Here's a behind the scenes look at the control arm that has caused all 111 Ford GT owners to ground their low-flying planes. Ford and supplier Citation Corp. decided to go with a new (at least to U.S. automakers) process of casting that was cheaper, and supposedly stronger. Impurities had tainted the casting process and a weakness was created and found on one of Ford's test GTs. Ford now is using Roush Industries to create a forged replacement for all eight control arms, but ramp up is slow, and only a limited amount of GTs have been built since the recall. Existing GTs won't be repaired and back on the road until the first week of March. Hero to zero with one crack.
