COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Aerospatiale (Socata) TBM 700 Series Aeroplanes
AD/TBM 700/13
Amdt 1
Oil Cooler Interference 10/96
Applicability: TBM 700 aircraft serial numbers 63, 68 to 71, 74, 76 to 106 and 108.
Requirement: To prevent interference between the oil cooler outlet protective screen and the oil cooler core resulting in an engine oil leak, modify the oil cooler in accordance with Socata TBM 700 Aircraft Service Bulletin Number SB 70-060-79 Amendment 1.
Note: DGAC Airworthiness Directive 95-034(B)R1 refers.
Compliance: Effective 12 September 1996; unless previously accomplished in accordance with the original issue of this directive, before further flight.
Background: This directive was originally issued in July 1995 to require a modification of the oil cooler installation. The modification addressed reports of a possible oil leak developing if interference existed between the oil cooler core and the oil cooler outlet protective screen. This amendment reflects the manufacturer's revision to the requirement document. The revision, in part, clarifies the aircraft applicable and that the protective screen is to be removed permanently.
The original issue of this Airworthiness Directive became effective on 22 June 1995.
Overview
The Civil Aviation Regulations 1998, as amended by AD/TBM 700/13 Amendment 1, was enacted to address the safety issue of potential oil leaks in certain Aerospatiale (Socata) TBM 700 Series aeroplanes due to interference between the oil cooler outlet protective screen and the oil cooler core. This directive applies specifically to TBM 700 aircraft with serial numbers 63, 68 to 71, 74, 76 to 106, and 108. The amendment, effective from 12 September 1996, mandates that these aircraft be modified in accordance with Socata TBM 700 Aircraft Service Bulletin Number SB 70-060-79 Amendment 1, which includes the permanent removal of the oil cooler outlet protective screen. This modification was prompted by reports of oil leaks occurring when such interference took place, and the directive aims to ensure that these aircraft comply with the required safety standards before further flight. The Civil Aviation Safety Authority, under the authority of the Parliament of Australia, introduced this directive to enhance aviation safety and prevent potential hazards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Aerospatiale (Socata) TBM 700 Series Aeroplanes, with particular reference to the AD/TBM 700/13 Amendment 1 concerning oil cooler interference. This regulation is applicable to TBM 700 aircraft with serial numbers 63, 68 to 71, 74, 76 to 106, and 108. The requirement outlined is to prevent potential engine oil leaks caused by interference between the oil cooler outlet protective screen and the oil cooler core. Compliance with this directive necessitates modifying the oil cooler in accordance with Socata TBM 700 Aircraft Service Bulletin Number SB 70-060-79 Amendment 1. The directive became effective on 12 September 1996, stipulating that the modification must be completed before further flight unless it had already been accomplished in line with the original directive issued on 22 June 1995. The directive references DGAC Airworthiness Directive 95-034(B)R1, and this amendment clarifies the scope of applicable aircraft and mandates the permanent removal of the protective screen to mitigate the risk of oil leaks.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39 - 105, detail specific Airworthiness Directives for particular aircraft models. One such directive pertains to the Aerospatiale (Socata) TBM 700 Series Aeroplanes, particularly AD/TBM 700/13 Amendment 1 (AD/TBM 700/13 Amdt 1), which addresses oil cooler interference issues. This directive applies to TBM 700 aircraft with serial numbers 63, 68 to 71, 74, 76 to 106, and 108 (Section 1). The primary requirement is to modify the oil cooler to prevent interference between the oil cooler outlet protective screen and the oil cooler core, which could otherwise result in an engine oil leak (Section 2). The modification must be conducted in accordance with Socata TBM 700 Aircraft Service Bulletin Number SB 70-060-79 Amendment 1, and specifically, the protective screen must be removed permanently to mitigate the risk of leaks (Section 3).
The Act imposes clear obligations on the owners and operators of the specified TBM 700 aircraft. They must ensure that the oil cooler modifications are carried out before further flight if they have not already been completed in accordance with the original directive issued on 22 June 1995 (Section 4). This requirement must be met by 12 September 1996, as specified in the amendment (Section 5). Failure to comply with this directive could result in the aircraft being deemed unairworthy, thus preventing any further operation until the necessary modifications are completed.
Breaching the requirements set out in AD/TBM 700/13 Amdt 1 can have serious consequences. The Civil Aviation Safety Authority (CASA) enforces these directives rigorously, and non-compliance can lead to penalties under the Civil Aviation Act 1988. The potential civil penalties include fines, and in severe cases, the grounding of the aircraft. Additionally, operators may face criminal charges if their negligence results in safety incidents, which could lead to imprisonment. The exact penalties depend on the severity of the breach and the resultant impact on aviation safety.
