Analysis

The acft was destroyed during a forced landing. While en route over the San Antonio area the plt noticed a few drops of what he believed to be precipitation on the windshield. Shortly thereafter, it was determined the drops on the windshield were oil. The quantity of oil increased to a point where the windshield was covered. The plt opened the left cockpit window to gain visibility and a landing was attempted on rwy 27 at Stinson municipal. The acft touched down longwith the left wing contacting the rwy. The tower advised the plt to go around. The plt added full pwr, made a left circling turn and the acft contacted the rwy at the intersection of 27 and 32. The plt stated that during the go around oil pressure was noted as zero. Post accident inspection disclosed a cracked brass plated fitting on the prop govenor oil line at the front right side of the eng. The fitting was cracked through 3/4 of its circumference. The manufacturerspart is aluminum and not brass plated.
