95-05-03: This amendment supersedes an existing airworthiness directive (AD), applicable to Hamilton Standard 14RF series, 14SF series, and Hamilton Standard/British Aerospace 6/5500/F series propellers, that currently requires a one-time ultrasonic shear wave inspection for cracks in the propeller blade taper bore. This amendment requires initial and repetitive ultrasonic shear wave inspections, and a one-time visual and borescope inspection of the taper bore for corrosion as a terminating action to the ultrasonic shear wave inspections. This amendment is prompted by reports of two incidents where a portion of the propeller blade was lost in flight. The actions specified by this AD are intended to prevent loss of a propeller blade due to cracks initiating in the blade taper bore, that can result in possible aircraft damage, and possible loss of aircraft control.
63-05-02: 63-05-02 SIKORSKY: Amdt. 542 Part 507 Federal Register March 6, 1963. Applies to All S-55 Series Helicopters. Compliance required as indicated. There has been a fatigue fracture of the main rotor blade spar. For this reason, accomplish the following: (a) All S14-10-2000 Series main rotor blades with 975 or more hours' time in service as of the effective date of this AD shall be retired from service within the next 25 hours' time in service. (b) All S14-10-2000 Series main rotor blades with less than 975 hours' time in service as of the effective date of this AD shall be retired from service prior to the accumulation of 1,000 hours' time in service. This directive effective March 6, 1963.
2002-17-01: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Learjet Model 45 airplanes. This action requires pulling the FOOT WARM circuit breaker located on the copilot's circuit breaker panel, and installing a collar on that circuit breaker. This action is necessary to prevent an electrical short circuit between the pilot's and copilot's foot warmers and the composite floorboards, which could result in outgassing of the faceply material of the composite floorboards, and consequent smoke in the cockpit. This action is intended to address the identified unsafe condition.
2023-21-06: The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. As published, two references to an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD in the preamble Background section are incorrect. This document corrects those errors. In all other respects, the original document remains the same.
2002-16-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-100, -200, and -300 series airplanes, that requires various modifications of the airstair (main passenger) door. This action is necessary to prevent failure of the airstair door to open after a landing, which could result in a blocked escape route during an emergency evacuation. This action is intended to address the identified unsafe condition.
86-22-09: 86-22-09 UNIVAIR AIRCRAFT CORPORATION: Amendment 39-5457. Applies to Model (Ercoupe) 415, -C, -CD, -D, -E, -G (all serial numbers), and (Forney) Models F1 and F1A (all serial numbers) airplanes certificated in any category. Compliance: Required within the next 25 hours time-in-service after the effective date of this AD or at the next annual inspection whichever occurs first, unless already accomplished. To prevent possible fuel leakage and loss of engine power, accomplish the following: (a) Visually inspect the fuel line nipple located between the gascolator and the carburetor for cracks, incorrect alignment or over torque and prior to further flight replace as necessary, the nipple from a AN911-2D (aluminum) to a AN911-02 (brass or steel) fitting as described in Univair Aircraft Corporation, Ercoupe Bulletin No. 24A dated August 22, 1986. (b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (c) An equivalent means of compliance with this AD may be used if approved by the Manager, Denver Aircraft Certification Office, Northwest Mountain Region, 10455 East Avenue, Suite 307, Aurora, Colorado 80010. All persons affected by this directive may obtain copies of the document(s) referred to herein upon request to Univair Aircraft Corporation, 2500 Himalaya Road, Aurora, Colorado 80011; or FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106. This amendment becomes effective on November 13, 1986.
2014-05-06 R1: We are revising Airworthiness Directive (AD) 2014-05-06 for Eurocopter Deutschland GmbH Model EC135 and MBB-BK 117C-2 helicopters. AD 2014-05-06 required repetitive inspections of the flight-control bearings, replacing any loose bearings with airworthy flight-control bearings, and installing bushings and washers. This new AD retains the requirements of AD 2014-05-06 but removes the repetitive inspections. The actions of this AD are intended to correct an unsafe condition on these products.
2023-23-01: The FAA is superseding Airworthiness Directive (AD) 2022-01- 05, which applied to certain Airbus Helicopters Model EC130T2 helicopters. AD 2022-01-05 required repetitive visual inspections of the rivets on the rear transmission shaft bearing support, inspections of the local structure, and rivet heads on the left-hand and right-hand sides of the rear transmission shaft bearing support for cracking, missing, loose, or sheared rivets. AD 2022-01-05 also required reporting the results of those inspections and depending on the results, applicable corrective action. Since the FAA issued AD 2022-01- 05, Airbus Helicopters revised its service information to add procedures to improve visual inspections of the rivets on the rear transmission shaft bearing support. This AD was prompted by the determination that certain modified helicopters may have finishing paint applied to the gutter, which could prevent detection of cracks during inspections. This AD also extends the repetitive compliance time interval for certain inspections. This AD continues to require certain actions in AD 2022-01-05 and requires a one-time visual inspection for paint in the gutter area, and removal of paint if necessary, 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.
2023-21-07: The FAA is superseding Airworthiness Directive (AD) 2018-03-13 for certain General Electric Company (GE) Model CT7-5A2, CT7-5A3, CT7- 7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, and CT7-9C3 engines. AD 2018-03-13 required initial and repetitive visual inspections and fluorescent penetrant inspections (FPIs) of the main propeller shaft. This AD was prompted by an in-flight failure of a main propeller shaft on a GE Model CT7-9B engine, resulting in the loss of the propeller. This AD requires initial and repetitive visual inspections, FPIs, and ultrasonic inspections (USIs) of the main propeller shaft. Depending on the results of these inspections, this AD requires replacement of the main propeller shaft. As an optional terminating action to these inspections, this AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate incorporating the tasks and reduced inspection thresholds for the main propeller shaft. The FAA is issuing this AD to address the unsafe condition on these products.
2002-16-12: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that requires revising the Limitations Section of the FAA-approved Airplane Flight Manual to ensure the flightcrew is advised of the proper procedures in the event of uncommanded movement of a spoiler during flight. Such uncommanded movement could result in reduced controllability of the airplane, and consequent significant increased fuel consumption during flight, which could necessitate an in-flight turn-back or diversion to an unscheduled airport destination. This action is intended to address the identified unsafe condition.
