(Requirement)\n\nWho is affected\n\n- Owners/operators of Beechcraft 65-B80 aircraft with serial numbers LD-270 through LD-480, and Beechcraft 70 models with serial numbers LB-1 through LB-35, but only if those aircraft have either Hoskins P/N 30-0187-21 or Grimes P/N 30-0669-1 wing strobe lights installed. (Applicability)\n\nHow it works, mechanically\n\n- The AD does not state the technical steps itself; it mandates compliance with the external Beechcraft SI No. 0800-362. Affected aircraft must have the action in that SI performed within 100 hours’ time in service after 29 October 1976. (Requirement, Compliance)\n\nWho pays, who decides, and what changes\n\n- Owners/operators of the listed aircraft are the parties who must obtain the Beechcraft service instruction and carry out the required work; therefore they bear the direct costs (parts, labour, aircraft downtime). (Requirement, Applicability)\n- The AD (issued and recorded in the Schedule of Airworthiness Directives) is the regulator’s instrument that mandates the work and sets the compliance deadline; the AD itself requires the action “in accordance with” the specified Beechcraft SI, so the exact technical method is decided by that SI. (Requirement)\n- The behaviour change required is a maintenance action on wing strobe lights for the subset of Queen Air aircraft identified; operators must schedule and document that work within the stated timeframe. (Requirement, Compliance)\n\nImplementation, costs and risks\n\n- Compliance depends on obtaining and following Beechcraft SI No. 0800-362; the AD text does not include the technical details, so implementation requires access to and reliance on that external document. (Requirement)\n- Direct costs will typically include parts and labour; indirect costs include aircraft downtime while the work is carried out and administrative record-keeping to show compliance within the 100 hours’ time-in-service deadline. (Compliance)\n- The AD consolidates Queen Air series 65 and 70 aircraft under this directive (Amendment 1), which changes the set of aircraft addressed by this AD compared with the prior text. (Background)\n\nTrade-offs and administrative burden\n\n- The AD targets a defined, limited set of aircraft and specific strobe light part numbers, which narrows the compliance population but concentrates costs on those owners/operators. (Applicability)\n- The AD creates a clear, short compliance window (100 hours’ time in service measured from a historic date), which imposes scheduling and recordkeeping obligations on affected operators. (Compliance)\n\nWhat is not in the AD text\n\n- This AD text does not specify penalties, the technical remedy itself, or alternative means of compliance; those details must be sought in Beechcraft SI No. 0800-362 or other regulatory guidance.

This directive addresses a specific defect or safety concern with those particular light models on these specific aircraft. The amendment simply tidies up the paperwork by combining what were previously separate directives for the 65 and 70 series into one document."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights","history":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights/history","analysis":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights/analysis","conflicts":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights/conflicts","importantCases":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights/important-cases","documents":"/api/acts/ad-beech-65-47-amdt-1-wing-strobe-lights/documents"}}
