706 may not be flying for another six months (c check,
certification,winter,etc),stopping the engine lease
would save money.Fuel for engine runs would also be one
expense less.Three days ago the acft APU was started,
electric and hydraulic power applied and flight controls
operated.The acft doors were opened to air it out and
it was moved a little to keep the tires from flattening.
Kalitta does this every week,and you dont'need engines,
which can be leased back later.
