Narrative:

While being vectored on approach; left engine control fault light illuminated. Informed ATC of indication problem followed the checklist and engine fault will not reset. Then discovered that the left engine was stuck at 67% N1. After 3 minutes; right engine control fault light illuminated; following the checklist; engine fault will not reset. Right engine N1 was missing from mfd and was showing normal thrust on emergency standby indicator. Requested ATC to switch from short runway 22 to runway 30L as it was longer and asked co pilot to shut down left engine on flare in order to maintain control of aircraft on the ground. Did not elect to shut down left engine inflight as the right one was also operating with fault. At approximately 60 knots; I took control of aircraft and taxied it with one engine to the FBO.
