AD/RES/22 Amdt 1 - Pacific Scientific Buckle - Agricultural Aircraft

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, were enacted to ensure the safety of aviation operations within Australia. The legislation is overseen by the Parliament of Australia and aims to provide a comprehensive regulatory framework to maintain high safety standards in civil aviation. One of the specific amendments to these regulations is the Airworthiness Directive (AD) concerning restraint equipment used in agricultural aircraft, particularly focusing on the Pacific Scientific buckle. This amendment was introduced to address safety concerns identified in the aftermath of an accident where the buckle's retaining toggles were found to be inadequate under certain stress conditions. The policy objective of AD/RES/22 Amendment 1 is to mandate the removal or replacement of specified buckles to prevent similar incidents, ensuring that all safety harnesses meet the necessary safety standards before 31 December 1989.

Scope and Application

The AD/RES/22 Amendment 1 under the Civil Aviation Regulations 1998 applies to all safety harnesses used in agricultural aircraft, focusing specifically on the Pacific Scientific buckle part number 1101550 with all dash numbers. This regulation mandates the inspection of all affected buckles and their removal from service if they match the specified part number. Compliance is required before 31 December 1989, with the option to either replace the entire harness with an approved one that does not use the specified buckle or replace the buckle itself with an approved alternative. The directive falls under the purview of the Civil Aviation Safety Authority, reflecting its jurisdiction over aviation safety in Australia. The regulation does not specify exclusions or exemptions, implying that all agricultural aircraft utilising the identified buckles must adhere to the stipulated requirements. Subordinate instruments may further detail compliance procedures and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 107, mandates the applicability of airworthiness directives concerning restraint equipment in agricultural aircraft. Notably, AD/RES/22 Amendment 1 pertains to the Pacific Scientific Buckle, part number 1101550, which is used in all safety harnesses in agricultural aircraft (section 1). The primary requirement of this directive is twofold: first, an inspection must be conducted to ascertain whether the specified Pacific Scientific buckle is in use, and second, if it is found, it must be removed from service (section 2). The removal can be accomplished by either replacing the entire harness with an approved one that does not use this buckle or by replacing the buckle with a different, approved type that is suitable for the harness (section 2(a) and (b)). The compliance deadline for these actions is set before 31 December 1989 (section Compliance). This directive was prompted by an accident investigation that identified potential safety issues with the buckle's retaining toggles, which might not meet the required 25g capability due to material inadequacies. Amendment 1 serves to clarify the part number applicability, ensuring that the correct buckles are identified and replaced. Under the Civil Aviation Regulations 1998, entities such as aircraft operators and maintenance providers are obligated to adhere to the airworthiness directive AD/RES/22 Amendment 1. They must ensure that all safety harnesses used in agricultural aircraft are inspected to identify the presence of the Pacific Scientific buckle, part number 1101550. If this buckle is found, operators must take immediate action to replace it either by using an entirely new harness that is compliant with safety standards or by replacing the buckle with an approved alternative. This requirement extends to ensuring that all such changes are completed before the specified compliance deadline of 31 December 1989. The obligation also includes maintaining records of the inspections and any actions taken to ensure compliance with the directive. Failure to comply with the provisions of AD/RES/22 Amendment 1 could result in significant legal and operational consequences. The Civil Aviation Regulations 1998, although the specific penalties are not detailed in the legislative instrument provided, typically outline potential civil or criminal penalties for non-compliance with airworthiness directives. Such penalties could include fines, suspension or revocation of operating certificates, or other regulatory sanctions. These measures are intended to ensure the highest standards of safety in civil aviation, particularly in the context of agricultural aircraft where safety harness integrity is critical. Non-compliance could potentially lead to severe accidents, thus making adherence to these directives imperative.
