AD/F28/21 - Passenger Door - Locking Mechanism Modification

Overview

The Civil Aviation Regulations 1998, as amended, include the regulations governing airworthiness directives for various aircraft, including the Fokker F28 Series Aeroplanes. One such directive, AD/F28/21, pertains to the modification of the passenger door locking mechanism for Fokker F28 aircraft. This directive was introduced to address specific safety concerns associated with the locking mechanism of the passenger doors on these aircraft, ensuring that such issues are rectified to maintain the safety standards required by the Civil Aviation Safety Authority (CASA). The legislation is enacted by the Australian Parliament and aims to ensure that all civil aviation activities within Australia adhere to stringent safety standards, thereby protecting the public and maintaining the integrity of the national aviation system. The problem this legislation addresses is the potential for passenger door locking mechanisms in Fokker F28 aircraft to fail, which could compromise the safety of passengers and crew. By mandating specific modifications to these mechanisms, the legislation aims to eliminate known safety risks associated with the aircraft's design. Compliance with this directive is mandatory, with a compliance deadline set before 31 October 1974, ensuring that all affected aircraft are modified in a timely manner to prevent any potential safety incidents.

Scope and Application

The Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority, specify the requirements for the airworthiness of Fokker F28 Series Aeroplanes, particularly in relation to the passenger door locking mechanism. This regulation applies to all aircraft operators who own or operate Fokker F28 Series aeroplanes within the Australian airspace and any other airspace where Australia has jurisdiction. The requirement is for compliance with the specifications outlined in Fokker SB F28/52-43, Part IV, which mandates modifications to the passenger door locking mechanism. Compliance with these modifications must be achieved before 31 October 1974 to ensure the aircraft continues to meet airworthiness standards. The regulation extends its reach through subordinate instruments, which may provide additional specifications or clarifications necessary for adherence to the airworthiness directives. There are no exclusions or exemptions specified in this directive, and the requirement applies universally to all Fokker F28 Series aeroplanes within the scope of the regulation.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, addresses the modification of the passenger door locking mechanism for Fokker F28 Series aeroplanes. This directive is denoted as AD/F28/21 and is detailed in Fokker Service Bulletin F28/52-43, Part IV. According to section (NK), this directive applies to Fokker F28 aircraft that must comply with the specified modifications before 31 October 1974. The directive requires that the passenger door locking mechanism of the Fokker F28 aeroplanes be modified as per the detailed instructions in the Fokker Service Bulletin F28/52-43, Part IV. This involves implementing specific technical changes to ensure the safety and reliability of the locking mechanism, which is crucial for the overall airworthiness of the aircraft. Operators of Fokker F28 aircraft are obligated to adhere to these modifications to maintain compliance with the airworthiness standards set by CASA. Failing to comply with the airworthiness directive AD/F28/21 could result in severe consequences. Under the Civil Aviation Act 1988, non-compliance may lead to enforcement actions by CASA, which can include fines, penalties, or other regulatory measures. The maximum penalties for non-compliance can vary, but they are designed to ensure that operators take the necessary actions to meet the airworthiness standards. Such actions are critical to maintaining the safety of air travel and preventing potential accidents related to the aircraft's door locking mechanism.
