Cessna Mandatory Service Bulletin SEL-28-09 - Fuel Pump
Some fuel pumps have been identified to have incorrectly installed seal and possible FOD that can cause pump vanes to stick or not pump correctly and must be replaced. A pump with an incorrectly installed seal does not meet engineering design and a pump with FOD can make a grinding noise during operation or fail to pump fuel. During a flight situation where the auxiliary electric fuel pump is required to provide fuel to the engine, a pump that is not pumping correctly or stops pumping fuel, can cause a total loss of engine power. Please call or email LGM if there are any questions concerning this SB. Thanks.
