India's Government has launched a search for a new chairman and managing director for state-owned Air India to replace V Thulasidas, who is due to retire at the end of March.

The Ministry of Civil Aviation says on its website that it is inviting applications for a new chairman and managing director to head National Aviation Company of India, which is Air India's parent company.

It wants the new airline head to take over on April 1. Candidates from within the airline are eligible if they are between 45 and 56 years old while those from outside the airline can be no older than 55.

The new chairman and managing director will be responsible for continuing the process of merging Air India with Indian Airlines as well as overseeing preparations for the induction of the enlarged airline in the Star Alliance.

Air India is also looking at placing another large order for new aircraft. In addition, the Government has said it expects to sell part of the national carrier through an initial public offering next year.

Thulasidas has headed Air India since December 2003. He is scheduled to retire on March 31.
