Narrative:
Flying in IMC conditions on an IFR flight plan the aircraft took a lightning strike on the wingtip on the port side. No abnormalities were detected at the time of the strike. Twenty minutes later an unusual smell was detected in the cabin and then white smoke followed which appeared to be originating from underneath the panel on the co-pilot side. An emergency was declared and smoke in the cockpit was reported to the controller. An emergency descent was performed from 15;000 ft to pattern altitude with the consideration that a cabin fire was to follow. An emergency landing was made without incident.
