AD/HS 125/27 Amdt 1 - Flexible Hydraulic Hose - Inspection

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation in Australia. One of the specific amendments within these regulations is AD/HS 125/27 Amendment 1, concerning the inspection of flexible hydraulic hoses on British Aerospace BAe 125 Series aeroplanes. This amendment was introduced to address the potential safety risks associated with hydraulic hose failures, which could lead to catastrophic failures in flight. The policy objective is to mitigate risks by mandating regular inspections and maintenance of these critical components. However, this particular directive has been removed from the listing as the specified aircraft model is no longer registered in Australia.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically within Part 39 - 105, governs the airworthiness directives that apply to civil aviation operations within Australia. This legislation applies to all individuals and entities involved in the operation of civil aircraft, including but not limited to aircraft manufacturers, operators, and maintenance service providers. It mandates compliance with specific airworthiness directives aimed at ensuring the safety and reliability of aircraft. The directive concerning the British Aerospace BAe 125 Series Aeroplanes, such as AD/HS 125/27 Amendment 1, which focuses on the inspection of flexible hydraulic hoses, applies nationally across all states and territories of Australia. The application of these regulations is subject to exclusions and thresholds as outlined within the subordinate instruments and specific airworthiness directives. Notably, this particular directive has been removed from the listing as the referenced aircraft model is no longer on the register.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, includes specific provisions for the airworthiness of aircraft, such as the British Aerospace BAe 125 Series Aeroplanes. Section 39.05 (1) requires the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (AD) to ensure the continued safety of aircraft. In this context, AD/HS 125/27 Amendment 1, although currently removed from the listing, would have specified the inspection requirements for the flexible hydraulic hoses on BAe 125 Series Aeroplanes. The directive aims to address potential safety issues by mandating regular checks and maintenance on these critical components. The obligations imposed by such directives include the requirement for aircraft operators to comply with the inspection and maintenance schedules specified in the ADs. Operators must ensure that the aircraft remain in a safe condition for flight by adhering to the prescribed timelines and procedures. This involves scheduling regular inspections, documenting findings, and performing necessary repairs or replacements as directed. The responsibility lies with the operator to maintain accurate records and demonstrate compliance to CASA upon request. Failure to comply with the Airworthiness Directives can result in severe consequences, both civil and criminal. Under the Civil Aviation Act 1988, non-compliance can lead to enforcement actions by CASA, including fines, suspension or revocation of the aircraft's certificate of airworthiness, and potential criminal charges. The maximum penalties for such offences can include substantial fines for corporations, as well as imprisonment for individuals found guilty of deliberately breaching safety regulations. The seriousness of these consequences underscores the importance of strict adherence to the ADs and maintaining the highest safety standards in civil aviation.
