Project CS 99/03 - Additional Airworthiness Requirements

Topic code: 
Aircraft Registration, Marking and Certification
Project status: 
Closed

Closure notes

Project closed 13 December 2010.

CASR Part 90 and its Manual of Standards (MOS) came into effect 1 December 2010.

Part 90 can be found in volume 2 of the CASR. Recent amendments to this Part may be listed in the Unincorporated Amendments.

View the Part 90 Manual of Standards.

Issue

Part 90 will prescribe certain additional airworthiness requirements to which aircraft owners/operators are responsible for ensuring compliance prior to operations.

In developing CASR Part 90 CASA seeks to achieve the objective to provide standards that are clear, concise and unambiguous. CASA also seeks to ensure those standards are:

  • focused on safety, adopting a systems approach where appropriate
  • consistent with Australia’s international obligations
  • harmonised with international standards, unless unique Australian circumstances require otherwise
  • cost-effective
  • enforceable.

Objective

CASR Part 90 will specify the airworthiness standards, additional to the original type certification requirements, that owners/operators are responsible for ensuring compliance prior to operations.

This new Part will replace the system of general Airworthiness Directives (AD) that retroactively make new airworthiness standards applicable to all existing aircraft. Part 90 is considered to be a more appropriate vehicle than ADs for promulgating retroactive airworthiness standards.

Part 90 will consolidate and retain existing requirements from current General ADs in CAO Part 105 with minimal change.

Status

This project was approved February 1999.
