AD/HU 269/59 - Cockpit Placard - Removal

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form a comprehensive regulatory framework governing civil aviation safety across the nation. One part of this legislative instrument is the Schedule of Airworthiness Directives, which includes specific directives aimed at ensuring that aircraft meet the required safety standards. The directive AD/HU 269/59 concerning Schweizer (Hughes) 269 Series Helicopters is one such measure. It was introduced to address safety concerns related to the operation of these helicopters, particularly focusing on the modification of cockpit placards. The policy objective behind this directive is to ensure that pilots are not misled by outdated or incorrect information on the instrument panel, thereby enhancing flight safety and reducing the risk of accidents due to operational errors. The directive mandates that the specific limitation regarding engine RPM below a certain altitude be blanked out or removed from the aircraft's instrument panel within 100 hours after a specified date to ensure compliance with current safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, address the requirements for airworthiness directives pertinent to Schweizer (Hughes) 269 Series Helicopters, as outlined in AD/HU 269/59. This legislation applies to all 269C models, focusing on the modification of cockpit placards to enhance safety. The requirement pertains to the blanking out or removal of the specified limitation, "3200 RPM Minimum below 400 feet above terrain," which is found on the instrument panel at the bottom of the manifold pressure placard. The compliance mandate stipulates that this modification must be completed within 100 hours of time in service following 31 July 1977. This directive is instrumental in ensuring the operational safety of these aircraft and is a critical aspect of maintaining airworthiness standards. The application of this legislation is jurisdictional and enforced by the Civil Aviation Safety Authority (CASA) across the Commonwealth of Australia, underscoring its importance in the national aviation sector.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, includes specific Airworthiness Directives (AD) aimed at ensuring the safety and airworthiness of aircraft. One such directive is AD/HU 269/59, which pertains to Schweizer (Hughes) 269 Series Helicopters (section 105). This directive mandates the removal or blanking out of a specific limitation placard from the cockpit instrument panel. Specifically, the requirement is to eliminate the limitation "3200 RPM Minimum below 400 feet above terrain" found on the manifold pressure placard. This directive is applicable to all 269C Models of the Schweizer (Hughes) 269 Series Helicopters. The primary obligation imposed by this directive is that the limitation placard must be removed or blanked out within 100 hours of the helicopter’s time in service after 31 July 1977. This requirement ensures that pilots are not constrained by this particular limitation, which could potentially impact flight safety and operational efficiency. Compliance with this directive is necessary to maintain the aircraft's airworthiness and adherence to safety standards set by the Civil Aviation Safety Authority (CASA). Failure to comply with AD/HU 269/59 can lead to various consequences. While the specific penalties are not detailed in the directive itself, non-compliance with airworthiness directives typically results in significant penalties under the Civil Aviation Act 1988. These penalties can include substantial fines, enforcement actions, and potential grounding of the aircraft until the directive is complied with. Moreover, non-compliance can also lead to criminal charges for those responsible, particularly if it is found that the non-compliance contributed to an aviation incident or accident. The potential penalties underscore the importance of adhering to these directives to ensure the safety and regulatory compliance of the aircraft.
