Electronic Signatures on Documents: Verigo, Incorporated (Verigo), Application for Exemption
The FMCSA announces that it has received from Verigo, Incorporated (Verigo) an application for an exemption from the signature requirement for a driver on the record of duty status (RODS). Verigo's application is being made on behalf of all drivers and carriers operating commercial motor vehicles in the U.S. and using the Verigo Wireless Logbook. The exemption would allow a signature entered on an electronic ``signature pad'' to be the functional equivalent of a handwritten signature on the RODS. Verigo states that this will allow the trucking industry to reduce administrative costs and increase productivity by providing a simple and effective alternative to paper RODS. The FMCSA requests public comment on Verigo's application for exemption.

Airworthiness Directives; Air Tractor, Inc. Models AT-400, AT-500, AT-600, and AT-800 Series Airplanes
We propose to supersede Airworthiness Directive (AD) 2007-13- 17, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-602, AT-802, and AT-802A airplanes. AD 2007-13-17 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2007-13-17, Air Tractor has learned of a Model AT-502B with a crack located where the lower engine mount tube is welded to the engine mount ring. In addition, Snow Engineering Co. has developed gussets that, when installed according to their service letter, terminate the repetitive inspection requirement. Consequently, this proposed AD would retain the inspection actions of AD 2007-13-17 for Model AT-602, AT-802, and AT-802A airplanes, including the compliance times and effective dates; establish new inspection actions for the AT- 400 and AT-500 series airplanes; incorporate a mandatory terminating action for all airplanes; and terminate the reporting requirement of AD 2007-13-17. We are proposing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.
Environmental Impact Statement: Christian, Shelby, Fayette, Marion, Clinton, Jefferson and Washington Counties, IL
The FHWA is issuing this notice to advise the public that an environmental impact statement will be prepared for a proposed highway project in Christian, Shelby, Fayette, Marion, Clinton, Jefferson, and Washington Counties, Illinois.
IFR Altitudes; Miscellaneous Amendments
This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
Proposed Establishment of Low Altitude Area Navigation Routes (T-Routes); St. Louis, MO
This action proposes to establish two low altitude Area Navigation (RNAV) routes, designated T-251 and T-272, in the St. Louis, MO, terminal area. T-routes are low altitude Air Traffic Service routes, based on RNAV, for use by aircraft that have instrument flight rules (IFR) approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is proposing this action to enhance safety and improve the efficient use of the navigable airspace in the St. Louis, MO, terminal area.
Proposed Modification of Class E Airspace; Hollister, CA
This action proposes to modify the Class E airspace area at Hollister, CA. Establishment of an Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Hollister Municipal Airport, Hollister, CA, has made this proposal necessary. Additional controlled airspace is needed for the safety and management of aircraft executing the new RNAV (GPS) SIAPs at Hollister Municipal Airport, Hollister, CA.

In accordance with the Paperwork Reduction Act of 1995, this notice announces the Maritime Administration's (MARAD's) intention to request extension of approval for three years of a currently approved information collection.
Canadian National Railway Company and Grand Trunk Corporation-Control-EJ&E West Company 1
The Surface Transportation Board (Board) is accepting for consideration the primary application filed October 30, 2007, by Canadian National Railway Corporation (CNR) and Grand Trunk Corporation (GTC), a noncarrier holding company through which CNR controls its U.S. rail subsidiaries, and seven related filings. The primary application seeks Board approval under 49 U.S.C. 11321-26 of the acquisition of control of EJ&E West Company (EJ&EW), a wholly owned noncarrier subsidiary of Elgin, Joliet and Eastern Railway Company (EJ&E), by CNR and GTC. This proposal is referred to as the Control Transaction, and CNR and GTC are referred to collectively as applicants. The related filings are notices of exemption involving an intra- corporate family transaction and the granting of trackage rights. The Sub-No. 1 filing provides for EJ&E to transfer property to EJ&EW, which, at that time, would become a rail common carrier, prior to applicants acquiring control of EJ&EW. The Sub-Nos. 2 through 7 filings provide for grants of trackage rights by EJ&EW to Grand Trunk Western Railroad (GTW), Illinois Central Railroad Company (IC), Chicago, Central & Pacific Railroad Company (CCP), and Wisconsin Central Ltd. (WCL), and by IC and CCP to EJ&EW, promptly upon applicants' acquisition of control of EJ&EW, should the Board approve the proposed Control Transaction. The Board finds that the Control Transaction is a ``minor transaction'' under 49 CFR 1180.2(c), and adopts a procedural schedule for consideration of the application. In finding that the transaction is a minor transaction, the Board has preliminarily determined that any anticompetitive effects of the transaction will clearly be outweighed by the transaction's anticipated contribution to the public interest in meeting significant transportation needs. 49 CFR 1180.2(b)(2). The Board makes this determination based solely on evidence presented in the application. The Board stresses that this is not a final determination, and its finding may be rebutted by filings and evidence submitted into the record for this proceeding. The Board will give careful consideration to any claims that the transaction will have anticompetitive effects that are not apparent from the application itself. Moreover, the Board has determined to prepare an Environmental Impact Statement (EIS) with respect to the transaction.
Canadian Pacific Railway Company, et al.-Control-Dakota, Minnesota & Eastern Railroad Corp., et al.
The Surface Transportation Board (Board) invites public comments on a proposed procedural schedule for this proceeding. On October 5, 2007, Canadian Pacific Railway Corporation (CPRC), Soo Line Holding Company, a Delaware Corporation and indirect subsidiary of CPRC (Soo Holding), Dakota, Minnesota & Eastern Railroad Corporation (DM&E), and Iowa, Chicago & Eastern Railroad Corporation, a wholly-owned rail subsidiary of DM&E (IC&E) (collectively referred to as the ``Applicants'') submitted a filing with the Board seeking approval under 49 U.S.C. 11321-26 of the acquisition of control of DM&E and IC&E by Soo Holding (and, indirectly, by CPRC). In Decision No. 2, served on November 2, 2007, and published in the Federal Register at 72 FR 63232- 36 on November 8, 2007, the Board accepted the October 5 submission as a prefiling notification, thus allowing the Applicants to perfect their application, and provide any supplemental materials or information, on or after December 5, 2007.\1\
Airworthiness Directives; Hartzell Propeller Inc. Model HC-E5N-3( ), HC-E5N-3( )(L), and HC-E5B-5( ) Propellers
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. Model HC-E5N-3( ), HC-E5N-3( )(L), and HC-E5B- 5( ) propellers. This AD requires a onetime eddy current inspection of the propeller hub mounting bolt holes and replacement of the propeller hub if cracked. This AD results from the discovery of a five-bladed propeller hub with a large crack on the mounting flange of the hub. We are issuing this AD to prevent propeller hub failure, blade separation, damage to the airplane, and possible loss of airplane control.
Airworthiness Directives; Cirrus Design Corporation Model SR22 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SR22 airplanes. This AD requires you to install a drain hole in the left and right outboard wing tips. This AD results from reports of pilots' inability to move the aileron control without using excessive force when flying in freezing conditions. Moisture from a prior rain shower entered through a gap at the interface of the left and right outboard wing tips and wing structure. The moisture traveled along the aft wing shear web, accumulated below the aileron control pulley, and froze at an altitude with an outside air temperature below freezing. When this moisture is exposed to freezing conditions, operation of the aileron control pulley is impaired. We are issuing this AD to prevent moisture from accumulating along the wing shear web where it may freeze in certain conditions. This condition could result in operational failure of the aileron control pulley, which could lead to loss of control.
Airworthiness Directives; Turbomeca Arriel 2S1 and 2S2 Turboshaft Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the European Aviation Safety Agency (EASA) to identify and correct an unsafe condition on Turbomeca Arriel 2S1 and 2S2 turboshaft engines. The MCAI states the following:
Airworthiness Directives; Rolls-Royce plc, RB211 Trent 768-60, 772-60, and 772B-60 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. That AD currently requires initial and repetitive on- wing or in-shop inspections of the high pressure/intermediate pressure (HP/IP) turbine bearing oil feed tube heat shield. This AD requires the same actions but introduces a terminating action to the repetitive inspections. This AD results from RR introducing a revised HP/IP turbine bearing support structure as terminating action to the repetitive inspections of the HP/IP turbine bearing oil feed tube heat shield. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane.
Airworthiness Directives; GROB-WERKE GMBH & CO KG Models G102 CLUB ASTIR III, G102 CLUB ASTIR IIIb, and G102 STANDARD ASTIR III Gliders
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:
Noise Compatibility Program Notice Baton Rouge Metropolitan Airport, Ryan Field, Baton Rouge, LA
The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Greater Baton Rouge Airport District under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On July 30, 2007, the FAA determined that the noise exposure maps submitted by the Greater Baton Rouge Airport District under part 150 were in compliance with applicable requirements. On November 13, 2007, the FAA approved the Baton Rouge Metropolitan Airport, Ryan Field noise compatibility program. Most of the recommendations of the program were approved. No program elements relating to new or revised flight procedures for noise abatement were proposed by the airport operator.
Airworthiness Directives; Boeing Model 777 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This proposed AD would require installing software upgrades to the airplane information management system (AIMS) located in the flight compartment. This proposed AD results from an investigation that revealed that detrimental effects could occur on certain AIMS software during flight. We are proposing this AD to prevent an unannunciated loss of cabin pressure. If an undetected loss of pressure event were to cause an unsafe pressure in the cabin, the flight crew could become incapacitated.

If granted, the exemptions would enable these individuals to qualify as drivers of commercial motor vehicles (CMVs) in interstate commerce without meeting the Federal vision standard.
Qualification of Drivers; Exemption Renewals; Vision
FMCSA previously announced its decision to renew the exemptions from the vision requirement in the Federal Motor Carrier Safety Regulations for 19 individuals. FMCSA has statutory authority to exempt individuals from the vision requirement if the exemptions granted will not compromise safety. The Agency has reviewed the comments submitted in response to the previous announcement and concluded that granting these exemptions will provide a level of safety that will be equivalent to, or greater than, the level of safety maintained without the exemptions for these commercial motor vehicle (CMV) drivers.
Agency Information Collection Activities; Revision of an Approved Information Collection: Motor Carrier Safety Assistance Program
In accordance with the Paperwork Reduction Act of 1995, FMCSA announces its plan to submit the Information Collection Request (ICR) described below to the Office of Management and Budget (OMB) for review and approval. This information collection consists of grant application preparation, quarterly reports and electronic data documenting the results of driver/vehicle inspections performed by the States. On September 21, 2007, FMCSA published a Federal Register notice allowing for a 60-day comment period on the ICR. One comment was received.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This rule amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes in the National Airspace System, such as the commissioning of new navigational facilities, adding of 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; General Electric Company (GE) CF6-80C2B1 Turbofan Engine
The FAA is adopting a new airworthiness directive (AD) for a GE CF6-80C2B1 turbofan engine, serial number (SN) 690203, with fan disk, part number (P/N) 1703M78P11, SN RPMDA662, installed. This AD requires stripping of thermal spray coating, inspection of dovetail slots, and reapplication of thermal spray coating on certain stage 1 fan disks. This AD results from a report that a repair shop did not meet the process requirements when applying copper-nickel-indium (Cu- Ni-In) thermal coating to certain stage 1 fan disks. We are issuing this AD to prevent possible uncontained release of multiple fan blades, resulting in damage to the airplane.
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 767 airplanes. That AD currently requires repetitive measurements of the rudder and elevator freeplay, repetitive lubrications of rudder and elevator components, and related investigative/corrective actions if necessary. This new AD instead requires revised repetitive measurements of the rudder freeplay and the elevator freeplay for each of the power control actuators (PCAs) that move the rudder and elevator, corrective and related investigative actions if necessary, and repetitive lubrications of the rudder and elevator components. For some airplanes, this AD also requires related concurrent actions. This AD results from reports of freeplay-induced vibration of the rudder and the elevator. The potential for vibration of the control surface should be avoided because the point of transition from vibration to divergent flutter is unknown. We are issuing this AD to prevent excessive vibration of the airframe during flight, which could result in loss of control of the airplane.
Airworthiness Directives; Societe de Motorisations Aeronautiques (SMA) SR305-230 and SR305-230-1 Reciprocating Engines
We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the European Aviation Safety Agency (EASA) to identify and correct an unsafe condition on SMA SR305-230 and SR305-230-1 reciprocating engines. The MCAI states the following:
Airworthiness Directives; Rolls-Royce Corporation AE 3007A and AE 3007C Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C series turbofan engines. That AD currently prohibits any flight following a ground engine start where the engine oil temperature is below 32 [deg]F (0 [deg]C), unless certain preflight operational procedures are followed. This AD also requires those actions and would also require a terminating action. This AD results from design improvements to components in the accessory gearbox air turbine starter mounting pad. We are issuing this AD to prevent an in-flight engine shutdown due to loss of engine oil from the engine accessory gearbox starter pad shaft seal drain and possible loss of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER, -135KE, -135KL, and -135LR Airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Hawker Beechcraft Model 400A Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Model 400A series airplanes. This AD requires inspecting the galley cabinets to determine if a certain part number is installed or if a certain size of wire already exists, and doing related investigative/corrective actions if necessary. This AD results from reports of undersized, and consequently unprotected, wire in the galley cabinets. We are issuing this AD to prevent overheating of wire insulation and consequent fire or smoke in the airplane cabin.
Environmental Impact Statement: Sitka Rocky Gutierrez Airport, Sitka, AK
The Federal Aviation Administration announces that it will be including the assessment of the transfer of lands from federal to state ownership for aviation uses within the Environmental Impact Statement (EIS) currently being prepared by the Federal Aviation Administration. Public and Agency Scoping comments are being sought by the Federal Aviation Administration to receive input regarding the assessment of this additional proposed project within the EIS. Responsible Official: Patricia A. Sullivan, Environmental Protection Specialist, Federal Aviation Administration, Alaskan Region, Airports Division, 222 W. 7th Avenue, 14, Anchorage, AK 99513- 7587, Telephone (907) 271-5454.
Agency Information Collection Activity Seeking OMB Approval
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 August 15, 2007, vol. 72, no. 157, page 45862-45863. Feedback from this survey is used in the prevention of runway collisions and in the Department of the severity and frequency of runway incursions.
Special Conditions: Boeing Model 757 Series Airplanes; Seats With Non-Traditional, Large, Non-Metallic Panels
This action proposes special conditions for Boeing Model 757 series airplanes. These airplanes, as modified by Triad International Maintenance Company (TIMCO), will have a novel or unusual design feature(s) associated with seats that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Reports, Forms and Record Keeping Requirements Agency Information Collection Activity Under OMB Review
In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501, et seq.), this notice announces that the Information Collection Request (ICR) abstracted regarding the Uniform Tire Quality Grading Standard (UTQGS) below has been forwarded to the Office of Management and Budget (OMB) for review and comment. The ICR describes the nature of the information collections and their expected burden. The Federal Register Notice with a 60-day comment period was published on July 20, 2007 [72 FR 39889-39890].
Nationality and Registration Marks; Non Fixed-Wing Aircraft
This action confirms the direct final rule issued on September 14, 2007, which became effective on November 13, 2007. The rule changes certain display requirements for nationality and registration marks for powered parachutes and weight-shift-control aircraft. No comments were received on this direct final rule.
Airworthiness Directives; British Aerospace Aircraft Group, Scottish Division, Model Beagle B.121 Series 1, 2, 3 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Eclipse Aviation Corporation Model EA500 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Eclipse Aviation Corporation Model (Eclipse) EA500 airplanes. This AD requires you to inspect the fuel filler adapters for primer and/or paint in the surround and, if present, remove the primer and/or paint. This AD results from an observation during a factory walk-around that the fuel filler surround was primed instead of being bare metal. We are issuing this AD to inspect and, if necessary, remove any paint and/or primer to restore the fuel filler adapter lightning strike protection. A lightning strike on the filler cap with insulating primer on the surround could result in the strike not dissipating to the surround. This could lead to arcing and ignition of fuel vapor inside the fuel tank.
Airworthiness Directives; Alpha Aviation Design Limited Model R2160 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 distortion of the rudder bars due to rudder control forces during aerobatic operation and nose wheel steering reaction forces. Rudder bar distortion could result in reduced control or loss of control. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Ferrari S.p.A. and Ferrari North America; Receipt of Application for a Temporary Exemption From the Advanced Air Bag Requirements of FMVSS No. 208
In accordance with the procedures in 49 CFR Part 555, Ferrari S.P.A. and Ferrari North America (collectively, ``Ferrari'') have petitioned the agency for a temporary exemption from certain advanced air bag requirements of FMVSS No. 208. The basis for the application is that compliance would cause substantial economic hardship to a manufacturer that has tried in good faith to comply with the standard. This notice of receipt of an application for temporary exemption is published in accordance with the statutory provisions of 49 U.S.C. 30113(b)(2). NHTSA has made no judgment on the merits of the application.
Airworthiness Directives; Boeing Model 727 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This proposed AD would require repetitive inspections for cracking or corrosion of the threaded end of the lower segment of the main landing gear (MLG) side strut, and corrective actions if necessary. This proposed AD also would require prior or concurrent inspection for cracking or corrosion of the threads and thread relief area of the lower segment, corrective action if necessary, and re-assembly using corrosion inhibiting compound. This proposed AD results from reports of the threads cracking on the MLG side strut lower segment. We are proposing this AD to prevent a fractured side strut, which could result in collapse of the MLG.
Airworthiness Directives; Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections for fatigue cracking in the longitudinal floor beam web, upper chord, and lower chord located at certain body stations, and repair if necessary. This proposed AD results from several reports of cracks in the center wing box longitudinal floor beams, upper chord, and lower chord. We are proposing this AD to detect and correct fatigue cracking of the upper and lower chords and web of the longitudinal floor beams, which could result in rapid loss of cabin pressure.
Airworthiness Directives; Boeing Model 737-200 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-200 series airplanes. This proposed AD would require repetitive inspections to detect cracking of the support fittings of the Krueger flap actuators, and corrective actions if necessary. This proposed AD also would require eventual replacement of any existing aluminum support fitting on each wing with a steel fitting, and modification of the aft attachment of the actuator. Doing these actions would terminate the repetitive inspection requirements. This proposed AD results from reports of cracking due to fatigue and stress corrosion of the support fittings of the Krueger flap actuator. We are proposing this AD to prevent cracking of the support fittings, which could result in fracturing of the actuator attach lugs, separation of the actuator from the support fitting, severing of the hydraulic lines, resultant loss of hydraulic fluids, and consequent reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. The existing AD currently requires an accelerated schedule of repetitive testing of the elevator servo control loops, and corrective actions if necessary. This proposed AD would retain the existing requirements, reduce the applicability of the existing AD, and add terminating actions. This proposed AD results from reports of failed elevator servo controls due to broken guides. We are proposing this AD to prevent failure of the elevator servo controls during certain phases of takeoff, which could result in an unannounced loss of elevator control and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 757 Airplanes Equipped with Rolls Royce RB211-535E Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757 airplanes equipped with Rolls Royce RB211- 535E engines. This proposed AD would require repetitive inspections for signs of damage of the aft hinge fittings and attachment bolts of the thrust reversers, and related investigative and corrective actions if necessary. This proposed AD results from reports of several incidents of bolt failure at the aft hinge fittings of the thrust reversers due to, among other things, high operational loads. We are proposing this AD to prevent failure of the attachment bolts and consequent separation of a thrust reverser from the airplane during flight, which could result in structural damage to the airplane.
Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections for cracking of the body buttock line (BBL) 0.07 floor beam between body station (BS) 651 and BS 676 and between BS 698 and BS 717, and related investigative and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections. This proposed AD results from reports of cracking in the BBL 0.07 floor beam. We are proposing this AD to prevent failure of the main deck floor beams at certain body stations due to fatigue cracking, which could result in rapid decompression of the airplane.
