The inspection and any necessary replacement must follow the manufacturer's instructions in PZL Mandatory Service Bulletin E/02.184/2003.\n\n**Which aircraft and parts are affected**\n\n- Applies to all PZL M18, M18A and M18B aeroplanes that have safety harnesses with part numbers D74.183.2L, D74.183.00.2P or D74.186.00.1, where those harnesses were manufactured after 1 January 1994. (See the \"Applicability\" section.)\n\n**What you must do and when**\n\n- Inspect the listed safety harnesses and replace them if required, following PZL Mandatory Service Bulletin E/02.184/2003 (see the \"Requirement\" section).\n- The required actions must be completed before 24 July 2003. The AD became effective on 10 July 2003 (see the \"Compliance\" section).\n\n**Why this action was ordered**\n\n- The manufacturer reported that some belt length adjusters were incorrectly attached to the harnesses. Tests showed some incorrectly manufactured belts fail at less than the design strength. The AD cites this unsafe condition as the reason for the mandated inspections and replacements (see the \"Background\" section). The AD also notes a corresponding Polish airworthiness directive (SP-0010-2003-D).\n\n**Who pays, who decides, and what changes**\n\n- Who pays: aircraft owners/operators pay for the inspection, any replacements, and associated labour and downtime. Replacement parts, if required, are a direct cost to the operator unless covered by another arrangement (warranty, manufacturer support, etc.).\n- Who decides/authorises: the AD is issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998; the technical steps are specified by the manufacturer in the referenced Mandatory Service Bulletin.\n- Behavioural change required: operators must schedule and carry out the inspection/replacement before the compliance date and retain the work records as required by normal maintenance and regulatory practice.\n\n**Practical effects, trade-offs and implementation issues**\n\n- Safety vs. cost/time: the directive imposes a short-term cost and aircraft downtime in exchange for reducing the risk of harness failure in flight. The magnitude of cost depends on the number of affected harnesses and whether replacements are necessary.\n- Delegation of technical detail: the AD requires action in accordance with the manufacturer's Mandatory Service Bulletin; CASA delegates the technical inspection/replacement procedures to that bulletin, so operators must follow the manufacturer's exact procedures to be compliant.\n- Supply and logistics risk: if replacement harnesses are scarce, operators may face delays beyond inspection time. Operators should confirm parts availability when planning compliance.\n- Scope is narrow and targeted: only specific part numbers and harnesses manufactured after a set date are affected, limiting impact to aircraft with those parts.\n\n**Source sections cited**: Applicability, Requirement, Compliance, Background, and Note (Polish AD reference)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pzl-6-inspection-of-safety-belts","history":"/api/acts/ad-pzl-6-inspection-of-safety-belts/history","analysis":"/api/acts/ad-pzl-6-inspection-of-safety-belts/analysis","conflicts":"/api/acts/ad-pzl-6-inspection-of-safety-belts/conflicts","importantCases":"/api/acts/ad-pzl-6-inspection-of-safety-belts/important-cases","documents":"/api/acts/ad-pzl-6-inspection-of-safety-belts/documents"}}
