Cabin safety regulations explained

Some new Civil Aviation Safety Regulations 1998 (CASR) replace or change some Civil Aviation Regulations 1998 (CAR) and Civil Aviation Orders (CAO) that covered cabin safety.

Find out more about the flight operations regulations transition.

Effects of changing rules on cabin safety

Most rules for cabin safety subject matter are now in the group of CASR called the flight operations regulations. These regulations replace many of the CAR that previously covered cabin safety.

For example, requirements for emergency and life-saving equipment from CAR 253 are now in Part 121, 133 and 135 of CASR – depending on your operations.

The CASR introduced in 2021 include:

Manual of Standards replace Civil Aviation Orders

All of the CAO related to the CAR have now been repealed. Instead, detailed technical material and requirements that complement the CASR are found in the relevant Manual of Standards (MOS).

Not every CASR Part has a corresponding MOS, for example there is no MOS for Part 119. Not every regulation refers to a MOS. It occurs where the regulation is broad and further detail is required.

When the flight operations CASR became effective, relevant cabin safety content moved from CAO to MOS.

For example, you can find standards for emergency and life-saving equipment:

  • for larger aeroplanes in chapter 11 of the Part 121 MOS (Division 9 to 12)
  • for rotorcraft in chapter 11 of the Part 133 MOS (Division 9 to 12)
  • for smaller aeroplanes in chapter 11 of the Part 135 MOS (Division 9 to 12).

The relevant MOS for flight operations are:
