AD/BAe 146/41 - Call Panel Mountings

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, introduces Airworthiness Directives (ADs) to ensure the safe operation of aircraft within Australian airspace. Specifically, AD/BAe 146/41 addresses safety concerns related to the British Aerospace BAe 146 Series Aeroplanes, focusing on the mountings of the 2L Call Panels. This directive was enacted by the Civil Aviation Safety Authority (CASA) to rectify an issue identified in tests showing that the 2L Call Panel Mountings did not comply with current flammability standards for cabin interior materials. The problem this AD seeks to address is the potential risk of fire within the aircraft's cabin, which could compromise passenger and crew safety. The policy objective is to mandate compliance with the British Aerospace Service Bulletin 25-294-36108B, ensuring that specified models of the BAe 146 Series meet the necessary safety standards before June 6, 1992. This legislative instrument underscores the importance of stringent safety measures in civil aviation, aiming to prevent incidents related to flammable materials in aircraft cabins. By implementing this directive, CASA ensures that operators of the affected BAe 146 Series aeroplanes adhere to critical safety protocols, thereby mitigating potential hazards and maintaining high standards of airworthiness.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, governs the mandatory compliance of British Aerospace BAe 146 Series Aeroplanes regarding call panel mountings. This regulation applies to specific models of the BAe 146 series, including Series 200 and 300, and their respective sub-models as identified by their constructor's numbers. The directive requires adherence to Mandatory British Aerospace 146 Service Bulletin 25-294- 36108B, which outlines the necessary actions to ensure compliance with current cabin interior material flammability standards. Compliance with these directives must be achieved unless the required actions have already been completed prior to 6 June 1992. This regulation is intended to ensure the safety and airworthiness of the specified aircraft models by addressing the identified flammability issues with the 2L Call Panel Mountings. The scope of this regulation extends to the Commonwealth of Australia, enforcing the safety directives across all jurisdictions within the country. The regulation does not specify any exclusions, exemptions, or thresholds beyond the outlined applicability to the listed BAe 146 Series Aeroplane models. While the primary regulation is set out in the Civil Aviation Regulations 1998, further details and extensions of the application may be provided through subordinate instruments issued by CASA. These instruments may offer additional guidance or specific implementation details necessary to achieve compliance with the safety directives.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, mandate the adherence to Airworthiness Directives (AD) for the British Aerospace BAe 146 Series aeroplanes, as detailed in AD/BAe 146/41 concerning Call Panel Mountings (section 3/92). This directive applies to specific model numbers within the BAe 146 Series, namely Series 200 and 300, with particular constructor’s numbers listed. The requirement outlined in this directive mandates that corrective actions must be taken in accordance with the Mandatory British Aerospace 146 Service Bulletin 25-294- 36108B. Compliance with this directive is critical, and any necessary actions must be completed prior to 6 June 1992. Entities governed by this regulation, such as aircraft operators and maintenance providers, must ensure that the specified modifications to the 2L Call Panel Mountings are carried out. These modifications are necessary to address identified issues with the current cabin interior material flammability, which fails to meet the required safety standards. The operators and maintenance providers must rigorously follow the instructions provided in the British Aerospace Service Bulletin to achieve compliance. Failure to adhere to these standards can result in the aircraft being deemed non-airworthy, leading to potential grounding and significant operational disruptions. In terms of consequences, non-compliance with the provisions of AD/BAe 146/41 can result in severe penalties. The Civil Aviation Safety Authority (CASA) can impose administrative penalties, which may include fines, and in severe cases, criminal charges may be filed against responsible individuals. The exact penalties can vary depending on the severity and circumstances of the non-compliance, but it is clear that the regulatory body takes such matters seriously to ensure the highest standards of aviation safety are maintained. The seriousness of the potential consequences underscores the importance of timely and accurate compliance with the directive.
