## Discrepancy

ENGINE 2 STALL ECAM MSG MOMENTARY AT SAME TIME OF LIGHTNING STRIKE.  CREW ADVISED OF AUDIO POP AT SAME TIME AS LIGHTNING STRIKE.  EVENT OCCURRED ACFT TURNING FINAL.  ENGINE PARAMETERS NORMAL BEFORE AND AFTER STALL EVENT.  COMPRESSOR STALL NEAR LIGHTENING STRIKES IS NOT UNCOMMON.  THIS IS DUE TO THE TUBULENCE CREATED BY THE LIGHTENING.  THIS ENGINE WAS INSPECTED PER THE AIRBUS TSM AND NO DISCREPANCIES WERE FOUND.  AS A PRECAUSTION, THE VSV SYSTEM WAS LUBRICATED.  THE ENGINE PASSED ITS POWER ASSURANCE RUN AND RETURNED TO SERVICE.
