Narrative:

During climb out we were given heading of 360 and an altitude of 4;000 ft MSL. Upon selecting gear up; we experienced a malfunction with the gear position resulting in a pitot heat failure. We were in icing conditions and with the chance of our pitot tube icing up; I initiated a climb rate that would get us out of icing conditions as soon as possible. This resulted in an altitude deviation of 1;400 ft which we corrected immediately upon selecting alternate heat for the pitot tubes and began to trouble shoot the gear problem; which we eventually fixed. ATC did ask us our altitude as we did not have time to call them about our situation. We told them that we were leveling at 4;000 ft at which time he said that he showed us at 5;400 ft and gave us a further climb. There were no traffic issues that we were aware of and ATC did not advise us of any. I understand that anytime I have to deviate from an ATC assignment; I should advise them as soon as possible but under the circumstances time did not allow for a call until we were in safe flight conditions.

Title: IAI1123 Captain; shortly after takeoff into icing conditions; experienced landing gear issues and a pitot heat failure. An immediate climb was initiated out of icing conditions but exceeding initial altitude assignment without advising ATC. The gear and pitot heat issues are resolved.
