2006-16-18 R1 Sandel Avionics Incorporated: Amendment 39-15557. Docket No. FAA-2007-0290; Directorate Identifier 2007-NM-250-AD. \n\nEffective Date \n\n\t(a) This airworthiness directive (AD) is effective July 18, 2008. \n\nAffected ADs \n\n\t(b) This AD revises AD 2006-16-18. \n\nApplicability \n\n\t(c) This AD applies to Sandel Avionics Incorporated (Sandel) Model ST3400 terrain awareness warning system/radio magnetic indicator (TAWS/RMI) units approved under Technical Standard Order(s) C113, C151a, or C151b; as identified in Sandel ST3400 Service Bulletin SB3400-01, Revision B, dated September 15, 2004; as installed on various small and transport category airplanes, certificated in any category, including, but not limited, to the airplane models listed in Table 1 of this AD. \n\n\tTable 1.--Manufacturers/Airplane Models\n\n\nManufacturer\nAirplane model(s)\nAirbus\nA300\nAvions Marcel Dassault - Breguet Aviation (AMD/BA)\nFalcon 10\nBoeing\n727, 737, 747\nBombardier (LearJet)\n24, 35,36, 55\nBritish Aerospace (Operations) Limited\nJetstream Series 3101\nCessna\n208, 208B, 421C; 501, 525, 550, 560, 650, S550\nEmbraer\nEMB-120\nDassault-Aviation\nMystere-Falcon 50, Mystere-Falcon 200\nGulfstream\nG-I, G-1159A (G-III)\nIsrael Aircraft Industries (IAI)\n1124, 1125 Westwind Astra\nMcDonnell Douglas\nDC-10\nPiper\nPA-31T2\nRaytheon\n58; 1900D, 400; A36; BAe.125 Series 800A; HS.125 Series 600A/700A; Hawker 800-XP; 200, 300, 350; A200, B100, B200, B300, C90, C90A, C90B, E90, F90; MU-300-10\nSabreliner\n60 (NA-265-60)\nTwin Commander\n500-A, 695A\nViking Air Limited\nDHC-6\n\nUnsafe Condition \n\n\t(d) This AD results from a report that an in-flight bearing error occurred in a Model ST3400 TAWS/RMI unit configured to receive bearing information from a very high frequency omnidirectional range (VOR) receiver interface via a composite video signal, due to a combination of input signal fault and software error. We are issuing this AD to prevent a bearing error, which could lead to an airplane departing from its scheduled flight path, which could result in a reduction in separation from, and a possible collision with, other aircraft or terrain. \n\nCompliance \n\n\t(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. \n\nInstalling Placard \n\n\t(f) Within 14 days after September 25, 2006 (the effective date of AD 2006-16-18): Install a placard on the TAWS/RMI which states, ''NOT FOR PRIMARY VOR NAVIGATION,'' in accordance with Sandel ST3400 Service Bulletin SB3400-01, Revision B, dated September 15, 2004. \n\nRevising Airplane Flight Manual (AFM) \n\n\t(g) Within 14 days after September 25, 2006: Revise the Limitations section of the applicable AFM to include the following statement: ''Use of ST3400 TAWS/RMI for primary VOR navigation is prohibited unless the indicator has 3.07 or A3.06 software or later.'' This may be done by inserting a copy of this AD into the AFM. \n\nUpdating Software \n\n\t(h) Within 90 days after September 25, 2006, in accordance with Sandel ST3400 Service Bulletin SB3400-01, Revision B, dated September 15, 2004: Field-load the TAWS/RMI with updated software having revision 3.07 (for units having serial numbers (S/Ns) under 2000) or revision A3.06 (for units having S/Ns 2000 and subsequent). Revisions of software later than revision 3.07 or A3.06, as applicable, are considered acceptable for compliance with the requirements of this paragraph. The placard and AFM limitations revision installed as required by paragraphs (f) and (g) of this AD may be removed after the software upgrade required by paragraph (h) of this AD has been accomplished. \n\nParts Installation \n\n\t(i) As of 90 days after September 25, 2006, no person may install, on any airplane, a Model ST3400 TAWS/RMI unit, unless it has been modified in accordance with Sandel ST3400 Service Bulletin SB3400-01, Revision B, dated September 15, 2004. \n\nAlternative Methods of Compliance (AMOCs) \n\n\t(j)(1) The Manager, Los Angeles Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. \n\t(2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. \n\nMaterial Incorporated by Reference \n\n\t(k) You must use Sandel ST3400 Service Bulletin SB3400-01, Revision B, dated September 15, 2004, to do the actions required by this AD, unless the AD specifies otherwise. \n\t(1) The Director of the Federal Register previously approved the incorporation by reference of Sandel ST3400 Service Bulletin SB3400- 01, Revision B, dated September 15, 2004 on September 25, 2006 (71 FR 48461, August 21, 2006). \n\t(2) For service information identified in this AD, contact Sandel Avionics Incorporated (Sandel), 2401 Dogwood Way, Vista, California, 92081. \n\t(3) You may review copies of the service information that is incorporated by reference at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the National Archives and Records Administration (NARA).
