Emergency Equipment AD/EMY/36 Evacuation Systems - Corroded 6/2008 Shear-Pin Restraints Applicability: Goodrich evacuation systems approved under Technical Standard Orders (TSOs) TSO-C69, TSO-C69a, and TSO-C69b, installed on certain Boeing, McDonnell Douglas and Airbus aircraft as defined in FAA AD 2008-06-27, Tables 1, 2 and 3. Requirement: Perform the actions required by the "Replacement, or Inspection and Corrective Action" section of FAA AD 2008-06-27. Replacements and inspections performed before the effective date of this AD in accordance with the applicable Service Bulletins identified in FAA AD 2008-06-27, Table 4, are acceptable for compliance with the above requirements. Note: FAA AD 2008-06-27 and Goodrich Service Bulletins 25-343 and 25-344 refer. Compliance: As specified in "Compliance Times" section of FAA AD 2008-06-27 but with a revised effective date of 5 June 2008. This Airworthiness Directive becomes effective on 5 June 2008. Background: This Airworthiness Directive is prompted by several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are issuing this Airworthiness Directive to prevent failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and crew during the evacuation.
