IIRC, the original design was twin-engine.  The original engine maufacturer
(R-R?) didn't have an engine in the correct thrust class ready in time, so BAe
had to scramble and change to the four-engine Avco-Lycoming powered design.

Two other asides;  they were so noisy, that PSA had additional soundproofing
added.  The ones I flew were still noisy and personally, if I were flight or
cabin crew on one I would probably wear foam earplugs.

The other aside is that they don't have reverse thrust, only wheel brakes and a
speedbrake in the tailcone.  Air Wisconsin had lots of problems operating into
short, slick runways in winter.
