AD/PA-34/25 - Vertical Fin and Stabilator Attachments - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, represent a comprehensive framework for regulating civil aviation safety within Australia. Among its various provisions, Part 39 - 105 outlines the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives, which are critical for maintaining the safety standards of aircraft operations. One such directive, AD/PA-34/25, focuses on the inspection of vertical fin and stabilator attachments on Piper PA-34 (Seneca) Series aeroplanes. This directive was introduced to address potential safety issues related to the structural integrity of the vertical fin and stabilator, ensuring that these components are regularly inspected to prevent failures that could compromise flight safety. The policy objective is to mandate timely and effective inspections to mitigate risks and uphold the highest safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, governs the maintenance and inspection requirements for specific Piper PA-34 (Seneca) series aeroplanes. This legislative instrument applies to all model PA-34-200 aeroplanes with serial numbers ranging from 34-E4 to 34-7450220 and all model PA-34-200T aeroplanes with serial numbers from 34-7570001 to 34-7770441. The directive mandates that inspections of the vertical fin and stabilator attachments be conducted within 25 hours of time in service following 16 January 1978 for Part 1, and within 100 hours of time in service for Part II, as detailed in Piper Service Bulletin No. 579. The regulation applies nationally across Australia, overseen by the Commonwealth, and aims to ensure the continued airworthiness of specified aircraft models by enforcing mandatory inspection protocols. The scope of this directive does not extend beyond the specified serial numbers of the Piper PA-34 series aeroplanes and the particular inspection requirements outlined.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, outlines the airworthiness directives, including AD/PA-34/25 concerning the Piper PA-34 (Seneca) Series Aeroplanes. This directive focuses on the vertical fin and stabilator attachments, demanding inspections to ensure safety (Section 39-105). The directive applies to all model PA34-200 with serial numbers (S/Nos.) 34-E4, 34-7250001 to 34-7450220, and all model PA-34-200T with S/Nos. 34-7570001 to 34-7770441 (Section 39-105(1)). The compliance schedule requires an initial inspection within 25 hours of time in service after 16 January 1978, followed by a subsequent inspection within 100 hours of time in service after the same date (Section 39-105(2)). Under the Civil Aviation Regulations 1998, operators of the specified Piper PA-34 (Seneca) Series Aeroplanes must adhere to the outlined inspection requirements. This involves ensuring that all model PA34-200 and PA-34-200T within the specified serial number ranges undergo the mandated inspections at the designated intervals. Operators must also maintain records of these inspections to demonstrate compliance with the directive (Section 39-105(3)). Additionally, operators are required to address any identified issues with the vertical fin and stabilator attachments promptly to maintain the airworthiness of the aircraft (Section 39-105(4)). Failure to comply with the airworthiness directive AD/PA-34/25 can lead to significant legal consequences. Under the Civil Aviation Regulations 1998, non-compliance may result in enforcement actions by the Civil Aviation Safety Authority (CASA). The potential penalties for not adhering to the directive can include fines and other administrative actions. In severe cases, CASA may impose more stringent measures such as grounding the aircraft or imposing operational restrictions until the necessary inspections and repairs are completed (Section 39-105(5)). The exact penalties and consequences are determined based on the severity of the non-compliance and the impact on aviation safety.
