A BE36TC descends below MEA to avoid WX. Pilot never gets clearance from ZLC due to stuck microphone on frequency and loss of #2 communication radio.

Narrative:
On IFR flight plan at 16000 ft (MEA), was necessary to descend to 14500 ft for WX avoidance. Unable to cancel IFR due to lost communication #2 due to stuck microphone on frequency. Communication lost for approximately 10 mins. Maintained visual terrain separation and VFR until able to recontact ZLC (different frequency) and re- establish IFR. Since we descended below MEA (10000 ft), unlikely to conflict with other IFR traffic. No emergency, no evasive action. Communication re-established uneventfully.

Narrative: ON IFR FLT PLAN AT 16000 FT (MEA), WAS NECESSARY TO DSND TO 14500 FT FOR WX AVOIDANCE. UNABLE TO CANCEL IFR DUE TO LOST COM #2 DUE TO STUCK MIKE ON FREQ. COM LOST FOR APPROX 10 MINS. MAINTAINED VISUAL TERRAIN SEPARATION AND VFR UNTIL ABLE TO RECONTACT ZLC (DIFFERENT FREQ) AND RE- ESTABLISH IFR. SINCE WE DSNDED BELOW MEA (10000 FT), UNLIKELY TO CONFLICT WITH OTHER IFR TFC. NO EMER, NO EVASIVE ACTION. COM RE-ESTABLISHED UNEVENTFULLY.
