AD/PA-30/10 - Fuel Selector Valve - Modification

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to ensure the safety and efficiency of civil aviation within Australia, addressing a need for comprehensive regulatory oversight of the industry. This legislative instrument, overseen by the Parliament of Australia, seeks to establish stringent safety standards and operational protocols to mitigate risks associated with civil aviation activities. Specifically, Part 39 - 105 within the Civil Aviation Regulations focuses on issuing airworthiness directives to maintain the safety of aircraft operations, with the overarching policy objective being the protection of public safety and the integrity of the national airspace. One such directive, AD/PA-30/10, pertains to the modification of the fuel selector valve for Piper PA-30 & 39 (Twin Comanche) series aeroplanes. This directive was introduced to address potential safety issues identified with the fuel selector valve in these aircraft models, requiring compliance within 100 hours of time in service following the directive's issuance on 31 August 1970. The directive references Piper SB No. 314 as the document detailing the required modifications. This directive is part of the broader framework established under the Civil Aviation Regulations 1998 to ensure that aircraft meet necessary safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which govern the safety standards and compliance requirements for aircraft within Australia. This particular directive, AD/PA-30/10, applies to Piper PA-30 and PA-39 (Twin Comanche) series aeroplanes with serial numbers ranging from 30-1 to 30-2000. The directive mandates that the fuel selector valve be modified, as detailed in Piper Service Bulletin No. 314, within 100 hours of time in service after 31 August 1970. The regulation's jurisdictional reach is governed by the Commonwealth of Australia, thereby extending its application nationally. While the directive is explicit in its requirements, the scope of its application is limited to the specified models and serial numbers of the Twin Comanche aeroplanes. The regulation does not explicitly state any exclusions, exemptions, or thresholds beyond the specified applicability criteria. The enforcement and interpretation of this directive may be supplemented by subordinate instruments issued by CASA, which can provide further clarification or additional requirements to ensure compliance.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), particularly Part 39 - 105, establish the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. Within this framework, AD/PA-30/10 pertains specifically to the modification of fuel selector valves for Piper PA-30 and PA-39 (Twin Comanche) series aeroplanes. This directive applies to model PA-30 with serial numbers ranging from 30-1 to 30-2000. Compliance with this directive must be achieved within 100 hours of time in service following 31 August 1970, as outlined in Piper Service Bulletin No. 314. The key requirement of AD/PA-30/10 (Section 39-105) is the modification of the fuel selector valve. This involves ensuring that the fuel selector valve is altered to comply with the specifications provided in Piper Service Bulletin No. 314. This modification aims to enhance the safety and reliability of the aircraft by preventing fuel system failures that could lead to hazardous situations during flight. Aircraft owners, operators, and maintenance providers governed by these regulations must adhere to AD/PA-30/10 by completing the specified modification within the stipulated timeframe. They are required to ensure that the aircraft meets the airworthiness standards set forth by CASA. This includes keeping accurate records of the modification process and ensuring that all relevant personnel are informed about the compliance requirements and the importance of adhering to the directive. Failure to comply with AD/PA-30/10 may result in significant consequences. Under the Civil Aviation Act 1988 (Cth), non-compliance can lead to enforcement actions, including fines and potential legal proceedings. The maximum penalty for contravening these regulations can be substantial, reflecting the importance of air safety and the potential risks associated with non-compliance. Additionally, non-compliance can result in the grounding of the aircraft until the required modifications are completed, which could disrupt operations and lead to further financial and logistical challenges for the operators.
