AD/AC-100/16 - Flap Quadrant - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were introduced to address the need for comprehensive safety regulations governing civil aviation within Australia. This legislation, overseen by the Civil Aviation Safety Authority, is intended to ensure the safety and reliability of aircraft operations. One specific aspect of these regulations, as demonstrated in the legislative instrument F2006B02168, is the issuance of airworthiness directives. This particular directive, AD/AC-100/16, mandates the replacement of the flap quadrant in S.L. Industries Commander 100 Series and Volair 10 Series aeroplanes. The policy objective here is to enhance the operational safety of these aircraft by addressing a specific component that may have safety implications if left unaddressed. The directive applies to all models with serial numbers ranging from 026 to 360 and 5001 to 5100, with compliance required within specific timeframes depending on the aircraft's hours of service. For aircraft that have accumulated over 300 hours of service by 30 April 1973, the replacement must occur within 100 hours after this date. For all other aircraft, the replacement must be completed before reaching 400 hours of service. This directive is part of a broader regulatory framework aimed at maintaining the highest standards of aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, mandate that certain directives apply to the maintenance and airworthiness of specific aircraft models within the Australian aviation industry. Specifically, the Airworthiness Directive AD/AC-100/16 pertains to the replacement of the flap quadrant in Aero Commander SL Industries Commander 100 Series and Volair 10 Series aeroplanes. This directive applies to all models with serial numbers ranging from 026 to 360 and from 5001 to 5100. Compliance with this directive is required for aircraft that have surpassed 300 hours of time in service as of 30 April 1973, necessitating the replacement within an additional 100 hours of time in service. For all other affected aircraft, compliance is required before reaching 400 hours of time in service. This regulation ensures that the specified aircraft meet the necessary safety standards and operational requirements set by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outline the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. One such directive, AD/AC-100/16, pertains to the replacement of the flap quadrant on S.L. Industries Commander 100 Series and Volair 10 Series aeroplanes (section 4/73). This directive applies to all models with specific serial numbers (S/Nos. 026 to 360 and 5001 to 5100). The directive references Aero Commander SL No. S-1205 as the document outlining the compliance requirements. Under this directive, the main requirement is that aircraft that have accumulated over 300 hours of time in service by 30 April 1973 must replace the flap quadrant within 100 hours of that date. For all other aircraft, the replacement must occur before they reach 400 hours of time in service (section 4/73). This ensures that the flap quadrants are replaced in a timely manner to maintain airworthiness standards. The obligations imposed by this directive are clear and specific. Aircraft operators must ensure that the flap quadrant replacement is carried out according to the stipulated timelines. Compliance involves closely monitoring the operational hours of the aircraft and ensuring that the replacement is performed by authorised personnel using the correct procedure as outlined in Aero Commander SL No. S-1205. Failure to comply with these directives can result in serious safety implications and potential penalties. For non-compliance with the airworthiness directives, there are significant consequences. The Civil Aviation Regulations 1998 provide for both civil and criminal penalties. Civil penalties may include fines, while criminal penalties could lead to imprisonment. The exact penalties depend on the severity and impact of the non-compliance, but the regulations are designed to ensure that airworthiness standards are strictly adhered to for the safety of all persons involved in aviation activities.
