PETALING JAYA • The Malaysian airport authorities are searching for the owners of three Boeing 747-200F aircraft left unclaimed at the Kuala Lumpur International Airport, as the mystery deepened with both Malaysia Airlines (MAS) and Air Atlanta Icelandic denying they owned the planes.

Malaysia Airports Holdings had published newspaper advertisements on Monday addressed to the "untraceable owner" of the planes, which may be sold or disposed of if they are not collected within 14 days.

The notice gave the registration numbers as TF-ARM, TF-ARN and TF-ARH, and sought payment from the owners for parking charges and other fees, AFP reported.

Aviation enthusiasts had linked two of the three aircraft to MAS after a search on Airfleets.net found that MASKargo had leased two of the planes from Air Atlanta Icelandic. They claimed the third plane was from Air Atlanta Icelandic, which specialises in leasing aircraft to airlines around the world.

But an MAS official denied it owned the aircraft, saying: "If they were ours, we would have claimed them," The Star reported.

Air Atlanta Icelandic senior vice-president Baldvin M. Hermannsson said the three aircraft were operated by the company until 2010, when they were returned to their owner. "Air Atlanta Icelandic does not have any knowledge of who the current owner of these aircraft is and has nothing to do with these aircraft today," he said.
