AD/DHA-3/10 - Hand Brake Installation - Modification

Overview

The Civil Aviation Regulations 1998, as amended by F2006B08968, were enacted to enhance the safety and oversight of civil aviation in Australia. This legislative instrument, introduced to address safety concerns specific to the Drover Series Aeroplanes, particularly the DHA-3 models, mandates modifications to the hand brake installation to ensure compliance with safety standards. The problem it was introduced to address was the need for standardised and rigorous safety protocols to prevent accidents and ensure the airworthiness of these aircraft. The Civil Aviation Safety Authority, under the authority of the Australian Parliament, developed this directive to provide clear guidelines and expectations for maintaining the safety of these aeroplanes. The policy objective is to mitigate risks associated with the operation of Drover Series Aeroplanes by enforcing specific modifications that enhance safety and reliability.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertains to the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives, which includes AD/DHA-3/10 concerning the hand brake installation modification for Drover series aeroplanes. This legislation applies to all models of Drover series aeroplanes, demanding compliance with the outlined modifications to ensure safety standards are met. The directives are referenced through several documents, including DH Mod. DRO 77, DH TNS CT(A3) No. 79, and ANO 105.1.14.14.5.11, Issue 2. Compliance with these airworthiness directives must be achieved forthwith, meaning that the specified modifications must be implemented immediately. The regulations have a national reach, extending across the Commonwealth of Australia and applying to any entity or individual operating within its jurisdiction. There are no stated exclusions, exemptions, or thresholds specified in this particular directive, meaning that all Drover series aeroplanes must adhere to the requirements without exception. The application and enforcement of these regulations can be further extended or detailed through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Schedule of Airworthiness Directives DHA-3 (Drover) Series Aeroplanes, establish critical provisions for the airworthiness of certain aircraft models (sections 39 - 105, AD/DHA-3/10). The directive AD/DHA-3/10 mandates a modification to the hand brake installation in all Drover series aeroplanes. This modification is to be carried out in accordance with either DH Mod. DRO 77, DH TNS CT(A3) No. 79, or ANO 105.1.14.14.5.11, Issue 2, and compliance must be achieved forthwith. Entities governed by these regulations, including aircraft manufacturers, operators, and maintenance providers, must ensure that the specified modifications to the hand brake installation are completed without delay. This involves verifying that the installation adheres to the outlined documentation and standards to maintain the airworthiness of the aircraft. The primary obligation is to perform the modifications as specified and ensure that the aircraft remains compliant with safety standards post-modification. Failure to comply with these directives can result in severe consequences. The Civil Aviation Regulations impose both civil and criminal penalties for non-compliance. Civil penalties may include fines and legal actions to enforce compliance, while criminal penalties may involve imprisonment, reflecting the seriousness of ensuring airworthiness and safety in aviation. The exact penalties, including maximum fines and imprisonment terms, are detailed within the broader regulatory framework and should be referenced for specific details.
