EASA 2024-0045

Supersedes but retains requirements of AD 2023-0095, which mandated an inspection of the outside of the fuel filter for bowl cracks and any necessary corrections. Updated AD expands the scope of the inspection of the fuel filter to its inner surface. Prompted by a reported occurrence of external cracks 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. If not detected and corrected, this condition could lead to further cases of fuel filter bowl cracking and, in case of dual—both right- and left-hand sides—filter bowl failure, possibly resulting in in-flight shutdown of both engines.
