found during compliance with this AD via the Defect Reporting System.
                Note 2:  Removal of lock-wire/safety clips may be required to perform the detailed inspection adequately. Certain methods of locking such as lock-wire which is wrapped (spiral) around the terminal should be removed. The requirement for the disassembly of the turnbuckle is at the discretion of the maintainer.
                Note 3:  Additional guidance, background and references are provided in CASA Airworthiness Bulletin 27-001, ATSB report AE-2012-028 and FAA SAIB
                CE-02-05R1.
Compliance:     For requirement 1: Initial Inspection for cables with 15 years or more TIS, or unknown TIS at the effective date of this AD - Before 1 November 2018.
                For requirement 2: At intervals not to exceed 12 months.
                Note 4:  Where the existing manufacturer's maintenance schedule has a cable inspection interval that is different from 12 months, this interval is acceptable for compliance with this AD providing that the detailed inspection task is considered to be the equivalent to the requirements of this AD.
                Requirement 3: Before further flight after the performance of requirement 1 or 2.
                Requirement 4: Within two working days of the discovery of the defect.
                Note 5:  Where a cable assembly has been previously replaced and with a logbook entry documenting the replacement, this relieves the repetitive inspection of this AD, for that cable only, until such time as that cable assembly has been in service for 15 years.
                This AD commences on 1 November 2017.
Background:     Following multiple reports of cable terminal failures, CASA undertook industry consultation via Notice of Proposed Rule Making (NPRM) 1303 MS Proposed Airworthiness Directive to Mandate Inspection or Retirement of Control Cable Assemblies with Terminals Manufactured from SAE – AISI 303 Se Stainless Steel in 2014.
                As a result of industry feedback received in response to NPRM 1303 MS, CASA issued AD/GENERAL/87 Primary Flight Control Cable Assembly Retirement mandating retirement of control cable assemblies manufactured with terminal fittings made from SAE-AISI 303 Se Stainless Steel with 15 years or more TIS before 1 January 2018.
                Subsequent input from industry as a result of the release of AD/GENERAL/87, as well as additional investigation and risk analysis undertaken by CASA, resulted in CASA issuing PAD/GENERAL/87 Amdt 1 Primary Flight Control Cable Terminals - Detailed Visual Inspections on 31 May 2017. The PAD provided the rationale for enhanced inspection of primary flight control cables rather than mandatory retirement life, offering an acceptable level of safety at a lower material cost to industry.
                Industry feedback to PAD/GENERAL/87 Amdt 1 has been incorporated into the actions detailed in this AD which now require a thorough inspection of the cable terminal fittings that have more than 15 years TIS.
