2023-19-06: The FAA is superseding Airworthiness Directive (AD) 64-09-03, which applied to all de Havilland (type certificate now held by Viking Air Limited (Viking)) Model DHC-2 ''Beaver'' airplanes. AD 64-09-03 required inspecting the aileron mass balance weight arms for cracks and corrosion and replacing any damaged part. Since the FAA issued AD 64- 09-03, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This AD requires incorporating into the existing maintenance records for your airplane the actions and associated thresholds and intervals, including life limits, specified in a supplemental inspection and corrosion control manual for Model DHC-2 airplanes. This AD also requires completing all of the initial tasks identified in this manual and reporting certain corrosion findings to Viking. The actions in this supplemental inspection and corrosion control manual include the inspection of the aileron balance weight arms required by AD 64-09-03. The FAA is issuing this AD to address the unsafe condition on these products.
94-22-01: This amendment supersedes an existing airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-10-10, -10F, -30, and -30F series airplanes, that currently requires inspections to detect ice or snow accumulation on top of the fuselage and in the inlet of the number 2 engine, and removal of ice and snow accumulation. This amendment adds certain airplanes to the applicability of the rule and limits the inspection requirement to only a certain group of airplanes. This amendment is prompted by the development of improved fan blades on certain engines and the identification of additional airplanes that are subject to the unsafe condition. The actions specified by this AD are intended to minimize damage to the number 2 engine due to ingestion of ice and snow.
2002-15-03: This amendment supersedes an emergency airworthiness directive (AD) 2002-05-51 that was sent previously to all known U.S. owners and operators of Hamilton Sundstrand Corporation (formerly Hamilton Standard Division) model 568F-1 propellers. That AD requires replacement of propeller blades, part numbers (P/N's) R815505-2 and R815505-3, that have a serial number (SN) of FR1698 or lower, with serviceable propeller blades, a prohibition against installing any propeller blades, P/N's R815505-2 and R815505-3, that have a SN of FR428 or lower, that were previously installed on an ATR-42-400 or an ATR-72 airplane, on any other airplane, and initial and repetitive ultrasonic shear wave inspection of the blade tulip on installed blades P/N's R815505-2 and R815505-3, that have a SN of FR1698 or lower. This amendment requires those same actions, and also requires replacing certain SN blades before further flight. This amendment also requires initial and repetitive ultrasonic shear wave inspections of the blade tulip on installed blades, P/N's R815505-2 and R815505-3, that have a SN of FR1698 or lower until they are replaced. This amendment is prompted by a report of a blade failure that resulted in damage to the airplane. The actions specified in this AD are intended to prevent blade failure due to corrosion-induced fatigue, which could result in blade separation and possible loss of airplane control.
2023-19-05: The FAA is superseding Airworthiness Directive (AD) 2017-19-22 for all British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. AD 2017-19-22 required incorporating BAE Systems' Corrosion Prevention and Control program into the Airworthiness Limitations Section (ALS) of the existing instructions for continued airworthiness (ICA) for your airplane, which added new and more restrictive inspections for corrosion that include inspecting the door hinges/supporting structure and attachment bolts for the main spar joint and engine support, and the rudder hinge location on the vertical stabilizer, and applicable corrective actions. Since the FAA issued AD 2017-19-22, the Civil Aviation Authority (CAA) of the United Kingdom (UK) superseded the mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) to correct an unsafe condition on these products. This AD requires revising the ALS of the existing ICA for your airplane. The FAA is issuing this AD to address the unsafe condition on these products.
94-19-51 R1: This document revises and publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T94-19-51 that was sent previously to all known U.S. owners and operators of McDonnell Douglas Model MD-11 and MD-11F series airplanes by individual telegrams. This AD supersedes an existing airworthiness directive that currently requires a revision to the Airplane Flight Manual (AFM) to ensure that the flight crews verify the accuracy of data provided by the Flight Management Computer (FMC) under certain conditions. This amendment requires a revision to the AFM to ensure that the flight crews verify the accuracy of data provided by the FMC under all conditions. This amendment is prompted by a report that the "check/confirm V speed" message may be inhibited when the flaps are extended to within three degrees of the takeoff flap setting that was entered into the FMC. The actions specified by this AD are intended to prevent FMC miscalculations that may result in excessively high takeoff decision (V1) speeds, which may adversely affect accelerate-stop distances and may lead to the failure of the airplane to stop prior to departing the end of the runway during a high speed rejected takeoff. This amendment also revises the previously issued telegraphic AD by correcting a typographical error in the listing of the part numbers for the FMC's.
2023-19-09: The FAA is superseding Airworthiness Directive (AD) 2020-24- 04, which applied to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2020-24-04 required revising the existing airplane flight manual (AFM) to incorporate procedures for an approach with a localizer-based navigation aid, monitoring localizer raw data, calling out any significant deviations, and performing an immediate go around under certain conditions. This AD was prompted by the development of a modification to address the previously identified unsafe condition, and the identification of a separate unsafe condition where misleading vertical flight director (FD) guidance can be presented to the flightcrew under certain conditions. This AD continues to require the actions specified in AD 2020-24-04 and requires installing applicable software updates to the flight control module (FCM). Using updated software terminates the retained AFM requirement in this AD. The FAA is issuing this AD to address the unsafe condition on these products.
2002-15-02: This amendment adopts a new airworthiness directive (AD), that is applicable to Hamilton Sundstrand Power Systems (formerly Sundstrand Power Systems, Turbomach, and Solar) T-62T series auxiliary power units (APU's) with compressor wheel part number (P/N) 100636-1 installed. This amendment requires the replacement of compressor wheels P/N 100636-1. This amendment is prompted by a manufacturer's stress analysis that indicates stress levels high enough to initiate and drive crack growth in these compressor wheels. The actions specified by this AD are intended to mandate the replacement of the affected compressor wheels, which if not replaced, could result in uncontained compressor wheel failure and damage to the airplane.
2002-15-01: This amendment adopts a new airworthiness directive (AD) that applies to all Diamond Aircraft Industries GmbH (Diamond) Models H-36 "Dimona", HK 36 R "Super Dimona", HK 36 TC, HK 36 TS, HK 36 TTC, HK 36 TTC-ECO, HK 36 TTC-ECO (Restricted Category), and HK 36 TTS sailplanes. This AD requires you to inspect the long aileron push rods in both wings for damage and modify the push rods. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Austria. The actions specified by this AD are intended to detect and correct damage in the long aileron push control rods, which could result in failure of the aileron push rods and decreased control. Such failure could lead to aeroelastic flutter.
2011-04-03: We are adopting a new airworthiness directive (AD) for the products listed above. This 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: During flight-testing of a wing anti-ice piccolo tube containing a deliberate small breach, it was determined that the wing leading edge thermal switches Part Number (P/N) 601R59320-1 were not detecting the consequent bleed leak at the design threshold. As a result, Airworthiness Limitation (AWL) tasks, consisting of a functional check of the wing leading edge thermal switches (P/N 601R59320-1) and an inspection of the wing anti-ice duct piccolo tubes on aeroplanes with these switches installed, have been introduced. These tasks will limit exposure to dormant failure of the wing leading edge thermal switches in the event of piccolo tube failure, whichcould potentially compromise the structural integrity of the wing leading edge and the effectiveness of the wing anti-ice system. * * * * * The unsafe condition is loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2002-14-26: This amendment adopts a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arriel models 1A, 1A1, 1B, 1D, and 1D1 turboshaft engines. This action requires installation of containment shield rings around the free turbine blade area, and installation of a double support around the gearbox free turbine bearing housing. This amendment is prompted by two reports of the cantilevered axis of the free turbine moving from its design position and inducing blade trajectories outside the current design free turbine containment area. This condition can lead to uncontainment of the free turbine during an overspeed event. The actions specified in this AD are intended to prevent uncontainment of the free turbine during an overspeed event, resulting in damage to the helicopter.
