Airworthiness Directives; Rolls-Royce plc RB211 Trent 800 Series Turbofan Engines
Document Number: E6-5666
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Aviation Administration, Department of Transportation
This action withdraws a notice of proposed rulemaking (NPRM). That NPRM proposed to revise the existing airworthiness directive (AD) applicable to Rolls-Royce plc (RR) Model RB211 Trent 892, 884, 877, 875, and 892B series turbofan engines. That proposed rule would have required initial and repetitive inspections of the angled drive upper shroud, the intermediate gearbox housing (IGH), and the external gearbox lower bevel box (LBB) housing, and initial and repetitive master magnetic chip detector (MCD) inspections. Since we issued that proposed rule, RR notified us that after reviewing the service experience and the original actions taken, the unsafe condition no longer exists and mandatory actions required by the proposed rule are no longer required. Accordingly, we withdraw the proposed rule.
Airworthiness Directives; Turbomeca Arriel 1B, 1D, 1D1, and 1S1 Turboshaft Engines
Document Number: E6-5646
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to revise an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD currently requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD also currently requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. This proposed AD revision would require the same actions, but would relax the compliance times for initially replacing 2nd stage turbines in Arriel 1B, 1D, and 1D1 turboshaft engines. This proposed AD revision results from a request by Turbomeca to clarify the compliance times for 2nd stage turbine initial replacement on Arriel 1D, 1D1, and 1B turboshaft engines. We are proposing this AD revision to clarify and relax the AD compliance times for 2nd stage turbine initial replacement on Arriel 1B, 1D, and 1D1 turboshaft engines. We are also proposing this AD revision to prevent inflight engine shutdown and subsequent forced autorotation landing or accident.
Airworthiness Directives; General Electric Company CF6-50C Series Turbofan Engines
Document Number: E6-5645
Type: Proposed Rule
Date: 2006-04-17
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-50C series turbofan engines. This proposed AD would require reworking the forward fan stator case and installing a fan module secondary containment shield. This proposed AD results from reports of uncontained fan blade failures causing damage and separation of airplane hydraulic lines. We are proposing this AD to prevent uncontained fan blade failures, which can result in separation of airplane hydraulic lines, damage to critical airplane systems, and possible loss of airplane control.

Type: Proposed Rule
Date: 2006-04-13
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend Control 1234L, Offshore Airspace Area in Alaska. Specifically, this action proposes to modify Control 1234L in the immediate vicinity of the Saint Paul Island Airport, AK, by lowering the airspace floor from 2,000 feet above ground level (AGL) to 700 AGL. Additionally, outside the vicinity of the airport this proposal lowers the airspace floor from 2,000 AGL to 1,200 feet AGL within a 73-mile radius of the St. Paul Island Airport. The FAA is proposing this action to provide additional controlled airspace for aircraft instrument operations (IFR) at the St. Paul Island Airport.
Airworthiness Directives; Airbus Model A319, A320, and A321 Airplanes
Document Number: E6-5476
Type: Proposed Rule
Date: 2006-04-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This proposed AD would require a detailed inspection for cracks and marks on the carbon blades of the ram air turbine (RAT), and replacement of the RAT with a new or serviceable RAT if necessary. This proposed AD results from a report of three chord-wise cracks on the aft side of one carbon blade of a certain RAT. We are proposing this AD to detect and correct cracks and/or marks on the RAT carbon blades, which could result in reduced structural integrity of the carbon blade, and consequent loss of the RAT as a source of hydraulic and electrical power in an emergency.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145XR Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-145XR airplanes. This proposed AD would require replacement of certain segments of the passenger seat tracks with new, improved seat tracks. This proposed AD results from instances where the shear plungers of the passenger seat legs were not adequately fastened. We are proposing this AD to prevent inadequate fastening of the seat leg shear plungers, which could result in failure of the passenger seat tracks during emergency landing conditions and consequent injury to passengers.
Airworthiness Directives; Boeing Model 737-100, -200, and -200C Series Airplanes
Document Number: E6-5469
Type: Proposed Rule
Date: 2006-04-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 737 series airplanes. The existing AD currently requires inspection of the elevator tab inboard hinge support structure to detect fatigue cracking and corrective action if necessary. That AD also provides an optional terminating action. This proposed AD would add airplanes to the applicability and would require new repetitive inspections. For airplanes having elevators with laminated rear spars, this proposed AD would require repetitive inspections for interlaminar corrosion, delamination, or disbonding in the rear spar, repetitive inspections for cracking in the spar web, and repair including related investigative/corrective actions if necessary. For airplanes having elevators with solid rear spars, this proposed AD would require repetitive inspections for cracking in the spar web and repair including related investigative/corrective actions if necessary. This proposed AD results from reports of cracks in the elevator rear spar web at the tab hinge bracket locations. We are proposing this AD to detect and correct cracking, corrosion, interlaminar corrosion, delamination, and disbonding in the elevator rear spar, which may reduce elevator stiffness and lead to in-flight vibration. In-flight vibration may lead to elevator and horizontal stabilizer damage and reduced controllability of the airplane.

Airworthiness Directives; Gulfstream Model GIV-X and GV-SP Series Airplanes
Document Number: 06-3540
Type: Rule
Date: 2006-04-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an existing airworthiness directive (AD), which applies to certain Gulfstream Model GIV-X and GV-SP series airplanes. That AD currently requires revising the Limitations section of the airplane flight manual (AFM) by incorporating new procedures to follow in the event that the cockpit displays go blank or malfunction. This AD allows for the use of alternative AFM revisions for a certain subset of the existing applicability. This AD results from a report that all four of the cockpit flight panel display units simultaneously went blank during flight. We are issuing this AD to ensure that the flightcrew is advised of the appropriate procedures to follow in the event that the cockpit displays go blank or malfunction, which could result in a reduction of the flightcrew's situational awareness and possible loss of control of the airplane.

Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Sicma Aero Seat (formerly Farner) cabin attendant seats series 150 type FN and series 151 type WN. This AD requires installing two protection fairings over the upper seat structure to cover the gap between the upper and lower seats and prevent any contact with the bottom seat folding mechanisms. This AD results from a child catching its fingers in the folding mechanism of the bottom of the attendant seat. We are issuing this AD to prevent injury resulting from contact with the bottom folding mechanism.
Airworthiness Directives; Boeing Model 767 Airplanes
Document Number: 06-3478
Type: Rule
Date: 2006-04-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This AD requires performing a test of the bonding resistance between the engine fuel feed tube fitting and the front spar, applying sealant on a hex nut inside the dry bay, and performing any applicable corrective actions. This AD results from a report that the engine fuel feed tubes were found not electrically bonded to the front spar. We are issuing this AD to prevent an ignition source from entering the fuel tank during a lightning strike event, which could cause a fuel tank explosion.
Airworthiness Directives; Short Brothers Model SD3 Airplanes
Document Number: E6-5357
Type: Proposed Rule
Date: 2006-04-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Short Brothers Model SD3 airplanes. The original NPRM would have required installing additional fuel tank bonding jumpers, performing an in-place resistance check of the float switches, inspecting certain internal components of the fuel tanks, and performing related corrective actions if necessary. The original NPRM would have also required revisions to the Airworthiness Limitations section of the Instructions for Continued Airworthiness, and to the airplane flight manual procedures for operation during icing conditions and fuel system failures. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by adding service information. We are proposing this supplemental NPRM to prevent ignition sources inside the fuel tanks, which could lead to fire or explosion.
Airworthiness Directives; Boeing Model 747-200C and -200F Series Airplanes
Document Number: 06-3432
Type: Rule
Date: 2006-04-12
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747-200C and -200F series airplanes. That AD currently requires repetitive inspections to find fatigue cracking in the upper chord of the upper deck floor beams, and repair if necessary. For certain airplanes, the existing AD also provides an optional repair/modification, which extends certain repetitive inspection intervals. This new AD reduces the compliance time for all initial inspections and reduces the repetitive interval for a certain inspection. This AD results from new reports of cracks in the upper deck floor beams occurring at lower flight cycles. We are issuing this AD to find and fix cracking in certain upper deck floor beams. Such cracking could extend and sever floor beams at a floor panel attachment hole location and could result in rapid decompression and loss of controllability of the airplane.
Fire Penetration Resistance of Thermal Acoustic Insulation Installed on Transport Category Airplanes
Document Number: E6-5330
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
This document makes a correction to the Notice of Proposed Rulemaking (NPRM) published in the Federal Register on April 3, 2006 by changing the amendment number to a notice number. The NPRM proposed to extend, by 12 months, the date for operators to comply with the fire penetration resistance requirements of thermal/acoustic insulation used in transport category airplanes manufactured after September 2, 2007.
Airworthiness Directives; Gulfstream Model GV-SP Series Airplanes
Document Number: E6-5253
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Gulfstream Model GV-SP series airplanes. The proposed AD would have required an inspection to determine the serial number of the anti-skid control unit (ACU) in the right electronics equipment rack, and replacement of the ACU with a new or serviceable ACU if necessary. Since the proposed AD was issued, we have received new data that indicate the identified unsafe condition has been corrected on all airplanes that would have been affected by the NPRM, and on all ACUs in the affected range of serial numbers. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; Airbus Model A300 F4-600R Series Airplanes and Model A300 C4-605R Variant F Airplanes
Document Number: E6-5246
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 F4-600R series airplanes and Model A300 C4-605R Variant F airplanes. This proposed AD would require modifying certain structure in the fuselage zone at the lavatory venturi installation in the nose section, and performing a related investigative action and corrective action if necessary. This proposed AD results from an analysis that revealed that airplanes equipped with Airbus Modification 08909 had a concentration of loads higher than expected in the fuselage zone (high stress) at the lavatory venturi installation in the nose section, which could be the origin of cracks that developed in the fuselage skin and propagated from the edge of the air vent hole. We are proposing this AD to prevent fatigue cracking of the fuselage skin, which could result in loss of the structural integrity of the fuselage and consequent rapid depressurization of the airplane.
Special Conditions: Airbus Model A380-800 Airplane, Reinforced Flightdeck Bulkhead
Document Number: E6-5240
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
This notice proposes special conditions for the Airbus A380- 800 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. Many of these novel or unusual design features are associated with the complex systems and the configuration of the airplane, including its full- length double deck. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards regarding a reinforced flightdeck bulkhead. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish an appropriate level of safety for a reinforced flightdeck bulkhead and are equivalent to the standards established by existing airworthiness regulations for the flightdeck door. Additional special conditions will be issued for other novel or unusual design features of the Airbus Model A380-800 airplane.
Safety Standards for Flight Guidance Systems
Document Number: 06-3467
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
This action amends the airworthiness standards for new designs and significant product changes for transport category airplanes concerning flight guidance systems. The standards address the performance, safety, failure protection, alerting, and basic annunciation of these systems. This rule is necessary to address flight guidance system vulnerabilities and to consolidate and standardize regulations for functions within those systems. In addition, this rule updates the current regulations regarding the latest technology and functionality. Adopting this rule eliminates significant regulatory differences between the U.S. and European airworthiness standards.
Airworthiness Directives; Boeing Model 737-600, -700, -700C, and -800 Series Airplanes
Document Number: 06-3442
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 737-600, -700, - 700C, and -800 series airplanes. The existing AD currently requires replacing the point ``D'' splice fitting between windows number 1 and 2 with a new splice fitting; performing an eddy current inspection for cracking of the holes in the structure common to the new splice fitting, including doing any related investigative actions; and performing corrective actions if necessary. This proposed AD would add repetitive inspections for cracking of the skin just below each splice fitting, and related corrective actions if necessary. This proposed AD results from full-scale fuselage fatigue testing on the splice fitting that failed prior to the design objective on Boeing Model 737-800 series airplanes, and a report of a cracked splice fitting on an operational airplane. We are proposing this AD to prevent cracking of the existing fitting, which may result in cracking through the skin and consequent decompression of the flight cabin.
Airworthiness Directives; McDonnell Douglas Model DC-9-10, -20, -30, -40, and -50 Series Airplanes
Document Number: 06-3441
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all McDonnell Douglas Model DC-9-10, -20, -30, -40, and -50 series airplanes. This proposed AD would require replacing the clamp bases for the fuel vent pipe with improved clamp bases. This proposed AD results from reports that the foil wrapping on existing plastic clamp bases has migrated out of position, which compromises the bonding of the fuel vent lines to the airplane structure. We are proposing this AD to ensure that the fuel vent lines are properly bonded to the airplane structure. Improper bonding could prevent electrical energy from a lightning strike from dissipating to the airplane structure, and create an ignition source, which could result in a fuel tank explosion.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
Document Number: 06-3440
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135BJ airplanes. This proposed AD would require 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 proposed 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 proposing this AD to detect and correct such discrepancies on the partitions of the forward baggage compartment door, which, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
Document Number: 06-3439
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This proposed AD would require repetitive inspections for cracks of the first fuel access panel outboard of the nacelle on the left- and right-hand wings, and related investigative/corrective actions if necessary. This proposed AD also would require eventual replacement of each access panel with a new access panel having a new part number. The replacement would terminate the repetitive inspection requirements. This proposed AD results from reports of cracks of the fuel access panels. We are proposing this AD to detect and correct cracked fuel access panels, which could lead to arcing and ignition of fuel vapor during a lightning strike, and result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200F, 747-300, 747-400, 747-400D, 747SP, 747SR, 767-200, 767-300, 777-200, 777-300, and 777-300ER Series Airplanes

This AD requires modification of certain flight deck door electronic equipment. This AD results from a report indicating that this equipment is defective. We are issuing this AD to prevent failure of this equipment, which could jeopardize flight safety.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315 Airplanes; Equipped with Certain Cockpit Door Installations
Document Number: 06-3435
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, - 311, -314, and -315 airplanes. This proposed AD would require modifying the hinge attachment for the cockpit door from a single-point attachment to a two-point attachment. This proposed AD results from a report that, during structural testing of the cockpit door, the lower hinge block rotated and caused the mating hinge pin to disengage, and caused excessive door deflection. We are proposing this AD to prevent failure of a door attachment, which could result in uncontrolled release of the cockpit door under certain fuselage decompression conditions, and possible damage to the airplane structure.
Airworthiness Directives; Boeing Model 747 Airplanes
Document Number: 06-3433
Type: Proposed Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 747 airplanes. This proposed AD would require repetitive inspections for cracking of the web of the station (STA) 2360 aft pressure bulkhead around the fastener heads in the critical fastener rows in the web lap joints, from the Y-chord to the inner ring; and repair if necessary. This proposed AD also would require a modification, which would terminate the repetitive inspections. This proposed AD results from analysis by the manufacturer that the radial lap splices of the STA 2360 aft pressure bulkhead are subject to widespread fatigue damage. We are proposing this AD to detect and correct cracking of the bulkhead web at multiple sites along the radial lap splice, which could join together to form cracks of critical length, and result in rapid decompression and loss of control of the airplane.

Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for McDonnell Douglas DC- 8-72F airplanes modified by Avionics and Systems Integration Group, LLC. 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 Universal Avionics Systems Corporation EFI-600 Electronic Flight Instruments that perform critical functions. 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 that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Airworthiness Directives; Aerospatiale Model ATR42 Airplanes
Document Number: 06-3382
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR42 airplanes. This AD requires one-time inspections to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) of the upper skin and rib feet of the outer wing boxes, and repair if necessary. This AD results from a report of cracking on the upper skin and ribs of the outer wing box on an in- service airplane. We are issuing this AD to detect and correct these discrepancies, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Boeing Model 757 Airplanes Powered by Pratt & Whitney Engines
Document Number: 06-3381
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires repetitive inspections for corrosion and cracking of the midspar fittings in the nacelle struts, and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections. This AD results from reports of corrosion and cracking on midspar fittings on the nacelle struts of several Boeing Model 757 airplanes. We are issuing this AD to detect and correct cracking in the midspar fittings of the nacelle struts, consequent reduced structural integrity of the struts, and possible separation of an engine and strut from the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model DC-8-50, -60, -60F, -70, and -70F Series Airplanes; Model DC-9-10, -20, -30, -40, and -50 Series Airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) Airplanes; and Model MD-88 Airplanes
Document Number: 06-3380
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas airplanes, as listed above. That AD currently requires an initial general visual or dye penetrant inspection, repetitive dye penetrant inspections, and replacement, as necessary, of the rudder pedal bracket. This new AD also requires, for certain airplanes, replacing the rudder pedal bracket assemblies with new, improved parts, which terminates the repetitive inspections. This AD results from a report of numerous cracked rudder pedal brackets found during inspections of certain affected airplanes. We are issuing this AD to prevent failure of the rudder pedal bracket assembly, which could result in the loss of rudder and braking control at either the captain's or first officer's position.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ Airplanes
Document Number: 06-3379
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This AD requires modifying the control cable duct on the left bulkhead structure at frame 12, and, for certain airplanes, the forward toilet bulkhead structure. This AD results from a structural analysis by the manufacturer that revealed that rapid decompression of the flight compartment with the door closed could cause structural deformation of the left bulkhead structure at frame 12, and of the attached cable duct structure. The duct structure protects the cables for the primary flight controls. We are issuing this AD to prevent deformation of the cable duct structure in the event of a rapid decompression, which could result in restriction of the primary flight controls and consequent reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 757 Airplanes
Document Number: 06-3378
Type: Rule
Date: 2006-04-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 757 airplanes. This AD requires repetitive measurements of the freeplay of each of the three power control units (PCUs) that move the rudder; repetitive lubrication of rudder components; and corrective actions if necessary. This AD results from a report of freeplay-induced vibration of the rudder. 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 divergent flutter and loss of control of the airplane.
