Overview

The Civil Aviation Regulations 1998, enacted in 1998, are the primary set of rules governing civil aviation in Australia, ensuring safety standards and procedures are adhered to. The 1998 Regulations, administered by the Civil Aviation Safety Authority (CASA), aim to maintain a safe and efficient civil aviation system by imposing stringent safety standards on all aircraft and aeronautical products operating within Australian airspace. The Airworthiness Directive (AD) is one of the mechanisms used under these Regulations to address specific safety concerns identified in particular aircraft types. In this instance, the AD was introduced to rectify a safety issue identified in CAP 232 Series Aeroplanes, specifically concerning the control stick floor cover which had the potential to restrict stick movement during aerobatic flights, posing a significant risk to flight safety. The AD/CAP 232/2, issued on 24 April 2001 and published in the Commonwealth of Australia Gazette on 2 May 2001, mandates corrective action to be taken for all CAP 232 aircraft within 10 hours of service after 2 May 2001, or if the action has already been completed. This directive follows an incident where the control stick floor cover moved during an aerobatics flight, restricting the pilot's control over the aircraft. The policy objective behind this AD is to ensure that the unsafe condition identified is corrected to prevent any recurrence of similar incidents, thereby maintaining the highest safety standards in the operation of CAP 232 aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses a range of requirements for ensuring the safety and airworthiness of aircraft and aeronautical products within Australia. One such regulation is the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). This AD applies to all CAP 232 series aeroplanes manufactured by CAP Aviation (Akrotech and Mudry). The directive mandates corrective actions to address a specific unsafe condition identified during an aerobatics flight where the control stick floor cover moved and restricted stick movement. The requirement for compliance with CAP Aviation Service Bulletin No. 000801, dated 8 September 2000, must be undertaken within 10 hours of time in service after the directive's effective date of 2 May 2001, unless the action has already been completed. This AD is issued under subregulation 39.1 (1) of the CAR 1998 and becomes effective immediately upon notification in the Commonwealth of Australia Gazette on the specified date.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, establish a framework for ensuring the safety of aircraft and aeronautical products. Within this framework, the Airworthiness Directive (AD) detailed under section 105 is a specific mandate issued to address identified safety issues. The AD for CAP Aviation (Akrotech and Mudry) CAP 232 Series Aeroplanes, identified as AD/CAP 232/2, is one such directive. This AD, which became effective on 2 May 2001, applies to all CAP 232 aircraft and requires specific action to address a safety issue related to the control stick cover (section 6/2001 DM). The AD mandates that the action stipulated in CAP Aviation Service Bulletin No. 000801, dated 8 September 2000, must be implemented. This action is intended to correct an unsafe condition identified during an aerobatic flight where the control stick floor cover moved and restricted the stick movement. This requirement must be adhered to within 10 hours of time in service after the directive's effective date, unless the action has already been completed. The directive is signed by David Alan Villiers, a delegate of the Civil Aviation Safety Authority, thereby officially endorsing the safety measures to be taken. Compliance with this AD is mandatory for all CAP 232 aircraft operators. They are required to ensure that the specified action is taken to rectify the unsafe condition, as outlined in the AD. Failure to comply with the directive could result in significant safety risks, potentially leading to compromised flight control and other safety hazards during aerobatic manoeuvres. The AD also references DGAC AD 2001-039(A), indicating alignment with international safety standards and directives. Failure to comply with the requirements set out in this Airworthiness Directive could have severe consequences. Such non-compliance might result in the aircraft being deemed unairworthy, which could lead to grounding of the aircraft and potential legal action against the aircraft operator. The Civil Aviation Regulations 1998 do not specify exact penalties within the AD itself but imply that non-compliance could result in significant civil or criminal penalties under other sections of the Regulations, including potential fines and imprisonment for those found in breach of safety mandates.
