2000-15-15: This amendment supersedes an existing airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-9, Model MD-90-30, Model 717-200, and Model MD-88 airplanes, that currently requires inspecting the general condition of the jackscrew assembly and the area around the jackscrew assembly to detect the presence of metal shavings and flakes. This amendment also requires inspecting for metallic particles in the lubrication for the jackscrew assembly of the horizontal stabilizer and surrounding area to detect any discrepancy; follow-on actions; and corrective actions, if necessary. This amendment is prompted by numerous reports from operators that indicate instances of metallic shavings in the vicinity of the jackscrew assembly and gimbal nut of the horizontal stabilizer. The actions specified in this AD are intended to prevent loss of pitch trim capability due to excessive wear of the jackscrew assembly of the horizontal stabilizer, which could result in reduced controllability of the airplane.\n\n\tThe incorporation by reference of Boeing Alert Service Bulletin DC9-27A362, Revision 02, dated March 30, 2000; Boeing Alert Service Bulletin MD90-27A034, Revision 02, dated March 30, 2000; and Boeing Alert Service Bulletin 717-27A0002, Revision 02, dated March 30, 2000; as listed in the regulations; is approved by the Director of the Federal Register as of August 23, 2000.\n\n\tThe incorporation by reference of Boeing Alert Service Bulletin DC9-27A362, dated February 11, 2000; Boeing Alert Service Bulletin MD90-27A034, dated February 11, 2000; and Boeing Alert Service Bulletin 717-27A0002, dated February 11, 2000; as listed in the regulations; was approved previously by the Director of the Federal Register as of March 6, 2000 (65 FR 10379, February 28, 2000).\n\n\tComments for inclusion in the Rules Docket must be received on or before October 10, 2000.
2009-23-10: The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 737-300, -400, and -500 series airplanes. The existing AD currently requires inspecting to determine if certain carriage spindles are installed, repetitive inspections for corrosion and indications of corrosion on affected carriage spindles, and if necessary, related investigative and corrective actions. The existing AD also provides optional terminating action. For certain airplanes, this new AD would reinstate the requirements of the existing AD. This AD results from the exclusion of certain carriage spindles from the requirements of the existing AD, and additional reports of corrosion found on carriage spindles that are located on the outboard trailing edge flaps. We are issuing this AD to detect and correct corrosion of the carriage spindle, which could result in fracture. Fracture of both the inboard and outboard carriage spindles, in the forward ends through the large diameters, on a flap, could adversely affect the airplane's continued safe flight and landing. \n\nDATES: This AD becomes effective November 24, 2009. \n\tThe Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 24, 2009. \n\tOn August 5, 2008 (73 FR 42259, July 21, 2008), the Director of the Federal Register approved the incorporation by reference of a certain other publication listed in the AD. \n\tWe must receive any comments on this AD by December 24, 2009.
2009-12-02: The FAA is superseding an existing airworthiness directive (AD), which applies to the airplanes identified above. That AD currently requires revising the FAA-approved maintenance program to include a new airplane maintenance manual task that specifies a detailed inspection after each ram air turbine (RAT) retraction. That existing AD also currently requires, for certain airplanes, a one-time inspection to detect breaks in the bottom flange fitting of the RAT and corrective actions, if necessary; for certain airplanes, an adjustment of the ejection jack; and, for certain other airplanes, replacement of the aluminum part with an improved steel part. This AD also continues to require certain actions for additional airplanes and revising the FAA-approved maintenance program to include procedures for replacing the RAT swivel coupling fork fitting with a new steel part only. This AD results from a report that an additional swivel coupling of the RAT yoke fitting was found cracked during the accomplishment of the requirements of the existing AD. We are issuing this AD to prevent misrigging of the ejection jack of the RAT and to ensure removal of any RAT yoke fitting made from aluminum material. Such conditions could result in a broken or cracked swivel coupling and consequent failure of the RAT yoke fitting, which could result in the loss of RAT function and possible loss of critical flight control systems in the event of certain emergency situations.

95-08-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that requires installation of new case drain pipes and an additional fairlead support for the hydraulics case drain line in the rear spar area of the engine/nacelle. This amendment is prompted by reports of fatigue failure of the case drain line in the hydraulics system. The actions specified by the proposed AD are intended to prevent the loss of main system hydraulics as a result of lack of support against vibration and subsequent fatigue failure of the case drain line for the hydraulics system.
2006-17-07: The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 turbofan engines. That AD currently requires initial and repetitive visual inspections for fretting and fluorescent magnetic particle inspections (FMPI) for cracking in the area of the tierod holes on 8th stage high pressure compressor (HPC) front hubs (from here on, referred to as HPC front hubs) that have operated at any time with PWA 110-21 coating. This AD requires either replacing HPC front hubs and HPC disks that have operated at any time with PWA 110-21 coating and that operated in certain engine models, or, visually inspecting and FMPI for cracking of those parts and re-plating them if they pass inspection. This AD also requires adding JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, - 11, -15, -15A, -17, -17A, -17R, and -17AR engines to the applicability. This AD results from an investigation by PW, which concluded that any HPC front hub or HPC diskcoated with PWA 110-21 that ever operated on JT8D-15, -15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and - 219 turbofan engines, could crack before reaching their published life limit. We are issuing this AD to prevent a rupture of an HPC front hub or an HPC disk that could result in an uncontained engine failure and damage to the airplane.
2009-23-03: We are adopting a new airworthiness directive (AD) to supersede AD 2006-24-11, which applies to certain Hawker Beechcraft Corporation (HBC) (Type Certificate previously held by Raytheon Aircraft Company) Models 1900, 1900C, and 1900D airplanes. AD 2006-24- 11 currently requires you to repetitively inspect the forward, vertical, and aft flanges of both the left and right wing rear spar lower caps for cracks, repair any cracks found, and report the inspection results to the manufacturer. Since we issued AD 2006-24-11, the manufacturer has developed a modification kit to install on the wing rear spar lower caps that will terminate the 200-hour repetitive inspection required in AD 2006-24-11. Consequently, this AD requires installing the new modification kits on the wing rear spar lower caps and terminates the repetitive inspections required in AD 2006-24-11 when the kits are installed. We are issuing this AD to prevent fatigue cracks in the wing rear spar lower caps, which couldresult in fatigue failure of the wing rear spar lower caps. A rear spar failure could result in complete wing failure and the wing separating from the airplane.
