## Discrepancy

DURING FIRST 100 HOUR INSPECTION,  TIMING WAS CHECKED AND FOUND TO BE FOUR DEGREES OFF OF CORRECT TIMING. THIS HAS BEEN NOTED ON ALL NEW AIRCRAFT AND OVERHAULED ENGINES FROM MFG OVER THE LAST EIGHT TO TEN ENGINES & AIRCRAFT. TIMING WAS RESET TO PROPER SPECIFATIONS.  NO PROBLEMS WERE NOTED IN ENGINE PERFORMANCE PRIOR TO OR AFTER RETIMING THE MAGS.
