AD/DAUPHIN/38 - Front Passenger Door Jettison Mechanism

Overview

The Civil Aviation Regulations 1998, amended in 2006, address specific safety concerns in the aviation industry, particularly for Eurocopter SA 360 and SA 365 (Dauphin) series helicopters. The legislation was enacted to mitigate risks associated with the door jettison mechanism, a critical safety feature in these aircraft models. This Act was introduced by the Australian Government to ensure the safe operation of these helicopters, specifically targeting a known issue with the front passenger door jettison mechanism. The policy objective behind the enactment is to mandate adherence to Eurocopter's corrective measures, ensuring compliance with safety standards and preventing potential accidents. The Civil Aviation Safety Authority's directive, outlined in the Civil Aviation Regulations, requires specific actions to be taken on certain Dauphin series helicopters to rectify the identified safety hazard. The regulations apply to particular models and serial numbers, excluding those that have already been modified according to a specified amendment. Compliance with the requirement, as detailed in the Eurocopter Mandatory SA 365 SB No.01.38, is critical to maintaining airworthiness and ensuring the safety of passengers and crew. This legislative measure underscores the importance of continuous safety assessments and corrective actions in the aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which includes detailed regulations for ensuring the safety of civil aircraft. This particular directive, AD/DAUPHIN/38, focuses on the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters and mandates actions concerning the front passenger door jettison mechanism. The directive applies to specific model SA 365 N helicopters, including versions N, N1, and N2 that have not undergone a particular modification identified as AMS 365A07-56B15, and specifically targets those with serial numbers 6008, 6033, 6083, 6084, 6085, 6093, and higher than 6120, with certain exceptions noted for serial numbers 6282 through 6299 and those delivered after 25 October 1993. The requirement for compliance is laid out in Eurocopter Mandatory SA 365 SB No.01.38, and adherence to the specified actions in the Requirement Document is mandated. The scope of this directive is national, extending across the Commonwealth of Australia, ensuring that all relevant helicopters meet the stipulated safety standards.

Key Provisions

The key provisions of this legislative instrument (AD/DAUPHIN/38) are found within the Civil Aviation Regulations 1998, specifically in Part 39 - 105, which pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. This directive addresses the front passenger door jettison mechanism for Eurocopter SA 360 and SA 365 (Dauphin) series helicopters. The directive applies to specific models and serial numbers of the SA 365 N helicopter series, excluding those that have been modified or have specific serial numbers not listed (Section 5/94). The requirement outlined in the directive is that affected helicopters must be modified in accordance with Eurocopter Mandatory SA 365 Service Bulletin No. 01.38. This requirement is referenced in the directive to ensure the safety of the aircraft by addressing a door jettison mechanism anomaly identified during production (Section 5/94). Compliance with this directive is to be achieved as specified in the Requirement Document, which will detail the specific modifications to be made. The obligations imposed by this Act on the operators or owners of the affected helicopters include ensuring that the front passenger door jettison mechanism is modified as per the requirements set out in Eurocopter Mandatory SA 365 SB No. 01.38. This involves following the detailed instructions provided in the Requirement Document, which specifies the technical modifications to be implemented. Operators must ensure that the modifications are carried out by qualified personnel and that the aircraft is inspected to confirm compliance with the directive. The directive also references DGAC AD 94-052-035(B), indicating that compliance with this additional regulatory requirement is also necessary. Failure to comply with the provisions of this directive could result in serious safety risks, and there are potential civil and criminal consequences for non-compliance. While the specific penalties are not detailed in the directive, non-compliance with CASA airworthiness directives can result in significant fines, suspension or revocation of the aircraft’s certificate of airworthiness, and other regulatory actions. Civil Aviation Safety Regulations 1998 provide for enforcement actions that could include hefty fines and potential imprisonment for individuals found in breach of the regulations. The precise penalties would depend on the specific breach and could be pursued through the courts. It is essential for operators to adhere to the directive to avoid these potential consequences.
