Special Conditions: Gulfstream Aerospace Corporation Model G-1159 Gulfstream II Airplanes; High Intensity Radiated Fields (HIRF)
These special conditions are issued for the Gulfstream Aerospace Corporation Model G-1159 Gulfstream II airplanes modified by Gulfstream Aerospace Corporation, Dallas, Texas. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of dual electronic attitude direction indicators (ADI) and dual horizontal situation indicators (HSI). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high- intensity radiated fields (HIRF). These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that provided by the existing airworthiness standards.
Airworthiness Directives; Hamilton Sundstrand Model 14RF-19 Propellers
The FAA is superseding an existing airworthiness directive (AD) for Hamilton Sundstrand model 14RF-19 propellers. That AD currently requires replacing certain actuator yokes with improved actuator yokes. This AD requires the same actions. This AD results from the discovery of a part number (P/N) error in the applicability paragraph of AD 2006-12-19. We are issuing this AD to prevent actuator yoke arms breaking during flight, which could cause high propeller vibration and contribute to reduced controllability of the airplane.
Airworthiness Directives; Raytheon (Beech) Model 400 and 400A Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon (Beech) Model 400 and 400A series airplanes. This AD requires, among other actions, reviewing the airplane logbook to determine whether certain generator control unit (GCU) installation kits are installed, and replacing any incorrect GCU. This AD results from reports of over-voltage conditions of the direct current (DC) starter generator. We are issuing this AD to prevent such over-voltage conditions due to the incompatibility between certain GCUs, which could result in the loss of normal electrical power, damage to some electrical components, or blown fuses during flight, and consequent unrecoverable loss of some or all essential equipment.
Airworthiness Directives; Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. This AD requires modifying the wiring for the master dim and test system. For certain airplanes, this AD also requires related concurrent actions as necessary. This AD results from a report that the master dim and test system circuit does not have wiring separation of the test ground signal for redundant equipment in the flight compartment. We are issuing this AD to prevent a single fault failure in flight from simulating a test condition and showing test patterns instead of the selected radio frequencies on the communications panels, which could inhibit communication between the flightcrew and the control tower, affecting the continued safe flight of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplane models, that requires a one-time inspection for chafing or signs of arcing of the wire bundle for the auxiliary hydraulic pump, and other specified and corrective actions, as applicable. This AD also requires that, for certain airplanes, installation of additional protective sleeving on the upper portion of the auxiliary hydraulic pump wire assembly. This AD results from reports of shorted wires and evidence of arcing on the power cables of the auxiliary hydraulic pump, as well a fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent shorted wires or arcing at the auxiliary hydraulic pump, which could result in loss of auxiliary hydraulic power, or a fire in the wheel well of the airplane. The actions specified by this AD are also intended to reduce the potential of an ignition source adjacent to the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires modification of the wiring distribution of the alternating current bus transfer power system and the right-hand and left-hand windshield anti- icing system, as necessary. This AD results from a report of electrical sparks coming out of the flight deck from a panel behind the left seat. We are issuing this AD to prevent failure of the sliding window heating element(s), due to electrical overload, which could result in smoke and fire in the cockpit.
Airworthiness Directives; Raytheon Aircraft Company Models C90A, B200, B200C, B300, and B300C Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) (formerly Beech) Models C90A, B200, B200C, B300, and B300C airplanes. This proposed AD would require you to inspect the flight controls for improper assembly or damage, and if any improperly assembled or damaged flight controls are found, take corrective action. This proposed AD results from a report of inspections of several affected airplanes with improperly assembled or damaged flight controls. We are proposing this AD to detect and correct improperly assembled or damaged flight controls, which could result in an unsafe condition by reducing capabilities of the flight controls and lead to loss of control of the airplane.
Airworthiness Directives; Raytheon Aircraft Company Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) Airplanes
We propose to supersede Airworthiness Directive (AD) 62-24-01, which applies to all Raytheon Aircraft Company (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B45), and D45 (T-34B) airplanes. AD 62-24-01 currently requires you to repetitively inspect, using the dye penetrant method, the front and rear horizontal stabilizer spars for cracks and replace any cracked stabilizer. Since we issued AD 62-24-01, we determined that using dye penetrant inspection method may not detect cracks before failure of the horizontal stabilizer spars. Therefore, we are proposing to require the surface eddy current inspection method to detect cracks in the horizontal stabilizer spars. Consequently, this proposed AD would retain the actions required in AD 62-24-01 and change the required inspection method from dye penetrant to surface eddy current. We are proposing this AD to prevent failure of the front and rear horizontal stabilizer spars caused by fatigue cracks. This failure could result in stabilizer separation and loss of control of the airplane.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This proposed AD would require replacing the mini-latches on certain lavatory waste compartment doors with new, stronger latches, and other specified actions. This proposed AD results from reports of certain lavatory waste compartment doors opening during flight due to movement of the waste compartment during takeoff, because the mini-latches installed on the doors of those compartments lose their strength over time. We are proposing this AD to prevent the inability of the waste compartment doors to adequately contain a fire inside the lavatory waste compartment, and consequent uncontained fire and smoke within a lavatory during flight.
Airworthiness Directives; Eurocopter Canada Limited Model BO 105 LS A-3 Helicopters
This amendment adopts a new airworthiness directive (AD) for Eurocopter Canada Limited (Eurocopter) Model BO 105 LS A-3 helicopters that requires replacing certain fixed bolts and nuts, re-identifying certain main rotor nuts, and revising the Airworthiness Limitations Time Change Items (TCI) list to reflect the new life limits and new part numbers. This amendment is prompted by a re-evaluation of certain fatigue-critical parts, which resulted in establishing new life limits for certain like-numbered parts and re-identifying a certain existing part with a different part number, or in some cases, replacing them with new parts. The actions specified by this AD are intended to prevent fatigue failure of the fixed bolts and nuts, and subsequent loss of control of the helicopter.
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.

These special conditions are issued for the Piper PA 28-161 Cadet, Warrior II and Warrior III series airplanes, with the installation of a Thielert Aircraft Engines (TAE) Model TAE 125-1 aircraft diesel engine (ADE). These airplanes will have a novel or unusual design feature(s) associated with the installation of a diesel cycle engine utilizing turbine (jet) fuel. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for installation of this new technology engine. These 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.
Airworthiness Directives; McCauley Propeller Systems Propeller Models B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0
The FAA is adopting a new airworthiness directive (AD) for McCauley Propeller Systems propeller models B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/ L114HCA-0. This AD requires a onetime fluorescent penetrant inspection (FPI) and eddy current inspection (ECI) of propeller blades for cracks, and if any crack indications are found, removing the blade from service. This AD results from a report of two propeller blades on the same propeller assembly, found cracked during propeller overhaul. We are issuing this AD to detect cracks in the propeller blade that could cause failure and separation of the propeller blade and loss of control of the airplane.
Airworthiness Directives; Eurocopter France Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, N1, and SA-366G1 Helicopters
This amendment revises an existing airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, N1, and SA-366G1 helicopters that currently requires inspecting the main gearbox (MGB) base plate for a crack and replacing the MGB if a crack is found. This amendment increases the time intervals for inspecting the MGB base plate and includes minor editorial changes throughout the AD. This amendment is prompted by crack growth tests that indicate that the inspection intervals can be increased without affecting safety. The actions specified by this AD are intended to detect a crack in an MGB base plate and prevent failure of one of the MGB attachment points to the frame, which could result in severe vibration and subsequent loss of control of the helicopter.
Proposed Opinion on the Transferability of Interim Operating Authority Under the National Parks Air Tour Management Act
This action extends the comment period for a notice of proposed opinion that was published on June 28, 2006 (71 FR 36874). In that document, the FAA set forth a proposed decision on the transferability of interim operating authority under the National Parks Air Tour Management Act.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This proposed AD would require modifying the nose landing gear. This proposed AD results from reports of loss of the nose wheel assembly. We are proposing this AD to prevent the nose wheel nut from loosening, and consequently, the nose wheel assembly detaching from the airplane; and to prevent the nose wheel clamping loads from applying to the machined radius at the root of the stub axle, which could result in damage to the nose landing gear.
Airworthiness Directives; McDonnell Douglas Model DC-8-55, DC-8F-54, and DC-8F-55 Airplanes; and DC-8-60, DC-8-70, DC-8-60F, and DC-8-70F Series Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 airplanes. That proposed AD would have required a one-time inspection for cracks of the aft fuselage skin panel at the longeron 28 skin splice; repair of any cracks detected; and reporting of the findings of the inspection to the manufacturer. This new action revises the proposed AD by removing airplanes from the applicability; and adds repetitive inspections for cracks in the same area, a one-time inspection for previous repairs, and repair if necessary. This new action also would require reporting the inspection findings to the manufacturer, and would provide optional actions for extending the repetitive inspection intervals. The requirements proposed by this new action are intended to detect and correct cracks in the aft fuselage skin at the longeron 28 skin splice, which could lead to loss of structural integrity of the aft fuselage, resulting in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
Performance and Handling Qualities Requirements for Rotorcraft
The FAA is proposing new and revised airworthiness standards for normal and transport category rotorcraft due to technological advances in design and operational trends in normal and transport rotorcraft performance and handling qualities. The changes would enhance the safety standards for performance and handling qualities to reflect the evolution of rotorcraft capabilities.
Airworthiness Directives; Airbus Model A300 Airplanes; Model A310 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 airplanes and Model A310 airplanes, and for certain Airbus Model A300-600 series airplanes. This AD requires an inspection of the wing and center fuel tanks to determine if certain P-clips are installed and corrective action if necessary. This AD also requires an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary. This AD also requires installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P-clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.
Airworthiness Directives; Construcciones Aeronauticas, S.A. (CASA), Model C-212-CC Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain CASA Model C-212-CC airplanes. This AD restricts the operation of the airplane to carrying either passengers or cargo (but not both) in the same compartment, unless the airplane is modified to include an approved protective liner between the passengers and the cargo. This AD results from our determination that affected airplanes, when carrying both cargo and passengers in the same compartment, cannot achieve the required level of performance. We are issuing this AD to prevent a hazardous quantity of smoke, flames, and/or fire extinguishing agent from the cargo compartment from entering a compartment occupied by passengers or crew.

This proposed AD would require inspecting the fuel quantity indication system (FQIS) wire harness and the DC fuel pump wire harness to determine if the harnesses are properly attached at their respective attachment points and properly separated from one another, and performing corrective actions if necessary. This proposed AD results from a report that the FQIS wire harness may not be properly attached at its attachment points or properly separated from the DC fuel pump wire harness. We are proposing this AD to prevent chafing between those harnesses or chafing of the harnesses against adjacent airplane structure or components, which could present a potential ignition source that could result in a fire or explosion.
Airworthiness Directives; Airbus Model A310 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A310 airplanes. This proposed AD would require revising the Limitations section of the airplane flight manual by incorporating restrictions for high altitude operations. This proposed AD results from several incidents of pitch oscillations with high vertical loads that occurred during turbulence at high altitudes. We are proposing this AD to prevent pitch oscillations during turbulence, which could result in reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A310-200 and -300 Series Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Airbus Model A310-200 and -300 series airplanes. The proposed AD would have required repetitive inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door, and repair of any cracked or corroded part. The proposed AD also would have required repetitive inspections for cracks of the holes of the corner doublers, the fail-safe ring, and the door frames of the passenger/crew door structures. Since the proposed AD was issued, we have determined that that the proposed inspections and terminating action are essentially identical to those of another existing AD. Accordingly, the proposed AD is withdrawn.
Amendment to Class E Airspace; Kalispell, MT

Airworthiness Directives; Mitsubishi Heavy Industries, Ltd. MU-2B Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Mitsubishi Heavy Industries, Ltd. (MHI) MU-2B series airplanes. This AD requires you to incorporate text from the service information into the Limitations Section of the FAA-approved Airplane Flight Manual (AFM). This AD results from a recent safety evaluation that used a data-driven approach to analyze the design, operation, and maintenance of the MU-2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. Field reports indicate an unsafe condition of improper rigging and/or adjustment of the propeller feathering linkage. Service centers found the unsafe condition during inspections. We are issuing this AD to detect and correct improper rigging of the propeller feathering linkage. The above issue, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane.
Airworthiness Directives; Boeing Model 737-200, -300, and -400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-200, -300, and -400 series airplanes. This AD requires replacing the existing fueling float switch in the auxiliary fuel tank with a new, improved fueling float switch, installing a new liner system inside the float switch conduit, and performing related investigative and other specified actions. This AD results from reports of chafing of the direct-current-powered float switch wiring insulation in the center fuel tank. We are issuing this AD to prevent contamination of the fueling float switch of the auxiliary fuel tank by moisture or fuel, and chafing of the float switch wiring against the float switch conduit in the fuel tank, which could present an ignition source inside the fuel tank that could cause a fire or explosion.
Airworthiness Directives; Airbus Model A300 B2-203 and A300 B4-203 Airplanes; Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 series airplanes and all Model A300-600 and A310 series airplanes. That AD currently requires repetitive inspections of the pitch trim system to detect continuity defects in the autotrim function, and follow-on corrective actions if necessary. For certain airplanes, this new AD requires replacing the flight augmentation computers (FACs) with new improved FACs. This AD also revises the applicability of the existing AD. This AD results from the development of a final action intended to address the unsafe condition. We are issuing this AD to prevent a sudden change in pitch due to an out-of-trim condition combined with an autopilot disconnect, which could result in reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA is superseding two existing airworthiness directives (AD) that apply to certain Airbus Model A300 B2, A300 B4, and A300-600 series airplanes. One AD currently requires an inspection for cracks of the lower outboard flange of gantry No. 4 in the main landing gear (MLG) bay area, and repair if necessary. The other AD currently requires, among other actions, repetitive inspections of the gantry lower flanges, and repair if necessary. This new AD requires new repetitive inspections for cracks in the lower flange of certain gantries, and repair if necessary, which ends the existing inspection requirements. This new AD also provides for optional terminating actions for the new repetitive inspections. This AD results from a report of a large fatigue crack along the outboard flange of beam No. 4 and a subsequent determination that existing inspections are inadequate. We are issuing this AD to detect and correct fatigue cracks in the lower flanges of gantries 1 through 5 inclusive in the MLG bay area, which could result in reduced structural integrity of the fuselage, and consequent rapid decompression of the airplane.
Airworthiness Standards; Engine Bird Ingestion
The FAA is proposing to amend the aircraft turbine engine type certification standards to reflect recent analysis of the threat flocking birds present to turbine engine aircraft. These proposed changes would also harmonize FAA, Joint Aviation Authority (JAA), and European Aviation Safety Agency (EASA) bird ingestion standards for aircraft turbine engines type certificated by the United States and the JAA/EASA countries, and simplify airworthiness approvals for import and export. These proposed changes are necessary to establish uniform international standards that provide an adequate level of safety for aircraft turbine engines with respect to the current large flocking bird threat.
Public Notice for Waiver of Aeronautical Land-Use Assurance, Cambridge Municipal Airport, Cambridge, OH
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the release 4.105 acres of vacant airport property for an exchange of property between the Cambridge Area Regional Airport Authority and Dunning Investment Company, Ltd. The land was conveyed to the Cambridge Area Regional Airport Authority in Deed Volume 364, page 656 of the Recorder's Office, Guernsey County, Ohio. The land was acquired under FAA Project No. 3-39-0013-0303. There are no impacts to the airport by allowing the airport to dispose of the property. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. In exchange, the Cambridge Regional Airport Authority will receive a parcel of land adjacent to Cambridge Municipal Airport. This parcel is necessary to meet design standards for future airport development as indicated on the Airport Layout Plan for Cambridge Municipal Airport. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR Part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
Airworthiness Directives; Airbus Model A330, A340-200, and A340-300 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A330, A340-200, and A340-300 series airplanes. The existing AD currently requires repetitive inspections of a certain bracket that attaches the flight deck instrument panel to the airplane structure; replacement of the bracket with a new, improved bracket; and related investigative and corrective actions if necessary. This proposed AD would add a requirement for replacement of the existing bracket with a titanium- reinforced bracket, which would end the repetitive inspections in the existing AD. This proposed AD would also require related investigative and corrective actions while accomplishing the replacement, and would reduce the applicability in the existing AD. This proposed AD results from a report of cracking damage found on certain brackets that were replaced per the requirements in the existing AD. We are proposing this AD to prevent a cracked bracket. Failure of this bracket, combined with failure of the horizontal beam, could result in collapse of the left part of the flight deck instrument panel, and consequent reduced controllability of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. The existing AD currently requires a one-time inspection of the sliding members in the main landing gear (MLG) for cracking and replacement of the sliding members with serviceable parts if necessary. This proposed AD would require repetitive magnetic particle inspections of the sliding members of the MLG for cracking and corrective actions as necessary. This proposed AD results from inspection findings that have shown repetitive inspections are needed to establish fleet safety. We are proposing this AD to detect and correct fatigue cracking of the sliding member, which could result in possible separation of the MLG from the airplane and consequent reduced controllability of the airplane upon landing and possible injury to passengers.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes equipped with certain hydraulic accumulators. This proposed AD would require inspecting the hydraulic accumulators to identify certain serial numbers, and replacing any affected accumulator with a new or serviceable accumulator. Operators may delay doing the replacement by doing repetitive inspections of the affected hydraulic accumulators for signs of failure (leaking or cracking), and replacing any failed accumulator with a new or serviceable unit. This proposed AD results from a report that one hydraulic accumulator failed in service, which caused the loss of the yellow hydraulic system when the airplane was configured for landing. We are proposing this AD to prevent damage to the pressure skin, failure of certain hydraulic systems, contamination of the cabin with hydraulic mist, increased workload for the flightcrew associated with the loss of one or more hydraulic circuits, and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This proposed AD would require repetitive inspections for cracking of the wing skin, and related investigative/corrective actions if necessary. This proposed AD results from reports of cracks found in the lower wing skin originating at the forward tension bolt holes of the aft pitch load fitting. We are proposing this AD to detect and correct such cracking in the lower wing skin for the forward tension bolt holes at the aft pitch load fitting, which could result in a fuel leak and reduced structural integrity of the airplane.
