Beleive you're talking about the Fokker-VFW 614 19 seat regional jet. It had two MTU turbines mounted over the wing. IIRC the reason was "better shielding of overflight fan noise by the wing". I remember being just about knocked out of bed when staying at BAE's visitors accomodation at Filton when one did a run-up outside - and you thought a 1-11 was noisy! A similar layout is currently being used by Honda on the Hondajet.
