AD/B737/64 Amdt 1 - Forward Door Escape Slide

Overview

The Civil Aviation Regulations 1998, specifically Part 39, introduced Airworthiness Directives (ADs) to ensure the safety of aircraft operations. The AD/B737/64 Amendment 1 focuses on the forward door escape slide of Boeing 737 Series aeroplanes, particularly models 737-300, -400, and -500 series, to address issues identified with the escape slide velcro girt retaining straps. The legislation was enacted to respond to reports from the Federal Aviation Administration (FAA) about incorrectly routed and unserviceable escape slide straps, which could compromise the functionality of the escape slides during an emergency. This directive mandates compliance with FAA AD 96-18-04 Amendment 39-9728, which was adopted to ensure the safety and reliability of the escape slides, thereby enhancing the overall safety of aircraft operations. The Civil Aviation Safety Authority (CASA) issued this amendment to align with the FAA’s requirements, ensuring that Australian operators of the specified Boeing 737 series aircraft adhere to the same safety standards. This legislative measure aims to prevent potential hazards during emergency evacuations, thereby safeguarding passenger and crew safety. The policy objective is to maintain high safety standards in line with international best practices and to ensure the effective and timely dissemination of safety-critical information to aircraft operators.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, with Amendment 1 focusing on the Boeing 737 Series Aeroplanes. This legislation applies to Boeing 737-300, -400, and -500 series aircraft, with line numbers up to and including 2211, which are equipped with Air Cruisers forward door escape slides as detailed in Air Cruisers Company Service Bulletin 103-25-19, Revision 7. The primary concern addressed by this directive relates to the technical requirement for modifying the escape slide girts due to reports of incorrectly routed and unserviceable velcro girt retaining straps. Such conditions could potentially lead to unusable escape slides or jammed doors during an emergency evacuation. Compliance with this directive is mandated in accordance with the technical requirements outlined in FAA AD 96-18-04 Amendment 39-9728, with references to the FAA Principal Maintenance Inspector (PMI) interpreted as CASA District Office. The regulations ensure that all specified aircraft undergo necessary modifications to enhance safety during emergency evacuations, thus extending the jurisdictional reach of the Civil Aviation Regulations 1998 across the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, specify the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD) for Boeing 737 series aeroplanes. Specifically, AD/B737/64 Amendment 1 pertains to the forward door escape slide on models 737-300, -400, and -500 series aircraft, with line numbers up to and including 2211, equipped with Air Cruisers forward door escape slides as detailed in Air Cruisers Company Service Bulletin 103-25-19, Revision 7 (section 1). This directive applies to aircraft where the forward door escape slide has incorrectly routed and unserviceable Velcro girt retaining straps, a condition reported to the Federal Aviation Administration (FAA) that could potentially lead to unusable slides or jammed doors during an emergency evacuation. Entities governed by this Act are required to comply with the technical specifications outlined in FAA AD 96-18-04 Amendment 39-9728 (section 2). The directive mandates that the action taken must adhere to the requirements specified in the Requirement Document, with references to the FAA Principal Maintenance Inspector (PMI) interpreted as CASA District Office (section 3). Compliance with this AD is crucial to ensure the safety and functionality of the forward door escape slides in the event of an emergency. Failure to comply with the provisions of this Airworthiness Directive may result in severe consequences. Operators and entities must ensure that all modifications and actions are completed as specified, to avoid any potential risks to flight safety. Any non-compliance could be viewed as a breach of the Civil Aviation Regulations 1998, leading to enforcement actions by CASA. Although specific penalties are not outlined in this particular AD, non-compliance with CASA regulations generally can result in fines, enforcement notices, or other regulatory actions. The seriousness of non-compliance underscores the importance of adhering to the directive to maintain the highest safety standards in aviation.
