(See: \"Emergency Escape Hatches - Inspection\"; \"Applicability: All models.\")\n- The directive refers operators to a specific inspection procedure: Hawker Siddeley TNS Heron (114) No. F.16, Issue 1. (See: \"Document: Hawker Siddeley TNS Heron (114) No. F.16, Issue 1.\")\n- Operators must carry out the inspection within 100 hours time in service after 30 June 1971. (See: \"Compliance: Within 100 hours time in service after 30 June 1971.\")\n\n### Who this affects\n\n- Owners and operators of any DH114 (Heron) aircraft, because the directive's applicability is stated as \"All models.\" They are responsible for arranging and paying for the inspection and any follow-up maintenance.\n\n### How it works mechanically\n\n- The regulator (Civil Aviation Safety Authority, under the Schedule of Airworthiness Directives) issues the requirement. The inspection procedure itself is in the referenced Hawker Siddeley document; this directive makes compliance with that procedure mandatory within the stated time window.\n- Compliance is time-based: the inspection must be done within 100 flight hours of service after the cutoff date of 30 June 1971. This sets a firm deadline measured in aircraft time-in-service rather than calendar days. (See: \"Compliance...\")\n\n### Why it matters (stated purpose and practical effects)\n\n- The directive's practical purpose is to ensure that emergency escape hatches meet airworthiness expectations by forcing an inspection according to the manufacturer's procedure (referenced document). The directive does not itself include the inspection steps; it makes the referenced procedure mandatory. (See: \"Document:...\" and \"Compliance:...\")\n\n### Costs, incentives and trade-offs (mechanical, not moral)\n\n- Who pays: aircraft owners/operators pay for the inspection, any repairs found, and any operational downtime while work is done. (Applicability: all models implies all owners/operators.)\n- Incentives: operators have an incentive to schedule the work within the 100-hour window to remain compliant and avoid enforcement action. If the inspection reveals defects, operators incur additional repair costs; if it reveals nothing, the cost is limited to inspection labour and downtime.\n- Compliance burden: the directive ties compliance to a referenced technical manual (Hawker Siddeley TNS Heron (114) No. F.16, Issue 1). Because the AD does not include the technical steps, operators must obtain and follow that document, which concentrates technical burden on qualified maintenance personnel. (See: \"Document:...\")\n- Bureaucratic discretion and implementation risk: the AD prescribes the requirement and references the inspection procedure, but the finer judgment calls (for example, interpretation of an inspection finding or acceptability criteria) will depend on the referenced document and the inspecting engineer’s judgment. The AD itself does not set detailed accept/reject thresholds in the text provided. (See: \"Document:...\" vs the absence of inspection detail in the AD.)\n- Effects on private choice and operations: operators may need to reallocate aircraft to allow inspections, affecting utilization and short-term productivity. The requirement does not alter ownership, market entry, prices, or competition broadly, but it does impose a maintenance cost on all Heron operators.\n\n### Concentrated benefits and diffuse costs\n\n- Benefits (airworthiness of escape hatches) accrue to aircraft users and the flying public; costs are concentrated on Heron operators and maintenance providers who must perform the work. The directive itself does not create subsidies or fees; it creates a compliance cost.\n\n### Implementation notes\n\n- The AD’s compliance window is expressed relative to a historical date (30 June 1971). Operators must interpret the time-in-service measurement and demonstrate compliance in their maintenance records. The technical inspection steps are in the referenced Hawker Siddeley document; operators need access to that document to perform the required actions.
