(n) Do a visual inspection of the fuel nozzle wear sleeves.
NOTE: On some fuel nozzle assemblies, the wear sleeve does
____ not have a continuous weld to attach it to the fuel nozzle. Such fuel nozzle wear sleeves have four individual weld spots. This is a 4-interrupted weld design.
1) If the wear sleeve is dislodged (not attached), it is not serviceable. a) Replace the fuel nozzle and do a borescope inspection
for downstream damage (AMM 72-00-00/601), or see the maximum service extension (AMM 72-00-00/601, Combustion Chamber or HPT Nozzle Guide Vanes - Inspection).
