Analysis

Moments after the DC-3 took off, the twr ctlr noted the l eng was torching & asked the flt if it was 'having a problem.'the crew replied 'affirmative,' then the ctlr clrd the flt to lnd on any rwy. The acft began turning left at the end of the rwy & contd turning at low alt until it struck utility poles & crashed thru a warehouse roof about 2 mi fm the arpt.a witness rprtd the acft was at an alt of aprx 100 to 150 ft AGL, the l prop was feathered & the r eng was at full pwr. An exam of the l eng disclosed the #14 cylinder was missing a spark plug fm the front spark plug hole. The spark plug lead & 'b' nut were attached to the ignition harness, but no plug was attached to the lead. The spark plug hole & b-nut threads were undamaged. A white deposit was fnd inside the cylinder spark plug threads & outside the cylinder, adjacent to the hole. The deposit was identified to contain high concentrations of lead & bromine, most likely formed from exhaust gases & fuel during cylinder operation. A company mechanic rprtdly worked on the plugs on the previous day.
