## Discrepancy

FOLLOWING A RECENT SIMILAR EVENT, THE SAME CREW MEMBER SMELLED FUEL IN FLIGHT ONCE THE AIRCRAFT REACHED APPROXIMATELY 100 KIAS STRAIGHT AND LEVEL. THIS TIME THE SMELL APPEARED TO BE MUCH STRONGER. THE PILOT IMMEDIATELY RETURNED TO BASE AND CONTACTED THE MECHANIC. HIS SUBSEQUENT INSPECTION REVEALED A BAD SEAL ON THE FUEL CAP. ANOTHER ONE WAS ORDERED AND REPLACED. THE DISCREPANCY WAS THEN SIGNED OFF, AND THE AIRCRAFT RETURNED TO SERVICE.
