## Discrepancy

THE AIRCRAFT FUEL QUANTITY READING DECREASED RAPIDLY IN FLIGHT ON THE VEMD CAUSING THE PILOT TO PERFORM A PRECAUTIONARY LANDING. THE CAUSE WAS THE AFT HOSE FROM THE FUEL SYSTEM NORMALLY PROTRUDING FROM THE BELLY OF THE AIRCRAFT DIRECTLY BELOW THE FUEL CELL WAS CAUGHT AT AN ANGLE IN THE BELLY PANEL. THIS ALLOWED NO VENTING TO TAKE PLACE AND CAUSED AN INTERNAL SUCTION WHICH ADVERSELY AFFECTED THE INDICATION OF FUEL QUANTITY. WHEN FREED TO ITS NORMAL OPERATING POSITION, THE HOSE SUCKED AIR FOR APPROXIMATELY 30 SECONDS. THE VEMD THEN DISPLAYED PROPER FUEL QUANTITY.
