Narrative:
Descended to 2000 ft. Was at 2000 ft until vectored onto approach. Was given approach clearance and turned over to tower. Tower told me to go missed, low altitude alert, back to cape cod approach. Cape said I was at 700 ft. At this time the altimeter on the pilot's side was reading 1700 ft. Started to climb, altimeter stayed at 1700 ft. Readjusted both pilot's and copilot's altimeter to appropriate pressure -- pilots altimeter sprung back to 2000 ft after I turned adjustment. Altimeter replaced after landing.

Title: PLT OF A RECIPROCATING TWIN SMT COMMUTER WAS INSTRUCTED TO GAR DURING AN ILS APCH DUE TO A LOW ALT ALERT BY ATC. THE PLT'S ALTIMETER WAS FOUND TO BE STUCK AND WAS REPLACED AFTER LNDG.
Narrative: DSNDED TO 2000 FT. WAS AT 2000 FT UNTIL VECTORED ONTO APCH. WAS GIVEN APCH CLRNC AND TURNED OVER TO TWR. TWR TOLD ME TO GO MISSED, LOW ALT ALERT, BACK TO CAPE COD APCH. CAPE SAID I WAS AT 700 FT. AT THIS TIME THE ALTIMETER ON THE PLT'S SIDE WAS READING 1700 FT. STARTED TO CLB, ALTIMETER STAYED AT 1700 FT. READJUSTED BOTH PLT'S AND COPLT'S ALTIMETER TO APPROPRIATE PRESSURE -- PLTS ALTIMETER SPRUNG BACK TO 2000 FT AFTER I TURNED ADJUSTMENT. ALTIMETER REPLACED AFTER LNDG.
