Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the next engine shop visit, remove the applicable fuel manifolds from service and replace with parts eligible for installation.
Unsafe condition
This AD was prompted by low-cycle fatigue cracking of the fuel manifold leading to an engine fire. We are issuing this AD to prevent the failure of the fuel manifold. The unsafe condition, if not addressed, could result in failure of the fuel manifold, engine fire, and damage to the airplane.
Affected ADs
None.
