AD/PA-23/35 Amdt 1 - Stabiliser Attachment Fittings - Inspection

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B05463, addresses specific safety concerns related to Piper PA-23 (Apache and Aztec) series aeroplanes, particularly focusing on the stabiliser attachment fittings. This legislative instrument was introduced to ensure the continued airworthiness and safety of these aircraft models by mandating regular inspections and compliance checks. The enacting body responsible for these regulations is the Commonwealth of Australia, specifically through the Civil Aviation Safety Authority (CASA), with a policy objective of maintaining high safety standards in the aviation industry. By setting forth detailed directives, the regulations aim to mitigate risks associated with structural integrity and ensure the safe operation of these aeroplanes within the Australian airspace.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, encompass the Civil Aviation Safety Authority's schedule of airworthiness directives for aircraft, including the Piper PA-23 (Apache and Aztec) series aeroplanes. This legislative instrument, F2006B05463, mandates that the stabiliser attachment fittings of the specified model aeroplanes must be inspected within 100 hours of their time in service after 2 November 1967. The directive applies directly to operators and owners of the PA-23 and PA-23-160 models, ensuring compliance with safety standards set forth by the Civil Aviation Safety Authority. This regulation extends its jurisdiction across the Commonwealth of Australia, thereby applying uniformly regardless of state or territory boundaries. The directive does not explicitly state any exclusions or exemptions, implying that all operators of the specified aeroplanes must adhere to the inspection requirements as outlined. The scope of the legislation is further extended through subordinate instruments, which may provide additional details or amendments to the primary directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105 and the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for Piper PA-23 (Apache and Aztec) Series Aeroplanes, includes an amendment (AD/PA-23/35) relating to the inspection of stabiliser attachment fittings (paragraph 12/67). This amendment applies to aircraft models PA-23 and PA-23-160. The directive mandates that compliance must be achieved within 100 hours of time in service following 2 November 1967, as outlined in the Ansett General Aviation Service Bulletin No. 7. This legislation imposes specific obligations on the owners and operators of the affected aircraft models. The primary requirement is to ensure that the stabiliser attachment fittings are inspected within the stipulated timeframe. This inspection must be conducted by authorised personnel who are qualified to carry out such maintenance and ensure that the fittings comply with the safety standards prescribed by CASA. The directive also mandates that any discrepancies or issues identified during the inspection must be rectified immediately to maintain the airworthiness of the aircraft. Failure to comply with the airworthiness directive can result in serious legal and safety repercussions. CASA has the authority to enforce penalties for non-compliance, which may include fines, suspension of the aircraft’s certificate of airworthiness, or other regulatory actions. The potential penalties reflect the critical nature of the stabiliser attachment fittings in maintaining the structural integrity and safety of the aircraft. Although specific maximum penalties are not detailed in the provided text, they can be substantial, reflecting the severity of non-compliance with airworthiness directives. In addition to the regulatory enforcement, there are significant safety implications for non-compliance. Defects in the stabiliser attachment fittings could lead to serious in-flight incidents, potentially resulting in loss of control, structural failure, or other catastrophic outcomes. The directive is thus a critical component of the overarching framework aimed at ensuring the highest standards of aviation safety are maintained across the industry. Compliance with such directives is not only a legal obligation but also a fundamental aspect of the duty of care owed to passengers, crew, and other individuals on the ground.
