Airworthiness Directives; McDonnell Douglas Model DC-9-20, DC-9-30, DC-9-40, and DC-9-50 Series Airplanes; Model DC-9-14, DC-9-15, and DC-9-15F Airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) Airplanes; Model MD-88 Airplanes; and Model MD-90-30 Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain McDonnell Douglas transport category airplanes, that would have required an inspection of the upper lock link assembly of the nose landing gear (NLG) to determine the manufacturer, repetitive eddy current inspections for cracking, and modification or replacement if necessary. That proposal also would have provided for optional terminating action for the repetitive inspections. This new action revises the proposed rule by adding new airplanes to the applicability and adding related concurrent actions. The actions specified by this new proposed AD are intended to prevent fracture of the upper lock link assembly of the NLG, which could result in failure of the NLG to extend following a gear-down selection, and consequent gear-up landing, structural damage, and possible injury to passengers and crew. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Bombardier Model DHC-8-401 and -402 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-401 and -402 airplanes. This proposed AD would require a one-time inspection of the fuel and hydraulic tubes, and corrective actions if necessary. This proposed AD would also require modifying fairlead plate assemblies. This proposed AD is prompted by reports of chafing between fuel and hydraulic tubes and the fairlead plate where the tubes pass through the firewall. We are proposing this AD to prevent chafing of the fuel and hydraulic tubes, which could lead to fuel and/or hydraulic fluid leakage in the engine nacelle area and consequent fire or explosion.
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 cracks of the body skin, doubler, and bear strap at the forward edge of the upper and lower hinge cutouts of the forward entry door, related investigative actions, and corrective action if necessary. This proposed AD also would require a preventive modification. This proposed AD is prompted by reports of skin and bear strap cracks at hinge cutouts. We are proposing this AD to detect and correct cracks in the skin and bear strap at the hinge cutouts of the forward entry door, which could result in rapid decompression of the airplane.
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 Airplanes
The FAA proposes to revise an earlier proposed airworthiness directive (AD) that applies to all Pilatus Aircraft Ltd. (Pilatus) (also identified as Fairchild Republic Company and Fairchild Heli Porter) Model PC-6 airplanes. The earlier NPRM proposed to require you to repetitively inspect the stabilizer-trim attachment and structural components for cracks, corrosion, and discrepancies and replace any defective part with a new part. The earlier NPRM also proposed to require you to replace all Fairchild connecting pieces with a Pilatus connecting piece. The earlier NPRM resulted from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. This proposed AD would retain the actions from the earlier NPRM and would require you to replace fittings without an index after the part number (P/N) with an improved part. This proposed AD results from incorporating revised manufacture service information to include a procedure for replacing certain fittings with an improved part and to correct the allowable limits of the actuator attachment hole diameters. This proposed AD also clarifies the applicability. Since this action imposes an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this additional action.
Amendment to Class E Airspace; Wray, CO
This final rule will revise Class E airspace at Wray, CO. New Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) have been developed at Wray Municipal Airport. Additional Class E airspace extending upward from 700 feet above the surface is necessary for the safety of instrument flight rules (IFR) aircraft executing these new SIAPs and transitioning between the terminal and en route environment.
Federal Aviation Administration Flight Information Services (FIS) Policy Statement
This statement summarizes the major changes and the implications of publishing the revised policy, and background on the need for a revised policy. The revised FIS Policy updates the existing 1998 FAA Airborne FIS Policy to reflect the current FIS data link status and provides the basis for transition from the current (FAA) industry Flight Information Services Data Link (FISDL) service to the planned evolution of an FAA FIS data link service using National Airspace System (NAS) technologies such as the Universal Access Transceiver (UAT) and/or Next Generation Air-Ground Communication (NEXCOM). During the transition, the revised FIS Policy supports continuation of the FISDL service by temporarily extending the current use of VHF channels through FAA-industry agreement. In 1998 the FAA Administrator published the current Airborne Flight Information Services Policy Statement (see attachment). That policy provided the basis for implementing the existing FISDL service through FAA-industry agreement. Under the agreement, FAA provides two VHF frequencies and management oversight while industry (Honeywell) provides the FISDL network and cockpit products. In 2002 the FAA published the Automatic Dependent Surveillance-Broadcast (ADS-B) Link Decision which includes providing FIS-B services via the UAT network. The Safe Flight 21 program is developing the ADS-B technology and has intalled a ``pocket'' UAT network along the East Coast. The major purpose for publishing the revised FIS Policy is to establish a strategy for transitioning from the existing industry- government FIS data link service to one or more FAA-only FIS data link services. The existing industry-government service, called FIS Data Link (FISDL), is owned and operated by Honeywell Inc. The replacement FAA-only system(s) will be the Universal Access Transceiver (UAT) and/ or NEXCOM. During the transition to an FAA FIS data link service, the FAA will provide temporary extension of two VHF channels for continuation of the FISDL service.
Special Conditions; Tiger Aircraft, EFIS on the AG-5B; Protection of Systems for High Intensity Radiated Fields (HIRF)
These special conditions are issued to Tiger Aircraft, 266 Pilot Way, Martinsburg, WV, 25401, for a change to the Type Design of the Tiger AG-5B. This airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of an electronic flight instrument system (EFIS) in the form of a Garmin G1000 integrated avionics system. The current applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of the systems from the effects of high intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
Airworthiness Directives; GROB-WERKE Model G120A Airplanes
The FAA adopts a new airworthiness directive (AD) for all GROB-WERKE (GROB) Model G120A airplanes. This AD requires you to repetitively inspect the nose landing gear (NLG) assembly, paying special attention to the NLG swivel tube and the engine truss in the area of the NLG attachment, for cracks and damaged (defective) welding seams. If you find cracks or defects during any inspection, this AD requires you to replace the cracked or defective part. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct cracks and defects in the NLG assembly, which could result in failure of the NLG. This failure could lead to a hard landing and/or loss of control of the airplane during landing operations.
Airworthiness Directives; Cessna Aircraft Company Models 402C and 414A Airplanes
The FAA is adopting a new airworthiness directive (AD) to supersede AD 2005-05-52 (70 FR 13362, March 21, 2005), which applies to all Cessna Aircraft Company (Cessna) Models 402C and 414A airplanes. AD 2005-05-52 currently requires you to eddy current inspect the forward wing spars and visually inspect the aft and auxiliary spars. This AD is the result of fatigue and crack growth analyses of the wings of these airplanes, recent cracks found on Model 402C airplanes, and the FAA's determination that repetitive inspections and a wing spar modification are necessary to address the unsafe condition. Consequently, this AD would require repetitive eddy current inspections, visual inspections, and a spar strap modification on each wing. You must retain the actions of AD 2005-05-52 until you do the modifications of this AD. The actions specified by this AD are intended to prevent wing spar cap failure caused by undetected fatigue cracks. Such failure could result in loss of a wing with consequent loss of airplane control. FAA is also issuing AD 2005-12-12 to require the spar strap modification and long-term inspections on Models 401, 401A, 402, 402A, 402B, 411, and 411A airplanes.
Airworthiness Directives; Cessna Aircraft Company Models 401, 401A, 401B, 402, 402A, 402B, 411, and 411A Airplanes
The FAA is adopting a new airworthiness directive (AD) to supersede AD 79-10-15, which applies to all Cessna Aircraft Company (Cessna) Models 401, 401A, 401B, 402, 402A, 402B, 411, and 411A airplanes. AD 79-10-15 currently requires repetitive inspections of the right and left wing spar lower cap areas for fatigue cracks and requires wing spar cap repair or replacement as necessary. This AD is the result of fatigue and crack growth analyses of the wings of these airplanes, recent cracks found on similar design Model 402C airplanes, and the FAA's determination that repetitive inspections and a wing spar modification are necessary to address the unsafe condition. Consequently, this AD would require repetitive inspections and a spar strap modification on each wing. The actions specified by this AD are intended to prevent wing spar cap failure caused by undetected fatigue cracks. Such failure could result in loss of a wing with consequent loss of airplane control. FAA is also issuing AD 2005-12-13 to require the spar strap modification and long-term inspections on Models 402C and 414A airplanes.
Airworthiness Directives; Turbomeca S.A. Arrius 2 B1, 2 B1A, 2 B1A-1, and 2 B2 Turboshaft Engines
The FAA is adopting a new airworthiness directive (AD) for Turbomeca S.A. Arrius 2 B1, 2 B1A, 2 B1A-1, and 2 B2 turboshaft engines. This AD requires replacing the software in the Engine Electronic Control Unit (EECU). This AD results from a report of simultaneous loss of automatic control of both engines of a Eurocopter Deutschland EC 135 helicopter, during flight. We are issuing this AD to prevent simultaneous loss of automatic control of both engines and subsequent loss of control of the helicopter.
Airworthiness Directives; Teledyne Continental Motors (Formerly Bendix) S-20, S-1200, D-2000, and D-3000 Series Magnetos
The FAA is superseding an existing airworthiness directive (AD) for Teledyne Continental Motors (TCM) (formerly Bendix) S-20, S- 1200, D-2000, and D-3000 series magnetos equipped with impulse coupling assemblies. That AD currently requires replacing riveted-impulse coupling assemblies and snap-ring coupling assemblies, which are worn beyond limits, with serviceable riveted-impulse coupling assemblies or snap-ring impulse coupling assemblies. This ad requires a reduced inspection interval for magnetos with riveted-impulse coupling assemblies installed on certain Lycoming engine models. This AD does not lower the inspection interval for magnetos with snap-ring impulse coupling assemblies. This AD also limits the applicability to certain Lycoming engine models. This AD results from data provided by the manufacturer that shows a need to reduce the inspection intervals for riveted-impulse coupling assemblies used on certain Lycoming engine models. We are issuing this AD to prevent failure of the magneto impulse coupling assembly and possible engine failure.
Airworthiness Directives; Sikorsky Aircraft Corporation Model S-92A Helicopters
This amendment adopts a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This action requires replacing the main gearbox (MGB) lubrication/scavenge pump vespel spline adapters (vespel spline adapters) before further flight, and thereafter, replacing them at certain intervals. This amendment is prompted by a reported incident of an in-flight loss of oil pressure. The actions specified in this AD are intended to prevent loss of lubrication to the MGB, which could cause failure of one or both engine input drives, or planetary gear to sun gear tooth mesh failure, resulting in loss of power to the rotor system and subsequent loss of control of the helicopter.
Airworthiness Directives; Boeing Model 757-200, -200PF, and -200CB Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -200CB series airplanes. This AD requires repetitive inspections of the shim installation between the vertical flange and bulkhead. This AD is prompted by reports of cracks, loose and broken bolts, and shim migration in the joint between the aft torque bulkhead and the strut-to-diagonal brace fitting. We are issuing this AD to detect and correct such cracks, loose and broken bolts, and shim migration, which could result in damage to the strut and consequent separation of the strut and engine from the airplane.
Airworthiness Directives; Boeing Model 737-200, 737-300, 737-400, 737-500, 737-600, 737-700, 737-800, 737-900, 757-200, and 757-300 Series Airplanes; and McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F, DC-10-40, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain transport category airplanes. That AD currently requires modification of the reinforced flight deck door. This new AD expands the applicability of the existing AD and requires other actions related to the reinforced flight deck door. These other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. This AD is prompted by reports of discrepancies with the reinforced flight deck door. We are issuing this AD to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke or shrapnel, any of which could result in injury to the airplane flightcrew. This AD also requires finding and fixing wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.
