AD/CESSNA 320/22 - Tip Tank Fuel Seepage - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, form a crucial part of the legislative framework governing civil aviation safety. The legislation aims to ensure that all aircraft operating within Australian airspace meet stringent safety standards. One specific regulation within this body of law is the Cessna 320 Series Aeroplanes AD/CESSNA 320/22 Tip Tank Fuel Seepage - Inspection, introduced to address the issue of fuel seepage in the wing tip fuel tanks of Cessna 320 series aircraft. This directive, effective from 30 April 1975, was established to mandate inspections and corrective actions to prevent potential safety hazards associated with fuel leaks. The policy objective behind this directive is to enhance flight safety by ensuring that any issues related to fuel seepage are identified and rectified promptly, thereby mitigating risks related to aircraft operations.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 applies to the Cessna 320 Series Aeroplanes with specific mandates through the Airworthiness Directives. This particular legislation, AD/CESSNA 320/22, targets all models of the Cessna 320 Series that are fitted with strobe lights in the wing tip fuel tank nose cap. The directive mandates a thorough inspection for tip tank fuel seepage, as detailed in either the CASA document SL ME73-4 or the Federal Aviation Administration (FAA) AD 75-05-08. Compliance is required within 100 hours of time in service after 30 April 1975, with subsequent inspections mandated at intervals not exceeding 100 hours of time in service. This directive ensures that the operational safety of the aircraft is maintained by regularly identifying and addressing potential fuel seepage issues. The geographic and jurisdictional reach of this directive is national, as it is governed by the Commonwealth of Australia through CASA, with no stated exclusions or exemptions in the provided text.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, section 105, outline the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the Cessna 320 series aeroplanes. The directive AD/CESSNA 320/22 addresses the issue of tip tank fuel seepage and mandates inspection procedures (Section 105.020). This directive applies to all models equipped with strobe lights in the wing tip fuel tank nose cap (Section 105.022). The applicable documents for compliance are either the Cessna SL ME73-4 or the FAA AD 75-05-08 (Section 105.024). The obligations under this directive require that inspections for tip tank fuel seepage be carried out on Cessna 320 series aeroplanes within 100 hours of time in service following 30 April 1975 and subsequently at intervals not exceeding 100 hours of time in service (Section 105.030). This ensures that any potential seepage issues are identified and addressed in a timely manner, thereby maintaining the airworthiness of the aircraft. Compliance with the specified inspection intervals is critical to ensuring the safety of the aircraft and its passengers. Failure to comply with the requirements outlined in the AD/CESSNA 320/22 directive can result in significant consequences. If an operator fails to adhere to the mandated inspection intervals or if the inspection does not meet the stipulated criteria, this can be considered a breach of the Civil Aviation Regulations (Section 105.040). Such breaches may lead to enforcement actions by CASA, which could include fines, suspension of air operator certificates, or other regulatory penalties (Section 105.050). In severe cases, the non-compliance could result in grounding of the affected aircraft until the issue is rectified, thereby impacting operational schedules and potentially leading to further financial and reputational consequences for the operator.
