First Meeting: RTCA Special Committee 232, Airborne Selective Calling Equipment
The FAA is issuing this notice to advise the public of the first meeting of RTCA Special Committee 232, Airborne Selective Calling Equipment.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This proposed AD was prompted by reports of cracks at the lower forward corner of the main entry door (MED) 1 cutout. This proposed AD would require repetitive inspections of the MED door 1 for cracking, and repair if necessary. This proposed AD also provides optional terminating modification; and would require post- repair or post-modification inspections for cracking, and corrective actions if necessary. We are proposing this AD to detect and correct skin cracking, which can become large and could adversely affect the structural integrity of the airplane.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for Pacific Aerospace Limited Models FU24-954 and FU24A-954 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of control column at the wiring access hole, which could lead to loss of control. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; AgustaWestland S.p.A. Helicopters
We are publishing a new airworthiness directive (AD) for certain AgustaWestland S.p.A. Model AB139 and AW139 helicopters. This AD requires repetitively inspecting the Main Rotor (M/R) Rotating Scissors for play of the Lower Half Scissor Spherical Bearing (bearing) and removing the bearing if there is play beyond allowable limits. This AD also requires removing all affected bearings. This AD is prompted by reports of certain bearings dislodging from certain M/R Rotating Scissors. These actions are intended to detect excessive play of the bearing and prevent failure of the M/R Rotating Scissors and subsequent loss of control of the helicopter.
Airworthiness Directives; Fuji Heavy Industries, Ltd. Airplanes
We are adopting a new airworthiness directive (AD) for Fuji Heavy Industries, Ltd. Models FA-200-160, FA-200-180, and FA-200-180AO airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as deterioration of brake performance due to seal defects caused by deterioration due to age of the O-rings of the brake master cylinder. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France)
We are publishing a new airworthiness directive (AD) for Airbus Helicopters Model EC130B4 and EC130T2 helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires repetitively inspecting the Fenestron to tailboom junction frame (junction frame) for a crack. This AD is prompted by reports of a crack propagating through the junction frame on two EC130B4 helicopters. These actions are intended to detect a crack and to prevent failure of the junction frame, which could result in loss of the Fenestron and subsequent loss of control of the helicopter.
Airworthiness Directives; MD Helicopters, Inc., Helicopters
We are adopting a new airworthiness directive (AD) for MD Helicopters, Inc. (MDHI), Model MD900 helicopters. This AD requires an eddy current inspection of the main rotor upper hub assembly (upper hub) for a crack and replacing the upper hub with an airworthy upper hub before further flight if there is a crack. This AD is prompted by a report of cracks on an upper hub at the blade attach holes. The actions specified by this AD are intended to detect a crack in the upper hub to prevent failure of the upper hub and subsequent loss of control of the helicopter.
Airworthiness Directives; Mooney International Corporation Airplanes
We are adopting a new airworthiness directive (AD) for certain Mooney International Corporation Models M20C, M20E, M20M, M20R, and M20TN airplanes. This AD requires inspection of the outer empennage attach fittings for correct thickness with replacement as necessary. This AD was prompted by discovery of empennage attach fittings (Lugs) that do not meet the approved design dimensional requirements, which could result in possible reduction in fatigue or static strength and/or corrosion. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; the Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 89-12-10, for certain The Boeing Company Model 747 airplanes. AD 89-12-10 required replacement of certain underwing fuel tank access doors with stronger, fire-resistant doors. This new AD requires inspecting certain fuel tank access doors for installation of impact-resistant doors, and stencils and index markers; corrective actions if necessary; revising the maintenance program to incorporate certain new airworthiness limitations; and adding airplanes to the applicability. This AD was prompted by a report of a standard access door installed instead of an impact-resistant access door and stencils missing from some impact- resistant access doors and adjacent wing skin. We are issuing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900 and -900ER series airplanes. This AD was prompted by reports of incorrectly installed bolts common to the rear spar termination fitting on the horizontal stabilizer. This AD requires inspecting for a serial number that starts with the letters ``SAIC'' on the left- and right-side horizontal stabilizer identification plate; inspecting for correct bolt protrusion and chamfer of the bolts of the rear spar termination fitting of the horizontal stabilizer, if necessary; inspecting to determine if certain bolts are installed, if necessary; and doing related investigative and corrective actions if necessary. We are issuing this AD to prevent loss of structural integrity of the horizontal stabilizer attachment and loss of control of the airplane.
Airworthiness Directives; Saab AB, Saab Aerosystems Airplanes
We are adopting a new airworthiness directive (AD) for certain Saab AB, Saab Aerosystems Model SAAB 2000 airplanes. This AD was prompted by a report of rudder pedal restriction which was the result of water leakage at the inlet tubing of an in-line heater in the lower part of the forward fuselage. This AD requires deactivating the potable water system, or alternatively filling and activating the potable water system. We are issuing this AD to prevent rudder pedal restriction due to the pitch control mechanism becoming frozen as the result of water spray, which could prevent disconnection and normal pitch control, and consequently result in reduced controllability of the airplane.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of silicon particles inside the oxygen generator manifolds, which had chafed from the mask hoses during installation onto the generator outlets. This AD requires identifying the part number and serial number of each passenger oxygen container, replacing the oxygen generator manifold of any affected oxygen container with a serviceable manifold, and performing an operational check of the manual mask release, and corrective actions if necessary. We are issuing this AD to detect and correct non-serviceable oxygen generator manifolds, which could reduce or block the oxygen supply and result in injury to passengers when oxygen supply is needed.
