Fuel pump issues
Pump is used widely in our daily life, but not everything is perfect, sometimes we will run into some problems. These days some agencies are investigating the performance of pump. such as sustainability, reliability, stability and working efficiency.
Investigators plan further examination of the fuel pump on a small plane that crashed near Portland International Jetport in Maine, killing two people.
A preliminary report by the National Transportation Safety Board noted this week that tests of the crash-damaged Yak-52 pointed toward problems with the fuel pump.
The report says there appeared to be corrosion inside the fuel pump bypass valve and fuel inlet line. A stuck bypass valve could cause the engine to become starved for fuel.
Pilot Mark Haskell of Brunswick was undergoing biannual certification and had a flight instructor with him when the Soviet training aircraft crashed shortly after takeoff on June 17. The propeller was not turning on impact, indicating that the engine had failed.
So we should fortify our examination of fuel pump when it is produced. You know, these pumps are used in heavy industry, so it should be produced perfectly.
