Hosed

Engine began running rough in cruise, the pilot diverted and the aircraft was landed without damage. Investigation found the fuel line between the fuel flow transducer and fuel flow divider was loose at the flow divider. Although it seems unlikely, the aircraft operator has to consider the possibility that this fuel line came loose by itself in the five days and 23 hours of flying since the last scheduled inspection....

Key Takeaways:

• Hose failures are a common and critical issue across various aircraft types, affecting fuel, oil, hydraulic, and vacuum systems.
• Failures manifest in diverse ways, including loose connections, leaks, burns from improper routing, material deterioration, and premature splitting, often leading to significant fluid loss or system inoperability.
• These incidents highlight the paramount importance of diligent maintenance, proper installation, careful routing away from heat sources, and thorough pre-flight and scheduled inspections of all aircraft hoses to ensure aviation safety.
