COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Short SD3-30 Series Aeroplanes
AD/SD3-30/17
Amdt 1
Fuel Pipe Fumeproof Shrouds 9/86 DM
Applicability: All model SD3-30 with S/Nos SH3002 to SH3099, SH3102 and SH3105. Requirement: Action in accordance with Shorts SB SD330-28-29, Rev. 1.
Compliance: 1. Carry out "Inspection of the collector tank housings for evidence of fuel leakage" called for in the Shorts Maintenance Programme (zonal inspection 5-27-01, page 6 item 17) at every second 'A' check (120 hours time in service) after 31 December 1985 until modified.
2. Modify before 30 September 1986.
3. On completion of the modification, the inspection intervals referred to in item one
- of the Compliance may return to the normal maintenance programme intervals.
Background: The manufacturer advises that operational experience has found that certain existing fumeproof shrouds can deteriorate and become porous. New shrouds manufactured to an improved specification have therefore been introduced. This Directive has been amended to include the latest Revision of the Requirement Document.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safe operation of civil aircraft in Australia, addressing gaps in safety standards and compliance. One specific area of concern addressed by these regulations is the maintenance and inspection of aircraft components to prevent failures that could compromise safety. A notable piece of legislation within this framework is the Airworthiness Directive (AD) concerning fuel pipe fumeproof shrouds for Short SD3-30 series aeroplanes, specifically identified by serial numbers SH3002 to SH3099, SH3102, and SH3105. This AD was introduced to address the issue of deteriorating fumeproof shrouds, which can lead to fuel leakage and potential hazards. The directive mandates specific inspections and modifications to ensure the integrity of these components, reflecting the policy objective of maintaining high safety standards in civil aviation. Compliance with these directives is crucial for operators to ensure the continued airworthiness of their aircraft.
Scope and Application
The Civil Aviation Safety Authority (CASA) issued the Airworthiness Directive (AD) SD3-30/17 under the Civil Aviation Regulations 1998. This directive applies specifically to all Short SD3-30 model aeroplanes with serial numbers ranging from SH3002 to SH3099, SH3102, and SH3105. The directive mandates actions to be taken in accordance with Shorts Service Bulletin (SB) SD330-28-29, Revision 1. The primary requirement involves conducting an inspection of the collector tank housings for evidence of fuel leakage as part of the zonal inspection 5-27-01 at every second 'A' check, which is after 120 hours of time in service. This inspection is required until the specified modification is completed. The directive further mandates that any necessary modifications must be completed before 30 September 1986. Upon completion of these modifications, the inspection intervals can revert to the normal maintenance programme intervals. The AD aims to address the issue of existing fumeproof shrouds that can deteriorate and become porous, with new shrouds manufactured to an improved specification introduced to mitigate this risk.
Key Provisions
The key operative sections of this legislation pertain specifically to the AD/SD3-30/17 Amendment 1, which addresses fuel pipe fumeproof shrouds for the model SD3-30 aircraft with serial numbers SH3002 to SH3099, SH3102, and SH3105. The main requirement (section 1) mandates an inspection of the collector tank housings for evidence of fuel leakage during every second 'A' check (which occurs after 120 hours of time in service) following 31 December 1985 until the specified modification is completed. Additionally, the modification itself must be carried out before 30 September 1986 (section 2). Once the modification is completed, the inspection intervals can revert to those outlined in the normal maintenance programme (section 3).
This Act imposes certain obligations on the operators of the specified SD3-30 aircraft. Primarily, operators must ensure that the inspections for fuel leakage in the collector tank housings are conducted as per the directive's schedule, specifically at every second 'A' check until the modifications are made. Additionally, operators are required to complete the necessary modifications to the fuel pipe fumeproof shrouds before the deadline of 30 September 1986, in accordance with the manufacturer's guidance and the latest revision of the Requirement Document. Failure to comply with these obligations could result in the aircraft being deemed unairworthy, leading to potential operational disruptions and safety risks.
Failure to adhere to the provisions of this Airworthiness Directive can result in severe consequences. Firstly, non-compliance with the inspection and modification requirements could lead to the aircraft being grounded, as it may not meet the necessary safety standards. Additionally, if the aircraft is operated without the required modifications, it could be subject to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for such breaches may include fines or other civil or criminal penalties as stipulated by relevant aviation safety regulations. The exact penalties are not specified in this particular directive but are generally determined based on the severity of the breach and the impact on aviation safety.
