Project OS 01/11 - CASR Part 135 - Australian air transport operations - smaller aeroplanes
Accident rate analysis for Australian air transport operations (consisting of charter and regular passenger transport (RPT) operations) over the last two decades has outlined significant accident rate disparities between low capacity charter and low capacity RPT and high capacity RPT. The 2017 CASA Sector Risk Profile for the small aeroplane transport sector revealed small aeroplane unscheduled operations (charter) had an accident rate 11 times greater than small aeroplane scheduled operations (RPT).
This risk profile identified that the top five safety factors contributing to occurrences in the small aeroplane sector were monitoring and checking, assessing and planning, communicating / coordinating, pre-flight inspection and aircraft handling. Pilot training, supervision and mentoring play critical roles in developing pilot skills for managing high frequency occurrence types.
The key new proposals for Part 135 of CASR have been developed to reduce the size of the disparity in accident rates between small aeroplane charter and small aeroplane RPT. As outlined earlier, the merging of charter and RPT to form air transport operations provides new opportunities for existing charter operators in relation to the types of services they can offer the community. The provision of this opportunity requires the reduction, but not necessarily the complete elimination, of the disparity in accident rates.
Part 135 of CASR mainly focuses on controlling risk through additional administrative (procedural) defences however it does also require additional equipment, notably TAWS for some aircraft. The TAWS fitment requirement (outlined earlier for aeroplanes over 5 700kg) is based on Part I of Annex 6 to the Chicago Convention and EASA standards. CASA had originally proposed the fitment of a minimum of TAWS-Class B for aeroplanes with a MOPSC greater than 5 which aligned with the Federal Aviation Administration of the USA (FAA) and Transport Canada rules however this was changed after discussion with the Aviation Safety Advisory Panel Technical Working Group. The FAA mandated TAWS for new AOC holders from 2001 and for existing AOC holders from 2005.
The proposed regulations would set the minimum acceptable standards applicable to smaller aeroplanes that are conducting air transport operations.
Some of the changes incorporated into Part 135 of CASR are:
- Enabling extant charter operators, by merging of the concepts of charter and regular public transport into air transport and providing a common level of safety, to conduct fixed scheduled flights that are available to persons generally (an ability currently requiring an RPT AOC).
- Where the aircraft type has a master minimum equipment list, require aeroplanes flown internationally, or domestically under the IFR, to be operated in accordance with a minimum equipment list.
- The proposed regulations, where possible, allow for an outcomes-based approach to be adopted in the operator's exposition procedures.
- Relaxation of aerodrome requirements and require operators to ensure that aerodromes are suitable for the take-off and landing of the aeroplane, subject to the applicable performance requirements in Subpart 135.F and the Part 135 MOS.
- Relaxation of simulator requirements for aeroplanes certificated with greater than nine passenger seats but operated with a MOPSC of nine or less.
- Align with ICAO standards and alleviate existing requirements for the carriage and use of oxygen by non-pressurised aeroplanes when operating for no longer than 30 minutes between 10 000 ft and FL130.
- Modified performance provisions based on CAOs 20.7.2, 20.7.1B and 20.7.4.
- Require take-off alternate aerodromes under certain conditions.
- Require sterile cockpit operations during certain flight phases.
- Require operators to specify certain procedures for flights of prescribed single-engine aeroplanes (formerly known as ASETPA).
- Define suitable forced landing areas and modify overwater flight rules for prescribed single-engine aeroplanes.
- The proposed definition of suitable forced landing area encompasses areas of ground and, for prescribed single-engine aeroplanes, certain areas of water (subject to specific conditions).
- Require operators to specify procedures for determining how, and by whom, operational control for a flight is to be exercised.
- Require journey logs for each flight (although the journey log could be combined with other documentation).
- Enable operators to flexibly define procedures for providing updated information in relation to a multi-journey flight in cases where keeping copies of updated information on the ground is impractical.
- Require at least one member of the aeroplane’s flight crew when operating at night under the visual flight rules to be authorised under Part 61 of CASR to conduct an instrument flight rules (IFR) flight.
- Require information about search and rescue (SAR) services to be readily accessible to flight crew members, and for information about emergency and survival equipment carried on an aeroplane to be available for on-forwarding by the operator to a rescue coordination centre (RCC).
- Require aeroplanes over 5 700 kg MTOW when flown under night VFR or IFR rules in the conduct of passenger or medical transport operations to be fitted with terrain awareness warning system (TAWS) equipment.
- Turbine-engine aeroplanes over 5 700kg are to be fitted with TAWS-Class A equipment. Piston-engine aeroplanes over 5 700kg are to be fitted with TAWS-Class B equipment.
- Modified requirements for the fitment of airborne weather radar equipment.
- Training and checking requirements for all crew.
