97-02-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Fokker Model F28 Mark 0100 series airplanes. It requires a one-time inspection to verify the correct routing and tension of the flight control lock cables and the elevator control cables, and rerouting or adjustment of the tension of these cables, if necessary. This amendment is prompted by a report indicating that an inspection for correct routing and tension of those cables may not have been accomplished during modification of the airplanes at the factory. The actions specified by this AD are intended to prevent incorrect routing and tension of the flight control lock cables and the elevator control cables, which could result in inadvertent disconnection of those cables, and consequent reduced controllability of the airplane.
96-22-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Shorts Model SD3-60 and SD3-SHERPA series airplanes, that requires a one-time inspection to detect cracks and/or corrosion of the gland nut on the shock absorber of the main landing gear (MLG), and follow-on actions. This amendment also requires repair or replacement of any cracked/corroded gland nut with a new nut. This amendment is prompted by a report indicating that, due to stress corrosion and cracking of the gland nut on the shock absorber, the MLG collapsed on an in-service airplane. The actions specified by this AD are intended to detect and correct such stress corrosion or cracking in a timely manner and consequent reduced structural integrity of the gland nut, which could result in separation of the shock absorber cylinder from the MLG shock absorber body and, consequently, lead to the collapse of the MLG during landing.
2004-20-07: This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) model helicopters that requires certain inspections of the main rotor yoke (yoke) for a crack, fretting, or buffer deterioration.

2004-19-04: The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce plc (RR) RB211-22B, RB211-524, and RB211-535 series turbofan engines. This AD requires revising the Time Limits Manual for RR RB211-22B, RB211-524, and RB211-535 series turbofan engines. These revisions include required enhanced inspection of selected critical life-limited parts at each piece-part exposure. This AD results from the need to require enhanced inspection of selected critical life-limited parts of RB211-22B, RB211-524, and RB211-535 series turbofan engines. We are issuing this AD to prevent failure of critical life-limited rotating engine parts, which could result in an uncontained engine failure and damage to the airplane.
96-13-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F28 series airplanes, that requires replacement of junction fittings of the horizontal stabilizer with improved fittings. For certain airplanes, this amendment also requires replacement of the drive-fitting bushings and bolts of the horizontal stabilizer with improved bushings and bolts. This amendment is prompted by reports of stress corrosion cracking in a junction fitting lug of the horizontal stabilizer. The actions specified by this AD are intended to prevent such cracking, which could result in failure of a lug and uncommanded movement of the horizontal stabilizer. This condition, if not corrected, could result in reduced controllability of the airplane.

Docket No. 90-NM-116-AD. \n\n\tApplicability: Model 737 series airplanes, line numbers 001 through 519, certificated in any category. \n\n\tCompliance: Required as indicated, unless previously accomplished. \n\n\tTo prevent rapid decompression of the airplane, accomplish the following: \n\n\tA.\tWithin the next 3,000 cycles after the effective date of this AD, unless previously accomplished within the last 3,000 cycles, and thereafter at intervals not to exceed 6,000 cycles, perform an ultrasonic inspection for delamination of the window belt skin doubler from the fuselage skin, in accordance with Boeing Service Bulletin 737-53-1078, Revision 1, dated September 25, 1986, or Revision 2, dated April 19, 1990. \n\n\tB.\tIf delamination is found as a result of the inspections required by paragraph A. of this AD, prior to further flight, conduct a high frequency eddy current (HFEC) inspection for cracks of the skin around the countersunk fasteners in thearea of delamination and common to the window forging, in accordance with Boeing Model 737 Non-destructive Test (NDT) Manual Document D6-37239, Part 6, Subject 53-30-05, and repeat thereafter at intervals not to exceed 6,000 cycles. \n\n\tC.\tIf cracks are detected as a result of the inspection required by paragraph B. of this AD, prior to further flight, repair cracking and delamination in accordance with Boeing Service Bulletin 737-53-1078, Revision 1, dated September 25, 1986, or Revision 2, dated April 19, 1990. Further HFEC inspections for cracks under the repairs are not required. \n\n\tD.\tIf delamination is found as a result of the inspection required by paragraph A. of this AD, perform the terminating modification in accordance with Boeing Service Bulletin 737- 53-1078, Revision 1, dated September 25, 1986, or Revision 2, dated April 19, 1990, prior to the accumulation of 40,000 cycles or within the next 24 months, whichever occurs later, after discovery of the delamination. Accomplishment of this modification constitutes terminating action for the inspections required by paragraphs A. and B. of this AD. \n\n\tE.\tAn alternative method of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate. \n\n\tNOTE: The request should be forwarded through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Seattle ACO. \n\n\tF.\tSpecial flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. \n\n\tAll persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Boeing Commercial Airplane Group, P.O. Box 3707, Seattle, Washington 98124. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 1601 Lind Avenue S.W., Renton, Washington. \n\n\tAirworthiness Directive 91-07-04 supersedes AD 89-15-05, Amendment 39-6264. \n\n\tThis amendment (39-6933, AD 91-07-04) becomes effective on April 15, 1991.
2022-18-01: The FAA is superseding Airworthiness Directive (AD) 2017-10- 24, which applied to certain Airbus SAS Model A330-200 series airplanes, Model A330-200 Freighter series airplanes, and Model A330- 300 series airplanes; AD 2018-23-14, which applied to certain Airbus SAS Model A330-200 series airplanes, Model A330-200 Freighter series airplanes, and Model A330-300 series airplanes; and AD 2021-05-12, which applied to certain Airbus SAS Model A330-200 Freighter series airplanes. AD 2017-10-24, AD 2018-23-14, and AD 2021-05-12 require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD revises the applicability by adding airplanes. This AD continues to require the actions in AD 2018-23-14 and AD 2021-05-12, and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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.
