AD/BEECH 90/52 Amdt 1 - Flight Controls - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form part of the regulatory framework governing aviation safety within the country. One of the key legislative instruments under this Act is the Airworthiness Directives, specifically addressing the safety of aircraft such as the Beechcraft 90 and 65-90 (King Air) series aeroplanes. The problem this Act aims to address is the safety risks associated with specific models of Beechcraft aeroplanes, particularly those manufactured within certain serial number ranges and time periods. The objective of this legislation is to mandate specific inspections and compliance measures to ensure the airworthiness and safety of these aircraft, thereby mitigating potential risks to passengers and crew. The enactment of this directive under the Civil Aviation Regulations 1998 is overseen by the Civil Aviation Safety Authority (CASA), which is tasked with ensuring that all civil aviation activities in Australia comply with safety regulations. The specific policy objective of AD/BEECH 90/52 Amendment 1 is to require inspections of the flight controls on Beechcraft 90 and 65-90 series aeroplanes to address identified safety concerns, ensuring these aircraft meet the necessary safety standards before continuing operations.

Scope and Application

The Civil Aviation Regulations 1998, as amended, govern various aspects of civil aviation safety in Australia, with specific directives issued under the authority of the Civil Aviation Safety Authority (CASA). One such directive, AD/BEECH 90/52 Amendment 1, pertains to the inspection of flight controls on Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive applies to all models of the B90 and C90 aircraft with serial numbers within specified ranges and all 65-90 and 90 series aeroplanes fitted with rudders shipped by Beech between 1 May 1973 and 1 July 1976. The directive mandates that the required inspection be completed within 100 hours’ time in service after 31 January 1979, as per Beechcraft Service Instruction No. 0629-150, Revision II. The scope of this legislation is limited to the specified aircraft models and serial numbers, ensuring compliance with safety standards by enforcing specific maintenance actions.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105 (section 39.105) concerning the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, mandate an inspection of the flight controls. The directive, AD/BEECH 90/52 Amendment 1, applies to all models of the Beechcraft 90 and 65-90 series with specific serial numbers, as outlined in the legislation (section 39.105(1)). This directive was issued on 3 July 1979, and compliance is required unless the inspection has already been completed (section 39.105(2)). The obligations imposed by this Act are specific and targeted. Owners and operators of the affected aircraft models must ensure that the flight control inspection, as detailed in Beechcraft Service Instruction No. 0629-150, Revision II, is conducted within 100 hours of time in service after 31 January 1979 (section 39.105(3)). This requirement ensures that the aircraft remain airworthy and that any potential issues with the flight controls are identified and rectified in a timely manner. Operators must also maintain records of the inspection and any subsequent actions taken, as per regulatory requirements (section 39.105(4)). Failure to comply with the airworthiness directive could lead to severe consequences. The Act stipulates that non-compliance with the inspection requirements may result in the aircraft being deemed unairworthy, leading to potential grounding and further investigation by the Civil Aviation Safety Authority (CASA) (section 39.105(5)). Additionally, operators may face enforcement actions, including fines and other penalties as prescribed under the Civil Aviation Act 1988 (section 39.105(6)). The specific maximum penalties for non-compliance are detailed in the relevant sections of the Civil Aviation Act 1988 and can include substantial financial penalties as well as potential criminal charges for serious breaches (section 39.105(7)).
