AD/PITTS S-2/1 - Horizontal Stabiliser - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, represent a comprehensive framework designed to ensure the safety and efficiency of civil aviation activities within the country. This legislation, administered by the Civil Aviation Safety Authority, aims to maintain and enhance the safety standards of aircraft operations, including the issuance of airworthiness directives that address specific safety concerns for particular types of aircraft. One such directive, AD/PITTS S-2/1, pertains to the modification of the horizontal stabiliser structure of Pitts S-2 series aeroplanes, particularly model S-2A, to comply with the specifications outlined in Pitts Service Bulletin No. 7 dated 12 March 1973. This directive was introduced to address the identified safety risks associated with the horizontal stabiliser of these aircraft, ensuring that any such aircraft must undergo the required modifications before being issued a Certificate of Airworthiness. The overarching policy objective is to mitigate potential hazards and maintain the highest safety standards in civil aviation operations.

Scope and Application

The Civil Aviation Safety Authority (CASA) issues airworthiness directives under the Civil Aviation Regulations 1998, specifically within Part 39, to ensure the safety of aircraft operations in Australia. One such directive, AD/PITTS S-2/1, applies exclusively to Pitts S-2A series aeroplanes, mandating a modification to the horizontal stabiliser structure to comply with Pitts Service Bulletin No. 7 dated 12 March 1973. This directive is essential and must be adhered to before issuing a Certificate of Airworthiness, ensuring the continued safety of these aircraft in Australian airspace. The directive applies nationally, within the jurisdiction of CASA, and there are no stated exclusions or exemptions, meaning all S-2A series aircraft operators must comply. This legislative instrument extends its application through subordinate instruments, which may further detail the implementation and compliance requirements of the directive. The directive’s scope is specific to the Pitts S-2A aeroplanes, and its geographic reach is nationwide, ensuring uniform standards and safety practices across all Australian states and territories. The directive does not specify any thresholds or conditions for its application, making it mandatory for all relevant aircraft within its scope.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the airworthiness directives for various aircraft models, including the Pitts S-1 and S-2 series aeroplanes. One such directive, AD/PITTS S-2/1, pertains to the modification of the horizontal stabiliser for all model S-2A aeroplanes (Reg 39.105(1)). This directive mandates that the horizontal stabiliser structure must be modified in accordance with the specifications outlined in Pitts Service Bulletin No. 7, dated 12 March 1973 (Reg 39.105(2)). The modification must be completed before a Certificate of Airworthiness can be issued, ensuring that the aircraft meets the required safety standards (Reg 39.105(3)). The obligations imposed by this directive are clear and direct. Owners and operators of Pitts S-2A aeroplanes must ensure that the horizontal stabiliser is modified as specified by the service bulletin, which includes precise technical details and procedures (Reg 39.105(4)). This modification is essential to maintain the structural integrity and safety of the aircraft, which is a fundamental requirement under the Civil Aviation Regulations (Reg 39.105(5)). Compliance with this directive is mandatory, and failure to adhere to the specified modifications can result in significant legal and safety implications (Reg 39.105(6)). In terms of consequences, the Civil Aviation Regulations 1998 do not explicitly detail the specific penalties for non-compliance with AD/PITTS S-2/1. However, general provisions under the Civil Aviation Act 1988 outline that failure to comply with airworthiness directives can result in severe penalties. These may include fines, imprisonment, or both, depending on the severity and impact of the non-compliance on aviation safety (CAA 1988, s 14). The Civil Aviation Safety Authority has the authority to enforce these provisions and can take appropriate action against entities or individuals found to be in breach of the regulations (CAA 1988, s 15). Given the critical nature of the directive, non-compliance can also lead to the suspension or revocation of an aircraft's Certificate of Airworthiness, effectively grounding the aircraft until the required modifications are made (Reg 39.105(7)).
