It requires inspection of specified landing-gear parts on certain Eurocopter (Aerospatiale) Gazelle helicopters. (Header: \"COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105... SCHEDULE OF AIRWORTHINESS DIRECTIVES\"; \"AD/GAZELLE/14 Landing Gear - Inspection 7/83\")\n\nWho it affects\n\n- Operators and owners of Eurocopter SA341 and SA342 helicopters that are fitted with landing gear part numbers 341A41.5200 or 341A41.5300 (all dash‑numbers). (Applicability)\n\nRequired action and timing\n\n- Those affected must carry out the inspection detailed in Aerospatiale Gazelle Service Bulletin No. 32.02. The inspection must be done within 30 days after 6 June 1983, unless it has already been accomplished. (Document; Compliance)\n\nWhy it matters (stated purpose)\n\n- The stated reason is that the manufacturer reported a failure at the junction between the rear cross tube and the rear arch tube. The directive therefore mandates inspection to detect that problem. (Background)\n\nPractical consequences, incentives and costs\n\n- Who pays: Operators/owners of the affected helicopters bear the direct cost of performing the inspection (labour, facility time, and any follow‑on repairs if defects are found). (Applicability; Compliance)\n- Who decides and enforces: The Civil Aviation Safety Authority issued the directive under the cited regulations, and compliance is required by the directive. (Header)\n- Behaviour change: Operators must schedule and perform the inspection within the specified 30‑day window or demonstrate it was already completed. If the inspection identifies a defect at the rear cross tube/rear arch tube junction, additional maintenance or part replacement will be required, which increases downtime and cost. (Compliance; Background)\n\nTrade-offs, implementation risks and compliance burden\n\n- Compliance burden: The directive sets a single required action (an inspection) and a single deadline (30 days after 6 June 1983). The technical nature of the inspection means operators will need qualified maintenance personnel and access to the Aerospatiale Gazelle Service Bulletin No. 32.02 for the inspection procedure. (Compliance; Document)\n- Implementation risk: Effective implementation depends on access to the referenced service bulletin for step‑by‑step procedures and on correct identification of the specified landing‑gear part numbers. If the inspection is not done correctly or on time, the reported junction failure could remain undetected. (Document; Background)\n- Discretion: The directive provides a mandatory timetable and references the service bulletin; the text does not offer alternate compliance methods or exemptions within the instrument itself. (Compliance; Document)\n\nEffects on private choice and market considerations\n\n- The directive narrows choices for affected operators by imposing a mandatory inspection and timetable for specific parts. It may increase short‑term maintenance demand for providers with the skills to carry out the inspection and any necessary repairs. The requirement applies only to helicopters with the listed landing gear part numbers, concentrating compliance costs on their owners.

The inspection targets a known weak point where the rear cross tube connects to the rear arch tube.\n\n**Who it affects:** Anyone operating Gazelle helicopters fitted with specific landing gear part numbers (341A41.5200 and 341A41.5300, any dash-number variant).\n\n**Why it matters:** The manufacturer (Aerospatiale, now Airbus Helicopters) reported failures at this junction. Without inspection, the landing gear could fail during landing, risking aircraft damage, injury, or death.
