Narrative
On February 17, 2016, a Boeing 737-800 was involved in an incident during the climb phase after takeoff. The left center tank fuel pump low pressure warning light illuminated. The flight crew executed the appropriate checklist procedures for the low pressure indication and continued the flight to the intended destination. Upon landing, the airline's maintenance control center (MCC) was notified of the anomaly. Maintenance personnel permitted the aircraft to return to service under MEL 28.2.B, and the airplane was ferried to the main maintenance base for further investigation.
Cause
The low pressure indication was caused by a blown fuse inside the fuel pump.
Aftermath
At the maintenance base, technicians inspected the center tank fuel pump system. Tests revealed that the pump's internal fuse had failed. The fuse was replaced, and the MEL restriction was removed. The aircraft was subsequently returned to unrestricted service. No safety recommendations were issued by the investigating body.
