Part 135 of CASR Australian air transport operations - smaller aeroplanes

Rule status

Current

Part 135 of the Civil Aviation Safety Regulations (CASR) covers the air transport rules for smaller aeroplanes.

The term ‘air transport’ replaces both charter, regular public transport (RPT) and air ambulance when conducted for hire or reward. It adds the transport of medical supplies or medical personnel for hire or reward as well.

If you are operating under these rules, you should also read Part 119 which deals with the general certification and management for air transport operations.

If you conduct other operations, such as rotorcraft air transport, you need to comply with other CASR flight operations parts.

Visit our flight operations transition section to find out more.

Who it affects

Part 135 of CASR applies to air transport operations in aeroplanes with:

  • a maximum operational passenger seating capacity of nine
  • a maximum take-off weight (MTOW) of 8,618 kg or less.

Subpart 121.Z applies if you are operating single-engine aeroplanes with a seating capacity of more than 9 seats. You must also comply with most of Part 135.

Some operators may be able to operate an aeroplane with up to 13 seats if they are already conducting these operations and meet the requirements.

All operators and pilots also need to comply with Part 91 of CASRGeneral operating and flight rules. Keep in mind Part 135 may add to or turn off some Part 91 requirements – either completely or partially.

This document is intended to assist persons who will conduct air transport operations under Part 135 or Subpart 121.Z of CASR to prioritise their actions to transition to the new flight operations regulations.

The purpose of this document is to present and summarise the key elements of these determinations in plainer English, as the legal instruments themselves are relatively lengthy, repetitive and complex.

Impact of new flight operations regulations on flight crew licencing exams. The introduction of the new flight operations regulations on 2 December 2021 will mean changes to the various flight crew licensing (FCL) theory exams.

This Guide assists operators using the associated CASR Flight Operations Sample Exposition / Operations Manual template in Word format. The contents in this Guide, the associated Word, and MAAT templates has been structured in a logical order and provides clear references to the legislative requirements.

Use this form to submit, and apply for an approval of, the Training and Checking System section of an exposition or operations manual as part of the transition to Parts 119, 121, 133, 135, and 138 of the CASR.
