OXFORD — The aircraft-refurbishing company Oxford Aviation says it plans to hire another 20 workers over the next two months as business picks up.

Oxford Aviation currently employs about 45 people. Company official Diana Allen tells the Sun Journal that most of the jobs are expected to be long-term positions.

Allen said the clients are now moving forward with work that had been delayed because of the tough economy in the U.S. and around the world. Almost all of the company’s customers come from outside Maine.

Oxford Aviation is based in a 40,000-square-foot facility at the Oxford County Regional Airport.
