Background: This Directive has been issued to address reports of fuel filter by-pass valves being found jammed during scheduled fuel filter maintenance.

The revision, in part, provides a terminating action. The requirements of this Directive are no longer applicable to helicopters incorporating Mod. 0726087 (SB 28-00-38).

Amendment 3 was raised to delete the AS332L2 model and to add a fuel filter part number and became effective on 28 December 2000.

Amendment 2 was raised to include an additional P/N filter and to reference R2 of the manufacturer’s service telex and became effective on 13 July 2000.

Amendment 1 was raised to list affected fuel filters by part number and became effective 25 February 1999.
