AD/INST/18 - Collins PN-101 Pictorial Navigation System Slaving Accessory 328A-3G - Modification

Overview

The Civil Aviation Regulations 1998, as amended, includes specific directives for maintaining the airworthiness of aircraft, and among these is the regulation concerning the Collins PN-101 Pictorial Navigation System, specifically addressing the Slaving Accessory 328A-3G. This legislative instrument, AD/INST/18, was introduced to ensure the safety and reliability of aircraft navigation systems by mandating modifications to the Slaving Accessory type 328A3G with serial numbers ranging from 1500 to 4034. This directive is crucial in addressing potential safety issues related to these specific components, ensuring compliance with airworthiness standards. The regulations are enforced by the Civil Aviation Safety Authority, an entity established under the Civil Aviation Act 1988, with the overarching policy objective of ensuring the safety and efficiency of civil aviation within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 107, issued by the Civil Aviation Safety Authority under the legislative instrument F2006B10819, governs the application of airworthiness directives for particular aviation components, such as the Collins PN-101 Pictorial Navigation System and its slaving accessory type 328A-3G with serial numbers ranging from 1500 to 4034. This regulation applies to the entities and individuals who own, operate, or maintain aircraft equipped with the specified Collins navigation system components. The geographic scope of this regulation is national, as it pertains to the entirety of Australian airspace and any Australian-registered aircraft regardless of their location. The regulation mandates compliance with the modifications specified in Collins SB No. 14 before a particular date, 28 February 1976, to ensure the continued airworthiness and safety of the aircraft involved. Subordinate instruments may extend or further specify the application of these regulations, thereby providing more detailed guidance on compliance and enforcement.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 107, includes provisions under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, with AD/INST/18 focusing on the Collins PN-101 Pictorial Navigation System. This regulation mandates modifications to the Slaving Accessory 328A-3G, applicable to systems with serial numbers ranging from 1500 to 4034. Compliance with these directives necessitates adherence to Collins Service Bulletin No. 14, which must be completed before 28 February 1976. Essentially, these provisions ensure that the specified navigation systems meet necessary safety standards. In terms of obligations, the regulation requires that the Slaving Accessory 328A-3G be modified in accordance with the guidelines outlined in Collins Service Bulletin No. 14. Operators and owners of aircraft equipped with these navigation systems must ensure that the modifications are carried out before the specified deadline. This involves a detailed inspection and potential overhaul of the affected components to meet the airworthiness standards set by CASA. It is imperative that the modifications are carried out by certified personnel to ensure compliance and maintain the airworthiness of the aircraft. Failure to comply with these airworthiness directives can result in significant consequences. Non-compliance with AD/INST/18 could lead to the aircraft being grounded until the required modifications are completed. Moreover, the regulation may impose penalties for non-compliance, although specific penalties are not detailed in the provided excerpt. In general, CASA has the authority to enforce compliance through various measures, including fines or other legal actions. The overarching intent is to maintain the highest safety standards in civil aviation, ensuring that any potential hazards are mitigated through timely and appropriate modifications.
