The Airworthiness Unit was first established in 1972, under the Flight Operations Division to regulate aircraft maintenance activities. The Civil Aviation Authority, United Kingdom (CAAUK) was contracted to manage the unit. CAAUK airworthiness officers were positioned in Malaysia and the British Airworthiness Standards were adopted. Expansion of job functions and responsibilities resulted in this unit being upgraded to a Divisionin 1992. The CAAUK officers were gradually replaced and since 1999 the Airworthiness Division is fully manned by Malaysians. The UKCAA contract was changed to a consultancy service. The Airworthiness Division had subsequently evolved to become a Sector in 2007 with further expansion of job functions and responsibilities.
The Airworthiness Division carries the regulatory function in respect of airworthiness through the establishment of standards, recommended practices and guidelines, and their enforcement as required by the Civil Aviation Act [CAA] 1969
