AD/BEECH 77/15 Amdt 1 - Alternator System

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to provide a comprehensive legal framework governing all aspects of civil aviation in Australia, aiming to ensure the safety and efficiency of air travel. The specific amendments under Part 39 - 105, such as AD/BEECH 77/15 Amendment 1, address safety concerns identified in particular aircraft models, in this case, the Beechcraft 77 (Skipper) Series Aeroplanes. The objective of these directives is to mandate corrective actions to prevent potential hazards, such as the overheating of the reverse current diode in the alternator system, which has led to incidents of smoke in the cockpit. These amendments are issued by the Civil Aviation Safety Authority and require compliance within a specified timeframe to mitigate identified risks.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, apply to Beechcraft 77 (Skipper) Series Aeroplanes, namely those with serial numbers WA-1 through WA-312. This legislation mandates compliance with Beechcraft Service Bulletin 2201, Revision 1, to address the issue of the reverse current diode overheating and generating smoke in the cockpit. The requirement is that the specified action must be undertaken within 100 hours’ time in service after the directive was issued on 19 May 1988, or at the next scheduled inspection for Maintenance Release issue, whichever comes first. The regulation's jurisdictional reach is national, governed by the Commonwealth of Australia, and it applies to the specified aircraft within the defined serial number range. There are no stated exclusions, exemptions, or thresholds in this directive. Subordinate instruments may extend or further detail the application of these regulations, ensuring comprehensive adherence to the prescribed safety measures.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, Section 105, address the safety of the Beechcraft 77 (Skipper) Series Aeroplanes through Airworthiness Directives (AD). These directives are designed to ensure that specific aircraft models meet safety standards set by the Civil Aviation Safety Authority (CASA). AD/BEECH 77/15 Amendment 1 focuses on the alternator system of the Beechcraft Skipper 77, serial numbers WA-1 through WA-312. The directive requires that aircraft owners and operators comply with Beechcraft Service Bulletin 2201, Revision 1, to rectify issues related to the reverse current diode overheating and causing smoke in the cockpit (Section 105.01(1)). Compliance with AD/BEECH 77/15 Amendment 1 is mandatory and must be achieved within 100 hours of the aircraft's time in service after 19 May 1988, or at the next scheduled inspection for Maintenance Release, whichever occurs first (Section 105.01(2)). This directive imposes an obligation on the owners and operators of the specified Beechcraft Skipper 77 aircraft to take immediate corrective action as outlined in the referenced service bulletin. Failure to comply with these requirements may result in the aircraft being deemed unairworthy, leading to grounding and potential refusal of maintenance release. In the event of non-compliance with the AD/BEECH 77/15 Amendment 1, there are potential civil and criminal consequences. The maximum penalties for breaches of the Civil Aviation Regulations can include fines and imprisonment. Specifically, under Section 105.05, non-compliance with ADs can result in fines of up to $50,400 for individuals and $252,000 for corporations, as well as imprisonment for up to two years. Additionally, CASA has the authority to issue enforcement actions, including the suspension or revocation of airworthiness certificates, further compounding the penalties for non-compliance.
