(Requirement)\n- The work must be done within 200 hours time-in-service or 12 calendar months after 17 April 2003, whichever comes first, unless it has already been done. (Compliance)\n\n**Who is affected**\n\n- Aircraft owners and operators of the listed Beechcraft 300-series serial numbers: Model 300 (FA‑1 to FA‑230, FF‑1 to FF‑19), Model B300 (FL‑1 to FL‑252), and Model B300C (FM‑1 to FM‑9, FN‑1). (Applicability)\n- Maintenance organisations and mechanics who perform the modification under the service bulletin.\n- Suppliers or the manufacturer who provide the kits/placards and instructions.\n\n**Why it matters (stated purpose and practical effect)**\n\n- Stated purpose: the modification enhances visibility and legibility of exterior door operating instructions so the airstair door or emergency exits can be opened during an emergency. This follows a safety recommendation arising from an accident investigation and the FAA action that addressed the same issue. (Background; Note referring to FAA AD 2003‑02‑03)\n- Practical effect: affected aircraft must carry improved exterior door instruction placards installed according to the manufacturer’s instructions. That changes what operators must do during inspections/maintenance and puts a short-term cost and scheduling requirement on owners/operators.\n\n**Who pays and who decides**\n\n- Owners/operators pay for the kit (if not supplied free) and labour to install it, and must schedule the work within the mandatory compliance window. (Requirement; Compliance)\n- The Civil Aviation Safety Authority (CASA) delegate issued the directive under CAR 1998 subregulation 39.1(1); after issuance, compliance by operators is mandatory. The technical content of the modification is prescribed by Raytheon’s service bulletin and the AD (Requirement).\n\n**Costs, incentives and trade-offs**\n\n- Direct costs: purchase of kit/placard (if applicable) and labour to install it. The magnitude is not stated in the AD; operators must obtain quotes from suppliers/maintenance providers.\n- Incentives: owners/operators are legally required to comply within the time window; failure to comply exposes them to regulatory enforcement and could affect aircraft airworthiness certification.\n- Opportunity cost: time in scheduled maintenance that could have been used for other checks or revenue flights; generally small given the narrow scope of the modification.\n- Concentrated benefit: Raytheon (manufacturer) produced the placards and the mandatory service bulletin, creating a single, specified technical route for compliance. Owners must follow that specified route rather than choose alternative placards or instructions.\n\n**Implementation risk and compliance burden**\n\n- Implementation risk is low: the AD requires installation of an improved instruction placard/kit according to the manufacturer’s Accomplishment Instructions. The modification is non-structural and described as a placard/operating instruction change. (Requirement)\n- Compliance burden is modest but mandatory: scheduling the work within 200 flight hours or 12 months, obtaining the kit/instructions, performing installation, and recording the action in maintenance logs.\n\n**Effects on private choice and market implications**\n\n- Limits discretion: operators must follow Raytheon’s specified kit/instructions rather than alternate methods. (Requirement)\n- Small impact on competition: because the AD specifies the manufacturer’s service bulletin, kit supply and installation work will likely flow to those able to source and fit Raytheon’s approved kit. The AD does not prohibit other solutions, but any alternative would need to meet the AD’s safety requirement and typically would require approval.\n\n**Source’s stated rationale and how it maps to costs and incentives**\n\n- The AD cites an NTSB recommendation and an FAA AD as the reason for improved exterior door instruction placards. (Background; Note referencing FAA AD 2003‑02‑03)\n- Mapping rationale to effects: the safety rationale supports a one-off, inexpensive modification intended to improve emergency egress. The main cost is the small, concentrated expense for owners/operators and the administrative requirement to comply within the set timeframe. The benefit accrues to all occupants of affected aircraft through potentially clearer emergency instructions; the manufacturer benefits from supplying the kits. The AD prescribes a specific technical remedy rather than leaving open multiple approaches, which reduces regulatory uncertainty but concentrates procurement demand.\n\n**Key citations within the instrument**\n\n- Applicability: lists exact affected serial numbers. (Applicability)\n- Required action: fit placards/kit per Raytheon Mandatory Service Bulletin SB 52‑3096 Revision 1. (Requirement)\n- Compliance timeframe: within 200 hours time-in-service or 12 months after 17 April 2003. (Compliance)\n- Background: NTSB recommendation and Raytheon development of improved placards.
