AD/HU 269/58 Linear Clutch Actuator End Fitting and Shaft - Inspection
6/77
Applicability: All models with Linear clutch actuators P/N 269A4564 or DL 1020M82C (24V) or DL 1020M48 or DL 1020M81C (12V) NOTE: Helicopters fitted with the 269A4564- 5 (24V clutch actuators assembly are not affected.
Document: Hughes SIN No. N-141.1. (FAA AD 77-07-01) refers.
Compliance: For Part II. At each daily inspection after 30 June 1977, until modified in accordance with Part I.
For Part III. Within 100 hours time in service after 30 June 1977 and thereafter at intervals not exceeding 100 hours time in service, until modified in accordance with Part I.
Note: The inspection detailed in Part II of this requirement document shall be entered on the maintenance release as maintenance required. That inspection may be performed by the pilot in command, in which case certification is not required. In all other cases certification may be made on the maintenance release. That inspection may also be performed and certified by any Licensed Aircraft Maintenance Engineer.
Overview
The Civil Aviation Regulations 1998 were enacted to provide comprehensive regulations for civil aviation in Australia, ensuring safety and efficiency in the industry. One specific legislative instrument under this act is the AD/HU 269/58, which pertains to the Schweizer (Hughes) 269 Series Helicopters. This directive was introduced to address safety concerns associated with the Linear Clutch Actuator End Fitting and Shaft, ensuring these components are regularly inspected and maintained. The problem it was introduced to address is the potential for failure in the Linear Clutch Actuator End Fitting and Shaft, which could lead to significant safety risks in aviation operations. The enactment of this directive by the Civil Aviation Safety Authority is aimed at ensuring compliance with safety standards, thereby safeguarding the well-being of passengers and crew. The policy objective is to mitigate the risk of mechanical failure through regular inspections and appropriate modifications as necessary.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) and mandates compliance with certain safety standards for specified aircraft models. In this instance, AD/HU 269/58 is focused on Schweizer (Hughes) 269 Series helicopters. The regulation applies to all models equipped with specific Linear clutch actuators P/N 269A4564 or DL 1020M82C (24V) or DL 1020M48 or DL 1020M81C (12V), excluding those with the 269A4564- 5 (24V clutch actuators assembly. The geographic and jurisdictional reach of these regulations is national, applying across all states and territories within the Commonwealth of Australia. The directive extends to all operators of these helicopter models, requiring adherence to the inspection and maintenance protocols outlined within the regulation. Compliance is mandatory, with inspections required at specified intervals and daily, depending on the part of the directive being referenced. Exemptions or exclusions are narrowly defined, focusing on specific components and assemblies within the helicopter models. The regulation may be further extended or restricted through subordinate instruments, ensuring that the safety standards are consistently applied and updated as necessary.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, address the airworthiness directives concerning Schweizer (Hughes) 269 Series Helicopters, with particular focus on the Linear Clutch Actuator End Fitting and Shaft as outlined in AD/HU 269/58 (6/77). This legislative instrument mandates that all models equipped with specific Linear clutch actuators must adhere to stringent inspection requirements. These actuators include P/N 269A4564 or DL 1020M82C (24V), DL 1020M48, or DL 1020M81C (12V), with the exception of those fitted with the 269A4564-5 (24V clutch actuators assembly, which are not subject to this directive.
The obligations imposed by this legislation are twofold. Firstly, for Part II, daily inspections must be conducted post 30 June 1977 until the helicopters are modified as per Part I of the directive. Secondly, for Part III, inspections are required within 100 hours of time in service after 30 June 1977, and then at intervals not exceeding 100 hours until modification. The inspections specified in Part II of the requirement document must be recorded in the maintenance release as maintenance required. Importantly, these inspections can be performed by the pilot in command, though certification is not mandatory in such cases. Otherwise, certification by a licensed aircraft maintenance engineer is required, with the exception that inspections performed by the pilot in command need not be certified.
Failure to comply with these directives can result in significant legal consequences. The regulations establish civil and criminal penalties for non-compliance. Although the specific penalties are not detailed within the provided text, it is understood that non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority, which may include fines, operational restrictions, and potentially criminal charges for serious breaches. The severity of the penalties may depend on the nature and extent of the non-compliance, as well as any resultant safety implications.
