COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
De Havilland Piston Engines
AD/DHE/22 Minimum Modification Standard at Major Reconditioning
6/72
Applicability: Gipsy Queen 11.
Document: R.Royce Gipsy TNS G No. 15 dated 18 February 1970 and Appendix 3 dated 27 June 1963.
Compliance: Before installation following next reconditioning completed after 30 June 1972.
Overview
The Civil Aviation Regulations 1998 were enacted by the Australian Government to regulate civil aviation within the country. A part of these regulations is the Airworthiness Directives, which includes AD/DHE/22 concerning the minimum modification standard for De Havilland Gipsy Queen 11 piston engines at major reconditioning. This legislative instrument was introduced to ensure the safety and reliability of civil aircraft by specifying technical standards and requirements for the maintenance and modification of aircraft components. The policy objective is to mitigate risks associated with the operation of aircraft by enforcing strict airworthiness directives. The compliance requirement for these directives must be met by aircraft operators before installation following the next reconditioning of the engines, specifically those completed after 30 June 1972, ensuring adherence to the standards set forth in the referenced documents.
Scope and Application
The Civil Aviation Regulations 1998, as amended, apply to all aircraft operators and maintenance organisations within the Commonwealth of Australia, with specific focus on the airworthiness directives outlined in Part 39. Specifically, the AD/DHE/22 regulation pertains to the minimum modification standard at major reconditioning for Gipsy Queen 11 engines, a category that includes but is not limited to De Havilland piston engines. This regulation mandates compliance with the document titled "R.Royce Gipsy TNS G No. 15 dated 18 February 1970 and Appendix 3 dated 27 June 1963," ensuring that any reconditioning of the specified engines is completed in accordance with the outlined standards before any subsequent installation. The regulation applies to engines reconditioned after 30 June 1972, thereby imposing a temporal boundary on its scope. While the primary focus is on the airworthiness and maintenance of specified aircraft engines, it does not explicitly state exclusions or exemptions, thereby implying a broad application unless otherwise specified in subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998 (Cth), under Part 39, specifically Section 106, mandates that the Civil Aviation Safety Authority (CASA) issue airworthiness directives for certain aircraft components, including the Gipsy Queen 11 piston engine manufactured by De Havilland. This particular directive, AD/DHE/22, sets out the minimum modification standards required when these engines undergo major reconditioning (Section 106). The directive references the document R.Royce Gipsy TNS G No. 15 dated 18 February 1970 and Appendix 3 dated 27 June 1963, which provides the technical specifications and procedures necessary for compliance.
Compliance with this directive is mandatory for all Gipsy Queen 11 engines that undergo a major reconditioning after 30 June 1972. The requirements include implementing specific modifications to ensure the engine meets the airworthiness standards set by CASA. These modifications must be completed before the engine is reinstalled in an aircraft, ensuring that the engine is safe and reliable for operation.
Entities and individuals governed by this legislation have several obligations. They must ensure that any major reconditioning of a Gipsy Queen 11 engine is performed in accordance with the specifications provided in the referenced documents. This includes conducting necessary inspections, making required modifications, and maintaining detailed records of the work performed. It is crucial that all modifications are carried out by appropriately certified personnel to ensure adherence to CASA standards.
Failure to comply with the provisions of AD/DHE/22 can result in serious consequences. CASA may take enforcement action against entities or individuals who do not adhere to the airworthiness directives. Potential penalties include fines, suspension or revocation of operating certificates, and other administrative actions. The specific penalties depend on the nature and severity of the non-compliance, with the potential for significant financial and operational repercussions for those found in breach of the regulations.
