Overview
The Civil Aviation Regulations 1998, which were enacted to ensure the safe operation of aircraft in Australia, include a provision addressing the airworthiness of specific aircraft models. Part 39 of these Regulations, through the Schedule of Airworthiness Directives, mandates actions to be taken regarding Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes. This legislative instrument, specifically F2006B07277, aims to address a safety concern where the cockpit hydraulic brake lines of these aircraft models were found to be susceptible to damage by the aileron and rudder control rods. The Civil Aviation Safety Authority issued this directive to ensure that these aircraft remain airworthy and safe for operation. Compliance with this directive is required within a specified timeframe to mitigate the identified risk, thus aligning with the overarching policy objective of maintaining high safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 – 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority for the Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes. This regulation applies to all models TB9 and TB10 with serial numbers up to 755, with certain exceptions listed as serial numbers 630, 631, 634, 636, 643, 648, 649, 656, 657, 658, 659, 661, 662, 663, 664, 750, 751, 752, and 753. The directive requires action to be taken in accordance with Aerospatiale Socata Service Bulletin No. 33, with reference to Bureau Veritas AD 87-118(A). Compliance with this airworthiness directive must be achieved within 100 hours of time in service or at the next scheduled inspection for maintenance release issue following 30 October 1987, whichever comes first. This regulation operates under the jurisdiction of the Commonwealth of Australia and applies to the maintenance and operation of the specified aircraft models within Australian airspace, ensuring that the identified safety issue with the hydraulic brake lines is addressed effectively.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, include detailed Airworthiness Directives (ADs) that govern the operational safety and maintenance of certain aircraft. One such AD is AD/TB10/10, which pertains to the Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes. This directive mandates specific actions regarding the hydraulic brake line clearance (section 11/87). The directive applies to all models TB9 and TB10 up to serial number 755, excluding specific serial numbers such as 630, 631, 634, 636, 643, 648, 649, 656, 657, 658, 659, 661, 662, 663, 664, 750, 751, 752, and 753. The requirement is to take action in accordance with Aerospatiale Socata Service Bulletin No.33, referencing Bureau Veritas AD 87-118(A). Compliance with this directive must be achieved within 100 hours of time in service or at the next scheduled inspection for maintenance release issue after 30 October 1987, whichever comes first.
The obligations imposed by this AD necessitate that aircraft operators and maintenance personnel adhere to the specified actions to ensure the integrity of the hydraulic brake lines. The manufacturer has reported instances where the cockpit hydraulic brake lines were damaged by the aileron and rudder control rods, which necessitates these specific maintenance actions. Operators must ensure that the maintenance tasks are carried out as directed by Aerospatiale Socata Service Bulletin No.33, which includes inspecting, repairing, or replacing the hydraulic brake lines as necessary. Failure to comply with this AD can result in serious safety risks, potentially compromising the aircraft's braking system and overall flight safety.
Violating the provisions outlined in AD/TB10/10 can lead to serious consequences. Civil Aviation Safety Authority (CASA) has the authority to enforce these directives, and non-compliance can result in civil or criminal penalties. The specific penalties may vary depending on the severity and frequency of the breach, but they can include fines and, in severe cases, the grounding of the aircraft until compliance is achieved. The maximum penalties for such breaches are significant, reflecting the critical nature of ensuring aircraft airworthiness. It is imperative for operators to adhere strictly to the AD to avoid these potential repercussions and to maintain the safety standards required by Australian aviation regulations.
