FAA Proposes AD on Gulfstream GV and GV-SP Fuel Boost Pumps

The FAA proposes to supersede AD 2013-22-19, which applies to all Gulfstream GVs and GV-SPs. It requires determining if fuel boost pumps with a certain part number are installed, replacing them and revising the airplane maintenance program to include revised instructions for continued airworthiness. The FAA has now determined the AD must be revised to include new service information to require revising the airplane maintenance program to include a fuel-leak check of the fuel boost pumps using the new service information. The proposed AD is to prevent fuel leakage in combination with a capacitor clearance issue, which could result in an uncontrolled fire in the wheel well.
