Another repair station for Cessna 560 aircraft provided this important discrepancy. “A hydraulic line (P/N 6556000-20) on the left engine was making contact with a fuel line (P/N 3042937-01). This caused chaffing in excess of 20% of the wall thickness on the hydraulic line and 10 to 15% wall thickness on the fuel line. Both lines were replaced with factory new parts. After (their installation) part contact was still being made and required slight adjustments to the bends on the lines to maintain adequate clearance.”

Part Total Time: 900.0 hours.
