Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, address the issue of ensuring the airworthiness of aircraft through various directives, including those for the Cessna 150, F150, 152, and F152 series aeroplanes. This regulation was enacted to maintain safety standards in civil aviation by addressing potential structural failures. The problem it seeks to resolve is the risk of longitudinal cracks in the AN 155 brass turnbuckles of the specified models, which could compromise the flying control system's integrity. The regulation was introduced by the Commonwealth of Australia, with the policy objective of ensuring that all applicable aircraft comply with specific maintenance actions to prevent structural failure and enhance safety. The enactment body responsible for these regulations is the Civil Aviation Safety Authority, ensuring that the directives are in line with the overarching goal of maintaining safe and reliable aviation practices in Australia.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the application of Airworthiness Directives (ADs) concerning the safety of civil aviation. This legislation applies to all models of Cessna 150, A150, 152, A152, F152 and FRA152 aeroplanes with specific serial numbers, which must comply with the directive to ensure the safety of their flying control systems. The directive is aimed at addressing a potential issue with the AN 155 brass turnbuckles in the control system, which may develop longitudinal cracks. Compliance with the AD is mandatory, requiring actions to be taken within 100 hours of the aeroplane's time in service after 30 April 1980, in accordance with Cessna Service Instruction Letter SE80-16. The geographic reach of this regulation is nationwide, governing all civil aviation activities within the Commonwealth of Australia. The regulation does not specify any exclusions, exemptions, or thresholds, indicating that all specified aircraft must adhere to the outlined safety measures. The application of these regulations may be further detailed or extended through subordinate instruments, ensuring the comprehensive safety of civil aviation operations.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (AD) that govern the maintenance and operational standards of certain aircraft. One such AD, AD/CESSNA 150/35, pertains to the flying control system turnbuckles for Cessna 150, A150, 152, A152, F152, and FRA152 series aeroplanes with specified serial numbers (section 1). The AD mandates actions in accordance with Cessna Service Information Letter (SIL) No. SE80-16 and requires compliance within 100 hours of time in service after 30 April 1980 (section 2). The directive addresses the potential presence of longitudinal cracks in the AN 155 brass turnbuckles used in the control system (section 3).
The AD imposes specific obligations on the owners and operators of the affected Cessna aircraft. They must ensure that the flying control system turnbuckles are inspected and, if necessary, replaced or repaired to meet the specifications outlined in Cessna SIL No. SE80-16. This involves identifying the affected turnbuckles and taking appropriate corrective actions to maintain the airworthiness of the aircraft (section 4). Compliance must be achieved within the stipulated timeframe of 100 hours after the effective date of the AD, ensuring that the aircraft remains compliant with safety regulations.
Failure to comply with the AD may result in serious safety implications, and the AD itself does not specify penalties. However, non-compliance with ADs can lead to enforcement actions under the Civil Aviation Act 1988, including potential fines and criminal charges. The Civil Aviation Safety Authority (CASA) may take regulatory action against operators who fail to adhere to ADs, which can include grounding the aircraft, imposing fines, or pursuing legal action against the responsible parties (section 5). The exact penalties would depend on the severity of the non-compliance and the specific circumstances of the case.
