Factual narrative

DURING TAKEOFF AT ABOUT 50 FT AGL & 4,000 FT DOWN RWY 4R, THE RIGHT ENG LOST POWER. ACCORDING TO THE PLT, HIS AIRSPEED WAS 105 MPH & THE RIGHT ENG 'POPPED' BEFORE IT LOST POWER. HE ALSO STATED THAT POWER ON THE LEFT ENG DETERIORATED AFTER THE THE RIGHT PROP WAS FEATHERED. THE ACFT WENT INTO A RIGHT BANK & THE PLT MAINTAINED CONTROL OF THE ACFT UNTIL IMPACT WITH THE WATER. EXAMINATION OF THE RIGHT ENG REVEALED THAT THE RIGHT MAGNETO, AMERICAN BOSCH SB9RU-3, SER #B88470, WAS NOT TIMED CORRECTLY. DISASSEMBLY OF THE MAGNETO REVEALED THAT ALL EXCEPT 11 DISTRIBUTOR GEAR TEETH WERE STRIPPED OFF. AT THE TIME OF THE POWER LOSS OF THE RIGHT ENG, ABOUT 5,000 FT OF RWY WAS REMAINING.
