The affected hook lacks a tongue locking system. (Applicability; Requirement.)\n\n- The required actions are those set out in Eurocopter Alert Service Bulletin (ASB) No. 01.00.70.2 (paragraph 2.A) and ASB No. 01.00.70 (paragraph 2.B). The amendment converts a previously referenced foreign airworthiness directive into those Eurocopter service bulletins without changing the technical requirement. (Requirement; Background.)\n\n**Who it affects:**\n\n- Owners, operators and maintenance organisations of Model AS 332 C, C1, L and L1 helicopters that have Breeze hoists fitted with hook assembly part number BL-7520-01 and hook part number BL-7520. (Applicability.)\n\n**When the work must be done:**\n\n- The operational check must be performed before each hoisting operation. (Compliance: before each hoisting operation.)\n- The ASB instructions also had a one-off compliance window described as \"within 2 months after 10 November 2004\"; the amendment leaves those timing requirements unchanged. (Compliance.)\n\n**Why it matters (stated cause and technical risk):**\n\n- The directive was prompted by an incident in which a strap was incorrectly positioned on the hoist hook, distorting the hook tongue and allowing a stretcher to be released during a hoisting operation. The check and the ban on straps are intended to prevent re-occurrence by ensuring correct hook use. (Background.)\n\n**Who pays and who decides:**\n\n- The costs fall on helicopter operators and their maintenance providers: they must perform the operational procedure, enforce the strap prohibition, and record compliance as required by their safety processes. The Civil Aviation Safety Authority (CASA) enforces the directive; the specific actions to take are set out in the Eurocopter ASBs cited. (Requirement; Compliance.)\n\n**Practical effects and trade-offs to note (tested against incentives, costs and implementation risks):**\n\n- Compliance burden: the recurring requirement to check the hook before every hoist increases pre-operation workload and requires crew training and procedure updates (operator cost and time). (Compliance; Requirement.)\n\n- Concentrated benefit, diffuse cost: the immediate safety benefit accrues to the people being hoisted and rescue teams (concentrated beneficiaries), while the cost (time, possible retraining) is borne by operators and maintenance organisations (more diffuse across industry). (Background; Requirement.)\n\n- Limited scope of technical change: the amendment does not require replacing hooks or retrofitting a locking tongue; it converts the compliance reference into Eurocopter ASBs and leaves technical content unchanged. That keeps capital cost low but continues to rely on operational controls (Background; Requirement). \n\n- Substitution and market effects: operators who regularly conduct hoisting may choose higher-specification hooks or different hoist systems that include a tongue locking mechanism to reduce repetitive inspection burden; this is a private investment choice not mandated here. (Applicability; Background.)\n\n- Compliance timing and clarity risk: the AD preserves an existing compliance timeline (including a one-off window anchored to 10 November 2004) and cross-references two ASBs. That creates some administrative complexity for operators who must reconcile the AD wording with the ASB instructions and with the historical compliance dates. (Compliance; Requirement.)\n\n- Enforcement and dependence on manufacturer material: CASA enforces the directive but the specific procedures are set in the Eurocopter ASBs. Operators therefore rely on the manufacturer's service bulletin for the exact steps to satisfy the AD. (Requirement.)\n\n**Net practical summary:**\n\nThis is a narrowly targeted airworthiness directive that mandates an operational check and forbids use of straps on a specified Breeze hoist hook on certain Super Puma helicopters because of a reported strap-mispositioning failure. It imposes recurring inspection and training costs on operators, leaves technical hardware unchanged, and points operators to Eurocopter service bulletins for the exact procedures to follow.
