SCHEDULE OF AIRWORTHINESS DIRECTIVES
DHC-3 (Otter) Series Aeroplanes
AD/DHC-3/22 Elevator Tab Control Arm 10/67
Applicability: All models.
Requirement: Action in accordance with De H Canada SB No 3/4. Compliance: Within 50 hours time in service after 2 November 1967.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, are a comprehensive set of rules governing civil aviation in Australia, designed to ensure the safety and efficiency of air travel. Part 39, which includes the Airworthiness Directives, addresses the ongoing maintenance and operational standards for aircraft, with AD/DHC-3/22 being an example that specifies requirements for the elevator tab control arm of DHC-3 (Otter) series aeroplanes. This directive was introduced to address specific safety concerns identified in the operation of these aircraft, ensuring compliance with international standards and improving overall aviation safety.
The policy objective of these regulations is to maintain a high standard of airworthiness for all aircraft operating in Australian airspace, thereby protecting the public and contributing to the safe, orderly, and efficient development of civil aviation. The Civil Aviation Safety Authority (CASA) enforces these regulations, ensuring that all aircraft meet the necessary safety standards, thereby mitigating risks associated with aviation operations.
Scope and Application
The Civil Aviation Regulations 1998, as specified in PART 39 - 105 under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, pertain to the DHC-3 (Otter) series aeroplanes, with particular focus on AD/DHC-3/22, which addresses the elevator tab control arm. This legislation applies to all models of the DHC-3 series, mandating compliance with the requirements set forth by De H Canada Service Bulletin No 3/4. The directive necessitates that the specified action be completed within 50 hours of the aeroplane's time in service following 2 November 1967. The scope of this Act encompasses the maintenance and safety standards applicable to the designated aircraft models, ensuring adherence to the outlined directives to maintain airworthiness and safety within the Australian civil aviation sector. Although the regulations themselves do not specify geographic limitations beyond the Commonwealth, their application extends to all entities operating within Australia that possess or utilise the DHC-3 series aeroplanes. Additionally, the regulations do not provide explicit details on exclusions or exemptions, thereby implying that all relevant entities and aircraft must comply unless otherwise specified through subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998 (Regulations) under Part 39 - 105, specifically the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for DHC-3 (Otter) Series Aeroplanes, includes AD/DHC-3/22 (Section 10/67). This directive pertains to the elevator tab control arm and mandates action in accordance with De H Canada Service Bulletin No 3/4. The directive applies to all models of the DHC-3 Otter series aeroplanes. The requirement is to comply with the specified action within 50 hours of time in service after 2 November 1967.
Under this legislation, the primary obligation for the operators and owners of DHC-3 (Otter) series aeroplanes is to ensure that the elevator tab control arm is addressed according to De H Canada Service Bulletin No 3/4. This involves performing the necessary actions to maintain or rectify the condition of the elevator tab control arm within the stipulated timeframe of 50 hours of time in service post the directive date of 2 November 1967. This requirement is essential to ensure the airworthiness and safety of the aircraft in question.
Failure to comply with the provisions set out in AD/DHC-3/22 could lead to serious consequences. Although the Regulations do not explicitly state the penalties or consequences for non-compliance with this specific directive, general provisions in the Civil Aviation Act 1988 and Civil Aviation Regulations 1998 do provide for potential enforcement actions. These could include fines, legal proceedings, and potentially grounding of the aircraft until the directive is complied with. It is important for operators and owners to adhere to the directive to avoid any legal repercussions or safety hazards.
