Federal Aviation Administration July 2005 – Federal Register Recent Federal Regulation Documents

This action corrects a final rule published in the Federal Register on March 14, 2005 (70 FR 12414). In that rule, the effective date was inadvertently published as September 29, 2005. The correct effective date is September 1, 2005. This action corrects that error.

The FAA proposes to adopt a new airworthiness directive (AD) for certain SOCATAGroupe AEROSPATIALE (SOCATA) Model TBM 700 airplanes. This proposed AD would require you to inspect the fuselage skin in the VHF1 antenna mounting area for cracks and loose rivets. This proposed AD would also require you to modify the area if you find cracks or loose rivets. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this proposed AD to detect and correct cracks in the fuselage skin, which could result in loss of aircraft pressurization. Loss of aircraft pressurization could lead to flight crew incapacitation.

The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.

In compliance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the FAA invites public comment on one public information collection which will be submitted to OMB for review and approval.

This document proposes adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 47D1, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A and Coastal Helicopters, Inc. Model OH-13H (Tomcat Mark 5A, 6B, 6C) helicopters that have a certain scissors assembly or weld assembly scissors bracket installed. The AD would require, within 60 days, determining and recording the total hours time-in-service (TIS) for each Parts Manufacturer Approval (PMA)-produced scissors assembly and weld assembly scissors bracket and would establish a life limit for each affected part. This proposal is prompted by the need to establish a life limit on scissors assemblies and weld assembly scissors brackets produced under PMA No. PQ808SW or installed per Supplemental Type Certificate (STC) No. SH2772SW. The actions specified by the proposed AD are intended to establish a life limit to prevent using a scissors assembly or weld assembly scissors bracket past its life limit, which could result in failure of the part and subsequent loss of control of the helicopter.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires applying an anti-static conductive coating to the fuel access and thermal anti-icing blowout doors at the location of the bonding fasteners on the leading edge of the wings, and performing a resistance test on the new coating to ensure correct ground path resistance. This AD is prompted by a report that an anti-static coating was not applied correctly on doors located within a flammable fluid leakage zone. We are issuing this AD to prevent an uncontrollable fire in the leading edge of the wing, which could damage critical wing structures and cause a fuel tank explosion.

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 757 airplanes. The original NPRM would have required inspections of certain wire bundles in the left and right engine-to-wing aft fairings for discrepancies, and related investigative and corrective actions if necessary. The original NPRM was prompted by a report indicating that a circuit breaker for the fuel shutoff valve tripped due to a wire that chafed against the structure in the flammable leakage zone of the aft fairing, causing a short circuit. This action revises the original NPRM by adding a new requirement for installing back-to-back p-clamps between the wire and hydraulic supply tube at the aft end of the right-hand strut only; and associated re-routing of the wire bundles, if necessary; and adding airplanes to the applicability. This action also clarifies the applicability specified in the original NPRM. We are proposing this supplemental NPRM to prevent chafing between the wire bundle and the structure of the aft fairing, which could result in electrical arcing and subsequent ignition of flammable vapors and possible uncontrollable fire.

This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 and EMB-135 series airplanes, that requires replacement of the engine-driven hydraulic pump. This action is necessary to prevent engine oil leakage at the coupling seal between the hydraulic pump and the engine gearbox from causing low engine oil levels, which could lead to in-flight engine shutdown and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Model 767-400ER series airplanes; and Model 777-200 and - 300 series airplanes. This proposed AD would require, for certain airplanes, repetitive testing of the fill and safety fittings of the fire extinguishing bottles in the forward cargo compartment for leaks; and repetitive application of a corrosion inhibiting compound (CIC) or replacement of the fire extinguishing bottles with reworked fire extinguishing bottles, as necessary. For all airplanes, this proposed AD would require replacement of the fire extinguishing bottles with reworked fire extinguishing bottles, which would end the repetitive tests and CIC applications if applicable. This proposed AD is prompted by failure of the safety fittings for the fire extinguishing bottles. We are proposing this AD to prevent failure of the safety fittings for the fire extinguishing bottles due to corrosion, which could result in leakage of extinguishing agent. If a fire occurs in the cargo bay, the fire extinguishing bottles could have less than enough extinguishing agent to control a fire.

The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) models BR700-710A1-10 and BR700-710A2-20 turbofan engines. That AD currently requires initial and repetitive visual and ultrasonic inspections of fan discs, part numbers (P/Ns) BRR18803, BRR19248, and BRR20791 for cracks, and if necessary, replacement with serviceable parts. This proposed AD would require the same inspections of these fan discs, with certain old design P/N fan blades installed. This proposed AD would extend the inspection interval for certain fan discs having new design P/N fan blades installed. Also, this proposed AD would add as optional terminating action to the repetitive inspections, installation of certain P/N new fan discs, certain P/N new fan blades, and engine fan speed (N1) Keep Out Zone software. This proposed AD results from a revised RRD service bulletin (SB) that introduces relaxed inspection intervals for certain P/N combinations of fan discs and fan blades, and introduces improved design fan discs and fan blades. We are proposing this AD to detect and prevent cracks in the fan disc that could result in an uncontained engine failure and damage to the airplane.

The FAA is adopting a new noise standard for subsonic jet airplanes and subsonic transport category large airplanes. This noise standard ensures that the latest available noise reduction technology is incorporated into new aircraft designs. This noise standard, Stage 4, applies to any person submitting an application for a new airplane type design on and after January 1, 2006. The standard may be chosen voluntarily prior to that date. This noise standard is intended to provide uniform noise certification standards for Stage 4 airplanes certificated in the United States and those airplanes that meet the new International Civil Aviation Organization Annex 16 Chapter 4 noise standard.

The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, 25F, 28, 29, 31, 31A, 35, 35A (C- 21A), and 36 airplanes. This AD requires a one-time inspection of the center ball of the aileron control cable or cables for a defective swage, and corrective actions if necessary. This AD is prompted by a report indicating that an aileron cable failed on one affected airplane when the cable underwent a tension check. We are issuing this AD to prevent severe weakening of the aileron cable, and consequent reduced controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires repetitive inspections for damage of the drive rod assembly of the aileron tab on each aileron actuator; repetitive measurements of the clearance between the aileron hydraulic lines and the drive rod; and related investigative and corrective actions if necessary. This AD is prompted by a report of an aileron 2 fault caused by severe wear of the polyamide washer that is part of an anti-rotation bush assembly in the aileron attachment lug. We are issuing this AD to prevent excessive wear of the polyamide washer of the aileron actuator bush assembly, which could result in aileron flutter and loss of control of the airplane.

This action proposes to establish seven Area Navigation Instrument Flight Rules Terminal Transition Routes (RITTR) in the Jacksonville, FL, terminal area. RITTRs are low altitude Air Traffic Service routes, based on Area Navigation (RNAV), for use by aircraft having instrument flight rules (IFR)-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The purpose of RITTR is to expedite the handling of IFR overflight aircraft through busy terminal airspace areas. The FAA is proposing this action to enhance the safe and efficient use of the navigable airspace in the Jacksonville, FL, terminal area.

This document proposes to modify Class E airspace at Akron, OH. An Airship RNAV Global Positioning System 263[deg] Standard Instrument Approach Procedure has been developed for Wingfoot Lake Airship Operations Airport, Akron Suffield, OH. Controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing this approach. This action would increase the area of the existing controlled airspace for Akron, OH.

This document proposes to modify Class E airspace at Madison, IN. Standard Instrument Approach Procedures have been developed for Madison Municipal Airport, Madison, IN. Controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing these approach procedures. This action would increase the area of existing controlled airspace for Madison, IN.
