AD/CESSNA 400/1 - Rear Fuselage Station 255 - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form a critical component of the regulatory framework governing aviation safety in the country. This legislation, along with its amendments, addresses various aspects of civil aviation, including aircraft airworthiness, operational standards, and safety regulations. One specific focus of the Civil Aviation Regulations 1998 is the issuance of Airworthiness Directives (ADs), which are legally enforceable rules aimed at correcting an unsafe condition of an aircraft. The ADs are issued by the Civil Aviation Safety Authority (CASA) to ensure that all aircraft meet the required safety standards. The overarching policy objective of these regulations is to maintain the highest possible safety standards in civil aviation, thereby protecting the lives of passengers, crew, and people on the ground. A particular example of an AD is AD/CESSNA 400/1, which pertains to the inspection of the rear fuselage station 255 of Cessna 400 Series aeroplanes. This directive was introduced to address specific safety concerns identified with certain model 411 aeroplanes, ensuring that these aircraft continue to meet airworthiness standards. The directive mandates inspections before a specified compliance date, aiming to mitigate potential safety risks associated with the identified structural issues. This regulation is part of a broader effort by CASA to proactively manage and mitigate safety risks in the civil aviation sector, thereby upholding the safety standards established under the Civil Aviation Regulations 1998.

Scope and Application

The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 specifically applies to all model 411 Cessna 400 Series aeroplanes with serial numbers ranging from 411-0001 to 411-0142, with the exclusion of certain serial numbers listed in the directive. This legislation mandates an inspection of the rear fuselage station 255 as outlined in AD/CESSNA 400/1, with a compliance deadline before 1 September 1971. This directive is applicable nationally across Australia, extending to all operators and entities within the civil aviation sector that own or operate the specified aircraft models. The directive is enforced by CASA, which is responsible for ensuring compliance with safety standards in Australian civil aviation. The scope of this directive does not extend to aircraft that were not manufactured before the specified date or those that have already been modified to comply with the requirements outlined in the directive. Additionally, CASA may issue subordinate instruments to further clarify or expand on the application of this directive, thereby ensuring ongoing safety and compliance within the aviation industry.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, particularly in relation to the Cessna 400 Series Aeroplanes, are outlined in AD/CESSNA 400/1. This directive mandates that specific models of the Cessna 400 series, namely all model 411 with serial numbers (S/Nos.) ranging from 411-0001 to 411-0142, undergo a rear fuselage station 255 inspection (section 39-105). However, certain serial numbers are exempt from this requirement, including 0068, 0072, 0076, 0099, 0102, 0105, 0112, 0119, 0129, 0130, 0132, 0133, 0138, 0139, and 0140. The obligations imposed by this regulation are specific to the identified Cessna 400 series model 411 aircraft within the specified serial number range. Owners or operators of these aircraft must ensure that the rear fuselage station 255 inspection is conducted as per the directive. This involves adherence to the guidelines provided in the referenced documents, Cessna SL 66-19 or DCA/CESSNA 411/1. Furthermore, compliance with this directive must be achieved before 1 September 1971. Failure to comply with the requirements set out in AD/CESSNA 400/1 may result in various consequences. The Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with this specific directive. However, under general aviation safety laws, non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions can include fines, operational restrictions, or more severe penalties if the non-compliance is found to contribute to safety risks. The exact nature and severity of the consequences would depend on the specifics of the non-compliance and the subsequent investigation by CASA.
