AD/HU 269/37 - Main Rotor Lead - Lag and Flapping Hinge Bolts P/N HS1446-10-68 Vendo Identification (BM) - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, represent a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia. One pertinent legislative instrument under this act is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/HU 269/37, which targets Schweizer (Hughes) 269 Series Helicopters. This directive was introduced to address the issue of ensuring the continued airworthiness of older helicopter models by mandating regular inspections of critical components such as the main rotor lead-lag and flapping hinge bolts. The policy objective is to mitigate risks associated with potential mechanical failures that could compromise flight safety. By requiring specific inspection protocols for identified models, the regulation aims to maintain high safety standards and protect both crew and passengers.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, addresses the Australian Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives concerning Schweizer (Hughes) 269 Series Helicopters, which includes models 269A, 269A-1, 269B, and 269C delivered prior to 1 August 1970. The legislation applies to these helicopter models to ensure compliance with safety directives related to the main rotor lead-lag and flapping hinge bolts P/N HS1446-10-68 Vendo Identification (BM) inspection. The directive mandates adherence to specified requirements outlined in documents Hughes SIN No. N-78 or FAA AD 70-17-3. The applicability of these regulations is enforced under the Commonwealth of Australia, thus extending across the national jurisdiction. The legislation does not explicitly mention exclusions, exemptions, or thresholds within the provided text, and any further details on these aspects would likely be found in subordinate instruments or additional regulatory documents issued by CASA.

Key Provisions

The main operative sections of this legislative instrument (F2006B10604) pertain to specific safety directives for Schweizer (Hughes) 269 Series Helicopters, particularly regarding the inspection of main rotor lead-lag and flapping hinge bolts. According to Section 105 of the Civil Aviation Regulations 1998, these provisions apply to Schweizer (Hughes) 269A, 269A-1, 269B, and 269C models that were delivered prior to 1 August 1970. The requirement is to inspect the main rotor lead-lag and flapping hinge bolts with part number HS1446-10-68, identified by Vendo (BM). Compliance with these directives must be carried out in accordance with the specified requirement documents, namely Hughes SIN No. N-78 or FAA AD 70-17-3. The obligations imposed by this Act on the parties or entities it governs are quite specific. Operators of the Schweizer (Hughes) 269 Series Helicopters mentioned must ensure that the prescribed inspections are performed on the main rotor lead-lag and flapping hinge bolts. This includes verifying that the bolts are inspected according to the outlined requirement documents. The intent behind these directives is to ensure the airworthiness of the aircraft by maintaining the integrity of the main rotor system, which is critical for the safety of the helicopter and its occupants. Failure to comply with the airworthiness directives could result in significant legal consequences. The Act does not explicitly state the penalties or consequences for non-compliance, but under the broader framework of the Civil Aviation Act 1988 and associated regulations, violations of airworthiness directives can lead to enforcement actions. These can include fines, suspension or revocation of airworthiness certificates, and potentially criminal charges if the non-compliance results in an accident or serious safety incident. The exact penalties would depend on the severity of the breach and the specific circumstances surrounding it, but they can be substantial. In summary, the Civil Aviation Regulations 1998, through this legislative instrument, mandate specific inspections on certain Schweizer (Hughes) 269 Series Helicopters to ensure the safety and airworthiness of these aircraft. Non-compliance with these directives can lead to severe penalties, including administrative, financial, and potentially criminal repercussions. Operators must adhere to the specified requirement documents to avoid these consequences and ensure the safety of their operations.
