Carefully inspect the fuel nozzle lines for: a. Chafing - where lines have rubbed together, rubbed other engines parts or have been rubbed by other items. b. Kinks or sharp bends c. Fuel stains at the ferrules (lines must be replaced with airworthy components if any of the above discrepancies are found) 2.
