AD/B737/222 - Forward Door Escape Slide Stowage Compartments

Overview

The Civil Aviation Safety Regulations 1998, under Part 39 - 105, establish the framework through which the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (AD) to ensure the safety of aircraft and aeronautical products. Specifically, the Airworthiness Directive AD/B737/222, issued on 4 March 2004, addresses a safety concern regarding the forward door escape slide stowage compartments on Boeing 737-300, -400, and -500 series aircraft. This directive was enacted to rectify the issue where escape slides could potentially fall out of their compartments and inflate inside the aircraft, thereby obstructing evacuation routes during an emergency. The policy objective of this directive is to mitigate the risk of such unsafe conditions, thereby enhancing the overall safety of air travel. The directive references FAA AD 2004-02-08 Amdt 39-13443, with a revised compliance date of 15 April 2004, and was notified in the Commonwealth of Australia Gazette on 24 March 2004.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, encompasses Airworthiness Directives issued under the authority of the Civil Aviation Safety Authority (CASA). These directives apply to certain models of aircraft, such as the Boeing 737-300, -400, and –500 series, which must adhere to the specific requirements outlined in the directive. The purpose of these directives is to ensure the airworthiness and safety of the aircraft by mandating corrective actions to address identified safety concerns. In this instance, the directive addresses the potential unsafe condition where forward door escape slides could fall out of their stowage compartments, which could impede evacuation in an emergency. The directive requires compliance with the technical requirements specified in FAA AD 2004-02-08 Amdt 39-13443, with a revised effective date of 15 April 2004. The directive becomes effective on this date, and it is enforced throughout the Commonwealth of Australia. The scope of this Airworthiness Directive is limited to the specified aircraft models and does not extend to other types of aircraft or aeronautical products unless explicitly mentioned in other directives.

Key Provisions

The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 (CASR 1998) pertains specifically to the Boeing 737 Series Aeroplanes, as outlined in AD/B737/222. This directive, effective from 15 April 2004, mandates actions to prevent the forward door escape slides from falling out of their stowage compartments into the aircraft interior and inflating, which could potentially obstruct evacuation in an emergency. The directive applies to the Boeing 737-300, -400, and -500 series aircraft, as listed in Boeing Service Bulletin 737-25-1430 Revision 1 dated 10 April 2003. The required action must align with the technical requirements of FAA AD 2004-02-08 Amdt 39-13443 and should be carried out by the specified compliance date. The AD imposes obligations on the operators and owners of the specified Boeing 737 models to ensure they comply with the technical requirements outlined in the directive. This involves implementing the necessary measures to secure the forward door escape slides within their stowage compartments, thereby preventing any potential hazards during an evacuation. The directive requires adherence to the detailed instructions provided in the FAA AD 2004-02-08 Amdt 39-13443, which may include modifications or additional safety checks to ensure the integrity of the escape slide stowage systems. Operators must ensure that all actions are completed in accordance with the specified compliance date, which is set as 15 April 2004. Failure to comply with the AD may result in civil or criminal consequences. The regulations under CASR 1998 outline that non-compliance with an Airworthiness Directive can lead to enforcement actions, including fines, sanctions, and potential grounding of the aircraft. The specific penalties can vary based on the severity of the breach and the discretion of the Civil Aviation Safety Authority (CASA). In the case of serious breaches, the maximum penalties may include substantial fines and criminal charges, which could lead to imprisonment for the responsible parties. Ensuring adherence to the AD is crucial to maintaining the safety standards required under Australian aviation law.
