Ouch, that hurts. I fly a B-100. Its may be loud and ugly- but its does great of fuel burn and holds a lot of gas. Its also a workhorse. We can have execs in there one day and haul tredmills the next. Not to mention crain transmitions. But those garretts sure are noise makers.
The reason line guys hate the B-100 so much is the exhaust blasts ya while you're trying unhook the GPU hookup under the nacelle. Tell the pilot to throw that right engine in BETA and all that bad news will go forward.
