AD/DH114/12 Amdt 1 - Aileron Lever Part No. 14 WA. 199 - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, as amended, encompass a comprehensive regulatory framework governing civil aviation safety in Australia. One particular legislative instrument, F2006B08922, addresses the specific issue of airworthiness directives for the DH114 (Heron) series aeroplanes. Enacted by the Australian Government, this regulation was introduced to ensure the ongoing safety and compliance of these aircraft in accordance with civil aviation standards. The primary objective of this legislative instrument is to mandate inspections and modifications to the aileron lever part, ensuring the aircraft remains airworthy and safe for operation. The Civil Aviation Safety Authority (CASA) oversees the enforcement of these regulations, ensuring that all applicable aircraft meet the required safety standards and are maintained to prevent any potential risks to flight safety.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under the jurisdiction of the Commonwealth of Australia, apply to all individuals and entities operating aircraft within Australia, including private and commercial entities, as well as any aircraft registered in Australia, regardless of where they are based. Specifically, Part 39 - 105, which pertains to the Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the mandatory compliance of aircraft operators with safety directives. This particular directive, AD/DH114/12 Amendment 1, mandates that all models of the DH114 (Heron) Series Aeroplanes, except those incorporating Modification No. 662, must undergo an inspection of the aileron lever part number 14 WA. 199 at intervals not exceeding 50 hours of time in service until modifications are made, with the modification deadline set before 1 June 1970. The directive applies nationally, ensuring uniformity in safety compliance across the Commonwealth, and does not specify any exclusions or exemptions in the provided text. The scope of the directive is further refined or extended through subordinate instruments as necessary to maintain safety standards.

Key Provisions

The Civil Aviation Regulations 1998, under PART 39 - 105, include a specific schedule of airworthiness directives for the DH114 (Heron) Series Aeroplanes, notably AD/DH114/12 Amendment 1, which pertains to the aileron lever part number 14 WA. 199. This directive applies to all models of the Heron series that do not incorporate modification number 662. The Hawker Siddeley TNS Heron (114) No. W.3, Issue 3 document serves as the reference for compliance with these regulations. These provisions require the inspection of the aileron lever at intervals not exceeding 50 hours of time in service, continuing until the modification is made. Moreover, the directive mandates that the modification must be completed before 1 June 1970. The directive is designed to ensure the continued safety and airworthiness of the aircraft by addressing potential issues with the aileron lever. The Civil Aviation Regulations impose specific obligations on the operators and maintainers of the DH114 (Heron) Series Aeroplanes. Operators must adhere to the inspection intervals and ensure that any identified issues are rectified promptly. Maintainers, on the other hand, are responsible for conducting the required inspections and making the necessary modifications to the aileron lever to meet the regulatory standards. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, leading to potential grounding and severe operational disruptions. Breach of the provisions outlined in the Civil Aviation Regulations can lead to significant consequences. While the specific civil or criminal penalties are not detailed in the legislative instrument, non-compliance generally results in enforcement actions by the Civil Aviation Safety Authority (CASA). These actions can include fines, suspension of airworthiness certificates, or other regulatory sanctions. The severity of these consequences underscores the importance of adhering to the prescribed inspection and modification requirements to maintain the safety and regulatory compliance of the aircraft.
