The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.\n\n![](image.001.png)  \n\nEmergency Equipment\n\nAD/EMY/33\n\nAmdt 1\n\n  \nEmergency Evacuation Slide/Raft 4/2004\n\nApplicability: 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.\n\nNote: These Emergency Evacuation Slide/Raft Systems are installed on, but not limited to Boeing 777-200 and -300 series aircraft.\n\nRequirement: 1. For slide/raft systems identified by serial number specified in applicability:\n\n    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.\n\n    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.\n\n2. For slide/raft systems serial number 0558 and lower, and not specified in applicability:\n\nRepack the slide/raft systems in accordance with the applicable Air Cruiser Company Folding Procedure P-12054 Revision G or P-12064 Revision G.\n\nSlide/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.\n\nEmergency Equipment\n\nAD/EMY/33 Amdt 1 (continued)\n\nSlide/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.\n\nNote: FAA AD 2004-03-01 refers.\n\nCompliance: 1. a. Repack within 2 months after 15 April 2004.\n\nb. Repack before installation.\n\n2. At the next required normal maintenance schedule of the slide/raft system, but no later than 18 months after 15 April 2004.\n\nThis Amendment becomes effective on 15 April 2004.\n\nBackground: 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.\n\nAmendment 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.\n\n![Signature of David Villiers, Delegate of the Civil Aviation Safety Authority.](image.002.png)  \n\nDavid Villiers\n\nDelegate of the Civil Aviation Safety Authority 4 March 2004\n\n![](image.001.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 24 March 2004.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.

(Applicability; Requirement.)\n- It applies to Air Cruisers slide/raft system part number 62774 with particular serial numbers listed in the FAA AD 2004-03-01, and additionally to slide/raft units with serial numbers 0558 and lower that were not already listed. (Applicability; Requirement 2.)\n- The work must be done according to the Air Cruisers Service Bulletin 777-107-25-06 and the appropriate Folding Procedure P-12054 (left-hand) or P-12064 (right-hand), Revision G. If units were already repacked under Folding Procedure Revision F before the effective date, they are taken to be compliant. (Requirement; Note.)\n- Timing: installed units must be repacked within two months after 15 April 2004; uninstalled units must be repacked before installation; units covered only by Requirement 2 must be repacked by the next normal maintenance cycle but no later than 18 months after 15 April 2004. (Compliance.)\n\n**Who it affects\n\n- Aircraft operators and owners that have Air Cruisers slide/raft systems of the specified part number and serial numbers (for example, many Boeing 777-200/-300 aircraft). (Applicability.)\n- The maintenance organisations or personnel who perform repacking under the manufacturer's folding procedures and the service bulletin. (Requirement.)\n\n**Why it matters (stated purpose and practical test)\n\n- Stated purpose: the FAA reported that the lower aspirator has separated on some deployments, causing inflation failures that could impede evacuation. The AD is intended to correct that unsafe condition by ensuring repacking is done to the specified procedures. (Background.)\n\n- Practical effects and trade-offs:\n  - Who pays: the aircraft operator bears the direct costs (labour, maintenance slot time, possible spare unit handling) to repack or to have a maintenance provider perform the work. (Requirement; Compliance.)\n  - Who decides and how: CASA (via its delegate) mandates the action and enforces compliance; operators must follow the Air Cruisers service documents specified by the AD. (First paragraph and Requirement.)\n  - Behaviour required: inspect identification (serial number), and repack the slide/raft according to the named service bulletin and folding procedure revisions within the set timeframes. Uninstalled units must be repacked before installation. (Applicability; Requirement; Compliance.)\n  - Implementation risk: compliance depends on correct identification of affected serial numbers and accurate application of the specified folding procedures. The AD cross‑references FAA AD 2004-03-01 and several manufacturer documents, so operators must obtain and follow those documents. (Applicability; Requirement; Note.)\n  - Compliance burden: the action is a maintenance task (repacking) rather than a design change. The AD reduces rework where units were already repacked under Revision F by recognising that as compliant, which lowers redundant cost for some operators. (Requirement; Note.)\n  - Market effects: the requirement directs business to maintenance providers and to the manufacturer’s procedures but does not change ownership, market structure, or competition rules. It may create short-term demand for maintenance capacity and for authorised parts/procedures. (Requirement; Compliance.)\n\n**Concrete mechanism of risk reduction and any limits\n\n- Mechanism: repacking per the specified service bulletin and folding procedures is intended to prevent separation of the lower aspirator and ensure reliable inflation on deployment. (Background; Requirement.)\n- Limits: the AD relies on procedural fixes (repacking) rather than redesign; if the root cause required hardware modification, this AD would not address that unless further action is mandated. Operators must also ensure ongoing compliance for future installations.
