CASA EX12/24 – Transitional Training and Checking Requirements for Crew Members in Part 121 Operations – Exemption Instrument 2024 (No. 1)

What this legislation does:

This instrument gives airlines and their flight crew (pilots, flight engineers) and cabin crew (flight attendants) a temporary break from certain new training and checking requirements when moving from old aviation rules to new ones.

Who it affects:

• Airlines operating larger aircraft (more than 9 passenger seats or over 8,618 kg take-off weight) under Part 121 of the aviation safety rules
• Flight crew members (pilots and flight engineers) working for these airlines
• Cabin crew members (flight attendants) working for these airlines

Why it matters:

Australia updated its aviation safety rules on 2 December 2021, introducing new training and checking requirements under "Part 121" for commercial air transport. However, many crew members had already completed training under the old system (through organisations called T&COs — Training and Checking Organisations).

Instead, their old training counts for a transitional period.

How it works:

The instrument contains a large table (Table 1) with 24 different scenarios. For each type of training or check required under the new rules (like proficiency checks, line checks, emergency training), the table specifies:
