AD/PA-36/10 - Spray Pump Windmill - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, address a specific safety concern related to the operation of Piper PA-36 (Pawnee Brave) series aeroplanes. In particular, Airworthiness Directive (AD) AD/PA-36/10 was introduced to ensure the safety of aeroplanes within certain serial number ranges that are equipped with Agrinautics liquid dispersal equipment. This legislative instrument was designed to rectify issues identified with the spray pump windmill, necessitating a modification to ensure continued compliance with aviation safety standards. The directive requires compliance before further flight after 12 December 1975, underscoring the urgency and importance of addressing this safety issue. The policy objective behind AD/PA-36/10 is to mitigate potential risks associated with the identified equipment, ensuring that all affected aircraft meet necessary safety requirements before resuming flight operations.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 105, mandate airworthiness directives for civil aircraft, including the Piper PA-36 (Pawnee Brave) Series Aeroplanes, as outlined in AD/PA-36/10. This directive applies to all model PA-36 aeroplanes with serial numbers ranging from 36-7360001 to 36-7560028, 36-7560030 to 36-7560033, and 36-7560036 to 36-7560041, provided they are equipped with Agrinautics liquid dispersal equipment. The directive pertains to modifications required to the spray pump windmill and must be adhered to before any further flight after 12 December 1975, as detailed in Piper Service Bulletin No. 467. The regulations extend across the Commonwealth of Australia, impacting the aviation industry and ensuring compliance with safety standards through CASA. The directive does not specify any exclusions, exemptions, or thresholds, but its application may be further detailed or extended by subordinate instruments issued by CASA.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically in PART 39 - 105, include AD/PA-36/10, which pertains to the airworthiness directives for Piper PA-36 (Pawnee Brave) series aeroplanes. This directive, as referenced in section 1/76, mandates modifications to the spray pump windmill for certain model PA-36 aeroplanes. According to the applicability outlined in the legislation, this directive applies to all model PA-36 aeroplanes with specific serial numbers, including those from 36-7360001 to 36-7560028, 36-7560030 to 36-7560033, and 36-7560036 to 36-7560041, provided they are equipped with Agrinautics liquid dispersal equipment. Compliance with this directive, as stipulated in Piper SB No. 467, must be achieved before any further flight is undertaken after 12 December 1975. The obligations and requirements imposed by this legislation on the parties or entities it governs are quite specific. Owners and operators of the affected Piper PA-36 aeroplanes must ensure that the modifications to the spray pump windmill are completed as specified in Piper SB No. 467. This involves adhering to the technical instructions and standards set forth by the Civil Aviation Safety Authority (CASA) to maintain the airworthiness of these aircraft. Ensuring compliance with these directives is essential to meet the safety standards set by the Civil Aviation Regulations, and failure to do so can have significant implications. The legislation also outlines the potential offences, penalties, and consequences for non-compliance with the airworthiness directives. Although the specific penalties are not detailed in the text provided, breaches of these regulations can generally result in severe civil and criminal consequences. In Australia, non-compliance with Civil Aviation Regulations can lead to penalties that may include fines, imprisonment, or both. The severity of the penalty would depend on the specific breach and the discretion of the court, but it is clear that adherence to these directives is not optional for those operating these aircraft. In summary, the Civil Aviation Regulations 1998, as detailed in PART 39 - 105, mandate specific modifications to the spray pump windmill for certain Piper PA-36 aeroplanes to ensure continued airworthiness. The obligations on the operators of these aircraft are clear: they must comply with the specified directives to ensure safety and regulatory adherence. Failure to comply with these regulations can result in significant penalties, highlighting the importance of strict adherence to the directives outlined by CASA.
