(AD title)\n- It applies to all models of the Fokker F28 series. (Applicability)\n- The required action is to carry out the inspection following the procedures referenced in Fokker Service Bulletin F28/25-25. (Document)\n- The inspection must be completed within 150 hours time in service after 30 July 1971. (Compliance)\n\nWho it affects and who decides\n\n- Aircraft operators/owners of Fokker F28 series aeroplanes are the parties that must carry out and pay for the inspection and any follow-up work. (Applicability; Compliance)\n- The Civil Aviation Safety Authority (as issuer of the Schedule of Airworthiness Directives under the Civil Aviation Regulations) is the regulator requiring compliance; the AD points operators to the Fokker service bulletin for the technical procedure. (AD title; Document)\n\nWhat behaviour changes and immediate costs\n\n- Operators must schedule and perform the specified inspection within the stated compliance window. (Compliance)\n- Direct costs fall to operators: labour time to perform the inspection, possible downtime for the aircraft while inspected, and any repair or replacement costs if the inspection finds defects. (Applicability; Document; Compliance)\n- The AD itself does not set repair instructions in the text provided; it refers operators to Fokker SB F28/25-25 for the technical procedure and any corrective actions. (Document)\n\nWhat the source states about purpose and what it does not state\n\n- The text of the AD sets out the mandatory inspection requirement and the compliance timeline but does not include an explicit statement of the safety concern or rationale in the excerpt provided. (AD title; Compliance)\n- Because the AD cites a Fokker service bulletin for the technical steps, the detailed inspection method and criteria for corrective action are located in that referenced document, not in the AD text supplied. (Document)\n\nConsequences for private actors and broader effects (based on what the AD specifies)\n\n- Private aircraft operators bear the compliance cost and must allocate maintenance resources within the compliance time. (Applicability; Compliance)\n- The AD imposes an operational constraint (inspection within a defined hours window) that can affect aircraft availability while the work is done. (Compliance)\n- The AD text supplied does not specify impacts on competition, prices, ownership, contracts, or speech. There is no content in the excerpt that changes ownership rules or market entry; its effect is limited to the operational and maintenance obligations for the affected aircraft. (Applicability; Document)\n\nImplementation and compliance notes\n\n- Operators must consult Fokker SB F28/25-25 for the inspection procedure and any corrective actions; the AD alone does not provide procedural detail. (Document)\n- The compliance deadline is expressed as \"within 150 hours time in service after 30 July 1971,\" which places a concrete inspection window in time; the AD requires the action be completed within that window. (Compliance)\n- The AD does not set out enforcement or penalty provisions in the excerpt supplied; enforcement would follow the normal regulatory mechanisms under the Civil Aviation Regulations applicable to airworthiness directives.
