Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, serve as the primary regulatory framework governing civil aviation safety in Australia. Within this extensive legislative instrument, Part 39 outlines specific safety measures, including the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to address identified safety issues. The ADs aim to ensure the continued airworthiness of aircraft by mandating corrective actions in response to specific hazards or unsafe conditions. This regulatory approach is intended to maintain high safety standards in civil aviation, thereby protecting the public and aviation personnel from potential risks. The AD/F100/39, issued in March 2000, is an example of such regulatory measures, specifically targeting the Fokker F100 series aeroplanes to rectify an issue with flight crew shoulder harnesses to prevent their detachment during flight.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, governs the issuance and compliance of Airworthiness Directives (AD) by the Civil Aviation Safety Authority (CASA). These regulations have a wide-reaching application, covering all aircraft operating within Australian airspace, and mandate that any person or entity operating such aircraft must comply with the ADs issued by CASA. This particular AD, AD/F100/39, is targeted at all aircraft equipped with Pacific Scientific Model 0108900 series flight crew shoulder harness assemblies. The directive mandates a one-time inspection and functional check of the shoulder harness in accordance with Fokker Services’ SB F100-25-088, with compliance required before 23 September 2000. The AD came into effect on 23 March 2000, and was issued to address a reported incident where a pilot's shoulder harness pulled out of the inertia reel due to an incorrectly attached reel mechanism. The AD is issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 and is notified in the Commonwealth of Australia Gazette.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, detail mandatory actions for maintaining the airworthiness of Fokker F100 (F28 Mk 100) series aeroplanes. Section 39.1 of the Civil Aviation Regulations 1998 (CAR 1998) authorises the CASA delegate to issue Airworthiness Directives (ADs) to address identified safety issues. The AD/F100/39 issued on 11 February 2000, mandates a one-time inspection and functional check of the flight crew seat shoulder harness assemblies for all Fokker F100 aircraft equipped with Pacific Scientific Model 0108900 series shoulder harness assemblies. This inspection must be carried out in accordance with Fokker Services’ Service Bulletin F100-25-088, and any findings or actions taken should reference the related Regulatory Liaison Document Airworthiness Directive (RLD AD) 1999-139 dated 29 October 1999. The directive was published in the Commonwealth of Australia Gazette on 23 February 2000 and became effective on 23 March 2000, with a compliance deadline of 23 September 2000. The obligations imposed by this AD are clear and specific. Operators of Fokker F100 aircraft must ensure that all flight crew seat shoulder harnesses are inspected and functionally checked before the compliance date of 23 September 2000. This involves verifying that the shoulder harness assemblies are correctly attached to the inertia reel mechanism to prevent any incidents similar to the one reported overseas where a pilot's shoulder harness pulled out completely. Compliance with the AD requires adherence to the detailed instructions provided in Fokker Services’ SB F100-25-088 and referencing the RLD AD 1999-139. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, potentially leading to grounding of the aircraft until the required actions are completed. Non-compliance with the AD/F100/39 could have significant legal and operational repercussions. Although the Civil Aviation Regulations 1998 do not explicitly outline specific penalties for non-compliance with ADs, failure to adhere to such directives can result in enforcement actions by CASA. These actions may include fines, operational restrictions, or even the suspension of the aircraft's operating certificate. The seriousness of the issue, in this case, stemming from an overseas incident where a shoulder harness malfunctioned, underscores the importance of timely and thorough compliance. Ensuring the safety of flight crew is paramount, and any negligence in this regard can lead to severe civil and criminal liabilities for the aircraft operators.
