Summary
Requires a one-time inspection of the fuel filters and, depending on findings, replacement with a serviceable part(s). Prompted by a reported occurrence where cracks were found on the right-hand-side fuel filter bowl following
an engine flameout. Subsequent investigation determined that the cracking may have been initiated by over-torquing of the stirrup thumbscrew during replacement of the fuel filter cartridge. This condition, if not detected and corrected, could lead to further cases of fuel filter bowl cracking and, in case of dual—both right- and left-hand sides—filter bowl failure, could possibly result in in-flight shutdown of both engines.
