Project CS 11/13 - Review of the airworthiness standard for Approved Single Engine Aeroplane (previously Approved Single Engine Turbine Powered Aeroplanes) operations and inclusion of the standard CASR Part 90 Manual of Standards
Project closed 24 December 2015.
CAO 100.5 has been amended and includes the outcomes of the Approved Single Engine Turbine Powered Aeroplanes (ASETPA) review and the incorporation of relevant maintenance actions from the associated Airworthiness Directives (ADs):
|AD||CAO 100.5 Appendix 1 paragraph number|
|AD/GAS/1: Rechargeable compressed gas cylinders||15|
|AD/REC/1: Maintenance of Cockpit Voice Recorders Systems||9|
|AD/SUPP/8: Towing release systems||12|
|AD/SUPP/16: Electrical hoist assemblies||13|
|AD/GEN/37: Emergency exits||10|
|AD/AIRCON/9: Combustion type cabin heaters||16|
|AD/EMY/2: Life jackets & inflatable flotation devices||11|
|AD/EMY/4: Life rafts||11|
|AD/Prop/2: Feathering Propellers - Functional Check||8|
|AD/Rad/47: Periodic Testing of ATC Transponders||14|
After the updated Approved Single Engine Turbine Powered Aeroplanes certification and airworthiness standards within CAO 100.5 have been utilised and reviewed, CASA plans to update the Part 42 and Part 90 MOS with the ASETPA standards as a separate legislative project.
The airworthiness standard for Approved Single Engine Turbine Powered Aeroplane (ASETPA) operations is currently published in Airworthiness Advisory Circular AAC 1-116.
In addition, the standard currently contained in AAC 1-116 is out of date, and is too specific in its requirements. For example, the current standard has the effect of limiting ASETPA operations only to aeroplanes fitted with PT6 engines. This precludes a number of other possible engines, and therefore aircraft types from being considered for ASETPA operations.
CASA Part 135 will shortly be made, and will introduce the concept of the Approved Single Engine Aeroplane, so a standard for such aircraft is required. Part 135 will not require that an Approved Single Engine Aeroplane be fitted with a turbine engine, so the standard must be adapted to cover all potential powerplants.
No change in the level of safety provided by the standard is envisaged, but requirements will be updated, adapted to suit multiple engine types and included in the Part 90 MOS.
The objective of the project is to update the ASETPA standard and adapt it to match the operational requirements which will be included in Part 135. The new requirements will be published in the MOS to CASR Part 90. No other changes will be necessary.
