Think of it like a compulsory recall notice for aircraft, but for safety-critical maintenance.\n\n**What it does:**\n- **Targets:** All Auster/Beagle A.61 Series aeroplanes (small aircraft) built before January 1947.\n- **Requires:** A visual inspection of the tailplane bracing wire strap fittings — specifically looking for cracks near the bolts that hold them in place. (The tailplane is the small horizontal wing at the back of the aircraft that helps keep the plane stable.)\n- **When:** Before the first flight of each day.\n\n**Who can do it:** The pilot in command (the person flying the aircraft) can perform, endorse, and certify this inspection themselves. They don't need to hire a licensed aircraft mechanic for this particular check.\n\n**Why it matters:** Cracks have been found in these fittings, which could lead to structural failure of the tailplane. This amendment makes compliance easier by allowing pilots to do the quick visual check themselves, rather than grounding the aircraft until a mechanic is available.\n\n**Effective date:** 27 April 1995."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"This amendment changes who may perform and certify the required inspection: it explicitly permits the pilot in command to perform, endorse and certify the visual inspection on the maintenance release.

(Applicability)\n- Requires a visual inspection of the tailplane bracing wire strap fittings for cracks near the retaining bolts. (Requirement)\n- Requires that inspection be done before the first flight of the day. (Compliance)\n- Permits the pilot in command to perform, endorse and certify this inspection on the maintenance release. (Note; \"This amendment allows the pilot in command to perform the inspection.\")\n\nWho this affects and why it matters:\n\n- Aircraft owners/operators and pilots of the specified aeroplanes must ensure the specified visual check is completed daily before the first flight. (Applicability; Requirement; Compliance)\n- The pilot in command is explicitly permitted to carry out and certify the inspection, which changes who may lawfully perform and sign off the check. (Note; \"This amendment allows...\")\n\nHow it works in practice and the operational trade-offs (source-grounded):\n\n- Task required: a visual inspection for cracks specifically at the tailplane bracing wire strap fittings near the retaining bolts. The instrument does not describe a testing method beyond visual inspection or set out corrective steps if a crack is found. (Requirement)\n- Timing: the inspection must be completed before the first flight of the day, so it is a daily pre-flight action for affected aircraft. (Compliance)\n- Delegation and certification: the amendment permits the pilot in command to perform and sign the maintenance release for this particular inspection, rather than requiring a separate maintenance-personnel endorsement. This shifts the decision and a portion of compliance effort onto the pilot in command. (Note; \"This amendment allows the pilot in command to perform the inspection.\")\n- Risk trigger and purpose-claim: the instrument records that cracks have been detected in the bracing wire attachment fittings, which is the stated basis for the inspection requirement. (Background)\n\nCosts, incentives and compliance burden (grounded in the text):\n\n- Who pays: operators/pilots of the affected aircraft bear the time cost of performing the daily visual inspection. (Applicability; Compliance)\n- Incentives: permitting the pilot in command to perform and certify the inspection reduces dependence on separate maintenance personnel for this task; the text does not describe any financial compensation or technical support. (Note)\n- Compliance burden: the directive requires a recurring daily action (before first flight) and a certification on the maintenance release; the document does not prescribe detailed inspection criteria or remedial actions, which may require operators to adopt their own follow-up procedures if cracks are observed. (Requirement; Compliance)\n\nImplementation risk and discretion:\n\n- The AD specifies a visual inspection but does not define pass/fail criteria or mandatory corrective measures in the event cracks are found; that leaves discretion to the person performing the inspection and the operator to determine the next steps within whatever broader regulatory or operational frameworks apply. (Requirement)\n- The amendment expressly changes who may perform and certify the inspection (pilot in command), altering the locus of responsibility for this check. (Note; \"This amendment allows the pilot in command to perform the inspection.\")\n\nEffective date and formality:\n\n- The AD is effective from 27 April 1995. (This AD is effective from 27 April 1995.)\n\nSource citations: key text taken from the AD sections titled Applicability, Requirement, Note, Compliance and Background."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing","history":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing/history","analysis":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing/analysis","conflicts":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing/conflicts","importantCases":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing/important-cases","documents":"/api/acts/ad-aus-6-amdt-1-tailplane-bracing/documents"}}
