The single shank design can contain better air and lower metals. To release, the air coming out of the compressor enters through the root blade and exits through the holes at the leading edge, tip, and trailing edges. Failure or damage blade HPT Rotor for engine CFM56-7B affects economic operations so use the MSG 3 analysis method. Which aims to analyze a risk of failure. The damage found on the high pressure turbine rotor blade is a hole in the front wall in area A. With a hole dimension of 0.078 inches radially x 0.054 inches axially 1981.2 mm radially x 1371.6 mm axially. Based on AMM Boeing 737 600 700 800 900 maintenance decisions on the HPT Rotor blade components are still within the limits of limitation and inspect again after 100 cycles. So according to the method MSG 3 there are no additional operations to replace components.} }
