Delta Airlines grounded their MD-80 fleet yesterday. They’re taking another look at their wiring . This action was driven bythe same FAA audit which led American to ground and reinspect their MD-80’s. A statement by Delta said that the wiring of the auxiliary hydraulic system was the culprit.
The Aux Hyd system runs while the aircraft is at the gate. That way, you can flush the toilet and stuff. It is not a safety of flight issue.
The FAA announced that it will release its findings on its month long audit of the airline industry’s maintenance documentation.
