2021-12 · NASA ASRS report 1865666
Flight Crew reported that during climbout in turbulent conditions; the left engine L ENG VAL EICAS Light; and the ENG VAL Light above the fuel cutout switch illuminated. The Flight Crew elected to perform an air turn back and overweight landing.
Shortly after TO; Tower inform[s] all traffic on the frequency that they could expect moderate to severe turbulence at 15;000 feet [to] 17;000 feet. We climbed through this and verified it was every bit of mod turbulence and reported as such. Shortly after this turbulence; the L ENG (Engine) VAL EICAS (Engine Indicating and Crew Alerting System) Light; and the ENG VAL Light above the fuel cutout switch illuminated. Engine indications were normal. After running the appropriate checklist which had us confirm the cutout switch was in run; I had a conference call with Dispatch and Maintenance Control. It was determined that we could no longer proceed ETOPS and we would return to ZZZ. Now we were presented the question....... Hold to burn off several hours of fuel or to land overweight. With weather conditions considered; and the light continuing to illuminate; It was decided that the safest course of action was to get the airplane on the ground. I [requested priority handling] and had ARFF (Airport Rescue and Firefighting) equipment standing by. Landing was uneventful; and subsequent inspection by the firemen confirmed all appeared normal. Brake temps remained normal to gate. FO performed outstandingly! Gave thoughtful; professional and timely inputs throughout.
On Date; I was operating Aircraft X; with Captain Name; which was originally scheduled to fly from ZZZ to ZZZ1. Shortly after departure we were told to expect moderate to severe turbulence. We experienced moderate turbulence which caused our L ENG FUEL VAL light to illuminate. We ran the appropriate checklist and contacted Maintenance Control who told us to return to ZZZ. At this time we prepared the aircraft for landing; after running the appropriate checklist we determined that we were 30;000 pounds over weight for landing; but fell within the performance landing limits of the aircraft. Not knowing what the underlying issue was of the ENG FUEL VAL we decided to [request priority handling] in case of a flame out of our left engine. Due to [requesting priority] we ran the overweight landing checklist. We proceeded to the airport and made a safe landing; landing 22;000 pounds overweight.
