Explanatory Statement
Civil Aviation Regulations 1988
Direction — number of cabin attendants
Legislation
Subsection 98 (1) of the Civil Aviation Act 1988 (the Act) provides that the Governor-General may make regulations for the Act and in the interests of the safety of air navigation.
Under regulation 208 of the Civil Aviation Regulations 1988 (CAR 1988), CASA may give directions as to the operating crew required to be carried on an aircraft having regard to the safety of air navigation. Subparagraph 6.1 (b) of Civil Aviation Order 20.16.3 (CAO 20.16.3) was made under regulation 208 and provides, among other things, that aircraft carrying more than 36 and not more than 216 passengers must carry a cabin attendant for each unit of 36 passengers or part of that number.
The requirements in subparagraph 6.1 (b) of CAO 20.16.3 have remained in the same form since 1960 and as such represent a 51 year gap since a reassessment of cabin attendant numbers against a criterion of allowable seating rather than passenger numbers.
Airbus certification of the aircraft relates to the design of the floor plan and the seating configuration in relation to the location of exits. CASA does not call for a re‑evaluation of the aircraft design; instead, CASA accepts the design criterion. CASA does require operators to demonstrate the safety procedures that are specific to the operator, which are evaluated, thus there is a distinction between the certification criterion and an operator-imposed safety procedure which may, or may not, enhance the evacuation of the aircraft in an emergency evacuation. CASA has increased passenger awareness and capability for passengers seated at self-help exit rows in a manner equivalent to, or better than, that achieved when the Airbus A320 satisfied the Joint Aviation Authorities (Europe), now European Aviation Safety Agency, standards.
CASA is satisfied that the evacuation of a full complement of passengers for the Airbus A320 aircraft is able to be achieved in a time of 90 seconds. CASA is satisfied that the evacuation procedures adopted by Tiger Airways Australia Pty Limited (the operator) to support their application to operate with the certification criterion of 4 cabin attendants have been demonstrated successfully. The maximum permitted time of 90 seconds is set out as a condition in Schedule 1 of the instrument.
The other conditions include a requirement that the briefing of passengers in self-help exit rows must be as approved by CASA and in the manner set out in the operator’s operations manual. The operator has incorporated procedures for the briefing of passengers seated at self-help exit rows as part of the pre-departure passenger safety briefing, taking into account the conclusions of the Cranfield University research. The operator has incorporated pre-warned emergency briefings for passengers seated in Type I and III exit rows based on the verbal briefing criteria specified in the Cranfield University research. The revised briefings are acceptable to CASA and are seen as a safety enhancement.
Legislative Instruments Act
Under subparagraph 6 (d) (i) of the Legislative Instruments Act 2003 (the LIA), an instrument is a legislative instrument for section 5 of the LIA if it is declared to be a disallowable instrument under legislation in force before the commencement of the LIA. Under regulation 5A of CAR 1988, if CASA has issued a Civil Aviation Order (CAO), and CASA later issues a direction that affects the operation of the CAO, the later document is declared to be a disallowable instrument. The instrument affects the operation of subparagraph 6.1 (b) of CAO 20.16.3. As a legislative instrument, it is subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LIA.
Consultation
This instrument replaces instrument CASA 451/10 which stopped having effect at the end of July 2011. CASA consulted both internally and with the operator before issuing that instrument. The instrument is similar to instruments, issued to other operators, that have been the subject of consultation within CASA and with other bodies.
Senate Regulations and Ordinances Committee concerns
This direction provides for the operator to meet a new standard for cabin crew numbers. The new standard differs from that currently promulgated in CAO 20.16.3, but it is considered to be a safe standard, consistent with international safety standards and practice.
The direction is 1 of a number of such instruments issued to, or renewed for, several operators pending CASA’s development of considered amendments to bring CAO 20.16.3 into line with new internationally recognised standards for cabin crew ratios (at least 1 cabin crew attendant for every 50 passenger seats, and 1 attendant for any incomplete part of that number).
The development and preparation of suitable CAO amendments is a more intensive and involved process than the evaluation and consideration of directions for a particular named operator. While such evaluation and consideration for an individual operator is itself detailed, and guided by the requirements of safety and prudence, it has not required extensive consultation with the broader industry.
Pending the finalisation of the project team’s work on the CAO, it is essentially unavoidable that CASA will issue or renew individual directions to operators on the same basis as has previously been done. The instrument is issued for a period of approximately 3 months only, pending resolution of the wider issues involved.
The instrument commences on the day after registration and stops having effect at the end of December 2011.
The direction has been issued by a delegate of CASA under subregulation 11.260 (1) of the Civil Aviation Safety Regulations 1998.
