Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During flt, the plt noted a progressive loss of eng power. The application of carburetor heat had no effect. Subsequently, a loud noise occurred & the plt shut down the eng. During a forced landing the nose gear collapsed & the acft nosed over. An exam revealed that the #4 connecting rod had failed. Internal damage was found to have occurred due to lack of lubrication. A further exam revealed that the diaphragm of an oil pressure switch had ruptured & allowed depletion of the eng oil supply. The switch, datcon pn 40558-1, was installed on 1/1/74, directly into the eng block (tapped oil gallery hole) & was used in connection with electrical action of the acft's hourmeter. Datcon service bulletin #1, subject: hazardous installation of oil pressure switches, dated 1/2/75, not complied with.
