## Discrepancy

AIRCRAFT WAS GROUNDED: FLIGHT CREW REPORTED THAT SHORTLY AFTER LEVEL OFF AT FL 320 THEY EXPERIENCED LIGHT WAKE TURBULENCE IMMEDIATELY FOLLOWED BY ECAM ENGINE 2 STALL AND ENGINE 2 N1 BEGAN ROLL BACK BUT RETURNED TO NORMAL WITHIN A FEW SECONDS. THE ECAM THEN SELF CLEARED. ALL ENGINE INDICATIONS WERE NORMAL AFTER THAT. MAINTENANCE FOUND BLEED VALVE SOLENOIDS 7A (AALA202511107110) AND 7C (AALA202511103184) FAILING THE BLEED VALVE CHECK AND REPLACED BOTH OF THEM. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
