What was found
DURING CLIMB, THE NR 1 RADIAL ENGINE FRONT CHIP DETECT LIGHT ILLUMINATED. NO OTHER ABNORMAL INDICATIONS WERE PRESENT. THE DECISION WAS MADE TO JETTISON THE RETARDANT LOAD AND SECURE THE ENGINE. BOTH JETS AND NR 2 RADIAL ENGINE WERE OPERATING NORMALLY. AN EMERGENCY WAS DECLARED AND AN ENGINE OUT LANDING WAS ACCOMPLISHED WITHOUT INCIDENT. UPON INSPECTION OF THE FRONT CHIP DETECTOR, A SMALL PIECE OF FERROUS FUZZ WAS FOUND ON THE DETECTOR. THE ENGINE OIL SYSTEM SCREENS WERE INSPECTED AND NO ADDITIONAL METALLIC CONTAMINATION WAS FOUND. AFTER A SUCCESSFUL GROUND RUN, THE ACFT WAS RETURNED TO SERVICE. THE ACFT SUBSEQUENTLY PERFORMED A 2.6 HOUR FLIGHT TO HOME BASE FOR A PREVIOUSLY SCHEDULED 100 HOUR INSPECTION WITH NO ABNORMAL INDICATIONS. THE ENGINE SCREENS WERE CHECKED AGAIN WITH NO METALLIC CONTAMINATION NOTED.
