60-23-01: 60-23-01\tBOEING: Amdt. 216 Part 507 Federal Register November 4, 1960. Applies to the following 707-100 Series aircraft: Serial Numbers 17586 through 17591, 17628 through 17651, 17658 through 17672, 17696 through 17702, and 17925 through 17927. \n\n\tCompliance required within 2,500 hours' time in service after effective date.\n \n\tIncidents have occurred of the engine start lever slipping toward the "OFF" position causing engine flame-out. One such incident occurred during takeoff. These incidents were caused by insecure placement of the start lever in the "idle" position. In addition, inspections have disclosed the presence of incorrect parts and improper installations on some airplanes.\n \n\tAlso, in the present starting ignition system, on some airplanes, the igniter plug fires during initial engine rotation. This has caused combustion chamber explosions when fuel vapors were present. \n\n\tTo correct the above unsatisfactory conditions, the following modifications or FAA approved equivalents and inspections are required: \n\n\tI.\tModify and inspect the start lever system as follows: \n\n\t\ta.\tMachine an additional slot at the start position of the start lever latch in each of the start lever guides as shown in Fig. 1 of Boeing Service Bulletin 369 dated April 15, 1959. \n\n\t\tb.\tAscertain that the control stand start lever spacers, P/N 66-19067-1 and -2, and lever guide fillers P/N 66-9256-3, are correctly installed as follows:\n\n\t\t\t(1)\tThe two outboard spacers must be P/N 66-19067-1 and -2 and installed in accordance with Boeing Drawing 65-1795. (Boeing 707 Parts Catalog Fig. 25-2-11 is in error in calling for P/N 66-9256-1 and -2 for Items 28 and 33. Correct P/N's are 19067-1 and -2 as indicated above.)\n\n\t\t\t(2)\tThe middle lever guide filler, P/N 66-9256-3, must be installed with the wide section at the top and not at the bottom. (Item 17 in Fig. 75-2-11 of Boeing 707 Parts Catalog is incorrect in that it shows the wide section at the bottom.)\n \n\t\tc.Ascertain that the start lever detents have a minimum distance of 0.53 inch between the stop strap and the idle detents in accordance with Bulletin 369.\n \n\t\td.\tAfter reinstallation of the start levers, ascertain that the start lever system is properly rigged as covered in Chapter 76 Boeing 707-100 Series Maintenance Manual. This applies only to airplanes which require removal of the start lever detents for machining the slot. \n\n\tII.\tModify the starting ignition system as follows: \n\n\t\ta.\tRemove the jumper wire between the "COMMON" terminal and "NO" terminal of each engine start lever switch (S192, S193, S194, S195).\n \n\t\tb.\tInstall a wire from the "ON" contact flight start and control switches (S188, S189, S190 and S191) on the pilot's overhead panel to the corresponding engine ignition circuit breaker bus on the P6 circuit breaker panel. Remove the No. 18 jumper wire between the flight start and ground start terminals of the engine start and control switch. Boeing Service Bulletin No. 195 (R-1) dated July 8, 1959, and Supplement No. 195 (R-1)A dated August 4, 1959, covers these changes.\n \n\tThis directive shall become effective December 6, 1960.

D. \n\n\tThis amendment becomes effective June 30, 1978.
2010-06-04: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Cracks have been found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with General Electric engines. Investigation of these findings indicates that this problem is likely to affect aircraft of this type design with other engine installations. This condition, if not corrected, can lead to reduced strength [structural integrity] of the pylon primary structure. * * * * * The unsafe condition is reduced structural integrity of the pylon primary structure, which could cause detachment of the engine from the fuselage. We are issuing this AD to require actions to correct the unsafe condition on these products.
2002-23-20: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 900EX and Mystere Falcon 900 series airplanes, that requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair, if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action, if necessary. This amendment also requires revision of the Airplane Flight Manual. 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 jamming of the flap jackscrews during the approach to landing, which could result in inability to move the flaps or an asymmetric flap condition, and consequent reduced controllability of the airplane. DATES: This correction is effective May 4, 2010. The effective date of AD 2002-23-20 remains January 3, 2003.

Other damage may be repaired without blade removed in accordance with the applicable Hamilton Standard instructions.\n \n\t(b)\tSurface-treated blades as classified in Hamilton Standard Bulletin No. 596B shall be inspected in accordance with the applicable Hamilton Standard Bulletins and Service Manuals.\n\n\t\t(1)\tBlades with visual evidence of bending, twisting, or other damage shall be removed before further flight and submitted to Hamilton Standard for repair. A complete description of the circumstances surrounding the incident plus all available alignment records shall accompany the blade, since such details will determine the extent of the repair required.\n \n\t\t(2)\tBlades with no visual evidence of bending, twisting, or other damage shall be treated as follows: \n\n\t\t\t(i)\tIf the applicable alignment gage is available, measure alignment and disposition blades in accordance with Hamilton Standard Service Bulletin No. 602A.\n \n\t\t\t(ii)\tIf an alignment gage is not available, measure propeller track. If track is beyond the tolerance specified in Table II of Hamilton Standard ServiceBulletin No. 596A, the propeller shall be removed from service immediately. If track is within limits, the propeller may be continued in service for a period not to exceed 50 hours' time in service before the face alignment check prescribed in (i) is conducted.\n \n\t(Hamilton Standard Service Bulletins Nos. 596, 596A, 596B, and 602A cover this same subject.)\n \n\tThis supersedes AD 59-17-03.\n \n\tThis directive effective March 1, 1964.
58-01-04: 58-01-04 HELIO: Applies to Model H-391B Aircraft, Serial Numbers 003 to 063 Inclusive. Several aileron-interceptor actuator bellcranks have been found to be cracked. Accordingly, the following inspection and replacement programs are required as indicated. Compliance required within the next 100 hours. Visually inspect the aileron-interceptor actuator bellcranks at the attachment of the control cables. Cracked bellcranks must be replaced. (Helio Service Bulletin No. 16 covers this subject.)
2021-25-02: The FAA is superseding Airworthiness Directive (AD) 2014-16- 16, which applied to all Embraer S.A. Model ERJ 190-100 STD, -100 LR, - 100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2018-19-28, which applied to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. AD 2014-16-16 required, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitive retorquing of those fittings. AD 2018-19-28 required modification of the attaching parts of the pylon lower link fittings. This AD continues to require those actions, and also requires application of a lower torque value, inspection of certain shear pins and replacement if necessary, and revised compliance times for the modification; as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
