AD/CESSNA 190/1 Amdt 1 - Landing Gear Bulkhead Assembly

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aim to ensure the safety and regulation of civil aviation across the country. Specifically, Part 39 - 105 pertains to airworthiness directives, which are binding instructions issued by the Civil Aviation Safety Authority (CASA) to address safety issues in civil aircraft. This legislation is crucial in maintaining consistent safety standards and ensuring the reliability of aircraft operations. One such directive, AD/CESSNA 190/1, targets Cessna 190 and 195 Series Aeroplanes, requiring inspections of the landing gear bulkhead assembly to prevent structural failures, thereby safeguarding the integrity of these aircraft and protecting the lives of those on board. The AD/CESSNA 190/1 Amendment 1 directive, which became effective on 11 June 2007, addresses a specific safety concern regarding the landing gear bulkhead assembly in Cessna 190 and 195 Series Aeroplanes. The directive mandates inspections of certain components of the landing gear bulkhead assembly for cracking, particularly in the vicinity of the fuselage front spar attachments. This requirement applies to all models with more than 2,000 hours of total time in service, and inspections must be conducted at intervals not exceeding 200 hours total time in service. This directive exemplifies the Civil Aviation Regulations 1998's commitment to maintaining high safety standards in civil aviation by addressing potential structural vulnerabilities in specific aircraft models.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the authority and directives concerning the airworthiness of aircraft, and this particular legislative instrument applies to the Cessna 190 and 195 Series Aeroplanes. This legislation is a mandate for all aircraft models within the specified series that have accumulated more than 2000 hours of total time in service. It is a directive issued by the Civil Aviation Safety Authority, focusing on ensuring the integrity and safety of the landing gear bulkhead assembly. The regulation requires regular inspections of specific components of the landing gear bulkhead assembly to prevent and address potential cracking near the fuselage front spar attachments. These components include the front and rear door posts on both the left and right sides of the aircraft. Compliance with these inspections is mandated at intervals not exceeding 200 hours of total time in service, ensuring that any potential issues are identified and rectified promptly to maintain the airworthiness of the aircraft. The scope of this directive is national, applying across all jurisdictions within Australia and governed by the overarching Civil Aviation Regulations.

Key Provisions

The Civil Aviation Regulations 1998, particularly under Part 39 - 105, include a specific schedule of airworthiness directives that pertain to various aircraft models. For the Cessna 190 and 195 series aeroplanes, Amendment 1 addresses the landing gear bulkhead assembly (AD/CESSNA 190/1Amdt 1). This directive applies to all models that have accumulated more than 2000 hours of total time in service (section 1). The requirement stipulated by the directive is to inspect certain components of the landing gear bulkhead assembly, specifically focusing on potential cracking in areas near the fuselage front spar attachments (section 11/67). The components that must be inspected include the front door post on the left-hand side (P/N 0311156-6), the front door post on the right-hand side (P/N 0311156-7), the rear door post on the left-hand side (P/N 0311130-6), and the rear door post on the right-hand side (P/N 0311130-7) (section 11/67 (a)-(d)). The regulations impose specific obligations on the parties involved, such as aircraft operators and maintenance personnel, to ensure compliance with the airworthiness directive. The key obligation is to conduct the mandated inspections at intervals not exceeding 200 hours of total time in service (section 11/67). This requirement is designed to ensure that any potential structural issues are identified and addressed in a timely manner, thereby maintaining the aircraft's airworthiness and safety standards. Operators must maintain meticulous records of these inspections and any subsequent repairs or replacements to ensure traceability and compliance with the regulatory framework. Failure to comply with the airworthiness directive may result in serious civil and criminal consequences. While specific penalties are not detailed in the legislative instrument, non-compliance with airworthiness directives generally carries significant implications under the Civil Aviation Regulations. This can include enforcement actions by the Civil Aviation Safety Authority (CASA), potential grounding of the aircraft, and in severe cases, prosecution of individuals or entities responsible for the oversight of the aircraft's maintenance. The gravity of these consequences underscores the importance of adhering strictly to the stipulated requirements to ensure the safety and integrity of air operations.
