COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes
AD/TB10/7 Battery Tray Installation 10/85
Applicability: All models TB9 and TB10 series with S/nos up to 441 but excluding S/nos 343, 382, 414, 423, 425 to 429 and 434 to 438.
Requirement: Inspect and modify the battery tray installation in accordance with the requirements detailed in Socata Service Letter No. 18 under description paragraph 1. Pay particular attention to surrounding fuselage structure for signs of electrolyte spillage and subsequent damage.
Note: French AD 85-130-(A) refers.
Compliance: Within 50 hours time in service after 31 October 1985.
Background: The battery tray installation may be such that electrolyte spillage from the battery could cause fuselage structural damage due to corrosion.
Overview
The Civil Aviation Regulations 1998, which are part of a broader legislative framework to ensure the safety of civil aviation in Australia, were enacted by the Australian Parliament to regulate the safety of aircraft operations. Among the many directives aimed at maintaining airworthiness, PART 39 - 105 addresses Airworthiness Directives specific to certain aircraft types. One such directive, AD/TB10/7, pertains to the Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes. This directive was introduced to address the identified problem of potential electrolyte spillage from the battery tray, which could lead to fuselage structural damage due to corrosion. The policy objective of this directive is to ensure that the battery tray installation is inspected and modified as necessary to prevent such damage, thereby enhancing the overall safety and airworthiness of the affected aircraft. Compliance with this directive is mandatory and must be achieved within 50 hours of time in service after 31 October 1985.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate the applicability of airworthiness directives concerning the Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes, focusing on the installation of the battery tray. This regulation applies to all models of the TB9 and TB10 series aeroplanes with serial numbers up to 441, excluding certain serial numbers such as 343, 382, 414, 423, 425 to 429, and 434 to 438. The requirement outlined in AD/TB10/7 mandates that these aeroplanes must undergo an inspection and modification of the battery tray installation in accordance with the specifications detailed in Socata Service Letter No. 18, with a particular emphasis on examining the surrounding fuselage structure for any signs of electrolyte spillage and resultant damage. Compliance with these directives is necessary within 50 hours of time in service following 31 October 1985. The regulation's intent is to prevent potential structural damage caused by electrolyte spillage from the battery, which could lead to corrosion and compromise the aircraft's integrity. This directive extends to ensure that the modifications align with French AD 85-130-(A).
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, mandates that all models of Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes with serial numbers (S/nos) up to 441, excluding certain specific serial numbers such as 343, 382, 414, 423, 425 to 429, and 434 to 438, must undergo an inspection and modification of their battery tray installations (section 10/85). This requirement is detailed in Socata Service Letter No. 18, which necessitates particular attention to the surrounding fuselage structure to check for any signs of electrolyte spillage and related damage. It is also noted that this directive corresponds with French AD 85-130-(A).
Entities governed by this Act, including aircraft operators, maintenance providers, and relevant aviation authorities, must ensure that the battery tray installation on the specified TB9 and TB10 series aeroplanes is inspected and modified as required within 50 hours of time in service after 31 October 1985. This involves detailed checks of the battery tray installation to prevent electrolyte spillage, which could lead to structural damage to the fuselage due to corrosion. The compliance deadline is critical, and failure to adhere to it may result in non-compliance with regulatory standards.
Failure to comply with the requirements outlined in section 10/85 of the Civil Aviation Regulations 1998 can lead to significant consequences. While specific offences, penalties, or civil and criminal consequences are not detailed in the provided text, it is implied that non-compliance with safety directives can result in severe repercussions. These may include the grounding of affected aircraft, fines, and other enforcement actions by the Civil Aviation Safety Authority (CASA). The exact penalties could vary based on the severity of the breach and the specific regulatory frameworks in place at the time of the violation.
