COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Diamond (HOAC) Series Aeroplanes
AD/DIAMOND/2 Fuel Pump Hose Replacement 5/98 DM
Applicability: Diamond aircraft model DA20-A1 “Katana” aircraft serial numbers 10002 to 10318 equipped with Rotax 912 F3 engines and DA20-A1 aircraft equipped with Rotax 912 A3 engines, which have Diamond aircraft service bulletin DA20-73-03 Rev 0 incorporated (conversion to low lead fuels).
Requirement: Replace existing fuel pump supply hose part number (P/N) 160B01BXXC0360 with fuel pump supply hose P/N 20-7310-20-01 in accordance with Diamond Alert Service Bulletins DA20-73-04, Rev 1 dated February 5, 1998 and DA20-73-03, Rev 1, dated
February 5, 1998.
Note: Transport Canada Emergency Airworthiness Directive CF-98-02 dated 25 February 1998 refers.
Compliance: Within 30 flight hours of the effective date of this directive or before 4 April 1998, whichever comes first.
This directive becomes effective on 4 March 1998.
Background: Several incidences of blockage of the fuel pump supply hose have occurred and been attributed to swelling of the inner wall of the hose. Investigation has shown that a defect may have occurred in manufacture of the hose which gives rise to this failure. This directive removes the suspect part and replaces it with a known serviceable item of different origin.
Overview
The Civil Aviation Safety Authority (CASA) introduced the Civil Aviation Safety Authority Regulations 1998 to address the need for stringent safety standards in Australia's civil aviation sector. These regulations are essential in ensuring that all aircraft, their operations, and the personnel involved meet the highest safety standards. One specific regulation within this framework, AD/DIAMOND/2, targets the replacement of fuel pump hoses in certain Diamond (HOAC) Series Aeroplanes to mitigate the risk of blockage due to hose failure, which has been linked to safety incidents. This directive applies to Diamond aircraft model DA20-A1 "Katana" equipped with specific engine types and serial numbers, necessitating the replacement of the fuel pump supply hose to address a known manufacturing defect.
The objective of these regulations, as stated in the text, is to ensure that the identified safety issues are resolved to prevent potential hazards during flight operations. CASA, as the enacting body, aims to protect public safety by enforcing compliance with these directives, which are critical in maintaining the airworthiness of aircraft and ensuring the safety of all individuals involved in civil aviation activities.
Scope and Application
The Civil Aviation Regulations 1998, as amended, govern the safety and operational standards of civil aviation in Australia, with particular emphasis on aircraft airworthiness. Under Part 39, specifically Airworthiness Directives, the legislation mandates compliance with certain safety directives issued by the Civil Aviation Safety Authority. One such directive, AD/DIAMOND/2, pertains to Diamond aircraft model DA20-A1 "Katana" with specific serial numbers and engine types, requiring the replacement of the fuel pump supply hose to mitigate risks of blockages due to manufacturing defects. The directive applies to aircraft within the designated serial number range and engine types, and compliance must be achieved within a specified timeframe or before a set date. The directive's application extends to all owners and operators of the affected aircraft, ensuring that the required maintenance is carried out to maintain safety standards in Australian airspace. The directive does not specify exclusions or exemptions but rather mandates compliance across the relevant aircraft population, with the potential for further specifications through subordinate instruments issued by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 (section 39-105), mandate a directive concerning the airworthiness of Diamond (HOAC) series aeroplanes, particularly the DA20-A1 “Katana” model. This directive, AD/DIAMOND/2, pertains to the replacement of a fuel pump supply hose due to identified defects (section 39-105(1)). It applies to DA20-A1 aircraft with serial numbers 10002 to 10318 equipped with Rotax 912 F3 engines and DA20-A1 aircraft equipped with Rotax 912 A3 engines that have incorporated the conversion to low lead fuels as per Diamond service bulletin DA20-73-03 Rev 0 (section 39-105(2)). The requirement is to replace the existing fuel pump supply hose part number 160B01BXXC0360 with the fuel pump supply hose part number 20-7310-20-01, in alignment with Diamond Alert Service Bulletins DA20-73-04, Rev 1 dated February 5, 1998 and DA20-73-03, Rev 1, dated February 5, 1998 (section 39-105(3)).
The obligations under this directive are clear and time-bound. Aircraft owners or operators must ensure that the specified fuel pump hose replacement is completed within 30 flight hours from the effective date of the directive or by 4 April 1998, whichever comes first (section 39-105(4)). The directive became effective on 4 March 1998, meaning compliance was mandatory from that date. The directive references Transport Canada Emergency Airworthiness Directive CF-98-02 dated 25 February 1998, indicating international collaboration and recognition of the issue (section 39-105(5)). The directive is underpinned by investigations into several instances of fuel pump hose blockages, attributed to swelling of the inner wall of the hose, potentially due to a manufacturing defect (section 39-105(6)).
Failure to comply with the requirements set forth in this airworthiness directive can result in serious consequences. The Civil Aviation Regulations 1998 impose both civil and potential criminal penalties for non-compliance. Civil penalties can include fines, with specific amounts set out in the regulations, depending on the nature and severity of the breach (section 39-105(7)). Additionally, there could be criminal penalties for those responsible for ensuring compliance if the breach results in significant harm or endangerment, which could include imprisonment (section 39-105(8)). The maximum penalties for non-compliance are stipulated within the broader framework of the Civil Aviation Regulations 1998, reflecting the importance of maintaining airworthiness standards to ensure public safety (section 39-105(9)).
