ETOPS DESIGN APPROVAL TEST FLT ON A B777 WAS LEGALLY DISPATCHED WITH 1 IGNITOR INOP ON THE R ENG. AFTER LNDG AND SHUTDOWN; THE FLC PREPARED FOR THE RETURN LEG. IT WAS DISCOVERED THAT AN IGNITOR WAS THEN INOP ON THE L ENG; WHICH WOULD RENDER IT ILLEGAL FOR AN ETOPS FLT. HOWEVER; BECAUSE THE ETOPS PART WAS COMPLETED; RPTR CAPT APPLIED FAR 213 PART 25 FOR RETURN LEG.

Narrative

I WAS THE PLT ON A B777; FLYING ETOPS CYCLES FOR ETOPS TYPE DESIGN APPROVAL ON MAY/MON/96. THE ENGS WERE ROLLS ROYCE TRENT. MR A; FAA ACFT EVALUATION GROUP; WAS THE COPLT. OUR FIRST SORTIE WAS FLOWN FROM BFI TO PAE AND SIMULATED PART 121 OP PER THE ETOPS APPROVAL RULES. WE DISPATCHED WITH AN INOP IGNITOR ON THE R ENG. THE IGNITOR CIRCUIT BREAKER WAS PULLED AND COLLARED PER THE B777 DISPATCH DEV GUIDE (DDG) AND THE SORTIE WAS FLOWN UNEVENTFULLY. A COMPLETE POST FLT ENG SHUTDOWN FOLLOWED THE LNDG AT PAE. PREFLT AND ENG START WAS MADE AFTER 5 MINS OF ENG SHUTDOWN. FOLLOWING START OF THE L ENG; AN IGNITOR ON THAT SIDE FAILED. BECAUSE THE ACFT NOW HAD AN INOP IGNITOR ON EACH ENG; IT WAS NON DISPATCHABLE PER THE B777 ETOPS DISPATCH DEV GUIDE. AFTER CONFERRING WITH THE FLT TEST DIRECTOR AND MR A; I FERRIED THE ACFT BACK TO BFI UNDER PART 91 FOR DIAGNOSIS AND MAINT. THE ACFT WAS OPERATED UNDER SPECIAL AIRWORTHINESS CERTIFICATE -- EXPERIMENTAL; CATEGORY OF RESEARCH AND DEVELOPMENT; SHOW COMPLIANCE; AND MARKET SURVEY PER PART 91. THE B777 HAS BEEN CERTIFIED UNDER FAR 213; PART 25; FOR OP WITH ONLY 1 IGNITOR PER ENG REQUIRED. AS SUCH; I DEEMED THE ACFT SAFE TO OPERATE FOR THE FERRY FLT; AND CONSIDERED THE PART 121 ETOPS DISPATCH DEV GUIDE NO LONGER APPLICABLE AS WE WERE NOT CONDUCTING AN ETOPS CYCLE. I AM FILING THIS ASRS BECAUSE THERE MAY BE SOME QUESTIONING OF MY LEGALITY TO FERRY BY FAA MIDO (MAINT BRANCH). THEY MAY FEEL I WAS NON DISPATCHABLE PER THE B777 PART 121 ETOPS DISPATCH DEV GUIDE. TRUE; BUT I CONSIDERED ETOPS APPROVAL CYCLING TERMINATED FOR THIS FERRY FLT.
