AD/S-PUMA/22 - Tail Rotor Shaft

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, constitute a comprehensive set of rules governing various aspects of civil aviation safety, including the issuance of airworthiness directives. PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITYSCHEDULE OF AIRWORTHINESS DIRECTIVES specifically addresses the maintenance and safety standards for aircraft types, with AD/S-PUMA/22 focusing on the Eurocopter AS 332 (Super Puma) Series Helicopters. This directive was introduced to address the identified issue of potential cracks in the tail rotor flapping hinge retainers, as highlighted by Eurocopter’s Mandatory Service Bulletin 05.00.41 dated January 29, 1996, and referenced by DGAC AD 96-074-057(B). The overarching policy objective is to ensure the continued airworthiness and safety of all model AS 332 helicopters by mandating specific actions to rectify and prevent the identified safety concern. Compliance with these directives is imperative to uphold the stringent safety standards set forth by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/S-PUMA/22, pertains to all model AS 332 helicopters, commonly known as the Super Puma series. This directive is applicable to any entity operating these helicopters within the jurisdiction of the Commonwealth of Australia, ensuring compliance with safety standards set forth by the Civil Aviation Regulations 1998. The primary focus of this directive is to address a critical safety issue identified in the tail rotor shaft, which necessitates action in accordance with the Eurocopter Mandatory Service Bulletin 05.00.41 dated January 29, 1996. Operators of these helicopters are required to comply with the specifics outlined in the Requirement Document, which references DGAC AD 96-07-4-057(B), to rectify the issue of a crack in one of the tail rotor flapping hinge retainers as advised by the manufacturer. This directive underscores the necessity for rigorous safety measures to be implemented across all relevant operations.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, mandates specific actions for the maintenance and operation of Eurocopter AS 332 (Super Puma) series helicopters. The regulation in question, AD/S-PUMA/22, pertains to the tail rotor shaft and applies to all model AS 332 helicopters (Section 1). The requirement is that all affected helicopters must undergo maintenance actions as detailed in the Eurocopter Mandatory Service Bulletin 05.00.41 dated January 29, 1996 (Section 2). Compliance must align with the specifications outlined in the Requirement Document (Section 3). Operators and owners of the AS 332 series helicopters are obligated to adhere strictly to the requirements set out in the AD/S-PUMA/22. This includes conducting inspections and necessary repairs or replacements of the tail rotor flapping hinge retainers to prevent any potential cracking, as identified by the manufacturer (Section 4). Ensuring that all maintenance and operational procedures comply with the relevant ADs (Airworthiness Directives) is critical for maintaining the airworthiness and safety of these aircraft. Failure to comply with these provisions may result in severe repercussions for both the operator and the aircraft's airworthiness status. Failure to comply with the AD/S-PUMA/22 can lead to significant civil and criminal consequences. The primary concern is the potential for compromising the safety and airworthiness of the aircraft, which could result in accidents or incidents (Section 5). Additionally, non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Penalties can include fines, suspension or revocation of airworthiness certificates, and potential criminal charges against individuals responsible for the oversight or operation of the non-compliant aircraft. The exact penalties can vary, but they are intended to ensure strict adherence to safety regulations. In summary, the Civil Aviation Regulations 1998 mandate that all AS 332 (Super Puma) series helicopters must comply with the AD/S-PUMA/22, which requires specific maintenance actions to address potential tail rotor shaft issues. Operators must ensure that their maintenance practices align with the specified bulletin and requirement documents. Failure to comply with these provisions can result in severe penalties, including fines, suspension or revocation of airworthiness certificates, and potential criminal charges.
