AD/PA-25/18 - Jury Strut - Modification

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B05555, address the problem of ensuring the airworthiness of specific aircraft models, particularly the Piper PA-25 (Pawnee) Series Aeroplanes, by introducing specific safety directives. This legislative instrument was enacted to enhance aviation safety by establishing a clear and mandatory schedule of airworthiness directives that operators must comply with. The Civil Aviation Safety Authority (CASA), the body responsible for enforcing these regulations, aims to ensure that aircraft maintain a high standard of safety through these directives. The overarching policy objective is to protect public safety and prevent accidents by requiring specific modifications or inspections on aircraft that have been identified as having potential safety issues.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to the Piper PA-25 (Pawnee) Series Aeroplanes with serial numbers ranging from 25-1 to 25-399. This regulation mandates modifications to the jury strut as outlined in Piper Service Letter No. 403, with compliance required before 1 September 1971. The directive is applicable nationwide, encompassing all civil aviation operations within the Commonwealth of Australia. The legislation is intended to ensure that specified aircraft meet the required airworthiness standards, thereby enhancing safety in civil aviation. Any non-compliance with this directive could result in the aircraft being deemed unairworthy, impacting its ability to legally operate within Australian airspace. While the primary focus of this regulation is the modification of jury struts, it is essential to note that the scope is limited to the specified model and serial number range of the Piper PA-25 series aeroplanes.

Key Provisions

The Civil Aviation Regulations 1998, Part 39, under the Schedule of Airworthiness Directives, specifically addresses the Piper PA-25 (Pawnee) Series Aeroplanes through AD/PA-25/18. This directive mandates a modification to the jury strut, as detailed in Piper SL No. 403 (Section 39-105). The directive applies to aircraft with serial numbers (S/Nos.) ranging from 25-1 to 25-399, which must comply with these requirements before 1 September 1971. This means that all owners and operators of these specific aircraft must ensure that the modifications are completed by this date to maintain compliance with safety standards. The obligations imposed by AD/PA-25/18 are clear and specific. Owners and operators of the affected Piper PA-25 aircraft must follow the detailed instructions provided in Piper SL No. 403 to modify the jury strut as specified. This modification is essential to address identified safety issues and ensure the continued airworthiness of the aircraft. Failure to comply with these requirements can lead to serious safety implications, which is why the regulations are stringent about the compliance deadline. Non-compliance with AD/PA-25/18 can result in significant consequences. Under the Civil Aviation Regulations 1998, failure to adhere to the Airworthiness Directives can be considered a breach of safety regulations. This breach may result in penalties, including fines or other civil sanctions, as outlined in the regulations. In more severe cases, non-compliance could lead to the grounding of the aircraft, preventing it from flying until the required modifications are completed. The specific penalties are not detailed in the extract but are typically commensurate with the severity and impact of the non-compliance.
