AD/CESSNA 190/4 - Upper Landing Gear Bulkhead

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, introduces Airworthiness Directives that are integral to maintaining the safety standards of aircraft operations within Australia. This legislative instrument, designated F2006B05189, was enacted to address the need for regular inspections and maintenance of certain aircraft components to ensure they meet the required safety standards. The particular focus of this directive is on the Cessna 190 and 195 series aeroplanes, necessitating adherence to specific service bulletins to maintain airworthiness. The policy objective is to prevent potential structural failures and ensure the safety of passengers and crew by mandating regular and timely inspections and repairs of the upper landing gear bulkhead. This regulation was established by the Commonwealth of Australia, with the enactment body being the Parliament, ensuring the legislative framework supports the overarching goal of maintaining high safety standards in civil aviation. The directive stipulates that the required action must be taken within a specific timeframe after the publication date and at regular intervals thereafter, underscoring the commitment to proactive safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the issuance of airworthiness directives by the Civil Aviation Safety Authority, with the regulation AD/CESSNA 190/4 focusing on the Cessna 190 and 195 series aeroplanes. This regulation applies to all models within the Cessna 190 and 195 series, mandating that actions be taken in compliance with Cessna Service Letter SE73-15. The requirement necessitates compliance within 25 hours of time in service following the directive's issuance on 28 September 1973, and subsequent adherence to this directive must occur at intervals not exceeding 100 hours of time in service. This regulation operates within the Commonwealth of Australia, and its application extends to all entities operating within this jurisdiction, ensuring the continued safety and airworthiness of the specified aircraft models.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes the AD/CESSNA 190/4 directive concerning the upper landing gear bulkhead of Cessna 190 and 195 series aeroplanes. This directive (AD/CESSNA 190/4) applies to all models of the Cessna 190 and 195 series aeroplanes (Section 39 - 105). The directive requires that the upper landing gear bulkhead must be addressed in accordance with Cessna Service Letter SE73-15 (Section 39 - 105). Compliance with this directive is mandatory and must be completed within 25 hours of time in service after 28 September 1973. Following the initial compliance, the action must then be repeated at intervals not exceeding 100 hours of time in service (Section 39 - 105). The obligations imposed by this directive primarily involve the aircraft operators and maintenance personnel who must ensure that the upper landing gear bulkhead is inspected, maintained, or replaced as per Cessna Service Letter SE73-15. This includes conducting the required actions within the specified timeframes, which are within 25 hours after 28 September 1973 and subsequently at intervals not exceeding 100 hours time in service. Failure to adhere to these requirements can lead to non-compliance with airworthiness standards, potentially affecting the safety and certification status of the aircraft. Failure to comply with the AD/CESSNA 190/4 directive can result in various legal and safety consequences. The primary consequence is that the aircraft may be deemed unairworthy, which means it cannot be operated until the required maintenance action is completed. Additionally, there may be civil or criminal penalties imposed on the aircraft operator or maintenance personnel responsible for the oversight. The exact penalties and consequences can vary, but they can include fines and other enforcement actions by the Civil Aviation Safety Authority, potentially leading to suspension or revocation of the aircraft's certificate of airworthiness.
