AD/TSA-600/26 - Nacelle Fairing - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive framework for the regulation of civil aviation within Australia. Part 39 of these regulations, specifically Schedule of Airworthiness Directives, focuses on ensuring that aircraft maintain the highest standards of safety and airworthiness. One such directive, AD/TSA-600/26, addresses a specific issue with the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes, specifically relating to the modification of the nacelle fairing. This directive was introduced to mitigate the risk of flames from a potential engine fire entering the lower wing structure, thereby enhancing overall aircraft safety. The directive applies to models 600, 601, and 601P with serial numbers ranging from 0001 to 0799 and requires compliance before 1 March 1981.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, applies to Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes, particularly those with serial numbers ranging from 0001 to 0799 for models 600, 601, and 601P. This regulation is mandated by the Civil Aviation Safety Authority (CASA) and pertains to the modification of the nacelle fairing to prevent potential fire hazards. The legislation seeks to ensure that the lower engine nacelle aft fibreglass fairing is adequately reinforced to prevent flames from a possible engine fire from entering the lower wing structure. The compliance date for this directive is set before 1 March 1981, and it is enforceable throughout the Commonwealth of Australia, overseen by CASA. The regulation references Piper Service Bulletin No. SB600-83 or FAA AD 80-12-14, Amendment 39-3801, for the technical specifications and modifications required. There are no stated exclusions or exemptions in this particular directive, and it is applicable to all relevant aircraft operating within Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, provides detailed directives concerning the airworthiness of certain aircraft. Section (1) of the AD/TSA-600/26 mandates the modification of the nacelle fairing for Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. This requirement applies to models 600, 601, and 601P with serial numbers ranging from 0001 to 0799. The directive necessitates compliance with either Piper Service Bulletin No. SB600-83 or the Federal Aviation Administration Airworthiness Directive AD 80-12-14, Amendment 39-3801. This modification must be completed before 1 March 1981 to address the identified risk of an engine fire causing damage to the lower wing structure. Entities and individuals governed by these regulations must ensure that the specified modifications are carried out by qualified personnel in accordance with the referenced documents. This includes conducting thorough inspections to confirm the adequacy of the nacelle fairing and making any necessary adjustments to prevent flames from an engine fire from reaching the lower wing. It is crucial that these changes are documented and verified to maintain compliance with the safety standards set forth by the Civil Aviation Safety Authority. Failure to comply with the provisions outlined in AD/TSA-600/26 may result in significant legal consequences. Civil penalties can be imposed for non-compliance, and in more severe cases, criminal charges may be brought against those responsible for failing to adhere to the airworthiness directives. The maximum penalties for such offences can include substantial fines and, in cases involving criminal negligence, imprisonment. These stringent measures underscore the importance of adhering to the stipulated requirements to ensure the safety of aircraft operations.
