THE FLC EXPERIENCED A STATIC DISCHARGE; LOSS OF ACFT CTL FOR ABOUT 10 SECONDS AND THE ACFT FELL 3000 FT IN SEVERE TURB WHILE DEVIATING AROUND A TSTM. ACCOMPANYING THE STATIC DISCHARGE THE L GENERATOR; THE AUTOPLT; AUTOTHROTTLE AND FMC DROPPED OFF THE LINE. THE CREW GOT THE LAST COMPONENTS BACK WHEN PWR WAS RESTORED TO THE L GENERATOR. THE FLC DECLARED AN EMER AND DIVERTED TO TPA. 1 PAX WAS BUMPED ON THE HEAD.

Narrative

AT APPROX XA35Z ACFT WAS AT FL350; .78M; SMOOTH AIR; HIGH CIRRUS. WE HAD JUST FINISHED DEVIATING 25-35 NM SW OF TLH AROUND A LINE OF TSTMS. WE WERE FOLLOWING A LINE OF ACFT WHO WERE ALSO DEVIATING ALONG OUR RTE. ATC HAD JUST CLRED US DIRECT PIE; ON COURSE. WHEN WE WERE APPROX 50 NM N OF PIE; RADAR ON SHOWING NO RETURNS; AND SEAT BELT SIGN ON; THE ACFT ENCOUNTERED 2 SMALL BUMPS THEN ENCOUNTERED SEVERE TURB. AT THE SAME TIME; THERE WAS A STATIC DISCHARGE. THE L GENERATOR DROPPED OFF LINE; ALONG WITH THE AUTOPLT; AUTOTHROTTLE AND FMC. THE ACFT WAS UNCTLABLE FOR APPROX 10 SECONDS. WE DSNDED APPROX 3000 FT BEFORE WE REGAINED CTL. THE GENERATOR; AUTOPLT; AUTOTHROTTLE BACK ON LINE. AN EMER WAS DECLARED AND WE DIVERTED INTO TPA. THE FLT ATTENDANTS RPTED THERE SEEMED TO BE NO APPARENT INJURIES; SO A SLOW DSCNT AND APCH WAS MADE TO CHK FLT CTLS. THE ACFT WAS ESTABLISHED ON LONG FINAL; CONFIGURING EARLY. NO FLT ABNORMALITIES WERE ENCOUNTERED. AN UNEVENTFUL LNDG WAS MADE. PARAMEDICS MET THE ACFT AT THE GATE. 1 FEMALE PAX COMPLAINED OF A BUMP ON THE HEAD. NO OTHER INJURIES RPTED. A SEVERE TURB INSPECTION WAS MADE. ACFT DEEMED AIRWORTHY BY MAINT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED HE WAS THE FO. HE WAS NOT THE PF. THE FMC WENT BLANK WITH THE LOSS OF THE #2 GENERATOR; BUT ALL COMPONENTS WERE RESTORED WHEN THE #2 GENERATOR WAS BACK ON LINE. THE REASON THE RPTRS CALLED THE LIGHTNING PHENOMENA A STATIC DISCHARGE INSTEAD OF A LIGHTNING STRIKE WAS THAT AFTER DISCUSSION AND CHKING THE ACFT OVER; THERE WAS NO ENTRY OR EXIT INDICATION. THERE WERE NO OTHER RPTS OF PROBS BY OTHER ACFT CIRCUMNAVING THE WX TO THE RPTR'S KNOWLEDGE. THE RPTR SAID THERE WAS NOTHING THE CREW WOULD DO DIFFERENTLY OTHER THAN STEER CLR AWAY FROM THE TSTM. THERE HAS BEEN NO FURTHER ACTION TAKEN SINCE HE SENT IN HIS RPT.
