(See \"Requirement\".)\n- The modification must be carried out in accordance with Fokker Service Bulletin SBF100‑33‑016 Revision 4 dated 1 February 2005, or a later revision that has been approved by EASA (the European Aviation Safety Agency).\n- Aeroplanes that were already modified before the effective date in accordance with earlier versions of that Service Bulletin do not need any further action.\n- The work must be completed by 31 December 2007. The directive became effective on 31 August 2006. (See \"Compliance\" and \"Effective date\".)\n\n**Who this affects**\n\n- Owners and operators of Fokker F100 (F28 Mk 100) aircraft whose serial numbers appear in the applicable Service Bulletin. (See \"Applicability\".)\n- Maintenance organisations and licensed engineers who must perform the modification to the specification in the Service Bulletin.\n- The Civil Aviation Safety Authority (CASA) enforces compliance; the directive was issued by a CASA delegate. The Service Bulletin and any EASA approvals set the technical standard for the work.\n\n**Why it matters (official rationale and mechanical effect)**\n\n- The stated reason is to ensure the lighting on those aeroplanes meets the certification requirements in the cited US and European airworthiness regulations (FAR/JAR/JAR‑like provisions for anti‑collision and strobe lights). The Background section cites a Netherlands AD (CAA‑NL AD NL‑2006‑007) and says this Directive supersedes an earlier RLD AD.\n\n**Who pays and who decides**\n\n- Aircraft owners/operators pay for parts, labour and aircraft downtime to carry out the modification. The Service Bulletin specifies the technical steps; EASA (and by reference the CAA‑NL) provides approval of revisions; CASA enforces the compliance deadline.\n\n**Practical trade‑offs, costs and implementation issues**\n\n- Direct costs: the parts and labour to modify the anti‑collision and strobe lights and any associated inspections or wiring work called for in the Service Bulletin.\n- Operational costs: scheduling the work (aircraft out of service), potential disruption to flight operations, and possible short‑term replacement capacity costs.\n- Compliance burden: the work must be performed to the Service Bulletin standard and by appropriately approved maintenance organisations; operators must track serial‑number applicability and the compliance deadline.\n- Flexibility: the AD accepts later EASA‑approved revisions of the Service Bulletin, which allows operators to rely on an updated technical standard if EASA approves it.\n- Risk and practicability: availability of approved parts and qualified maintenance slots can affect the ability to meet the deadline; no specific remediation or subsidy is provided in the directive.\n\n**Effects on private choice and the market**\n\n- The directive restricts private choice in the narrow sense that affected operators must carry out the specified modification by the deadline rather than choosing alternative mitigations.\n- It imposes a compliance cost concentrated on owners/operators of the affected serial‑number aircraft; the safety benefit (if achieved) is a diffuse public good (improved compliance with airworthiness standards).\n\n**Scope and legal mechanics**\n\n- The AD is narrowly framed: it applies only to the serial numbers listed in the referenced Service Bulletin and only to the lighting items specified. It explicitly exempts aeroplanes already modified under earlier versions of the same Service Bulletin.\n- The AD cross‑references foreign certification requirements and a Netherlands (CAA‑NL) AD; the Service Bulletin is the technical means of compliance.
