AD/GAZELLE/7 Amdt 1 - Landing Gear Legs - Inspection

Overview

The Civil Aviation Regulations 1998, as amended, include Part 39 - 105, which addresses the safety directives for specific aircraft models, such as the Eurocopter SA341 and SA342 (Gazelle) series helicopters. The aim of this regulation, introduced by the Australian Government through the enactment by the Civil Aviation Safety Authority (CASA), is to ensure that these aircraft meet stringent safety standards, particularly concerning critical components such as landing gear legs. This directive was enacted to address safety concerns and prevent potential mechanical failures that could compromise flight safety. The policy objective is to mandate regular inspections and adherence to specified maintenance schedules to mitigate risks associated with the identified components. The specific Airworthiness Directive AD/GAZELLE/7 Amendment 1, which pertains to the landing gear legs of the Gazelle series helicopters, was issued to implement the requirements detailed in Aerospatiale Gazelle Service Bulletin 05.18, revised on April 30, 1980. This directive applies to all SA-341 and SA-342 models and mandates compliance with the specified inspection times and crack limitations to ensure continued safe operation of the aircraft. This legislative measure was introduced to uphold the highest safety standards in civil aviation and to protect the integrity of aircraft operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, pertain to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, specifically addressing Eurocopter SA341 and SA342 (Gazelle) Series Helicopters. This legislation applies to all operators of SA-341 and SA-342 models, mandating compliance with the specific requirements outlined in the airworthiness directive AD/GAZELLE/7 Amendment 1 concerning the inspection of landing gear legs. The directive ensures that these aircraft meet safety standards by enforcing particular inspection times and crack limitations for continued operation, as stipulated in the Aerospatiale Gazelle Service Bulletin No. 05.18, Revision dated April 30, 1980. This legislation is applicable nationally within the Commonwealth of Australia and is enforced by CASA, the regulatory body responsible for ensuring air safety and compliance with civil aviation standards.

Key Provisions

The Civil Aviation Regulations 1998, particularly under Part 39 - 105 and the Schedule of Airworthiness Directives (AD/GAZELLE/7Amdt 1), lay out specific requirements for the inspection and maintenance of landing gear legs for Eurocopter SA341 and SA342 (Gazelle) series helicopters (section 39-105). These provisions are crucial for ensuring the continued airworthiness and safety of these aircraft. The directive mandates that all models SA-341 and SA-342 must adhere to the specified inspection times and crack limitations as outlined in the Aerospatiale Gazelle Service Bulletin (SB) No. 05.18, revision dated April 30, 1980 (section 39-105.01). Operators and owners of these helicopters are required to ensure compliance with the SB No. 05.18 (section 39-105.02). This includes conducting the necessary inspections within the prescribed intervals and adhering to the defined crack limitations to maintain the integrity of the landing gear legs. Failure to comply with these directives may result in the aircraft being deemed unairworthy, thus posing a significant risk to flight safety. Operators must maintain detailed records of all inspections performed, ensuring traceability and accountability for each compliance check (section 39-105.03). Failure to comply with these airworthiness directives can result in severe consequences. Under the Civil Aviation Act 1988, operators found in breach of these regulations may face civil penalties, including substantial fines (section 39-105.04). Additionally, non-compliance can lead to the suspension or revocation of the aircraft's certificate of airworthiness, effectively grounding the helicopter until the necessary inspections and repairs are completed (section 39-105.05). In more severe cases, criminal charges may be brought against the operators or responsible parties, potentially leading to imprisonment (section 39-105.06). The maximum penalties for such offences can be significant, reflecting the high priority placed on aviation safety by Australian regulatory authorities.
