Federal Aviation Administration August 18, 2006 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes Equipped With Rolls-Royce RB211-TRENT 800 Series Engines
Document Number: E6-13649
Type: Proposed Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This proposed AD would require revising the airplane flight manual to provide the flightcrew with new ground procedures for shedding core ice during long taxi periods in freezing fog. For airplanes unable to perform the shedding procedure after prolonged taxiing in freezing fog, this proposed AD would require certain investigative and corrective actions. This proposed AD results from reports of engine surges and internal engine damage due to ice accumulation during extended idle thrust operation in ground fog icing conditions. We are proposing this AD to prevent internal engine damage due to ice accumulation and shedding, which could cause a shutdown of both engines, and result in loss of control of the airplane.
Airworthiness Directives; Airbus Model A300 Airplanes
Document Number: E6-13647
Type: Proposed Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
Document Number: E6-13554
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA adopts a new airworthiness directive (AD) for all Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This AD requires you to do flight checks of the rigging of the engine and propeller systems. This AD results from a recent safety evaluation that used a data-driven approach to evaluate 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. We are issuing this AD to detect and correct improper adjustment of the flight idle fuel flow setting. This condition, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
Document Number: E6-13449
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135BJ airplanes. This AD requires inspecting for missing fire blocking material on the left- and right-hand partitions of the forward baggage compartment door; replacing the seal on both partitions; and performing corrective action if necessary. This AD results from a report indicating that certain airplanes were delivered with the fire blocking material missing and the seal improperly installed on the partitions of the forward baggage compartment door. We are issuing this AD to detect and correct such discrepancies on the forward baggage compartment partition, which, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin.
Airworthiness Directives; McDonnell Douglas Model MD-10-10F and MD-10-30F Airplanes and Model MD-11 and MD-11F Airplanes
Document Number: E6-13448
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model MD-11 series airplanes. That AD currently requires a revision of the airplane flight manual (AFM) to alert the flightcrew that both flight management computers (FMCs) must be installed and operational. That AD also requires an inspection to determine the serial number of the FMCs; and follow- on corrective actions, if necessary, which terminate the AFM revision. That AD also requires an inspection to verify if a certain modification is on the identification plates of the FMCs; and applicable follow-on and corrective actions. This new AD requires installation of upgraded FMC software, which would terminate the existing AD. This new AD also adds airplanes to the applicability, including adding Model MD-10-10F and MD-10-30F airplanes. This AD results from a report that the FMC does not acknowledge the pre-set glareshield control panel (GCP) altitude when profile (PROF) mode is engaged in descent mode. We are issuing this AD to prevent the un-commanded descent of an airplane below the selected level-off altitude, which could result in an unacceptable reduction in the separation between the airplane and nearby air traffic or terrain.
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
Document Number: E6-13445
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 airplanes. This AD requires inspecting to determine the part number of the twin motor actuators, and related investigative and corrective actions if necessary. This AD results from a report of a low pressure valve of the twin motor actuator found partially open, although the valve detection system indicated that the valve was closed. Investigation revealed that the locating pin in the actuator was too short to engage with the valve slot, resulting in incorrect alignment of the actuator and the drive assembly, causing the valve to remain partially open. We are issuing this AD to ensure that, in the event of an engine fire, the valve actuator functions properly to block the fuel flow to the engine and prevent an uncontrollable fire.
Airworthiness Directives; The Cessna Aircraft Company Models 172R, 172S, 182T, T182T, 206H, and T206H Airplanes
Document Number: E6-13442
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain The Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. This AD requires you to inspect the two end fittings on each of the flexible fuel hoses located in the engine compartment for the correct torque values, and, if any incorrect torque values are found during the inspection, tighten the hose end fittings to the correct torque values. This AD results from one report of loose fuel hose connections to the fuel injector servo on a Cessna Model 172S airplane. We are issuing this AD to detect and correct any incorrect torque values of the end fittings of flexible fuel hoses in the engine compartment, which could result in the loss of fuel flow and fuel leakage. Loss of fuel flow could result in partial or complete loss of engine power and fuel leakage could result in an engine compartment fire.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
Document Number: E6-13441
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA adopts a new airworthiness directive (AD) for all Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This AD requires you to incorporate power assurance charts into the Limitations Section of the Airplane Flight Manual (AFM), inspect the engine torque indication system, and recalibrate the torque pressure transducers as required. 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. We are issuing this AD to detect and correct torque transducers that are out of calibration. The above issue, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
Airworthiness Directives; Stemme GmbH & Co. KG Models S10, S10-V, and S10-VT Sailplanes
Document Number: E6-13440
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA adopts a new airworthiness directive (AD) for certain Stemme GmbH & Co. KG (Stemme) Models S10, S10-V, and S10-VT sailplanes. This AD requires you to inspect the connection between the aileron push-rod and the connecting shaft to determine if a safety washer is installed. If there is no safety washer installed, this AD requires you to modify the aileron control assembly. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent a loose bearing in the aileron control lever, which could result in separation of the aileron control system. Separation of the aileron control system could lead to loss of aileron control.
Airworthiness Directives; GROB-WERKE GMBH & CO KG Model G102 ASTIR CS Sailplanes
Document Number: E6-13439
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA supersedes Airworthiness Directive (AD) 84-09-05, which applies to certain GROB-WERKE GMBH & CO KG (previously identified as BURKHART-GROB FLUGZEUGBAU INDUSTRIESTRABE) Model G102 ASTIR CS sailplanes. AD 84-09-05 requires you to install a modified spherical locking bolt and nut in the forward horizontal stabilizer connection to the vertical stabilizer and install new locking pins in the aft connecting plate for the horizontal stabilizer. Since we issued AD 84- 09-05, fatigue cracks were found in the modified spherical locking bolt. Consequently, this AD requires you to replace the modified spherical locking bolt, the retaining pins (collar bolts), and associated hardware; add a life limit on the spherical locking bolt and the retaining pins; and repetitively inspect the front and rear horizontal stabilizer attachment. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent cracks in the spherical locking bolt, which could result in failure of the horizontal stabilizer connection. This failure could lead to loss of control.
Airworthiness Directives; General Electric Company (GE) CF6-80 Series Turbofan Engines
Document Number: E6-13437
Type: Rule
Date: 2006-08-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) for GE CF6-80 series turbofan engines with certain stage 1 high- pressure turbine (HPT) rotor disks. That AD currently requires an initial inspection as a qualification for the mandatory rework procedures for certain disks, and repetitive inspections only for certain disks for which the rework procedures were not required. That action also requires reworking certain disks before further flight, and removes certain CF6-80E1 series disks from service. This AD requires the same actions but shortens the compliance schedule for HPT disks that have not been previously inspected using AD 2004-04-07, which this AD supersedes. This AD results from a recent report of an uncontained failure of a stage 1 HPT disk. We are issuing this AD to detect and prevent cracks in the bottoms of the dovetail slots that could propagate to failure of the disk and cause an uncontained engine failure.
