Analysis

While taxiing to takeoff, smoke was noted in the cockpit area, shortly after the plt activated the heater ignition switch. The plt immediately stopped & secured the acft & assisted the passengers in deplaning. An exam of the janitrol heater, model B4050, revealed the aft section of the tube assembly had cracked; the inner tube assembly was corroded & a b-nut was 'finger tight.' Also, there was fire damage in the nose section of the acft, near the heater. The director of maintenance said that AD-82-07-03, inspection of the heater tube assembly, was complied with on 11/14/83.
