifolds and fuel leaks from other fuel manifolds, which could result in a fire in the engine nacelle and a hazard to the aircraft.
Extension of the Compliance Date for Cockpit Voice Recorder and Digital Flight Data Recorder Regulations
Document Number: 2010-31
Type: Proposed Rule
Date: 2010-01-07
Agency: Federal Aviation Administration, Department of Transportation
On March 7, 2008, the FAA published a final rule titled ``Revisions to Cockpit Voice Recorder and Digital Flight Data Recorder Regulations.'' The rule required certain upgrades of digital flight data recorder and cockpit voice recorder equipment on certain aircraft beginning April 7, 2010. The FAA is proposing to change that compliance date for some aircraft as outlined in this notice. This action follows petitions from several aircraft manufacturers and industry organizations indicating an inability to comply with the April 2010 requirement.
