A TEST PLT IS UNABLE TO GET AN ENG RESTARTED THAT WAS PURPOSELY SHUT DOWN FOR A FLT TEST. THE PLT ALSO TEMPORARILY LOST THE OTHER GENERATOR AND DSNDED OUT OF ASSIGNED BLOCK ALT AIRSPACE.

Narrative

THIS WAS A QUALITY ASSURANCE FLT. THE FLT WAS CONDUCTED ON AN IFR FLT PLAN. I HAD A BLOCK AIRSPACE ASSIGNMENT FROM FL270 TO FL250. FLT TESTS INCLUDED; BUT WERE NOT LIMITED TO; CONFIRMING A FAULT WITH THE #2 GENERATOR; ENG SHUTDOWNS AND RESTARTS. I WAS ON VECTORS WITHIN TEST AREA. THE FIRST ENG SHUTDOWN WAS THE L ENG WITH A WINDMILLING START. WHILE STILL AT FL250; I SHUT THE L ENG DOWN FOR THE SECOND TIME AFTER THE APPROPRIATE COAST DOWN/COOL DOWN PERIOD AND ATTEMPTED TO PERFORM THE STARTER ASSISTED START. (THE SHUTDOWN AND THE RESTARTS WERE ALL CONDUCTED USING THE PROCS SET FORTH IN PLT CHKLIST.) THE STARTER ASSISTED START OF THE L ENG FAILED. THE R ENG'S 'GENERATOR FAIL' ANNUNCIATOR ILLUMINATED AND NUMEROUS OTHER ANNUNCIATORS ILLUMINATED SUBSEQUENT TO THE FAILURE OF THE R GENERATOR. I WAS RELATIVELY CLOSE TO BEECH FIELD; SO I OPTED TO CLB BACK TO FL270 AND ATTEMPT AN AIR START IN THE HOPES OF REGAINING THE GENERATOR PWR. UNABLE TO GET THE ENG STARTED; I ADVISED ZKC THAT I WAS SINGLE ENG AND HAD A DUAL GENERATOR FAILURE. HE ASKED IF THIS WAS CONSIDERED AN EMER AND I THEN DECLARED AN EMER. UPON CONTACTING WICHITA APCH; I REQUESTED AND WAS GIVEN VECTORS FOR THE VOR/GPS B APCH. DURING THE VECTORS; ATC ADVISED ME THAT I HAD BEEN REQUESTED TO CONTACT MY OPS. IT WAS AT THIS POINT THAT I WAS OPERATING IN VFR CONDITIONS WITH VISIBILITY IN EXCESS OF 5 MI. I ADVISED ATC THAT I WAS VFR AND THAT I COULD CALL MY OPS. HE ASKED ME IF I WANTED TO CANCEL IFR. I CANCELED IFR AND CONTACTED OPS WHO ASKED ME TO TRY TO RESET THE GENERATOR BY HOLDING THE RESET BUTTON TO RESET FOR 5 SECONDS. (THIS PROB WAS RECOMMENDED BY A COMPANY PLT WHO HAD A GENERATOR FAILURE ON THIS ACFT YESTERDAY AND HAD BEEN SUCCESSFUL IN REINSTATING ITS FUNCTION BY HOLDING THE SWITCH TO RESET FOR 5 SECONDS.) I HAD PREVIOUSLY ATTEMPTED A MOMENTARY AND SLIGHTLY EXTENDED TIME FOR THE RESET AND SO I HELD THE RESET AND COUNTED 8 SECONDS. THE #2 GENERATOR DID RESET AND FUNCTION. ALL OF THE ACFT'S EQUIP WHICH REQUIRES ELECTRICAL PWR WAS AT THIS POINT AVAILABLE TO ME FOR THE LNDG. A SINGLE ENG LNDG WAS CONDUCTED WITHOUT INCIDENT. I WAS MET BY THE FIRE TRUCK AND THROUGH HAND SIGNALS; IT WAS COMMUNICATED THAT THE ACFT WAS SAFE TO TAXI TO PARK. TOTAL FLT TIME WAS 52 MINS AND I LANDED WITH APPROX 2000 LBS OF FUEL ON BOARD. AFTER PARKING; I DISCUSSED THE INDICATIONS AND PROCS I USED WITH COMPANY.
