I assume you meen FAA.

A problem with the plane is a problem with the FAA, because the FAA signed off on the plane. Seperatly from figuring out the technical failures that led to the crashes, they need to figure out the regulatory failures that led to a plane with such failures being approved.

Boeing is publicly traded and important to the US. Seems the FAA might have some incentive (not necessarily directly financial) to make sure Boeing remains competitive in the market vs. Airbus.
