AD/DH 104/13 - Crossed Aileron Control Cables - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as a comprehensive set of rules governing civil aviation within Australia. One of the legislative instruments, F2006B08857, pertains to Part 39 - 105 of these regulations, specifically focusing on civil aviation safety authority schedules of airworthiness directives for De Havilland 104 (Dove) series aeroplanes. This legislative instrument was introduced to address safety concerns related to crossed aileron control cables, aiming to ensure the airworthiness of these aircraft by mandating regular inspections. The policy objective is to enhance safety by preventing potential mechanical failures that could compromise the control of the aircraft. The Civil Aviation Safety Authority is the enacting body responsible for implementing these directives to maintain high safety standards in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority Schedule of Airworthiness Directives for de Havilland DH 104 (Dove) Series Aeroplanes, applies to all models of this aircraft type. This regulation is pertinent to aviation entities, including operators, maintenance providers, and aircraft owners, requiring them to comply with the stipulations outlined in the document De Havilland TNS CT(104) No. 171. The geographic reach of this regulation is nationwide, ensuring uniform safety standards across the Commonwealth of Australia. Compliance with this directive mandates a thorough inspection of crossed aileron control cables on each occasion when the aileron control circuit is disturbed. This regulation does not specify exclusions or exemptions but rather necessitates strict adherence to the prescribed procedures to maintain airworthiness and ensure the safety of the aircraft operations. The scope of this directive is extended and clarified through subordinate instruments and detailed documentation, providing comprehensive guidance to ensure consistent and effective application.

Key Provisions

The Civil Aviation Regulations 1998, particularly in Part 39, outline several key sections that govern the airworthiness of aircraft. Section 39-105 specifically pertains to the Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). Under this section, AD/DH 104/13 addresses the inspection of crossed aileron control cables for De Havilland 104 (Dove) Series aeroplanes (Section 39-105(1)). The directive mandates that all models of the Dove series must adhere to the specified inspection requirements to ensure the integrity of the aileron control circuit. Entities governed by these regulations, such as aircraft operators and maintenance providers, are required to comply with AD/DH 104/13 (Section 39-105(2)). This involves performing an inspection of the aileron control cables each time the aileron control circuit is disturbed, as stipulated in the De Havilland Technical Notice TNS CT(104) No. 171 (Section 39-105(3)). Failure to conduct these inspections could compromise the safety of the aircraft, leading to potential non-compliance with airworthiness standards. The Civil Aviation Regulations 1998 impose significant obligations on those responsible for the maintenance and operation of the De Havilland 104 Series aeroplanes. These obligations include conducting mandatory inspections of the aileron control cables and ensuring all maintenance actions are documented and performed in accordance with the technical notices provided by the manufacturer (Section 39-105(4)). Non-compliance with these directives may result in severe consequences, including the grounding of the aircraft until the required inspections and repairs are completed. Additionally, operators and maintenance personnel must be adequately trained and certified to perform these inspections, as specified by CASA. Failure to adhere to the requirements set forth in AD/DH 104/13 can result in serious legal and financial repercussions. The regulations stipulate that any breach of these airworthiness directives may lead to enforcement actions by CASA, which can include fines and penalties (Section 39-105(5)). The maximum penalties for non-compliance can be substantial, reflecting the critical nature of maintaining airworthiness in aviation. Civil penalties may be imposed for each occurrence of non-compliance, while criminal penalties may apply in cases of gross negligence or willful disregard of the regulations. It is imperative for all stakeholders to understand and comply with these directives to ensure the safety and airworthiness of the De Havilland 104 Series aeroplanes.
