2001-14-08: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10 series airplanes, Model MD-10 series airplanes, and Model MD-11 series airplanes, that requires repetitive inspections of the number 1 and 2 electric motors of the auxiliary hydraulic pump for electrical resistance, continuity, mechanical rotation, and associated wiring resistance/voltage; and corrective actions, if necessary. This amendment is necessary to prevent various failures of electric motors of the auxiliary hydraulic pump and associated wiring, which could result in fire at the auxiliary hydraulic pump and consequent damage to the adjacent electrical equipment and/or structure. This action is intended to address the identified unsafe condition.
2020-09-10: The FAA is superseding Airworthiness Directive (AD) 2018-25- 04, which applied to certain C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2018-25-04 required repetitive inspections for any dislodged blow-out panel in the forward and aft cargo compartments, reporting of the inspection findings, and reinstallation if necessary. This new AD continues to require repetitive inspections, with a revised inspection interval, for affected panels that have not been replaced. This new AD also requires the replacement of affected blow-out panels with redesigned panels, which terminates the inspection requirement. This new AD also revises the applicability by removing certain airplanes. This AD was prompted by reports of dislodged cargo compartment blow-out panels. The FAA is issuing this AD to address the unsafe condition on these products.
2008-05-06: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -300, -400, and -500 series airplanes. This AD requires repetitive inspections for fatigue cracking in the longitudinal floor beam web, upper chord, and lower chord located at certain body stations, and repair if necessary. This AD results from several reports of cracks in the center wing box longitudinal floor beams, upper chord, and lower chord. We are issuing this AD to detect and correct fatigue cracking of the upper and lower chords and web of the longitudinal floor beams, which could result in rapid loss of cabin pressure.
2012-21-20: We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 freighter series airplanes, Model A330-200 and - 300 series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of the ram air turbine (RAT) not deploying when tested. This AD requires identification of the supplier, part number, and serial number of the installed RAT actuator, and re-identification of the actuator and RAT, or replacement of the RAT actuator with a serviceable unit and re-identification of the RAT, if necessary. We are issuing this AD to prevent non-deployment of the RAT, which if occurred following a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
2001-23-11: This amendment supersedes an airworthiness directive (AD) for Eurocopter France Model EC 155B helicopters that currently requires, before each flight, visually checking each sliding door to ensure that each door roller is inside its rail. This amendment requires modifying the cabin sliding door rails and replacing the roller fitting. This amendment is prompted by the development of a modification that mechanically restrains the roller within its rail. The actions specified by this AD are intended to prevent in-flight loss of a cabin sliding door, impact with the main rotor or fenestron, and subsequent loss of control of the helicopter.
2018-17-22: We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-115 and -132 airplanes, and Model A320-214, -216, -232, and -233 airplanes. This AD was prompted by a report indicating that certain modified airplanes do not have electrical ground wires on the fuel level sensing control unit (FLSCU), which adversely affects the fuel gravity feeding operation. This AD requires modification of the FLSCU wiring. We are issuing this AD to address the unsafe condition on these products.
2008-05-11: We are adopting a new airworthiness directive (AD) to supersede AD 76-23-03 R1, which applies to certain Alexandria Aircraft, LLC Models 17-30, 17-31, 17-30A, and 17-31A airplanes. AD 76-23-03 R1 currently requires you to inspect the muffler and tailpipe assemblies for cracks and inspect the exhaust assembly for freedom of movement at the ball joints. Since we issued AD 76-23-03-R1, we have received additional reports of in-flight exhaust system failures. Consequently, this AD reduces the exhaust system inspection interval; requires a more detailed inspection of the muffler; and requires replacement, reconditioning, or repair of the exhaust system if cracks or defects are found. This AD also requires P-lead rerouting. We are issuing this AD to detect and correct cracks in the exhaust system, which could result in heat damage to magneto electrical wiring and smoke in the cockpit. This failure could lead to loss of engine power and/or a fire in the engine compartment.
94-24-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Short Brothers Model SD3-60 series airplanes, that requires installation of a certain time delay relay and associated wiring into a circuit of the rudder gust lock. This amendment is prompted by reports of inadvertent engagements of the rudder gust lock on in-service Model SD3-60 series airplanes. The actions specified by this AD are intended to prevent premature locking of the rudder gust lock, which could result in reduced controllability of the airplane in flight and during landing roll.
2004-26-12: The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 series airplanes. This AD requires revising the airplane flight manual (AFM) to include certain operational instructions and prohibit dispatch of any flight with the integrated electronic standby system (IESS) inoperative, even though it is allowed by the current version of the Master Minimum Equipment List; and performing a test to determine proper operation of the network interface card (NIC) communications and repairing if necessary. This AD also requires installing a certain software version of the PRIMUS EPIC system, after which the AFM revision must be removed from the AFM. This AD is prompted by reports of temporary loss of all cockpit display units (DU). We are issuing this AD to prevent temporary or possible sustained loss of all modular avionics units (MAU), which triggers a cascade of failures in systems dependent on MAUs functionalities. Such failures could reduce the flightcrew'ssituational awareness and increase workload and consequently reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane.
2001-23-06: This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA--Groupe Aerospatiale (Socata) Model TBM 700 airplanes. This AD requires you to inspect for defective Amendment A fuel tank air vent valves and replace with parts of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent in-flight damage to the wing skins caused by abnormal venting conditions of the wing fuel tank, which could result in severe handling problems or reduced structural capability. Continued operation with such structural deformation or handling problems could result in loss of control of the airplane.
