Required Actions
Dye-penetrant inspect the tip cap P/N 709-0103-29-109 for cracks on the tip cap leading edge at the welded bead (joint line of shells), and remove the magnifying glass inspection that was specified in the original service information. If a crack is found, replace the MRB before further flight. For MRBs with a S/N that has a prefix of either 'EM-' or 'A5-', except an MRB with a tip cap P/N 709-0103-29-109 installed, tap inspect each tip cap for bonding separation in specified areas, tap inspect for bonding separation in the tip cap to blade bond area, visually inspect the upper and lower sides of each blade tip cap for swelling or deformation, and dye-penetrant inspect the tip cap leading edge along the welded joint line of the upper and lower tip cap skin shells for a crack. If there is any swelling, deformation, or crack, or bonding separation that exceeds allowable limits, remove the blade from service before further flight; if there is no swelling, deformation or crack, or if bonding separation does not exceed allowable limits, continue the inspections.
