AD/CESSNA 340/8 - Tip Tank Fuel Seepage - Inspect

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as the primary regulatory framework governing civil aviation safety in Australia. Among its many provisions, Part 39 addresses Airworthiness Directives, which are legally enforceable rules related to the design, construction, maintenance, and operation of aircraft. A specific legislative instrument, F2006B08285, targets the Cessna 340 Series Aeroplanes with AD/CESSNA 340/8, addressing the issue of fuel seepage in the wing tip tanks. This legislative measure was introduced to ensure the safety and airworthiness of these aircraft by mandating regular inspections to prevent potential hazards associated with fuel leaks. The policy objective is to maintain stringent safety standards and ensure compliance with international civil aviation safety regulations.

Scope and Application

The Civil Aviation Regulations 1998, under the jurisdiction of the Civil Aviation Safety Authority, include specific Airworthiness Directives for maintaining the safety of aircraft operations. One such directive, AD/CESSNA 340/8, pertains to the inspection of tip tank fuel seepage for all models of Cessna 340 series aeroplanes that are equipped with strobe lights in the wing tip fuel tank nose cap. This requirement is mandated by either the document Cessna SL ME73-4 Part II Item 2 or the FAA AD 75-05-08, and it necessitates compliance within 100 hours of time in service after 30 April 1975, and subsequently at intervals not exceeding 100 hours of time in service. This regulation applies broadly across the Commonwealth of Australia, ensuring consistent safety standards for the operation of these aircraft within its airspace. The scope of the directive ensures that any aircraft owner or operator within Australia must adhere to these inspection protocols to maintain compliance with civil aviation safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, detail the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives concerning Cessna 340 Series Aeroplanes. One key provision of this legislation is AD/CESSNA 340/8, which pertains to tip tank fuel seepage inspections (section 4/75). This directive applies to all models of Cessna 340 aeroplanes that are fitted with strobe lights in the wing tip fuel tank nose cap. The directive references two specific documents for compliance: either Cessna SL ME73-4 Part II Item 2 or FAA AD 75-05-08. The obligations imposed by AD/CESSNA 340/8 are clear and straightforward. Operators of affected Cessna 340 aeroplanes must ensure that inspections for fuel seepage are conducted within 100 hours of time in service after 30 April 1975. After the initial inspection, these inspections must be repeated at intervals not exceeding 100 hours of time in service. These requirements are designed to maintain the airworthiness of the aircraft by identifying and rectifying any potential issues with fuel tank integrity. Failure to comply with the airworthiness directive could lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with CASA regulations can result in enforcement actions. Such actions may include fines, suspension or revocation of air operator certificates, and potential criminal charges against individuals responsible for the oversight of the aircraft. The seriousness of these penalties reflects the importance of adhering to airworthiness directives to ensure the safety of all persons on board and the integrity of the aviation system.
