Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth Parliament, form the foundational legal framework for civil aviation safety in Australia. This legislation, administered by the Civil Aviation Safety Authority, aims to ensure the safety of aircraft and operations within Australian airspace. Within this regulatory scheme, Part 39 outlines specific directives for maintaining the airworthiness of certain aircraft types, including the DH 104 (Dove) series aeroplanes. The policy objective is to standardise safety protocols and ensure compliance with international aviation standards, thereby protecting public safety and maintaining the integrity of Australia's civil aviation system. One such directive, AD/DH 104/11, pertains to the modification of engine instrument arrangements for Dove series aeroplanes, mandating compliance before 1 September 1971 to address potential safety issues identified with the original design.
Scope and Application
The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically targeting the De Havilland Dove Series aeroplanes. This legislation applies to all models within the Dove series, aiming to ensure that any modifications to the engine instrument arrangement are completed before 1 September 1971. The directive mandates compliance with the specifications outlined in either De Havilland Dove Mod. No. 879, Part B, or the Aeronautical Notice (ANO) 105.1.14.13.5.9. The scope of this AD is comprehensive, encompassing all persons and entities involved in the operation, maintenance, or modification of Dove Series aeroplanes within Australia, thereby ensuring adherence to safety standards set by CASA. The AD does not provide explicit exclusions or exemptions, indicating that all relevant aircraft must comply with the specified modifications to maintain airworthiness.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, specifically address the airworthiness directives for the de Havilland Dove series aeroplanes through AD/DH 104/11. This directive mandates a modification to the engine instrument arrangement. According to section 1, the directive applies to all models of de Havilland Dove aircraft, referencing Document 1 (De Havilland Dove Mod. No. 879, Part B) or Document 2 (ANO 105.1.14.13.5.9). The compliance date set forth in this directive is before 1 September 1971, establishing a clear timeframe for adherence.
Under this legislation, operators of de Havilland Dove aircraft are required to ensure that the specified modifications to the engine instrument arrangement are implemented. This involves a detailed inspection and, where necessary, the retrofitting or replacement of components to meet the safety standards outlined in the referenced documents. The obligations placed on the operators include verifying that all modifications are documented and that the aircraft are maintained in a state of airworthiness as per the regulations.
Failure to comply with the directives stipulated in AD/DH 104/11 can lead to significant legal and operational repercussions. The Civil Aviation Safety Authority (CASA) can impose penalties on operators who do not adhere to the mandated modifications. The severity of the penalties may vary, but they could include fines, suspension of the aircraft's operating certificate, or even criminal charges in cases of gross negligence or willful disregard of safety directives. The exact penalties are not detailed in the text provided, but they are designed to enforce strict compliance with the safety requirements set forth in the regulations.
