Jettime flight JP546, a Boeing 737-8K5, was approaching Billund, Denmark, when the flight crew carried out a missed approach due to windshear. A flap overspeed occurred during initial climb-out.
The Flap Slat Electronic Unit (FSEU) commanded an automatic flap retraction while the flight crew simultaneously moved the flap handle to position 15°. A flap solenoid valve failed to reset, and the FSEU removed power to the flap drive system when the flaps were retracting at position 13°.
Due to the weather conditions, the flight crew decided to divert to the destination alternate aerodrome: Copenhagen (CPH).
The increased fuel consumption due to the flap 13° non-normal aircraft configuration reduced landing fuel to less than the required minimum final reserve.
The flight crew declared a fuel emergency leading to Air Traffic Control (ATC) priority and direct routing.
The aircraft landed with 119 kilos (kg)/(three minutes) less than the required minimum final reserve fuel of 1,118 kg/(30 minutes).
This serious incident occurred in darkness and under Visual Meteorological Conditions (VMC).
