Consultation Draft - CD 1423MS
CD 1423MS - Proposed amendments to CAO 100.5 - General requirements in respect of maintenance of Australian aircraft
In preparation for the application of Parts 42 and 145 of the Civil Aviation Safety Regulations 1998 (CASR) to other than regular public transport operations, CASA is reviewing on-going and general certification and maintenance matters currently covered within Airworthiness Directives (ADs), legislative and non-legislative instruments and Aviation Advisory Circulars (AACs). Where those matters are more appropriately dealt with via Civil Aviation Order (CAO) 100.5, CASA is seeking to incorporate those matters within the CAO.
Purpose and scope of the proposed amendments
The airworthiness standard for Approved Single Engine Turbine Powered Aeroplane (ASETPA) operations is currently published in AAC 1-116 and an associated letter instrument. In the short term, CASA intends to deal with ASETPA matters within CAO 100.5 for aircraft whose maintenance is covered by under the Civil Aviation Regulations 1988 (CAR). In the longer term, CASA intends to create a Part 21 Manual of Standards (MOS) and utilise the new MOS and the existing Part 42 and 90 MOS to deal with ASETPA.
This consultation draft provides for the outcomes sought by CASA Standards Development projects:
- CS11/13 Review of the airworthiness standard for Approved Single Engine Aeroplane (previously Approved Single Engine Turbine Powered Aeroplanes) operations and inclusion of the standard Part 90 Manual of Standards
- MS 14/06 Migration of maintenance-related ADs and approval of advisory material for maintenance.
The policy of recognising certain instructions as maintenance data (if current maintenance data is deficient) contained within the cancelled CASA instrument 515/11 Approval of instructions as maintenance data would be re-introduced by this amendment.
The proposed amendment would also more permanently provide for the policy outcomes currently dealt with by these CASA instruments:
- 307/03 Direction - headsets are not components
- 347/07 Direction - night vision goggles are not components
- 481/07 Approval - maintenance release form
- 482/07 Direction - Information to be entered on a maintenance release
- EX90/12 Exemption - Time in service and determination non application of CAO 100.5.
Following a review of Australian unique ADs, a number of ADs covering maintenance requirements were identified that did not fully satisfy the requirements for issuing of an AD under Part 39 of CASR. The ADs identified for transition are:
- AD/PFP/1: Propellers
- AD/Prop/2: Feathering Propellers - Functional Check
- AD/GEN/37: Emergency exits
- AD/EMY/2: Life jackets & inflatable flotation devices
- AD/EMY/4: Life rafts
- AD/REC/1: All CVR Systems
- AD/SUPP/16: Electrical hoist assemblies
- AD/Rad/47: Periodic Testing of ATC Transponders
- AD/SUPP/8: Towing release systems
- AD/GAS/1: Rechargeable compressed gas cylinders
- AD/AIRCON/9: Combustion type cabin heaters.
In addition, a particular requirement detailed in cancelled AD/GEN/48 Amdt 3 has been determined to be still applicable. The requirement for ensuring the integrity of the fire protection in toilet areas on an aircraft would be reinstated.
The Part 42 MOS will be concurrently amended to cover these maintenance requirements for aircraft covered by Part 42 of CASR.
