Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) and enacted by the Australian Parliament, were established to ensure the safety and efficiency of civil aviation in Australia. One legislative instrument, F2006B07290, specifically addresses the safety of Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes through Airworthiness Directive AD/TB10/22 Amendment 1. This amendment was introduced to address a safety concern identified by the French Civil Aviation Safety Authority (DGAC), which required reinforcement of the front seat structure in certain models of these aircraft to prevent potential failures. The directive aims to ensure that the modifications are carried out within a specified timeframe to maintain airworthiness and comply with international safety standards.
This legislative instrument underscores the importance of addressing specific safety issues in civil aviation through timely and precise regulatory action, ensuring that aircraft continue to meet the necessary safety standards. The compliance requirements are clearly outlined, mandating that the actions specified in Socata's Service Bulletin 10-075-25 Amendment 1 be implemented within a defined period after a specified date, or at the next maintenance inspection, whichever comes first. This approach reflects the overarching policy objective of the Civil Aviation Regulations 1998 to protect public safety and maintain the integrity of civil aviation operations in Australia.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates that Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes adhere to the Airworthiness Directives outlined in AD/TB10/22 Amendment 1, which pertains to the front seats of these aircraft. This regulation applies to model TB9 and TB10 aircraft with front seats featuring a tilting back-rest, installed from February 1991 on aircraft up to serial number 1479, with certain exceptions including aircraft with specific serial numbers. Compliance with the directive is mandatory, requiring actions to be taken in accordance with Socata TB Service Bulletin 10-075-25 Amendment 1, which provides the necessary reinforcement for the front seat structure. The directive applies to aircraft within the Commonwealth of Australia, and it is enforced by the Civil Aviation Safety Authority. There are no exclusions noted in the text, but certain aircraft serial numbers are specifically excluded from the directive. The regulation also references DGAC AD 94-114(A)R1 and mandates compliance within 50 hours of time in service after 8 December 1994, or at the next inspection for maintenance release, whichever occurs first.
Key Provisions
The Civil Aviation Regulations 1998, particularly in Part 39 - 105, outlines specific Airworthiness Directives (AD) for certain aircraft models. One such AD, AD/TB10/22 Amendment 1, pertains to the front seats of the Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes. The directive applies to these models with a tilting back-rest installed from February 1991, up to a specific serial number, with some serial numbers excluded. The key requirement is that actions must be taken in accordance with Socata TB Service Bulletin 10-075-25 Amendment 1, which details the necessary modifications to the seat structure. The compliance deadline is either within 50 hours of time in service after 8 December 1994 or at the next inspection for maintenance release issue, whichever comes first.
Entities governed by these regulations, such as aircraft operators and maintenance providers, must ensure that the modifications outlined in the service bulletin are implemented within the stipulated timeframe. This involves reinforcing the front seat structure to meet the safety standards specified by the Directorate General of Civil Aviation (DGAC). The modifications must be carried out by qualified personnel who are familiar with the specific requirements of the service bulletin. Compliance with the AD is critical to maintaining the airworthiness of the affected aircraft.
Failure to comply with AD/TB10/22 Amendment 1 may result in significant consequences. Non-compliance can lead to penalties and legal action, as the AD is a legal requirement enforced by the Civil Aviation Safety Authority (CASA). The specific consequences for breach of these regulations are not detailed in the provided text, but generally, non-compliance with ADs can result in fines, suspension of aircraft operation certificates, and other enforcement actions. Operators and maintenance providers must take proactive steps to ensure that all applicable ADs are adhered to, avoiding potential penalties and ensuring the safety of air travel.
