Narrative:

We were returning to northeast pne VFR at night, when we were 20 or so mi from our destination, we began our descent from 4500' as we tuned in the ILS-24 at pne and made a small turn to intercept the localizer. We were receiving traffic advisories from TRACON and as we descended through 2700' MSL (approximately 2600' AGL) the controller asked if we were cleared into trenton's air traffic area. We responded negative and then looked around and realized where we were. We had been so engrossed in setting up for the approach that we were oblivious to trenton's proximity. At the time of the infraction, the plane was being flown by a friend in the right seat (he is a CFI). We fly together often and share plting 50/50. Whoever is not flying handles all radio and navigation work. Since I was navigating, I feel I am at least 50% responsible for allowing this to happen. But legally, the PIC is probably responsible. The question is, who was the PIC at the time? My friend and I do not have a standing rule on this. We probably should in the future.

Title: SMA PLT MAKING PRACTICE ILS APCH DESCENDS INTO ATA OF ARPT ALONG APCH ROUTE.

Narrative: WE WERE RETURNING TO NE PNE VFR AT NIGHT, WHEN WE WERE 20 OR SO MI FROM OUR DEST, WE BEGAN OUR DSNT FROM 4500' AS WE TUNED IN THE ILS-24 AT PNE AND MADE A SMALL TURN TO INTERCEPT THE LOC. WE WERE RECEIVING TFC ADVISORIES FROM TRACON AND AS WE DSNDED THROUGH 2700' MSL (APPROX 2600' AGL) THE CTLR ASKED IF WE WERE CLRED INTO TRENTON'S ATA. WE RESPONDED NEGATIVE AND THEN LOOKED AROUND AND REALIZED WHERE WE WERE. WE HAD BEEN SO ENGROSSED IN SETTING UP FOR THE APCH THAT WE WERE OBLIVIOUS TO TRENTON'S PROX. AT THE TIME OF THE INFRACTION, THE PLANE WAS BEING FLOWN BY A FRIEND IN THE R SEAT (HE IS A CFI). WE FLY TOGETHER OFTEN AND SHARE PLTING 50/50. WHOEVER IS NOT FLYING HANDLES ALL RADIO AND NAV WORK. SINCE I WAS NAVIGATING, I FEEL I AM AT LEAST 50% RESPONSIBLE FOR ALLOWING THIS TO HAPPEN. BUT LEGALLY, THE PIC IS PROBABLY RESPONSIBLE. THE QUESTION IS, WHO WAS THE PIC AT THE TIME? MY FRIEND AND I DO NOT HAVE A STANDING RULE ON THIS. WE PROBABLY SHOULD IN THE FUTURE.
