Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2013-22- 19, which applies to all Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. AD 2013-22-19 currently requires inspecting to determine if fuel boost pumps having a certain part number are installed, replacing the fuel boost pumps having a certain part number, and revising the airplane maintenance program to include revised instructions for continued airworthiness. Since we issued AD 2013-22- 19, we have determined that the maintenance or inspection program, as applicable, must be revised to include new service information. This proposed AD would continue to require revising the airplane maintenance program to include a fuel leak check of the fuel boost pumps, using new service information. We are proposing this AD to prevent fuel leakage in combination with a capacitor clearance issue, which could result in an uncontrolled fire in the wheel well.
