AD/BEECH 23/10 - Wing Spar Lower Boom

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation in Australia. Among the numerous directives, Part 39 - 105 includes Airworthiness Directives (ADs) for specific aircraft models, such as the Beechcraft 19, 23, and 24 series aeroplanes. The AD/BEECH 23/10 specifically addresses the wing spar lower boom for all models with Hawker de Havilland Kit No. 05-F-63 incorporated. This directive mandates compliance with Hawker de Havilland Technical Notice Service (TNS) Beech-Aus No. 5, requiring inspections and actions to be performed at 2500 hours total time in service and subsequently at intervals not exceeding 500 hours time in service after 1 September 1971. The underlying policy objective is to maintain the airworthiness of these aircraft, ensuring ongoing safety and reliability in Australian airspace.

Scope and Application

The Civil Aviation Regulations 1998, under the scope of the Civil Aviation Safety Authority (CASA) and specifically within Part 39 - 105, address the airworthiness directives for certain aircraft models. This legislative instrument pertains to Beechcraft 19, 23 and 24 Series aeroplanes, focusing on the wing spar lower boom for models that incorporate Hawker de Havilland Kit No. 05-F-63. The requirement necessitates compliance with Hawker de Havilland Technical Notice Service (TNS) Beech-Aus No. 5. This directive mandates that specific actions be taken at 2500 hours of total time in service and subsequently at intervals not exceeding 500 hours of time in service, with effect from 1 September 1971. The legislation is designed to ensure the continued airworthiness and safety of these aircraft, applying to any person or entity operating such aircraft within Australia. The regulations are enforced by CASA, ensuring adherence to the specified maintenance and inspection intervals to uphold safety standards in civil aviation.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically addresses the airworthiness of certain aircraft types, including the Beechcraft 19, 23, and 24 series aeroplanes. One of the key provisions is AD/BEECH 23/10, which pertains to the wing spar lower boom (section 39-105). This directive applies to all models with Hawker de Havilland Kit No. 05-F-63 incorporated. The requirement is for action to be taken in accordance with Hawker de Havilland Technical Notice Service (TNS) Beech-Aus No. 5. This action must be implemented at 2500 hours of total time in service and subsequently at intervals not exceeding 500 hours of time in service after 1 September 1971. The obligations imposed by this regulation are specific to aircraft operators and owners of the affected Beechcraft models. They must ensure that the prescribed action outlined in TNS Beech-Aus No. 5 is undertaken. This involves regular inspections and maintenance of the wing spar lower boom to ensure it remains within the specified safety parameters. The compliance schedule necessitates checks at critical time intervals to maintain the aircraft's airworthiness. Failure to adhere to these intervals or to carry out the required actions could result in the aircraft being deemed unairworthy. In terms of consequences for non-compliance, the Civil Aviation Regulations 1998 provide for both civil and criminal penalties. Civil penalties can include fines and enforcement actions, while criminal penalties may be imposed in more severe cases. The exact penalties are not detailed in the provided text, but they can be significant, reflecting the importance of adhering to airworthiness directives to ensure public safety. It is crucial for operators and owners to be aware of these obligations and to maintain meticulous records of compliance to avoid potential legal repercussions.
