AD/TSA-600/7 Amdt 16 - Nose Landing Gear Drag Brace Trunnion and Actuator Fasteners - Inspection

Overview

The Civil Aviation Regulations 1998, amended through F2006B07516, represent an instrumental legislative instrument aimed at ensuring the ongoing airworthiness of specific aircraft models, particularly the Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes. Enacted by the Australian Parliament, this regulation targets a critical safety concern by addressing the structural integrity of the nose landing gear drag brace trunnion and actuator fasteners. The policy objective is to mitigate the risk of in-flight failures by mandating regular inspections and, if necessary, the replacement of these critical components to ensure compliance with safety standards. The regulation is designed to be enforced through the Civil Aviation Safety Authority, which oversees the implementation of airworthiness directives to safeguard the aviation industry. This legislative instrument underscores the importance of proactive maintenance and adherence to specific timelines, ensuring that aircraft remain safe and compliant with regulatory standards. By setting clear intervals for inspections and necessary actions, the regulation aims to prevent potential hazards that could compromise flight safety, thus protecting both the aviation industry and the public it serves.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically Part 39 - 105, issues Airworthiness Directives to ensure the safe operation of aircraft. One such directive, AD/TSA-600/7 Amendment 16, pertains to the Aerostar (Piper/Ted Smith) 600 and 700 Series aeroplanes. This directive mandates inspections of the nose landing gear drag brace trunnion and actuator fasteners for all models with Air Frame Sequence Numbers prior to 0385. Compliance with this directive is required within 100 hours of time in service after 15 March 1978, and subsequently at intervals not exceeding 100 hours of time in service until the fasteners are replaced, as detailed in Ted Smith Corporation Service Bulletin No. SB600-59, Revision 1. The directive applies to aircraft operators and maintenance personnel within the Australian jurisdiction, overseen by CASA to ensure adherence to safety standards. The directive does not specify exclusions or exemptions, and its application is enforced through CASA's regulatory oversight and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive (AD) that applies to Aerostar (Piper/Ted Smith) 600 and 700 Series aeroplanes (AD/TSA-600/7Amdt 16). This directive mandates an inspection of the nose landing gear drag brace trunnion and actuator fasteners. The directive applies to all models with Air Frame Sequence Numbers prior to 0385 (AD/TSA-600/7Amdt 16). Compliance with this directive is necessary unless the required inspection has already been completed. The inspection must be performed within 100 hours of time in service after 15 March 1978, and subsequently, at intervals not exceeding 100 hours of time in service until the fasteners are replaced (AD/TSA-600/7Amdt 16). The AD imposes specific obligations on the parties or entities it governs. Operators of the affected aircraft must ensure that the inspection of the nose landing gear drag brace trunnion and actuator fasteners is performed by qualified personnel in accordance with the detailed instructions provided in Ted Smith Corp. SB No. SB600-59, Rev. 1. This ensures that the aircraft remain airworthy and meet the safety standards set forth by the Civil Aviation Safety Authority (CASA). Operators must also maintain records of all inspections and any actions taken in response to findings from these inspections, as this documentation may be required for regulatory compliance and audits. Failure to comply with the AD could result in significant legal and operational consequences. The Civil Aviation Regulations 1998 outline various offences and penalties for non-compliance with airworthiness directives. In the case of breaching this AD, the penalties can be severe. Civil penalties may include fines up to a substantial amount, depending on the severity and circumstances of the breach. Additionally, CASA has the authority to issue enforcement actions, such as grounding the aircraft until compliance is achieved, which can significantly disrupt operations and incur additional costs for the operator. Criminal penalties may also apply if the non-compliance results in safety hazards or accidents, leading to more severe consequences including imprisonment.
