The C checks are phase checks , by time of the aircraft in service, when you get to the point where the whole interior is being gutted, and all the flight controls come off, that is contracted out. We do a few avionics mods when engineering calls for it. With the classics gone, we do not have all the structure work that we had. Like we can have a -700 come in for just the main gear changes, plus a few other task cards.Could you define your D check? Our 737 "Heavy C" is cabin stripped Structure inspected and repaired, Wings check all flight controls inspected and overhauled, Fuselage Inspected with an ADL, Stabilizer, and Verticle also inspected etc..and put back together and several ECO's for systems and Avionics.
