Emergency Equipment AD/EMY/33 Amdt 1 Emergency Evacuation Slide/Raft 4/2004 Applicability: Air Cruisers Company Emergency Evacuation Slide/Raft System part number 62774, all dash numbers; with the affected slide/raft system identified by the serial numbers specified in Table 1, "Affected Slide/Raft Serial Numbers", of FAA AD 2004-03-01. Note: These Emergency Evacuation Slide/Raft Systems are installed on, but not limited to Boeing 777-200 and -300 series aircraft. Requirement: 1. For slide/raft systems identified by serial number specified in applicability: 1. For slide/raft systems currently installed on aircraft, repack the slide/raft in accordance with the Accomplishment Instructions described in Air Cruisers Company Service Bulletin 777-107-25-06, dated 19 February 1999, and the applicable Air Cruisers Company Folding Procedure P-12054 (for left hand slide rafts), Revision G, or Folding Procedure P-12064 (for right hand slide rafts), Revision G, both Folding Procedures dated 1 February 2002. b. For uninstalled slide/raft systems, repack the slide/raft in accordance with the Accomplishment Instructions described in Air Cruisers Company Service Bulletin 777-107-25-06, and the applicable Air Cruisers Company Folding Procedure P-12054 Revision G, or Folding Procedure P-12064 Revision G. 2. For slide/raft systems serial number 0558 and lower, and not specified in applicability: Repack the slide/raft systems in accordance with the applicable Air Cruiser Company Folding Procedure P-12054 Revision G or P-12064 Revision G. Slide/raft systems identified by serial number specified in applicability or Requirement 2 of this Directive that have already been repacked in accordance with Air Cruisers Company Folding Procedures P-12054 Revision F or P-12064 Revision F, both dated 12 March 1999, as applicable, before the effective date of this Directive, are considered in full compliance with the requirements of Requirement 1 and Requirement 2 of this Directive. Emergency Equipment AD/EMY/33 Amdt 1 (continued) Slide/raft systems identified by serial number specified in applicability or Requirement 2 of this Directive that were repacked in accordance with the original issue of this Directive are considered in compliance with Requirement 1 or Requirement 2 of this Directive. Note: FAA AD 2004-03-01 refers. Compliance: 1. a. Repack within 2 months after 15 April 2004. b. Repack before installation. 2. At the next required normal maintenance schedule of the slide/raft system, but no later than 18 months after 15 April 2004. This Amendment becomes effective on 15 April 2004. Background: The FAA received reports of separation of the lower aspirator during a number of deployments. Failure of the slide/raft to properly inflate could impede the emergency evacuation of passengers in the event of an aircraft emergency. Amendment 1 is issued in response to a new FAA AD, which was prompted by recent information from Air Cruisers Company that modifications have been made which have added new dash numbers to the slide/raft system basic part number. This has affected some of the serial numbers of slide/raft systems listed in previous FAA AD. David Villiers Delegate of the Civil Aviation Safety Authority 4 March 2004 The above AD is notified in the Commonwealth of Australia Gazette on 24 March 2004.
