AD/B767/38 Amdt 2 - Engine Fire and Overheat Detection System

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive set of rules designed to ensure the safety and efficiency of civil aviation within the country. One specific area addressed by these regulations is the issuance of Airworthiness Directives (ADs) to maintain aircraft safety standards. For instance, AD/B767/38 Amendment 2, issued under PART 39 - 105 of the Civil Aviation Regulations, targets the Boeing 767 series aeroplanes equipped with Kidde engine fire and overheat detection systems. This directive was introduced to address the issue of numerous false fire and overheat warnings that had led to engine in-flight shutdowns and aircraft diversions, thereby compromising the safe operation of these aircraft. The policy objective behind this amendment is to ensure that these systems are modified correctly to prevent such incidents, thereby maintaining the highest safety standards in Australian airspace. Compliance with this directive is mandatory and must be achieved by 31 March 1994.

Scope and Application

The Civil Aviation Safety Authority (CASA) regulations, specifically Part 39 - 105 of the Civil Aviation Regulations 1998, mandate the compliance with Airworthiness Directives for certain aircraft, including Boeing 767 series aeroplanes equipped with Kidde engine fire and overheat detection systems. These regulations apply to all model 767 series aeroplanes that meet the specific criteria outlined in Boeing Service Bulletin 767-26-0037 Revision 3 dated 8 July 1993. The directive requires modifications to the engine fire and overheat detection systems to address the identified safety issues, such as false fire and overheat warnings, which have led to engine shutdowns and aircraft diversions. Compliance with this directive is mandatory and must be completed by 31 March 1994, unless previously accomplished. The directive extends its reach by referencing FAA AD 90-05-05 Amendment 39-6516, ensuring that the modifications align with international standards and practices. The CASA retains the authority to issue amendments to the directive, as demonstrated by the issuance of Amendment 1 and Amendment 2 to address evolving safety concerns and additional work requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish critical safety requirements for the operation of Boeing 767 series aeroplanes fitted with Kidde engine fire and overheat detection systems. Section (AD/B767/38) mandates modifications to the engine fire and overheat detection system, as detailed in Boeing Service Bulletin 767-26-0037 Revision 3 dated 8 July 1993. This directive applies to all Boeing 767 series aeroplanes equipped with the specified Kidde systems, as referenced in the Service Bulletin. The requirement is for these systems to be modified to address issues of false fire and overheat warnings that have previously caused engine shutdowns and diversions in flight, which could potentially compromise the safety of the aircraft. Operators of Boeing 767 series aeroplanes with Kidde engine fire and overheat detection systems must ensure compliance with the modifications outlined in the Service Bulletin. This obligation involves implementing the specified changes to the detection system to prevent false warnings, which could lead to unnecessary engine shutdowns or diversions. Compliance with this directive is mandatory, with the requirement to complete the modifications before 31 March 1994 unless the work has already been completed. The directive aims to enhance the reliability and safety of the aircraft by addressing the identified issues with the fire detection systems. Failure to comply with the requirements of the Airworthiness Directive could result in significant civil and criminal consequences. Although the specific penalties are not detailed in the text, non-compliance with airworthiness directives is generally subject to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, operational restrictions, or more severe penalties for repeated or severe breaches of safety regulations. The exact penalties would be determined based on the nature and severity of the non-compliance, but the potential for significant regulatory action underscores the importance of adhering to the directive. In summary, the Civil Aviation Regulations mandate that operators of Boeing 767 series aeroplanes fitted with Kidde engine fire and overheat detection systems must modify these systems as specified in Boeing Service Bulletin 767-26-0037 Revision 3. Compliance is required by 31 March 1994 to prevent false fire warnings that could lead to dangerous in-flight shutdowns or diversions. Non-compliance carries the risk of substantial penalties and regulatory action by CASA, highlighting the critical importance of adhering to these safety directives.
