Analysis
Shortly after takeoff, the acft's climb performance bgn to deteriorate & the r eng started to overheat. Subsequently, the r eng was feathered & the crew attempted to return to the arpt. The radio transmitter bcm unintelligible, so the tower psnl cleared the acft to land on rwy 10 & asked the crew to key their mike twice, if they understood. The mike waskeyed twice. The acft entered a r dwnwnd for rwy 10 at a very low alt. According to witnesses, the acft went into a steep bank as it was turning onto a base leg over water, the r wing tip hit the water & the acft cartwheeled & crashed. The coplt rprtd that after feathering the r eng, the VMC of 84 KTS was maintained; however, he believed the acft stalledjust prior to impact. A teardown of the r eng revealed the edge of the #8 piston & its piston rings had failed. Metal filings were found in the oil & the oil pump was scored. There was evidence of oil starvation to the crankshaft journal,as well as piston slap associated with the ring failure.
