PLT OF SMA TEST FLT UNCERTAIN IF HE DEPARTED AND REENTERED ANC ARSA AND ATA PROPERLY.

Narrative

I DEPARTED ANCHORAGE INTL RWY 32 VIA PT MACKENZIE SUBSTATION DEP ON A MAINT TEST FLT AND RETURNED TO RWY 32 VIA THE POST OFFICE ARR. PART 93 FOR ANCHORAGE REQUIRES XING THE N HALF OF THE KNIK ARM (COOK INLET) ABOVE 2000 FT OR BELOW 1200 FT. I WAS PERFORMING A RETURN TO SVC TEST FLT IN AN SMA WHICH HAD A NEW ENG INSTALLED ALONG WITH AIRFRAME REPAIR. MY INTENTION WAS TO DEPART/RETURN ABOVE THE 2000 FT LIMIT IN XING THE KNIK ARM. I BELIEVE I WAS IN COMPLIANCE WITH PART 93 BUT I AM SOMEWHAT UNCERTAIN IN RECALLING THESE 2 FLTS. THE ACFT BEING FLOWN WAS MISRIGGED (L WING HVY) WITH SOME OTHER MINOR MECHANICAL PROBLEMS I BECAME AWARE OF ON CLB OUT. THIS IN COMBINATION WITH SOME UNFAMILIARITY OF THE ANCHORAGE AREA LEFT ME SOMEWHAT DISTRACTED OF EXACT POS/ALTS DURING CLB OUT AND DSCNT. THE ACFT WAS NEGATIVE TRANSPONDER. 2-WAY RADIO COM WAS MAINTAINED WITH ATC DURING BOTH FLTS. NO TFC CONFLICTS AROSE DURING THE FLTS. ATC DID NOT ADVISE OF ANY NON COMPLIANCE WITH PART 93. BETTER FAMILIARITY WITH THE AREA AND PROCS BEFORE PERFORMING TEST FLTS IN THE FUTURE WOULD PREVENT SUCH UNCERTAINTY.
