SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 400 Series Aeroplanes
AD/CESSNA 400/51 Goodyear Fuel Cells - Inspection 6/78
Applicability: All models 401, 402, 411, 414 and 421 fitted with Goodyear BTC-39 fuel cells. Document: Cessna SL No. ME78-7.
Compliance: Within 100 hours time in service after 30 June 1978 and annually thereafter as detailed in Cessna SL No. ME78-7.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address the need for stringent safety standards in civil aviation, with Part 39 - 105 specifically concerning airworthiness directives to ensure the safety of aircraft in operation. The Civil Aviation Safety Authority (CASA) is the relevant body responsible for issuing these directives, aiming to maintain and improve the safety of aircraft. One such directive, AD/CESSNA 400/51, pertains to the inspection of Goodyear fuel cells in certain Cessna 400 series aeroplanes. This directive applies to all models 401, 402, 411, 414, and 421 equipped with Goodyear BTC-39 fuel cells and mandates compliance within 100 hours of time in service after 30 June 1978, followed by annual inspections as detailed in Cessna Service Letter (SL) No. ME78-7. The overarching policy objective is to ensure the ongoing airworthiness and safety of these aircraft through regular and rigorous inspections of critical components.
The Cessna 400 Series Aeroplanes AD/CESSNA 400/51 directive is a direct response to identified safety issues related to the fuel cells in specific Cessna models. By setting out clear and mandatory inspection requirements, the regulations aim to prevent potential failures that could compromise the safety of flights. CASA’s role in enforcing these directives ensures that all stakeholders adhere to the highest safety standards, thereby protecting passengers, crew, and the general public from aviation-related risks. This regulatory framework underscores the commitment to maintaining the integrity and reliability of civil aviation operations within Australia.
Scope and Application
The Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (AD) under the Civil Aviation Regulations 1998 to ensure the ongoing airworthiness of aircraft. Specifically, AD/CESSNA 400/51 pertains to all models of the Cessna 400 series aeroplanes, namely the 401, 402, 411, 414, and 421, that are fitted with Goodyear BTC-39 fuel cells. This directive applies to these aircraft regardless of their location within Australia, thereby extending its jurisdictional reach across the Commonwealth. Compliance with AD/CESSNA 400/51 requires an inspection within 100 hours of time in service after 30 June 1978 and annually thereafter, as detailed in Cessna Service Letter (SL) No. ME78-7. The directive mandates adherence to specific procedures to maintain the safety standards required by CASA, and failure to comply can result in penalties or the aircraft being deemed unairworthy. While the regulations are comprehensive, they do not explicitly state any exclusions or exemptions within the text, leaving room for potential clarifications through subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998 (Regulations) under Part 39 - 105, in particular, the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, include specific provisions for Cessna 400 series aeroplanes. Section AD/CESSNA 400/51 mandates the inspection of Goodyear Fuel Cells for models 401, 402, 411, 414, and 421 equipped with Goodyear BTC-39 fuel cells (Section AD/CESSNA 400/51). This directive applies to all the specified models, necessitating compliance with the detailed instructions provided in Cessna Service Letter (SL) No. ME78-7. The inspection is required within 100 hours of time in service after 30 June 1978 and annually thereafter.
Under these regulations, the aircraft operators and owners must ensure that the specified inspections are conducted as per the guidelines set out in Cessna SL No. ME78-7. This involves adherence to the technical specifications and procedures outlined to maintain the airworthiness of the aircraft. Failure to comply with these directives can result in the aircraft being deemed non-airworthy, which could lead to grounding of the aircraft and potential operational disruptions.
The Regulations impose significant obligations on the parties involved. Aircraft owners and operators must ensure that the Goodyear Fuel Cells are inspected and maintained according to the prescribed schedule and procedures. This includes documenting the inspections and ensuring that any necessary repairs or replacements are carried out by authorised personnel. Compliance with these directives is not only a legal requirement but also crucial for the safety and operational integrity of the aircraft.
Failure to comply with the airworthiness directives can result in serious consequences. The Regulations establish that non-compliance with the inspection and maintenance requirements can lead to enforcement actions by CASA. This includes the possibility of fines, legal penalties, and the suspension or revocation of the aircraft's airworthiness certificate. The maximum penalties can be substantial, reflecting the critical nature of ensuring the safety of aircraft operations. Operators and owners must, therefore, take these obligations seriously to avoid the associated risks and legal repercussions.
