2006-07-16: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires replacing all domed anchor nuts at all attachment locations of the upper fuel access panels of the center wing in the wet bay location with new nuts. This AD results from reported cases of corroded dome anchor nuts at the attachment locations of the upper surface of the fuel access panel of the center wing. We are issuing this AD to prevent corrosion or perforation of domed anchor nuts, which could result in arcing and ignition of fuel vapor in the center wing fuel tank during a lightning strike and consequent explosion of the fuel tank.
99-19-35: This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace BAe Model ATP airplanes, that requires repetitive tests for the serviceability of the nose landing gear compensator; and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent a nose wheel shimmy, which could lead to the collapse of the nose landing gear during landing.
51-07-01: 51-07-01 NAVION: Applies to All Models Having Serial Numbers 1789 Through 2019; 2021 Through 2026; 2028 Through 2142; 2144 Through 2169; 2171 Through 2177; and 2180. To be accomplished as indicated below. It has been found that on some of these airplanes throttle housing slippage has occurred at the point where the cable housing is swaged to the ferrule at the instrument panel end. This slippage can result in erratic throttle operation. An inspection of these controls for evidence of housing slippage must be made not later than March 5, 1951. Any control showing evidence of slippage shall be replaced immediately. It has been found that housing slippage may be caused by the inner shaft in the control head striking the end of the housing when the throttle is moved to the full open position. To prevent such occurrence, a special stop nut must be installed on the throttle shaft in place of the existing jam nut. This special nut, which will prevent the inner shaft from striking the end of the housing, is being furnished by the Ryan Co. and must be installed by July 15, 1951. (Ryan Field Service Bulletin No. 9, dated September 1, 1950, covers this same subject.)
98-14-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 series airplanes. This action requires repetitive inspections to detect cracks in the forward canted frames between fuselage frames 47a and 48 from stringer (STGR) 41 to STGR 43; and temporary repair, or replacement of the forward canted frame with a new frame, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to detect and correct cracking in the forward canted frames, which could result in failure of the forward canted frame, and consequent reduced structural integrity of the airplane.
2006-07-10: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 727 airplanes. That AD currently requires repetitive visual inspections for cracking of the forward entry doorway forward frame and repair if necessary. That AD also provides an optional modification that constitutes terminating action. This new AD requires adding new post-repair and post- modification inspections for previously repaired or modified airplanes, mandating the optional modification, and adding airplanes to the applicability of the AD. This AD results from reports of cracking of the forward entry doorway forward frame of airplanes previously modified. We are issuing this AD to prevent the loss of the structural integrity of the forward entry doorway due to cracking of the frame at Body Station 303.9, and consequent cracking of the fuselage skin and rapid decompression of the airplane.
2003-03-18: This amendment adopts a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. This AD requires you to perform control column sweep and stop bolt inspections to verify full elevator travel to the primary up and down stops and that the stop bolt length is not excessive, re-rig the elevator control system if the airplane does not pass the control column sweep and stop inspections, and do a more detailed inspection at a later time if the airplane does pass the inspection. This AD also requires you to report the results of certain inspections. This AD is the result of recent ground testing and a review of the rigging procedures of a Raytheon Beech Model 1900D airplane, which reveals that the elevator control system could be mis-rigged to restrict elevator travel if current maintenance procedures are not properly followed. In these instances, it may appear to the crew that they have full elevator control column movement. However, the elevator may not have full travel. Such restricted travel may remain undetected until the airplane is operated in a loading condition that requires full elevator authority to control the pitch. The actions specified by this AD are intended to detect and correct any mis-rigged elevator control system, which could lead to insufficient elevator control authority and loss of control of the airplane.
2002-04-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 series airplanes and A320-200 series airplanes, that requires repetitive inspections to detect loose or missing rivets in specified areas of the door frames of the overwing emergency exits and corrective action, if necessary. This AD also requires measurement of the grip length of all rivets in the specified areas and corrective action, if necessary, which terminates the repetitive inspections. This amendment is prompted by mandatory continuing airworthiness information from a foreign airworthiness authority. The actions specified by this AD are intended to detect and correct loose or missing rivets or discrepant rivets, which could lead to reduced structural integrity of the overwing emergency exit door frames. This action is intended to address the identified unsafe condition.
2006-07-12: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires a one-time inspection for scribe lines and cracks in the fuselage skin at certain lap joints, butt joints, external repair doublers, and other areas; and related investigative/ corrective actions if necessary. This AD results from reports of fuselage skin cracks adjacent to the skin lap joints on airplanes that had scribe lines. Scribe line damage can also occur at many other locations, including butt joints, external doublers, door scuff plates, the wing-to-body fairing, and areas of the fuselage where decals have been applied or removed. We are issuing this AD to prevent rapid decompression of the airplane due to fatigue cracks resulting from scribe lines on pressurized fuselage structure.
68-03-04: 68-03-04 VICKERS: Amendment 39-551. Applies to Viscount Models 744, 745D, and 810 Series airplanes. Compliance required as indicated, unless already accomplished To detect cracking of the upper and lower torsion link hinge pins of the nose landing gear, accomplish the following: (a) For airplanes with pre Modification D.3045 (700 Series) and FG.1861 (800 Series) hinge pins with less than 4,000 landings on the effective date of this AD, before the accumulation of 5,000 landings, and thereafter at intervals not to exceed 1,000 landings from the last inspection until the accumulation of 10,000 landings and thereafter at intervals not to exceed 500 landings from the last inspection, comply with paragraph (d). (b) For airplanes with pre Modification D.3045 (700 Series) and FG.1861 (800 Series) hinge pins with 4,000 or more landings but less than 9,000 landings on the effective date of this AD, within the next 1,000 landings after the effective date of this AD and thereafter at intervals not to exceed 1,000 landings from the last inspection until the accumulation of 10,000 landings and thereafter at intervals not to exceed 500 landings, comply with paragraph (d). (c) For airplanes with pre Modification D.3045 (700 Series) and FG.1861 (800 Series) hinge pins with 9,000 or more landings on the effective date of this AD, within the next 500 landings or before the accumulation of 10,000 landings, whichever occurs later, and thereafter at intervals not to exceed 500 landings from the last inspection, comply with paragraph (d). (d) Remove pre Modification D.3045 (700 Series) and FG.1861 (800 Series) hinge pins and inspect for cracks using Magnaflux examination or an equivalent approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Region, in accordance with British Aircraft Corporation (BAC) Preliminary Technical Leaflets (PTLs) No. 233, Issue 3 (700 Series) and No. 99, Issue 3 (800 Series), or later ARB-approved issued, or an equivalent approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Region. (e) If cracked hinge pins are found during the inspections required by paragraphs (a), (b) and (c), before further flight, replace the pins with serviceable pins of the same part number and comply with the inspection requirements of paragraph (a), or replace the pins with Modification D.3045 (700 Series) and FG.1861 (800 Series) pins. (f) The repetitive inspections required by paragraphs (a), (b) and (c) may be discontinued on those hinge pins replaced by Modification D.3045 (700 Series) and FG.1861 (800 Series) pins. (g) Upon request of the operator, an FAA maintenance inspector, subject to prior approval by the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator. This amendment becomes effective March 7, 1968.
98-05-11: This amendment adopts a new airworthiness directive (AD), applicable to all Bombardier Model CL-215-6B11 (CL-215T) series airplanes. This action requires either replacement of the switching valve-to-rear inlet case sealing air tube assembly with a tube assembly that includes an integral fire detector (intercompressor case [ICC] fire detector loop), and modification of the nacelle fire detection system; or modification of the No. 5 bearing air system. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to detect internal engine fire within the ICC; or to prevent air/oil from leaking into the ICC, which could result in such fire.
