Airworthiness Directives; Airbus Model A300 B2 Series Airplanes; Model A300 B4 Series Airplanes; Model A300 B4-600 Series Airplanes; Model A300 B4-600R Series Airplanes; Model F4 600R Series Airplanes; Model A300 C4-605R Variant F Airplanes; and Model A310-200 Series Airplanes; and Model A310-300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus transport category airplanes. This proposed AD would require replacing the existing cabin altitude indicator in the cabin pressure control panel with a new, improved cabin altitude indicator. This proposed AD is prompted by a report of injuries occurring on in- service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure causing the doors to rapidly open. We are proposing this AD to prevent injury to crewmembers, and subsequent damage to the airplane caused by rapid opening of the door.
Airworthiness Directives; Hamburger Flugzeugbau G.m.b.H. Model HFB 320 HANSA Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Hamburger Flugzeugbau G.m.b.H. Model HFB 320 HANSA airplanes. This proposed AD would require revising the Limitations Section of the Airplane Flight Manual to prohibit operation of the airplane past its designed life limit for the primary structure, which is 15,000 flight hours or 15,000 fight cycles, whichever occurs first; and to require contacting the FAA for approval of analysis that the airplane is safe to continue operation beyond the designed life limit. This proposed AD is prompted by a report that all airplanes in operation might have met or exceeded the designed life limit for the primary structure. We are proposing this AD to prevent continued operation of an airplane beyond its designed life limit for the primary structure, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Sabreliner Model NA-265, NA-265-20, NA-265-30, NA-265-40, NA-265-50, NA-265-60, NA-265-65, NA-265-70, and NA-265-80 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Sabreliner Model NA-265-40, NA- 265-50, NA-265-60, NA-265-70, and NA-265-80 series airplanes. The existing AD currently requires repetitive inspections for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib, and corrective actions if necessary. This proposed AD would expand the applicability of the existing AD and require new repetitive inspections for fuel leaks of the front and rear spars of the wing, and for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib. This proposed AD would also require related investigative and corrective actions, if necessary. This proposed AD results from reports of cracking in the upper and lower flanges of the front and rear spars of the wing near the wing center section, and in the lugs on the rear spar. We are proposing this AD to detect and correct cracking or other discrepancies in these areas, which could result in structural failure of the wing.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This proposed AD would require an inspection of the laminated shims for cracks, damage, or extrusion between the forward attachment fittings of the horizontal stabilizer and the top rib of the vertical stabilizer; a torque check of the attachment bolts in the attachment fittings of the front, middle, and rear spars; and corrective actions if necessary. This proposed AD results from a report indicating that delaminated shims extruded from the interface between the forward attaching fittings of horizontal stabilizer and the top rib of the vertical stabilizer, and that inadequate torque values of some bolts were found. We are proposing this AD to prevent reduced structural integrity of the horizontal stabilizer, and consequent loss of controllability of the airplane.
Airworthiness Directives; Burkhardt Grob Luft-Und Raumfahrt GmbH & CO KG Model G103 TWIN ASTIR Sailplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Burkhardt Grob Luft-Und Raumfahrt GmbH & CO KG (Grob) Model G103 TWIN ASTIR sailplanes. This proposed AD would require you to replace the elevator lever, part number (P/N) 103-3521, with a part of improved design, P/N 103-3523. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to prevent cracks in the elevator lever, which could cause the elevator lever to fail. This failure could result in loss of control of the sailplane.
Service Difficulty Reports
The Federal Aviation Administration is proposing to withdraw a final rule published on September 15, 2000 that would have amended the reporting requirements for certificate holders concerning failures, malfunctions, and defects of aircraft, aircraft engines, systems, and components. The effective date of this final rule has been delayed several times and is now January 31, 2006. We are proposing to withdraw this rule to allow the FAA time to re-examine the service difficulty report (SDR) program based on comments received and other developments since the final rule was published. We are also proposing several amendments that improve the existing SDR program because they did not receive significant comment when proposed in the final rule.
Airworthiness Directives; Aerospatiale Model ATR42-500 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR42-500 airplanes. This AD requires inspecting for correct installation of the fastener that attaches the ground braids on the elevator, modifying the forward bonded assembly of the elevator control rod, and corrective action if necessary. This AD results from a functional test of the elevator trim tab control rod of the leading edge, which showed that, in a full-up elevator condition with the tab fully down, interference could occur between the tab control rod and the forward edge of the lower skin of the elevator. We are issuing this AD to prevent discrepancies between the elevator trim tab control rod and the forward edge of the lower skin of the elevator, which could result in reduced control of the elevator and consequent reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A340-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A340-200 and -300 series airplanes. This AD requires revising the airplane flight manual to incorporate new procedures for the flightcrew to follow to correct miscalculation of the takeoff and accelerating or stopping distance of the airplane during a ferry flight under certain conditions. This AD results from a report that a software error could result in a miscalculation (underestimation) of the runway length necessary for takeoff in the case of a ferry flight with one engine not operating. We are issuing this AD to prevent this miscalculation, which, if combined with high takeoff weight, too-short runway length, and high altitude and temperature of the airport, could result in inability of the flightcrew to abort the takeoff in a safe manner, reduced controllability of the airplane, and runway overrun.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 airplanes. This AD requires inspecting the hydraulic pressure tubes at the outlet of the engine-driven hydraulic pumps to determine the part and serial numbers; and replacing hydraulic pressure tubes having certain serial numbers with new hydraulic pressure tubes. This AD results from failure of a hydraulic system due to leakage of hydraulic fluid from a crack in the pipe coming from the pressure side of the engine-driven pump. We are issuing this AD to prevent cracking of the hydraulic pressure pipes, which could result in failure of hydraulic system 1 or 2 or both, and consequent reduced controllability of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-110P1 and EMB-110P2 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model EMB-110P1 and EMB-110P2 airplanes. This AD requires repetitive inspections for corrosion or cracking of the rotating cylinder assembly in the nose landing gear (NLG), and related investigative/corrective actions if necessary. This AD also requires the eventual replacement of the rotating cylinder assembly with a new part, which terminates the need for the repetitive inspections. This AD results from reports of corrosion on the NLG rotating cylinder assembly. We are issuing this AD to prevent cracks from emanating from corrosion pits in the NLG rotating cylinder assembly, which could result in failure of the NLG.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires modification of the splice plate assemblies installed under the floor panels at the forward and aft edges of the cabin aisle. This AD results from reports of cracking of the aluminum splice plates under the floor panels in the cabin aisle. We are issuing this AD to prevent loss of the capability of the cabin floor and seat track structure to support the airplane interior inertia loads under emergency landing conditions. Loss of this support could lead to galley or seat separation from attached restraints, which could result in blocking of the emergency exits and consequent injury to passengers and crew.
Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. That AD currently requires either determining exposure to runway deicing fluids containing potassium formate, or performing repetitive inspections of certain electrical connectors in the wheel well of the main landing gear (MLG) for corrosion, and follow-on actions. This new AD adds a new inspection requirement and related corrective actions. This AD is prompted by additional reports indicating that significant corrosion of the electrical connectors in the wheel well of the MLG has also been found on airplanes that land on runways treated with deicing fluids containing potassium acetate. We are issuing this AD to prevent corrosion and subsequent moisture ingress into the electrical connectors, which could result in an electrical short and consequent incorrect functioning of critical airplane systems essential to safe flight and landing of the airplane, including fire warning systems.
