AD/ELECT/18 Amdt 3 - Slick 4000/4100 Series Sealed Non-Repairable Magnetos - Retirement Life

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B09407, was enacted to ensure the safety and reliability of aviation equipment. Specifically, Part 39 - 107, concerning the Civil Aviation Safety Authority's schedule of airworthiness directives, was developed to address gaps in the safe operation of aircraft by mandating specific actions for the maintenance and retirement of certain components. The legislation was introduced by the Australian Parliament to uphold stringent safety standards and reduce the risk of accidents caused by equipment failure. The policy objective of this regulation is to enhance the overall safety of civil aviation by ensuring that electrical equipment, particularly Slick 4000/4100 series sealed non-repairable magnetos, are retired from service at the appropriate times to prevent their operation beyond their designed lifespan.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 107, addresses the requirements for the airworthiness of electrical equipment, with AD/ELECT/18 Amendment 3 focusing on the Slick 4000/4100 series sealed non-repairable magnetos. This directive applies to all Slick 4000/4100 series sealed non-repairable magnetos, excluding the newer Slick 4200 series which can be overhauled. The requirement outlined in this amendment is to retire these specific magnetos from service to ensure safety and compliance with airworthiness standards. The directive stipulates that magnetos with more than 700 hours of total time in service must be retired within 100 hours of time in service after 18 April 1991, while those with less than 700 hours total time in service must be retired before exceeding 800 hours total time in service. This regulation extends to all relevant entities and persons operating within the Commonwealth of Australia, ensuring adherence to civil aviation safety standards across the industry.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (Cth) under the Airworthiness Directive AD/ELECT/18 Amendment 3, specifically addressing Slick 4000/4100 series sealed non-repairable magnetos, are primarily concerned with the retirement of these components from service. Section 107 mandates the retirement of these magnetos from service to ensure they do not exceed their designed life, which could lead to potential safety risks. The directive applies to all Slick 4000/4100 series sealed non-repairable magnetos but explicitly excludes the new Slick 4200 series, which can be overhauled. The directive outlines specific timelines for the retirement of these magnetos, depending on their total time in service as of 18 April 1991. For magnetos with more than 700 hours of total time in service, retirement must occur within 100 hours after 18 April 1991. For those with less than 700 hours, retirement must occur before the magnetos exceed 800 hours of total time in service. The obligations imposed by this directive are clear and specific. Operators of aircraft equipped with Slick 4000/4100 series sealed non-repairable magnetos must monitor the total time in service of these components and ensure they are retired in accordance with the specified timelines. This includes keeping detailed records of the total time in service of each magneto and planning for the replacement or retirement of the components well before they reach the critical thresholds. Additionally, operators must ensure that any personnel involved in the maintenance and operation of these aircraft are aware of and understand the requirements of this directive to avoid any inadvertent breaches. Failure to comply with the requirements of this directive can result in serious consequences. Civil Aviation Safety Authority regulations do not explicitly state penalties for non-compliance with this specific directive within the provided text, but non-compliance with Civil Aviation Regulations generally can lead to enforcement actions. These actions may include fines, suspension or revocation of an operator’s certificate, and potential criminal charges if the non-compliance results in an incident or accident. Such enforcement actions are designed to ensure that all parties adhere to the safety standards mandated by the regulations, thereby maintaining the high safety standards expected in the aviation industry.
