AD/PA-25/30 - Primary Control Cable Turnbuckles - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, were established to regulate civil aviation safety and ensure the safe operation of aircraft within Australian airspace. The specific legislative instrument F2006B05566 pertains to the Piper PA-25 (Pawnee) Series Aeroplanes and was introduced to address safety concerns associated with the primary control cable turnbuckles. This directive was intended to mitigate risks by mandating inspections of these critical components, ensuring they remain in a safe and operational condition. The policy objective is to maintain and enhance the safety standards in civil aviation by providing clear and enforceable directives that operators must adhere to, thereby protecting both the aircraft and those on board. The Civil Aviation Safety Authority, through this directive, aims to prevent potential failures of the primary control cable turnbuckles that could lead to catastrophic outcomes during flight. By setting a compliance window of within 100 hours time in service after 31 March 1971, the regulation ensures that all relevant aircraft are inspected and maintained according to stringent safety protocols. This legislative measure underscores the commitment to safeguarding the aviation industry and the public from hazards associated with aircraft malfunctions.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, mandates the inspection of primary control cable turnbuckles on Piper PA-25 (Pawnee) Series Aeroplanes. This legislation applies to all Piper PA-25 aircraft models with serial numbers ranging from 25-1 to 25-5293, encompassing aircraft registered and operating within Australia, thereby extending the Commonwealth's jurisdictional reach over these specific aircraft types. The directive necessitates compliance within 100 hours of time in service following 31 March 1971, as outlined in Piper Service Bulletin No. 328. This regulation does not explicitly mention any exclusions or exemptions, suggesting that all affected aircraft must adhere to the prescribed inspection requirements. The scope of this directive may be further elaborated or extended through subordinate instruments issued by the Civil Aviation Safety Authority, ensuring the ongoing safety and airworthiness of these aircraft.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 and specifically the Schedule of Airworthiness Directives (AD/PA-25/30), address the inspection of primary control cable turnbuckles for Piper PA-25 (Pawnee) Series Aeroplanes. This directive applies to all models with serial numbers ranging from 25-1 to 25-5293 (section 3/71). It mandates that the inspection of these turnbuckles must be conducted in accordance with Piper Service Bulletin No. 328. Furthermore, the compliance period for this directive is within 100 hours of time in service after 31 March 1971. The obligations imposed by this directive are clear and specific. Operators and owners of the affected Piper PA-25 Series Aeroplanes must ensure that the inspection of the primary control cable turnbuckles is performed as specified in Piper Service Bulletin No. 328. This includes adhering to the stipulated timeframe of within 100 hours of time in service after the specified date. Failure to comply with these requirements may result in serious safety implications and could lead to the aircraft being deemed unairworthy. Breaches of the provisions outlined in this Airworthiness Directive can result in significant consequences. While the specific penalties for non-compliance are not detailed within this directive, general provisions under the Civil Aviation Act 1988 may apply. Under this Act, non-compliance with airworthiness directives can result in civil penalties, including fines of up to $15,000 for individuals and $75,000 for corporations, as well as potential criminal charges that may lead to imprisonment. Additionally, the Civil Aviation Safety Authority (CASA) has the authority to issue directives to ground non-compliant aircraft, which could severely impact operations and lead to further financial and logistical burdens for the operators. In summary, the key provisions of this directive require all Piper PA-25 Series Aeroplanes with specified serial numbers to undergo an inspection of their primary control cable turnbuckles within a defined timeframe. Operators and owners must ensure compliance with the directive to maintain the airworthiness of their aircraft. Non-compliance can lead to severe civil and criminal penalties, along with enforcement actions by CASA that could result in the grounding of the aircraft.
