AD/B747/89 - Flight Compartment Ashtray

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, aim to ensure the safety of civil aviation within the country. One specific legislative instrument within this act, F2006B03266, addresses an identified safety concern regarding the Boeing 747 Series Aeroplanes. This legislation was introduced to address the potential risk of fires caused by smoking materials in the flight compartment ashtray. The problem it seeks to resolve is the possibility of smoking material falling behind the sidewall lining of the ashtray when it is either partially opened or closed, which could lead to the ignition of a fire. The policy objective underpinning this regulation is to maintain and enhance aviation safety standards, ensuring that all aircraft operating in Australian airspace adhere to stringent safety protocols. The enacting body for these regulations is the Civil Aviation Safety Authority, which is responsible for ensuring that civil aviation activities in Australia are conducted in a safe and orderly manner. The regulation references FAA AD 91-03-16 Amdt 39-6875 and Boeing SB 747-25A 2862 Rev. 1, which outline the technical requirements and compliance specifications necessary to mitigate the identified risk. The revised effectivity date for Australian registered aircraft, as specified in the requirement document, is 18 April 1991, ensuring that all relevant aircraft are subject to the same stringent safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to Boeing 747 series aeroplanes, particularly those in the 747-400 series as identified in Boeing Alert SB 747-25A2862. This legislative instrument mandates compliance with the technical requirements of FAA AD 91-03-16 Amdt 39-6875, as referenced in Boeing Service Bulletin 747-25A 2862 Rev. 1. The purpose of this directive is to address the potential safety hazard associated with smoking materials falling behind the sidewall lining of flight compartment ashtrays, which can lead to the ignition of a fire if left uncorrected. Australian registered aircraft must adhere to these requirements with an effectivity date set as 18 April 1991. The regulations are applied nationally, overseen by the Civil Aviation Safety Authority, and any failure to comply could result in penalties or safety violations.

Key Provisions

The Civil Aviation Regulations 1998 (part 39 - 105) include an Airworthiness Directive (AD) concerning the Boeing 747 series aeroplanes, specifically targeting the flight compartment ashtray issue (AD/B747/89). This directive applies to model 747-400 series aeroplanes as listed in Boeing Alert SB 747-25A2862. The main requirement of this AD is that the action taken must comply with the technical specifications outlined in FAA AD 91-03-16 Amendment 39-6875. Australian registered aircraft must adhere to this directive, with a revised effectivity date of 18 April 1991, as indicated in the Requirement Document. This directive is a response to the potential risk of smoking materials falling behind the sidewall lining of the ashtray, which could occur when the ashtray is either partially opened or closed. If left unaddressed, this condition poses a significant risk of igniting a fire. Operators and owners of Boeing 747-400 series aircraft must ensure that the flight compartment ashtrays are modified in accordance with the technical requirements specified in FAA AD 91-03-16 Amdt 39-6875. This involves implementing the modifications outlined in Boeing Service Bulletin 747-25A 2862, Revision 1. These modifications are essential to prevent smoking materials from falling behind the sidewall lining, thereby mitigating the risk of fire. The directive mandates that these changes be made by the specified effectivity date, 18 April 1991, for aircraft registered in Australia. Compliance with these requirements is critical for maintaining the airworthiness of the aircraft and ensuring the safety of passengers and crew. Failure to comply with the provisions of AD/B747/89 can lead to serious consequences. Non-compliance with the AD could result in the aircraft being deemed unairworthy, which could prevent it from operating until the required modifications are made. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against operators who fail to adhere to the AD. These actions may include imposing fines, suspension of the aircraft’s operating certificate, or other regulatory measures deemed necessary to ensure compliance with aviation safety standards. The seriousness of the risk posed by non-compliance underscores the importance of adhering to the directive's requirements. In terms of penalties, while the specific penalties are not detailed in the text, the potential consequences of non-compliance can be severe. Regulatory bodies like CASA have the power to impose significant fines, and repeated or serious non-compliance can lead to more stringent penalties, including the suspension or revocation of an aircraft’s operating certificate. This could result in substantial financial loss for operators and could also lead to reputational damage. Additionally, there could be civil or criminal liability for any accidents or incidents that arise from non-compliance with airworthiness directives, further emphasising the importance of adhering to the AD requirements.
