The AD itself does not state the previous scope or how it was altered, but the amendment label combined with the explicit applicability suggests the scope was adjusted from an earlier version: the authority, affected serial numbers, or compliance instructions were likely changed and are now fixed as shown (see \"Amdt 1\", \"Applicability\" and \"Compliance\" lines)."},"complexity_factors":["Narrow technical scope limited to a particular modification (elevator/aileron unit limits).","Precise applicability by serial number with explicit exclusions (requires accurate fleet identification).","Fixed, non-negotiable compliance date (operational scheduling constraint).","Dependence on an external technical document (AMD SB BA F10-0165 R4) for implementation details.","Regulatory provenance (issued under Civil Aviation Regulations/Part 39) implying mandatory compliance but limited explanatory text in the AD itself."],"plain_english_summary":"This AD requires owners/operators of Falcon 10 aircraft (serials 1–140, excluding 124, 126, 127, 129, 130, 133, 136) to modify elevator/aileron Arthur Q unit limits by following AMD SB BA F10-0165 R4 (F10-27-022).

The modification addresses limits on something called the \"Arthur Q Unit\" — a component related to the aircraft's flight controls.\n\n**Who it affects:**\n- Owners and operators of AMD Falcon 10 aircraft\n- Specifically: all serial numbers 1 through 140, **except** serial numbers 124, 126, 127, 129, 130, 133, and 136\n\n**What must be done:**\nThe aircraft must be modified according to the manufacturer's service bulletin **AMD SB BA F10-0165 R4** (also referenced as F10-27-022).\n\n**When:**\nThe modification had to be completed **before 13 July 1979**.\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety requirements. They typically issue when a design flaw, wear pattern, or operational issue is discovered that could affect flight safety. Non-compliance means the aircraft cannot legally fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification","history":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification/history","analysis":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification/analysis","conflicts":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification/conflicts","importantCases":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification/important-cases","documents":"/api/acts/ad-amd-10-10-amdt-1-elevator-aileron-arthur-q-unit-limits-modification/documents"}}
