Did you actually load the project into DevMode? Decompiled with ADE and re-loaded there are multiple required jetways missing, multiple Taxi Paths with invalid widths, Your model library objects have some identical objects and some with invalid texture sizes. A couple of your objects are just odd (perhaps with orientation or scaling problems). ADE shows you have some duplicate parking spots (not allowed), open or orphaned nodes... I suspect the airport radius needs to be set larger to perhaps 6000M.
Almost any of these faults could cause a CTD.
I realize this would be upsetting, but your best course is to fix all these problems. Fix the models, fix the textures, fix the airport issues with ADE.
