COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
SAAB SF340 Series Aeroplanes
AD/SF340/62
Amdt 1
Engine Air Intake - Modification of Detachable Centre Inlet
13/98
Applicability: SAAB 340A series aircraft, serial number 004 through 159 (inclusive), and SAAB 340B series aircraft serial number 160 through 219 (inclusive) and 402 through 436 (inclusive), equipped with Aerospace Composite Technologies (ACT) Engine Air Intakes.
Requirement: Modify the detachable centre inlet of the engine air intake in accordance with SAAB AB Service Bulletin SAAB 340-30-073 dated 18 August 1997.
Note: SAD N0. 1-119R1 dated 08 October 1998 refers.
Compliance: Within two years of the effective date of the original issue of this Directive.
This amendment becomes effective on 3 December 1998.
Background: The design and manufacturing of the detachable centre inlet of the engine air intake produces two apertures at the rear of the component. These holes must be closed to comply with fire resistance design regulations.
This amendment increases the applicability of this Directive.
The original issue of this Airworthiness Directive became effective on 4 December 1997.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), are pivotal in ensuring the safety and airworthiness of aircraft operating in Australia. One particular legislative instrument, F2006B06991, amends the Schedule of Airworthiness Directives for the SAAB SF340 series aeroplanes, addressing a specific safety concern related to the engine air intake. Enacted in 1998, this legislative instrument was introduced to address a gap in the existing regulatory framework concerning the fire resistance of the detachable centre inlet of the engine air intake in certain SAAB 340A and 340B series aircraft. The policy objective was to mandate modifications to these aircraft to ensure compliance with fire resistance design regulations, thereby enhancing the overall safety of these aircraft. The requirement to close the apertures at the rear of the detachable centre inlet was aimed at preventing potential fire hazards, thereby mitigating risks associated with aircraft operations.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, governs the airworthiness directives for various aircraft, including the SAAB SF340 Series Aeroplanes. One such directive, AD/SF340/62 Amendment 1, pertains to the engine air intake modifications of the detachable centre inlet. This directive applies to SAAB 340A series aircraft with serial numbers ranging from 004 to 159, and SAAB 340B series aircraft with serial numbers ranging from 160 to 219 and 402 to 436, all of which are equipped with Aerospace Composite Technologies (ACT) Engine Air Intakes. The directive mandates that these aircraft must have their detachable centre inlet of the engine air intake modified in accordance with SAAB AB Service Bulletin SAAB 340-30-073 dated 18 August 1997, with reference to SAD N0. 1-119R1 dated 08 October 1998. Compliance with this directive is required within two years of the effective date of its original issue, which was 4 December 1997, with this amendment becoming effective on 3 December 1998. The directive aims to address fire resistance design regulations by closing two apertures at the rear of the engine air intake component.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an amendment to the Schedule of Airworthiness Directives concerning SAAB SF340 Series Aeroplanes (AD/SF340/62 Amdt 1). This amendment pertains to the modification of the detachable centre inlet of the engine air intake for certain SAAB 340A and 340B series aircraft. According to section (13/98), the modification applies to SAAB 340A series aircraft with serial numbers 004 through 159, and SAAB 340B series aircraft with serial numbers 160 through 219 and 402 through 436, provided they are equipped with Aerospace Composite Technologies (ACT) Engine Air Intakes. The directive mandates that the detachable centre inlet of the engine air intake be modified in accordance with SAAB AB Service Bulletin SAAB 340-30-073 dated 18 August 1997, as referenced in SAD N0. 1-119R1 dated 08 October 1998.
This Airworthiness Directive imposes specific obligations on the operators and owners of the affected aircraft. The primary requirement is to ensure that the detachable centre inlet of the engine air intake is modified as specified by SAAB AB Service Bulletin SAAB 340-30-073, within two years from the effective date of the original issue of this Directive, which was 4 December 1997. The modification is crucial to close two apertures at the rear of the component to comply with fire resistance design regulations. Failure to comply with these requirements may result in the aircraft being deemed non-airworthy, potentially leading to grounding and other regulatory consequences.
The Civil Aviation Regulations 1998 outline potential offences and penalties for non-compliance with the Airworthiness Directive. Specifically, operators and owners who fail to comply with the mandated modifications within the stipulated timeframe risk facing civil penalties, including fines and potential revocation of the aircraft's airworthiness certificate. Additionally, criminal penalties may apply if the non-compliance results in a significant safety hazard or incident, potentially leading to imprisonment and further financial penalties. The exact penalties are not explicitly stated in the legislative instrument, but they are in line with the regulatory framework governing aviation safety in Australia.
