2020-16-05: The FAA is adopting a new airworthiness directive (AD) for all Blanik Aircraft CZ s.r.o. Model L 23 Super-Blanik gliders. This AD requires a one-time inspection of the rudder control cable attachment screws and hinge bolts, replacement of the cable attachment screws and hinge bolts if a crack is found, and reporting the inspection results to the manufacturer. This AD was prompted by reports of cracked rudder cable attachment screws. The FAA is issuing this AD to address the unsafe condition on these products.
2008-09-18: The FAA adopts a new airworthiness directive (AD) for certain Taylorcraft, Inc. Models A, B, and F series airplanes. This AD requires you to inspect the wing strut attach fittings for corrosion or cracks and requires repair or replacement if corrosion or cracks are found. This AD results from data collected from an accident involving a Taylorcraft Model BF12-65 airplane. The wing separated from the airplane after the wing strut attach fitting failed due to corrosion. We are issuing this AD to detect and correct corrosion or cracks in the wing strut attach fittings, which could result in failure of the wing strut attach fittings and lead to wing separation and loss of control.
2001-17-03: This amendment adopts a new airworthiness directive (AD) that is applicable to all EMBRAER Model EMB-135 and -145 series airplanes. This action requires repetitive inspections of the engine thrust reverser stow/transit switches, and corrective action, if necessary. This action is necessary to prevent erroneous signals in the Engine Indicating and Crew Alerting System (EICAS) caused by internal corrosion of the thrust reverser stow/transit switches, which could result in uncommanded loss of engine power in flight, or unnecessary aborted takeoffs on the ground. This action is intended to address the identified unsafe condition.
95-10-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-300, -400, and -500 series airplanes, that requires replacement of the horizontal stabilizer trim electric actuator. This amendment is prompted by reports of a binding condition in the clutch disk in the horizontal stabilizer trim electric actuator. The actions specified by this AD are intended to prevent reduced controllability of the airplane due to binding of a clutch disk in the horizontal stabilizer trim electric actuator.
2008-09-17: We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, and MD-10-10F airplanes. This AD requires repetitive inspections for the presence of stray nickel or chrome plating deposits on the air filler valve bore of certain main landing gear (MLG) shock strut cylinders, and if necessary, related investigative and corrective actions. Doing the corrective action terminates the repetitive inspections. This AD results from a report of a left MLG collapse during landing rollout. We are issuing this AD to detect and correct stray nickel and chrome plating deposits, corrosion, and cracking of the air filler valve bore on the MLG cylinder, which could result in landing gear failure, significant damage to the airplane, and injury to personnel.
2001-16-11: This amendment adopts a new airworthiness directive (AD); applicable to certain Boeing Model 737-100, -200, and -200C series airplanes; that requires a one-time inspection of the carriage spindles on the outboard midflap for circumferential score marks; and rework of the carriage spindles or replacement with new or serviceable spindles, if necessary. This action is necessary to prevent severe flap asymmetry due to fractures of both carriage spindles at an outboard midflap, which could result in loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
95-09-07: This amendment adopts a new airworthiness directive (AD) that is applicable to Robinson Helicopter Company Model R44 helicopters. This action requires removal of the push-pull tube sleeve guide assembly (sleeve guide) and replacement with a push-pull tube roller guide assembly (roller guide); and, inspections of the push-pull tube sleeves for signs of wear and replacement as necessary. This amendment is prompted by a report of an operator experiencing binding in the cyclic control system caused by torn heat-shrink material (material) on the cyclic push-pull tubes binding in the sleeve guide. The actions specified in this AD are intended to prevent binding in the cyclic control system and subsequent loss of control of the helicopter.
2008-09-08: We are superseding an existing airworthiness directive (AD) for the products listed above. 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: On the pre-flight check of a SZD-50-3 glider, the Right Hand (RH) wing airbrake was found impossible to retract. Investigation revealed that the occurrence was caused by a loose bolt of the "V'' shape airbrake bellcrank, named hereafter intermediate control lever. The Left Hand (LH) wing lever also presented, to a lesser extent, a loose bolt. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective June 5, 2008. As of February 1, 2008 (73 FR 3623), the Director of the Federal Register approved the incorporation by reference of Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE-059/SZD-50-3/2007 "PUCHACZ,'' dated October 15, 2007, listed in this AD.
2018-18-15: We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211- Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211-Trent 892B-17, and RB211-Trent 895-17 turbofan engines. This AD was prompted by low-pressure compressor (LPC) case A-frame hollow locating pins that may have reduced integrity due to incorrect heat treatment. This AD requires replacement of the LPC case A-frame hollow locating pins. We are issuing this AD to address the unsafe condition on these products.
2001-17-02: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, and -800 series airplanes. This action requires repetitive inspections for corrosion or cracking of the keel beam splices, and corrective action, if necessary. This action also provides an optional terminating action for the repetitive inspections. This action is necessary to find and fix corrosion or cracking of the keel beam splices, which could result in failure of the keel beam and consequent failure of the forward fuselage of the airplane. This action is intended to address the identified unsafe condition.
