CASR Part 121 - Commercial air transport operations (aeroplanes)
The proposed regulations in Part 121 of the Civil Aviation Safety Regulations 1998 (CASR) will set the minimum acceptable standards applicable to large aeroplanes that are conducting passenger or cargo transport operations.
An air transport operation means an operation in an aircraft:
- that is conducted for hire or reward, or is otherwise publically available
- that is a passenger transport operation or a cargo transport operation.
A passenger transport operation involves the carriage of passengers in an aircraft, whether or not cargo is carried on the aircraft. This type of operation does not include:
- cost sharing operations
- aerial work operations; or
- an operation for the carriage of passengers in an aircraft with a certificate of airworthiness other than a standard certificate of airworthiness.
'Large aeroplanes' in Part 121 of CASR means an aeroplane:
- fitted with more than 9 passenger seats in its approved configuration; or
- with a maximum take-off weight (MTOW) of more than 8,618 kg.
Who Part 121 affects
- Air operators involved in current charter and RPT operations (passenger and cargo) in aeroplanes.
- Personnel including:
- flight crew members
- cabin crew
- ground and support personnel involved in the operation of aeroplanes engaged in charter or RPT (passenger and cargo) operations
- the travelling public.
Part 121 of CASR is currently under development through Standards Development Project OS 99/44, the key proposals are:
- single standard to be introduced for passenger transport services, regardless of whether Charter or RPT operations are involved
- Part 121 flights to be planned and operated under the instrument flight rules (IFR) only
- simplified performance regulations in accordance with Annex 8 and Annex 6 of International Aviation (the Chicago Convention)
- updated requirements for flight data recorders (FDRs) and cockpit voice recorders (CVRs) and the introduction of a requirement for the fitting of an underwater locating device (ULD) on long overwater flights
- re-introduction of the requirement for first aid kits and a new requirement for emergency medical kits and universal precaution kits on specified flights
- allowing up to 30 minutes without a requirement for flight crew supplemental oxygen above 10,000 feet (up to flight level [FL]130) for unpressurised aircraft
- flight and cabin crew members to be subject to more comprehensive training and checking requirements, including human factors training
- cabin crew to passenger seat ratio 1:50
- a greater focus on outcome based recency requirements rather than just prescriptive rules for flight crew
- alternative training and checking programs to allow operators to structure their own training and checking programs relevant to their fleets and flight crew
- restrictions to be placed on the crewing together of inexperienced pilots - green on green
- Operators to describe how they will manage multi-fleet flying by flight crew in their exposition
- more comprehensive provisions and incorporations of the MOS for:
- fuel based on Amendment 36 of Annex 6 to the ICAO Flight Planning and Fuel Management Manual (FPFMM) as the foundation guidance material
- alternate aerodrome requirements, and operational flight planning based on ICAO Annex 6 Part I standards
- extended diversion time operation (EDTO) provisions in accordance with ICAO Annex 6 Attachment D
- low visibility operations, including the use of enhanced vision systems (EVS) and head up display (HUD)
- performance based navigation (PBN) new approach classifications
- standard passenger and baggage weights (checked baggage to be weighed, baggage placement limits; operators provided with the means to establish standard weights, or different standard weights, to those legislated)
- relief for flight crew members, including cruise relief co-pilots
- narrow runway operations.
Part 121 operator's will require certification under Part 119 of CASR, with its requirements for:
- continuing airworthiness under an approved aircraft maintenance program
- operational risk management under a safety management system (SMS)
- fatigue risk management systems for crew
- procedural training and checking of flight crews under the operator's training and checking system - either in-house or provided by an arrangement with a Part 142 certified training and checking provider
- safety critical personnel such as flight dispatchers, load controller and loading supervisor.
