2008-09-03: We are adopting a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) model helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, states in the MCAI: It has been reported, on an A109A helicopter, a case of failure of the grooved clamp fixing the engine exhaust duct, with the consequent loss of the duct. The duct has hit the main and tail rotor producing the loss of the tail rotor and the emergency landing of the helicopter. The fracture of the grooved clamp was due to excessive loads and corrosion around the attaching rivets. This AD requires actions that are intended to address this unsafe condition.
2001-16-09: This amendment supersedes an existing airworthiness directive (AD), which is applicable to all Model A320 series airplanes, that currently requires repetitive measurements of the deflection of the elevator trailing edge; inspections of the elevator servo controls and their attachments; and replacement of worn or damaged parts, if necessary. This amendment requires periodic inspection of the elevators for excessive freeplay, repair of worn parts if excessive freeplay is detected, and modification of the elevator neutral setting. It also revises the applicability to include additional airplane models. This amendment is prompted by additional reports of severe vibration in the aft cabin of Model A320 series airplanes and studies that indicate that the primary cause is excessive freeplay in the elevator attachments. The actions specified by this AD are intended to prevent excessive vibration of the elevators, which could result in reduced structural integrity and reduced controllability of the airplane.
2020-16-01: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of low halon concentration in the forward and aft cargo compartments due to air leakage through cargo door seals. This AD requires repetitive cleaning and greasing of affected cargo door seals, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
95-09-12: This amendment supersedes Airworthiness Directive (AD) 88-11-05, which currently requires repetitively inspecting the wing spar of Alexander Schleicher Models ASW-15 and ASW-15B gliders for wood rot, and replacing any wing spar where wood rot is found. Alexander Schleicher Models ASW-12 and ASW-17 gliders are of a similar type design to Models ASW-15 and ASW-15B gliders, and the Federal Aviation Administration (FAA), in working with the Civil Aviation Authority of Germany, has decided that the actions referenced in AD 88-11-05 should also apply to Models ASW-12 and ASW-17 gliders. The actions specified by this AD are intended to prevent failure of the wing spar caused by wood rot, which, if not detected and corrected, could result in loss of control of the airplane.
2008-08-11: This amendment adopts a new airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 series helicopters that requires modifying the pilot and co-pilot dual-control directional pedal assemblies, or the pilot single-control directional pedal assembly (directional control pedal assembly). This amendment is prompted by an accident which has been attributed to loss of directional control due to failure of the welds in the directional control pedal assembly. The actions specified by this AD are intended to prevent fatigue cracking in the welds that connect the directional control pedal to the pedal shaft, resulting in loss of directional control and subsequent loss of control of the helicopter.
95-09-08: This amendment adopts a new airworthiness directive (AD) that is applicable to McCauley Model 2A37C223/90RB propellers. This action requires installation of internal steel components, replacement of a balance ring, replacement of cylinder mounting screws, and modification to an oil-filled configuration with red dye. Replacement of the identified components redistributes propeller weight while the red dye oil-filling provides an "on-condition" (in-service) means of early crack detection of the propeller assembly and also improves lubrication and corrosion protection. Any screw failures or cracks found during the accomplishment of this AD must be reported to the FAA. This amendment is prompted by a report of a propeller found with at least one cylinder screw that had failed due to fatigue. The actions specified in this AD are intended to prevent cylinder screw failure that could result in loss of propeller control and subsequent loss of aircraft control.
2001-16-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737 series airplanes, that requires initial and repetitive inspections of certain areas of the wing spars to detect cracking or corrosion; and follow-on corrective actions and repair, if necessary. This amendment is prompted by reports of cracks and corrosion in the upper chord of the front and rear spars of the wing and reports of cracks propagating from previously repaired areas. The actions specified by this AD are intended to detect and correct such cracking or corrosion of the upper and lower chords of the wing spars, which could result in reduced structural integrity of the wing.
74-08-09 R1: This amendment revises an existing airworthiness directive (AD) that is applicable to all transport category airplanes. The existing AD currently requires installation of placards prohibiting smoking in the lavatory and disposal of cigarettes in the lavatory waste receptacles; establishment of a procedure to announce to airplane occupants that smoking is prohibited in the lavatories; installation of ashtrays at certain locations; and repetitive inspections to ensure that lavatory waste receptacle doors operate correctly. That action was prompted by fires occurring in lavatories, which were caused by, among other things, the improper disposal of smoking materials in lavatory waste receptacles. The actions specified by the AD are intended to prevent such fires. This amendment provides for an alternative action regarding the current requirement to install specific placards at certain locations.
2008-09-10: The FAA is adopting a new airworthiness directive (AD) to supersede AD 2003-06-01, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-300, AT-301, AT-302, and AT-400A airplanes that have aluminum spar caps; certain Air Tractor Models AT-400 airplanes that have aluminum spar caps; and all Models AT-300 and AT-301 airplanes that have aluminum spar caps and are or have been converted to turbine power. AD 2003-06-01 requires replacing the wing spar lower caps at a specified safe life limit; allows extending the safe life limit on certain airplanes if a wing lower spar cap splice rework is done; allows a limited time of continued operation beyond the safe life limit provided parts are ordered, the replacement is scheduled, and repetitive inspections reveal no cracks; and requires a report of any cracks found during any inspection to the FAA. This AD results from a recent report of cracks found on a Model AT-301 airplane at hours below the modification time specified inAD 2003-06-01. Consequently, this AD retains the wing spar lower cap replacement and reporting requirements from AD 2003-06-01 and adds a repetitive eddy-current inspection. We are issuing this AD to detect and correct cracks in the wing centerline splice joint. If not detected and corrected, these cracks could result in the wing separating from the airplane during flight. \n\nDATES: This AD becomes effective on May 8, 2008. \n\tOn May 8, 2008, the Director of the Federal Register approved the incorporation by reference of Snow Engineering Co. Service Letter 55, revised October 4, 2004, listed in this AD. \n\tAs of April 4, 2003, (68 FR 13221, March 19, 2003), the Director of the Federal Register approved the incorporation by reference of Snow Engineering Co. Service Letter 55, revised October 23, 2002, and Snow Engineering Co.
