AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators and training centers should emphasize verifying adequate fuel quantity on the side with the operating BOOST PUMP when the CROSSFEED valve is open during a BOOST PUMP failure. Pilots must be trained to close the CROSSFEED valve to allow the HP Fuel Pump to suction-feed fuel from the side with the failed BOOST PUMP. Continuous fuel monitoring and management are essential to avoid fuel starvation and engine failure.
Summary
The Safety Alert for Operators SAFO 18001 provides important safety information regarding Textron (Beech) King Air 90-Series airplanes. It addresses the risk of dual engine failure caused by improper fuel management during BOOST PUMP failure and CROSSFEED valve operation. The document highlights operational considerations to prevent engine flameout related to fuel starvation and imbalance.
What changed
SAFO 18001 introduces guidance on managing BOOST PUMP failure and CROSSFEED valve operation in King Air 90-Series airplanes. It clarifies the risks of dual engine failure if the CROSSFEED valve is left open without proper fuel monitoring and emphasizes the correct emergency procedures to mitigate this risk.
Why it matters
This information is critical for pilots, operators, and training organizations to prevent dual engine flameout due to fuel mismanagement during BOOST PUMP failure scenarios. Proper understanding and training on CROSSFEED valve operation can enhance flight safety and reduce the risk of in-flight engine shutdowns. It also supports compliance with FAA safety recommendations and operational best practices.
