(Requirement)\n- The requirement applies only to aircraft listed by model and serial number that are fitted with Goodyear BTC-39 fuel cells: Models 36 and A36 with S/Nos E-1 to E-476. (Applicability)\n- Those actions must be done within 100 hours time in service after 30 June 1978, and then repeated at intervals not exceeding 12 months. (Compliance)\n\nWhy it matters (stated purpose and practical effect)\n\n- The instrument imposes a recurring mandatory maintenance or inspection action on a defined set of aircraft. The text does not itself state the technical problem or failure mode being addressed; it instead directs operators to follow Beechcraft SI No. 0895. (Requirement)\n\nWho pays and who decides\n\n- Aircraft owners or operators of the affected serial-numbered Beechcraft 36/A36s are responsible for meeting the directive. They bear the direct costs of any inspections, repairs, replacements, labour or downtime required by Beechcraft SI No. 0895. (Applicability; Requirement; Compliance)\n- The Civil Aviation Safety Authority publishes and enforces the airworthiness directive; the exact tasks and methods to be performed are delegated to the Beechcraft service instruction that the directive references. (Requirement)\n\nIncentives, compliance burden and implementation points to watch\n\n- Compliance is periodic and prescriptive: an initial compliance window (100 hours after 30 June 1978) followed by annual repetitions. This creates an ongoing maintenance cost and scheduling obligation for affected operators. (Compliance)\n- The directive relies on an external technical document (Beechcraft SI No. 0895) to specify the required work. The operator must obtain and follow that service instruction; the directive does not contain the technical detail itself. (Requirement)\n- Practical implementation depends on availability of parts, approved replacement fuel cells or repair procedures, and suitably qualified maintenance personnel who can implement the service instruction. These dependencies affect cost and downtime but are not specified in the directive. (Requirement)\n- Maintenance providers and approved repair stations may see increased demand from operators complying with the directive; conversely, an operator facing high compliance costs might choose to limit operations or remove the affected fuel cell installation. The instrument does not mandate a particular business or supply response. (Applicability; Requirement)\n\nTrade-offs, scope and enforcement\n\n- The directive narrows applicability to a specific component type (Goodyear BTC-39 fuel cells) on a defined fleet subset (Models 36/A36, S/Nos E-1 to E-476). This concentrates compliance costs on a limited group of owners while leaving other aircraft unaffected. (Applicability)\n- Enforcement is through an airworthiness directive mechanism: compliance is mandatory for the named aircraft. The text does not describe penalties or enforcement procedures beyond the requirement itself. (Requirement; Compliance)\n\nWhat is not in the text and therefore uncertain\n\n- The directive does not state the technical defect or hazard prompting the action; that information may be contained in Beechcraft SI No. 0895 or other advisory material. (Requirement)\n- The directive does not quantify likely costs, downtime, parts availability, or qualifications required for technicians. These operational impacts must be determined from the service instruction and market conditions. (Requirement)\n\nKey citations\n\n- Applicability: Models 36 and A36 with S/Nos. E-1 to E-476 fitted with Goodyear BTC-39 fuel cells. (Applicability)\n- Required action: “Action in accordance with Beechcraft SI No. 0895.” (Requirement)\n- Timing: Within 100 hours TIS after 30 June 1978 and thereafter at intervals not exceeding twelve months.
