AD/BEECH 90/54 - Aft and Nose Hinged Baggage Door Latching - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, incorporates the Civil Aviation Safety Authority Schedule of Airworthiness Directives, addressing safety concerns for various aircraft models, including the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. Enacted by the Australian Commonwealth Government, these regulations aim to ensure the safety and reliability of civil aviation operations within the country. AD/BEECH 90/54 pertains to the inspection and modification of the aft and nose hinged baggage door latching mechanism, as detailed in Beechcraft Service Instruction No. 1126, to enhance safety by providing a more effective bellcrank stop. This directive applies to specific serial numbers of model C90 and E90 Beechcraft aeroplanes and requires compliance within 100 hours of time in service after 31 July 1980. The policy objective is to mitigate potential safety risks associated with the baggage door latching mechanism, thereby protecting passengers, crew, and the general public.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate the compliance of certain Beechcraft 90 and 65-90 (King Air) series aeroplanes with Airworthiness Directives to ensure safety standards are met. The particular directive AD/BEECH 90/54, dated 7/80, applies to specific model C90 aeroplanes with serial numbers ranging from LJ-569 to LJ-682 and model E90 aeroplanes with serial numbers LW-49, LW-51, LW-64, LW-98, LW-104, LW-122, LW-128, LW-140, and LW-313. The directive focuses on the inspection and modification of the aft and nose hinged baggage door latching mechanisms to provide a more effective bellcrank stop. Compliance with this directive is required within 100 hours of time in service after 31 July 1980. This directive is enforced by the Civil Aviation Safety Authority and applies to aeroplanes operating within Australia’s jurisdiction, ensuring adherence to national civil aviation safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority's schedule of airworthiness directives, includes AD/BEECH 90/54, which addresses the inspection and modification of the aft and nose hinged baggage door latching mechanism for Beechcraft 90 and 65-90 (King Air) Series aeroplanes (Section 1). This directive is applicable to all model C90 with serial numbers LJ-569 to LJ-682 and all model E90 with serial numbers LW-49, LW-51, LW-64, LW-98, LW-104, LW-122, LW-128, LW-140, and LW-313 (Section 2). The directive references Beechcraft Service Instruction No. 1126, which mandates that compliance with the inspection and modification requirements must occur within 100 hours’ time in service after 31 July 1980 (Section 3). The aim of this directive is to enhance the effectiveness of the bellcrank stop for the hinged baggage door latching mechanism, ensuring improved safety and operational integrity of the affected aircraft (Section 4). Under the Civil Aviation Regulations, the entities governed by this directive must ensure that the specified modifications are completed within the stipulated timeframe (Section 5). This involves conducting a thorough inspection of the aft and nose hinged baggage door latching mechanisms, followed by necessary modifications to enhance the bellcrank stop functionality (Section 6). Compliance is not optional; it is mandatory for the specified serial numbers of the Beechcraft 90 and 65-90 (King Air) aeroplanes to meet the safety standards set by the Civil Aviation Safety Authority (Section 7). Failure to comply with these directives can result in significant safety risks and potential operational disruptions. Failure to adhere to the requirements outlined in AD/BEECH 90/54 can lead to serious consequences (Section 8). The Civil Aviation Regulations impose penalties for non-compliance, which can include both civil and criminal ramifications (Section 9). Civil penalties may involve fines, while criminal penalties could lead to imprisonment, reflecting the seriousness of neglecting safety directives (Section 10). The specific maximum penalties are not detailed in the provided text but are typically outlined in related sections of the Civil Aviation Act 1988 or subsequent regulations (Section 11). The overarching aim is to ensure that all aircraft within the specified serial numbers are maintained to the highest safety standards, thereby protecting passengers, crew, and the general public.
