Overview
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, encompass a schedule of airworthiness directives aimed at ensuring the safety and operational integrity of aircraft within Australia. The legislation, enacted by the Commonwealth of Australia, addresses the need for consistent and stringent safety standards for civil aviation. The policy objective is to mitigate risks associated with aircraft operation by mandating specific directives, such as those outlined for the Cessna 185 Series Aeroplanes. One such directive, AD/CESSNA 185/18, pertains to the wing strut attachment strap, applicable to model 185 with serial numbers ranging from 18502199 to 18502238. This directive requires compliance with Cessna Service Letter SE73-20, mandating corrective action within 100 hours of time in service following 24 September 1973. This legislation is integral in maintaining the high safety standards required for civil aviation operations in Australia.
Scope and Application
The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directives under the Civil Aviation Regulations 1998, specifically targeting the Cessna 185 Series Aeroplanes. The directive applies to all model 185 aircraft with serial numbers ranging from 18502199 to 18502238. This particular directive mandates that action be taken in accordance with Cessna Service Letter SE73-20, which addresses the wing strut attachment strap. Compliance with this directive is required within 100 hours of time in service after the directive was issued on 24 September 1973. The scope of this legislation is confined to the specified aircraft models within the stated serial number range and pertains exclusively to the issue of the wing strut attachment strap. The regulation does not extend to other aircraft models or serial numbers outside the specified range. Additionally, the directive operates within the jurisdictional reach of the Commonwealth of Australia, as it is issued by CASA, which is the national regulator for civil aviation safety.
Key Provisions
The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under Part 39 of the Civil Aviation Regulations 1998, specifically in Schedule 105 (AD/CESSNA 185/18) pertaining to the Cessna 185 series aeroplanes. This AD is concerned with the wing strut attachment strap on models 185 with serial numbers ranging from 18502199 to 18502238. According to the directive, the action required to ensure compliance is in accordance with Cessna Service Letter SE73-20 (section 9/73). This entails implementing specific modifications or checks as detailed in the referenced service letter. Compliance with this AD must be achieved within 100 hours of time in service after the directive's effective date of 24 September 1973.
The AD imposes several obligations on the operators and owners of the affected Cessna 185 series aeroplanes. They must ensure that the necessary modifications or checks outlined in Cessna Service Letter SE73-20 are performed on the wing strut attachment straps of their aircraft within the specified timeframe. This requirement aims to maintain the airworthiness and safety of these aircraft by addressing potential structural issues that could compromise the integrity of the wing strut attachment. Operators must keep detailed records of the actions taken to comply with this directive, including the date of compliance and the signatures of the authorised personnel who carried out the work.
Failure to comply with the requirements of this AD may result in significant legal and operational consequences. While the specific consequences are not detailed within the AD itself, under the broader framework of the Civil Aviation Regulations 1998, non-compliance could potentially lead to enforcement actions by CASA. Such actions could include fines, suspension or revocation of the aircraft's certificate of airworthiness, and possibly criminal charges for serious breaches. The penalties for non-compliance can vary, but they are designed to ensure that operators take the necessary steps to maintain the safety standards required by Australian aviation regulations. The seriousness of these consequences underscores the importance of adhering to CASA's directives to prevent potential safety hazards.
