Narrative:

During approach to land at fll airport, the landing gear failed to extend. During the missed approach, while dealing with a landing gear emergency, we were cleared to 2000 ft, but I climbed to 2500 ft, due to being distraction while dealing with the landing gear failure. This emergency requires one crew member to leave the flight deck to manually extend the landing gear. I was flying by hand and reading the checklist to ensure everything was completed in order. The autoplt was not an option due to the yawing of the aircraft to induce air loads to lock main landing gear in the down position. Maintaining 300 ft within my assigned altitude was difficult at best.
