(Applicability; Requirement)\n- The mandated wording must state that those straps **must not** be used as the sole means of securing cargo to TSO C90c / NAS3610 pallets. The straps may still be used as supplemental restraints for those pallets, or to secure cargo to the aircraft floor fittings, provided use follows the aircraft manufacturer’s weight and balance manuals and the strap rated load of 5,000 lbs. (Requirement)\n- The change can be made by inserting a copy of the directive into the AFM and WBM; once the statement is incorporated into general revisions of those manuals, the inserted copy may be removed. (Note 1)\n- Compliance deadline: within 14 days after 1 December 2004. (Compliance)\n\n**Who is affected**\n\n- Aircraft operators, maintenance organisations and flight operations departments responsible for Fokker F28 aircraft on which the specified straps were installed under STC ST01004NY. (Applicability)\n- Organisations that prepare and maintain the AFM and WBM for those aircraft. (Requirement)\n\n**Why it matters (official rationale and practical effect)**\n\n- The directive implements a safety limitation: it removes the permissibility of using the named strap part (1519-MCIDS) as the only restraint for cargo on certain standard pallets. The stated aim (referenced to FAA AD 2004-22-01) is to correct an unsafe condition linked to that installation method. (Requirement; Note 2)\n\n**Practical consequences, costs and incentives**\n\n- Who pays: operators bear the direct costs of updating manuals, training crew or ground staff on the revised loading procedure, and any hardware changes needed to provide additional or alternative cargo restraint. (Requirement)\n- Behaviour change required: ground crews and loading agents must stop relying on these straps alone for securing cargo to TSO C90c / NAS3610 pallets; they must either add supplemental restraints or use aircraft floor fittings or compliant pallet restraint systems in accordance with the WBM/AFM and the 5,000 lb strap rating. (Requirement)\n- Implementation burden: primarily administrative (manual revisions, distribution) and operational (revising loading practices, possible procurement or reconfiguration of restraint equipment). The AD permits a temporary insertion of the directive text into manuals to meet the requirement quickly. (Requirement; Note 1)\n- Compliance and discretion: CASA issued the directive under its regulation-making power for airworthiness; enforcement and interpretation will rest with CASA delegates and inspectors and with the aircraft operator’s continuing airworthiness obligations. (preamble; Requirement)\n\n**Trade-offs and risks**\n\n- Opportunity cost: operators may need to invest in additional restraint equipment or loading steps that increase turnaround time or cost per flight. Those are private costs borne by affected operators. (Requirement)\n- Substitution effects: operators may shift to other restraint systems, change pallet types, or rely more on aircraft floor fittings — these operational choices affect supply chains for restraint hardware and ground-handling procedures. (Requirement)\n- Implementation risk: misreading the permitted uses (for example, continuing to use the strap as the sole restraint in error) creates continued safety exposure; conversely, overly cautious responses (removing all such straps immediately) could impose unnecessary expense. (Requirement; Note 1)\n\n**Reference points**\n\n- The AD cross‑references FAA AD 2004-22-01, indicating coordination with FAA findings or requirements. (Note 2)\n\nOverall, mechanically this instrument is an operational restriction implemented by mandating specific manual revisions and a short compliance window. It changes the permitted use of a particular installed restraint part (1519-MCIDS) on affected F28 aircraft and leaves enforcement and interpretation to CASA and the operator’s continuing airworthiness processes.
