Aircraft Accident/Incident Report
Hagatna, Guam 96910
Saturday, July 15, 2006 18:10 UTC
NTSB Narrative Summary Released at Completion of Accident
The airplane was climbing through 1,500 feet when the engine began to run rough. The pilot tried to smooth it out using the mixture; however, its condition worsened, and it stopped producing power altogether. The pilot could not glide to shore, and he ditched in a nearby bay. Examination of the engine revealed a hole in the top of the case at the number four cylinder. The number four connecting rod fractured and separated. After being in the salt water, the engine had corroded and could not be further disassembled. Moreover, the corrosion obscured the connecting rod fracture faces. Review of the maintenance records found that the engine had flown 1,500 hours past the manufacturer's recommended time between overhaul.
NTSB Probable Cause Narrative
The failure of the number four connecting rod during takeoff-initial climb.
