ST Engineering said its aerospace arm has clinched about S$320 million worth of new maintenance contracts in the fourth quarter of 2010.

Ranging from three to 12 months, these contracts will be carried out at ST Aerospace's facilities in the Americas, Asia-Pacific and Europe.

This is in addition to the maintenance-by-the-hour contract awarded by China Airlines announced in November last year.

In the October to December quarter, ST Aerospace redelivered 103 aircraft to various customers, for airframe related maintenance and modification work.

During the period, ST Aerospace also added a two-bay wide-body hangar to its existing U.S. facility in San Antonio, Texas, bolstering its global network of MRO facilities.

Commissioned in December last year, the new hangar will serve customers operating in and flying into the U.S.

Besides capacity expansion, ST Aerospace has also been growing its Boeing 757-200 aircraft conversion capability offerings.

It received two Supplemental Type Certificates for its Boeing 757-200 Passenger-to-Freighter conversion programme from the Civil Aviation Administration of China (CAAC) and Transport Canada.

Its Component Total Support business clinched new component contracts, including contracts for avionics and mechanical component maintenance, aerostructure and landing gear repair and overhaul.

The Engine Total Support business also secured new engine maintenance contracts, which include on-wing maintenance, off-wing maintenance, technical management and asset management on various engines types.

These contracts will be carried out at ST Aerospace's Singapore facility over the next three months on a time-and-material basis.
