San Diego-based engine supplier Avioserv has been selected by Southwest Airlines to support the airline in its retirement of its Boeing 737 Classic aircraft.
Avioserv will help Southwest control overhaul costs for its CFM International CFM56-3 engines, utilise consignment material for engine overhauls and help market excess inventory for decommissioned engines.
Southwest has said it plans to decide in a few months on the retirement rate of its 737 Classics, which has put cost pressure on the airline as maintenance costs go up on the ageing fleet.
According to Southwest's annual report for 2011, the airline has 161 737-300s and 25 737-500s in its fleet. The average age of the -300s is 20 years while the -500s are 21 years old on average.
Avioserv deals in the supply and sale of serviceable aircraft engines, as well as the sale, lease and exchange of engine parts.
