I wouldn't put faith in the FAA to be beyond political influence and crack down on an American manufacturer quickly.
Lauda Air flight 004 [0] crashed in 1991 after inadvertent thrust reverser deployment mid-flight, which were not secured with positive locks since Boeing deemed this to be impossible. The FAA accepted Boeing's tests at face value. Regardless, Boeing insisted this would be a survivable event - it wasn't until Niki Lauda (airline's founder) insisted Boeing issue a statement to the contrary or to perform a test flight with him and two pilots attempting a deliberate reverse thrust deployment mid-flight. Boeing relented and acknowledged the defect.
The more groups looking at aviation safety, the better.
