2001-16-10: This amendment adopts a new airworthiness directive (AD), applicable to all Aerospatiale Model ATR42-200, -300, -320, and -500 series airplanes; and all Model ATR72 series airplanes. The AD requires revising the Airplane Flight Manual to modify procedures for calculating takeoff performance when Type II or IV de-icing or anti-icing fluids have been used. This amendment is prompted by reports that use of these de-icing or anti-icing fluids may result in an increase in the pitch forces necessary to rotate the airplane during takeoff. This condition could result in a delayed takeoff or even late aborted takeoff. The actions specified by this AD are intended to ensure that the flight crew is advised of the potential effects of Type II or IV de-icing or anti-icing fluids on the airplane's performance during takeoff, and to ensure that the flight crew is advised of the revised performance calculations for takeoff to address these effects.
2001-17-10: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that currently requires a one-time inspection to detect riding, chafing, or damage of the wire bundles adjacent to the disconnect panel bracket of the observer's station. That AD also requires repair or replacement of damaged wires with new or serviceable wires; installation of anti-chafing sleeving on the wire bundles, if necessary; and installation of a grommet along the entire upper aft edge of the disconnect panel bracket. This amendment requires an identical one-time inspection, follow-on actions, and similar corrective actions, if necessary; but the installation of anti-chafing sleeving will be required for all airplanes. The actions specified by this AD are intended to detect riding or chafing of the wire bundles adjacent to the disconnect panel bracket assembly, which could result in a fire in the wire bundles and smoke in the cockpit. This action is intended to address the identified unsafe condition.
2001-17-11: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires an inspection to detect arcing damage of the electrical cables leading to the hydraulic pump terminal strips and the surrounding structure in the wheel well area of the right main landing gear (MLG); and corrective actions, if necessary. This AD also requires replacement of a certain terminal strip with a new terminal strip, and removal of the applicable nameplate in the wheel well of the right MLG. For certain airplanes, this AD also requires, as an alternative, an inspection of the terminal strip to determine if the correct washer is installed, and replacement of the incorrect washer with a new washer. This action is necessary to prevent arcing damage to the terminal strips and damage to the adjacent structure of the wheel well area of the right MLG, which could result in a fire in the wheel well of the right MLG. This action is intended to address the identified unsafe condition.
2001-17-06: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires replacement of the cargo roller circuit breakers with new circuit breakers, and reidentification of the aft circuit breaker panel; as applicable. This action is necessary to prevent possible overheating of cargo control unit components, which could result in smoke and/or fire in the cargo compartment. This action is intended to address the identified unsafe condition.
97-25-17: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 and A321 series airplanes, that requires a revision to the Airplane Flight Manual (AFM) to include procedures for the flightcrew to follow in the event of radio altimeter height malfunction. This amendment also requires replacement of certain radio altimeter antennas with improved antennas, at which time the AFM revision will no longer be required. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent output of erroneous radio altimeter height information to the flightcrew and autopilot, which could result in reduced ability of the flightcrew to cope with adverse operating conditions.
2016-25-19: We are superseding airworthiness directive (AD) 2010-21-07 for Eurocopter France (now Airbus Helicopters) Model AS350B3 and EC130B4 helicopters. AD 2010-21-07 required inspecting the pilot's and co- pilot's throttle twist for proper operation of the contactors. This new AD retains the requirements of AD 2010-21-07, includes additional inspection procedures, and revises the inspection interval. These actions are intended to address the unsafe condition on these products.
2001-17-04: This amendment adopts a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135ER and -135LR series airplanes, and Model EMB-145, -145ER, -145MR, and -145LR series airplanes. This action requires a one-time visual inspection to determine if the two bonding jumpers that connect the horizontal stabilizer to the vertical stabilizer are properly installed, and replacement of the jumper with a new jumper, if necessary. This action also requires a one-time visual inspection to determine if the supports that connect the bonding jumpers to the horizontal stabilizer are deformed, and corrective actions, if necessary. This action is necessary to prevent severed bonding jumpers in the event of a lightning strike, which could result in reduced elevator control capability, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
