The directive instructs owners/operators to carry out the modification according to a specific service document (AMD SB BA F10-0163 R2 / F10-52-007). (Document; Applicability)\n\nWho is affected\n\n- The rule applies to Falcon 10 aeroplanes with serial numbers 1 through 122, except serial numbers 118 and 121 are excluded. (Applicability)\n\nWhen it must be done\n\n- The required modification must be completed before 31 July 1979. (Compliance)\n\nWhat the directive says it aims to do\n\n- The text of the directive states the action: a modification to the passenger door lock system. That is the stated technical requirement. (Title; Document)\n\nWho pays and who decides\n\n- Aircraft owners or operators are the parties that must arrange and pay for the work, because the directive places the duty to comply on those aircraft within the stated applicability. (Applicability; Compliance)\n- CASA is the regulator issuing the airworthiness directive; the directive points to the service bulletin as the technical instruction for how the work should be done. (Civil Aviation Safety Authority header; Document)\n\nPractical mechanics and effects on behaviour\n\n- Operators must obtain or follow the referenced service bulletin and have the modification performed on each affected aeroplane. This will typically mean scheduling maintenance time, providing access to the aeroplane, and paying for parts and labour. (Document; Compliance)\n- Until the modification is completed an operator may need to restrict operations for compliance or safety reasons; the directive sets a hard deadline. (Compliance)\n- Independent maintenance organisations can perform the work to the extent they follow the service bulletin instructions; that creates demand for maintenance capacity and parts. (Document)\n\nCosts, incentives and trade-offs\n\n- Direct costs: parts, labour, and aircraft downtime are borne by each owner/operator for each affected aeroplane. (Applicability; Document)\n- Timing incentive: the compliance deadline concentrates demand for parts and maintenance labour before the date, which may raise short-term costs or require scheduling changes. (Compliance)\n- Opportunity cost: time spent completing this modification displaces other maintenance or commercial flying time. (Compliance)\n\nImplementation risk and compliance burden\n\n- The directive relies on an external service bulletin for the technical steps. If that bulletin is not available, is unclear, or if parts are scarce, implementation may be delayed or require technical interpretation by maintenance providers. (Document)\n- The directive does not include the service bulletin text in-line; maintenance organisations must obtain and correctly apply that external document. (Document)\n- Enforcement specifics (inspection, penalties) are not set out here; the directive itself prescribes the action and deadline. (Directive text)\n\nEffects on private choice and market actors\n\n- Owners/operators lose discretion to choose whether to make the modification for the affected aircraft: compliance is mandatory within the stated timeframe. (Applicability; Compliance)\n- The rule creates a predictable short-term market for the parts and labour specified by the service bulletin; independent maintenance providers can capture that business if they are certified and available. (Document)\n\nConcentrated benefits and costs\n\n- The set of affected parties is narrow and well-defined (Falcon 10 aircraft with specific serial numbers), so costs are concentrated on those owners/operators. (Applicability)\n- Any safety or operational benefit from the modification is stated implicitly by the required action (a door lock modification), but the directive text itself does not quantify benefits; it only prescribes the modification. (Title; Document)\n\nNet practical summary\n\n- Mechanically, the directive is straightforward: identified Falcon 10 aircraft must be modified to conform with the referenced service bulletin before the stated deadline. The primary, immediate burdens are the cost, scheduling, and correct execution of that modification by owners/operators and their maintenance providers.

The modification must follow the technical instructions in **AMD Service Bulletin BA F10-0163 R2** (also referenced as F10-52-007).\n\n**Who it affects:** All Falcon 10 aeroplanes with serial numbers 1 through 122, **except** serial numbers 118 and 121.\n\n**The deadline:** The modification had to be completed before **31 July 1979**.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions. They typically issue when a design flaw, manufacturing defect, or operational issue is discovered that could affect flight safety. In this case, the passenger door lock system apparently had a problem that required correction to ensure the door would remain properly secured during flight. Failure to comply would make the aircraft unairworthy — meaning it cannot legally fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification","history":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification/history","analysis":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification/analysis","conflicts":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification/conflicts","importantCases":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification/important-cases","documents":"/api/acts/ad-amd-10-7-passenger-door-lock-system-modification/documents"}}
