2021-11-13: The FAA is adopting a new airworthiness directive (AD) for Bell Textron Canada Limited (Bell) Model 429 helicopters. This AD requires inspecting certain serial-numbered Emergency Flotation System (EFS) inflation hoses and depending on the results of those inspections, marking certain parts or removing certain parts from service. This AD was prompted by a report that a float compartment on an EFS did not inflate. The FAA is issuing this AD to address the unsafe condition on these products.
2006-22-08: The FAA adopts a new airworthiness directive (AD) for all Air Tractor, Inc. Models AT-602, AT-802, and AT-802A airplanes. This AD requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. This AD results from reports of cracked engine mounts. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.
2021-12-15: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes. This AD was prompted by a report of an in-flight turnback due to loss of green and blue hydraulic systems in cruise. This AD requires inspecting for discrepancies of the hydraulic pressure switch harnesses of affected engines, and applicable corrective actions, 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.
2018-20-06: We are superseding Airworthiness Directive (AD) 2016-25-03, which applied to certain Airbus Model A300 F4-600R series airplanes. AD 2016-25-03 required repetitive high frequency eddy current (HFEC) inspections of the aft lower deck cargo door (LDCD) frame forks; a one- time check of the LDCD clearances; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. This AD requires repetitive HFEC inspections of the aft LDCD frame forks; a one-time check of the LDCD clearances; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. This AD was prompted by a report of two adjacent frame forks that were found cracked on the aft LDCD of two airplanes during scheduled maintenance, and the introduction of frame fork reinforcement or repair procedures that, when done, allow an extension of repetitive inspection intervals. We are issuing this AD to address the unsafe condition on these products.
2006-22-07: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 and A310 airplanes and A300-600 series airplanes. This AD requires inspecting for discrepancies of all electrical bundles located in the leading and trailing edges of the wings, and performing corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
2021-11-01: The FAA is superseding Airworthiness Directive (AD) 2013-20-13 for certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) (Bell) Model 206B and 206L helicopters. AD 2013-20-13 required installing a placard beneath the engine power dual tachometer and revising the Operating Limitations section of the existing Rotorcraft Flight Manual (RFM) for your helicopter. This AD was prompted by the engine manufacturer expanding the RPM (N2) steady-state operation avoidance range limits. This AD retains certain requirements of AD 2013-20-13, and requires revising certain sections of the existing RFM for your helicopter and installing or replacing a placard. The FAA is issuing this AD to address the unsafe condition on these products.
