2021-11-08: The FAA is superseding Airworthiness Directive (AD) 2014-25-04 for all Pilatus Aircraft Ltd. (Pilatus) Model PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/ B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 airplanes. AD 2014-25-04 required incorporating revised airworthiness limitations into the aircraft maintenance manual (AMM) for your FAA- approved maintenance program. This AD requires incorporating new airworthiness limitations and an eddy current inspection of each fuselage wing fitting if an earlier version of the service information was accomplished. This AD was prompted by a determination that the new life limits, revised airworthiness limitations, and new inspection procedures are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
47-30-05: 47-30-05 AERONCA: (Was Service Note 2 of AD-759-3 and Service Note 2 of AD-761- 3.) Applies to Models 7AC and 11AC. Inspection required not later than September 15, 1947, and each 50 hours thereafter on Model 7AC airplanes having serial numbers prior to No. 7AC-6797 and Model 11AC airplanes having serial numbers prior to No. 11AC-1697. Due to difficulties in the manufacture of the exhaust stacks for these airplanes, it is necessary to inspect the stack "Y" junction for evidence of failure or deterioration. This inspection should be accomplished as follows: A. Initial inspection (not later than September 30, 1947). The exhaust stacks on these airplanes should be removed from the airplane and checked visually in the vicinity of the "Y" junction for evidence of burning or flaking, tapped with a hammer for evidence of soft spots, and inspected to determine whether the stack is obstructed in any way. B. Periodic inspection (each 50 hours). The exhaust stacks should be reinspected visually in the vicinity of the "Y" junction by removing the cabin and carburetor heater muffs each 50 hours of engine operation. (This information is also contained in Aeronca Service Helps and Hints No. 25 dated May 13, 1947.)
97-17-05: This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney Canada PW100 series turboprop engines. This action requires a visual inspection of the two gas generator case drain ports to ensure that they are connected to drain lines or capped in accordance with the applicable aircraft installation configuration. This amendment is prompted by a report of a nacelle fire. The actions specified in this AD are intended to prevent a nacelle fire caused by fluid leaking from the gas generator case drain ports.
97-17-03: This amendment supersedes Airworthiness Directive (AD) 97-13-11, which currently requires inspecting the 1/4-inch and 5/16-inch bolt hole areas on the lower spar caps for fatigue cracking on Ayres S2R series airplanes, and replacing any lower spar cap if fatigue cracking is found. That AD resulted from an accident on an Ayres S2R series airplane where the wing separated from the airplane in flight. AD 97-13-11 incorrectly references the Ayres Model S2R-R1340 airplanes as Model S2R-1340R. This AD requires the same actions as AD 97-13-11, but corrects the designation of the Model S2R-R1340 airplanes. The actions specified by this AD are intended to detect fatigue cracking of the lower spar caps, which, if not corrected, could result in the wing separating from the airplane with consequent loss of control of the airplane. The incorporation by reference of certain publications listed in the regulations was previously approved by the Director of the Federal Register as ofJuly 10, 1997 (62 FR 36978). Comments for inclusion in the Rules Docket must be received on or before October 17, 1997.
96-05-01: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-80 series airplanes, that currently requires inspection and replacement of certain suspect horizontal stabilizer primary trim motors. That AD was prompted by an analysis which revealed that certain incorrectly manufactured motor shafts could fail prematurely and, in turn, cause the primary trim motor to fail. The actions specified in that AD are intended to prevent such failures of the primary trim motor, which could ultimately result in reduced controllability of the airplane. This amendment expands the applicability of the existing AD to include additional affected airplanes.
2021-11-05: The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by reports of an oil leak from the main gearbox (MGB) during engine start up. This AD requires modifying and performing subsequent repetitive function testing of the MGB emergency lubrication (EMLUB) system as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
69-17-03: 69-17-03 GENERAL ELECTRIC: Amdt. 39-824. Applies to General Electric Models CT58-100-1, CT58- 100-2, CT58-110-1, CT58-110-2, CT58-140-1, CT58-140-2, T58-GE-1 and T58-GE-5 engines, installed in Boeing Vertol 107 and Sikorsky S61 and S62 aircraft. To prevent failures of first and second stage turbine rotor discs remove from service General Electric part numbers listed below with more than 10,100 cycles at the time of receipt of this telegram, unless already accomplished. STAGE 1 DISCS STAGE 2 DISCS 278D978P002 278D979P002 37D400498P101 37D400499P101 37D400010P101 37D400004P102 37D400227P101 37D400228P102 37D400307P101 4002T96P01 4002T17P01 For the purposes of this airworthiness directive a cycle is considered as any engine operating sequence involving engine start, at least one acceleration to a power required for takeoff and shutdown. Since it was found that immediate corrective action was required, notice and public procedure thereon was impracticable and contrary to the public interest and good cause existed for making the airworthiness directive effective immediately as to all known U.S. operators of Boeing Vertol 107 and Sikorsky S61 and S62 aircraft with General Electric Engine Models CT58-100-1, CT58-100-2, CT58-110-1, CT58-110-2, CT58-140-1, CT58- 140-2, T58-GE-1 and T58-GE-5, by individual telegrams dated August 12, 1969. These conditions still exist and the airworthiness directive is hereby published in the FEDERAL REGISTER as an amendment to Section 39.13 of Part 39 of the Federal Aviation Regulations to make it effective as to all persons. This amendment becomes effective upon publication in the FEDERAL REGISTER for all persons except those to whom it was made effective immediately by telegram dated August 12, 1969.
2021-11-14: The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by reports of failed nose landing gear (NLG) retraction actuators during the acceptance test procedures on the ground on the final assembly line. This AD requires depending on the helicopter configuration, various modifications, installation checks, inspections of the NLG and main landing gear (MLG) retraction actuators and of the plungers of the NLG and MLG up down lock actuators, and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
2004-05-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that requires an inspection of the clearance space between the fuel quantity indication (FQI) probes located in the center fuel tank and the adjacent structure, an inspection of the position of the support bracket for each probe, an inspection of the part number for each support bracket, and corrective action if necessary. The actions specified by this AD are intended to prevent the loss of FQI of the center fuel tank, and electrical arcing between the FQI probes and the adjacent structure in the event that the airplane is struck by lightning. Such arcing could create a potential ignition source within the center fuel tank and an increased risk of a fuel tank explosion and fire. This action is intended to address the identified unsafe condition.
2021-11-11: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 Freighter series airplanes. This AD was prompted by a report indicating occurrences of broken brackets of the support structure of the halon fire extinguishing bottle 4005WX; investigation showed that fatigue cracks initiated in the attachment brackets at the cross beams due to dynamic loading, and in some cases propagated in the struts. This AD requires replacing the support brackets of the 4005WX fire extinguisher bottle with reinforced support brackets, and replacing the strut assembly at the affected location, 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.
