AD/DH114/24 - Nose Undercarriage - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, which were enacted in 1998, aim to ensure the safety and efficiency of civil aviation in Australia. The Regulations are overseen by the Civil Aviation Safety Authority (CASA), which is responsible for enforcing compliance with aviation safety standards and directives. The policy objective of these regulations is to enhance the safety of civil aviation by setting forth stringent standards and directives that must be followed by all relevant entities, including aircraft manufacturers, operators, and maintenance personnel. One specific area addressed by these regulations is the airworthiness of certain aircraft models, including the Heron Series aeroplanes. In this context, Airworthiness Directive AD/DH114/24 pertains to the inspection and modification of the nose undercarriage of all Series 2 Heron aeroplanes, except those that incorporate the Heron Mod. 1093. The directive requires inspections within 100 hours of time in service after 29 May 1970, and subsequent inspections at intervals not exceeding 100 hours until the necessary modifications are made. Furthermore, any required modifications must be completed before 1 August 1970 to ensure continued compliance with safety standards.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 105, specifically address the application of airworthiness directives for certain aircraft, including the DH114 (Heron) Series Aeroplanes. This particular legislation applies to all Series 2 aeroplanes of the Heron model that do not incorporate the Heron Mod. 1093. The regulation mandates a stringent compliance schedule for these aircraft, stipulating that an inspection must be conducted within 100 hours of time in service after 29 May 1970, with subsequent inspections required at intervals not exceeding 100 hours until the specified modifications are made. Furthermore, any necessary modifications must be completed before 1 August 1970. The scope of this regulation is limited to ensuring the continued airworthiness and safety of the specified aircraft, and it is overseen by the Civil Aviation Safety Authority. This legislative instrument ensures that the Heron Series 2 aeroplanes meet critical safety standards, thereby protecting both the aircraft and those on board.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, Section 105, outline the Airworthiness Directives for the DH114 (Heron) Series Aeroplanes. Section AD/DH114/24 focuses on the nose undercarriage, requiring inspections and modifications to ensure safety (AD/DH114/24). This section applies to all Series 2 aeroplanes that do not incorporate the Heron Mod. 1093 (AD/DH114/24). The directive mandates an inspection of the nose undercarriage within 100 hours of time in service following 29 May 1970, and subsequent inspections must occur at intervals not exceeding 100 hours of time in service until the required modifications are made (AD/DH114/24). Modifications must be completed before 1 August 1970 (AD/DH114/24). Under the Civil Aviation Regulations, the obligations imposed by AD/DH114/24 require operators of the DH114 (Heron) Series 2 aeroplanes to ensure that the nose undercarriage is inspected within the specified timeframes and that any necessary modifications are carried out in a timely manner. Operators must maintain detailed records of inspections and modifications, ensuring that all actions comply with the requirements set out in the Airworthiness Directive (AD/DH114/24). Failure to adhere to these obligations could result in the aeroplane being deemed unairworthy, leading to potential grounding and further regulatory action. The Civil Aviation Regulations impose penalties and consequences for non-compliance with AD/DH114/24. If an operator fails to conduct the required inspections or complete the necessary modifications within the stipulated timeframes, they may be subject to enforcement actions. These can include fines, enforcement notices, or other regulatory measures taken by the Civil Aviation Safety Authority. The seriousness of the breach may lead to more severe penalties, potentially impacting the operator's ability to conduct flight operations until compliance is achieved (AD/DH114/24).
