Narrative:

Myself and another flight instructor were flying VFR when we mutually decided to request a VFR practice approach into oceanside municipal airport which is a non twred field. I was advised that another aircraft was shooting the approach, so I asked to hold at the oceanside VOR. The controller cleared me to hold at 3000 ft, but I requested 3500 ft to remain clear of clouds and this was approved. During the inbound turn, I was cleared for the VOR approach into oceanside and was instructed to switch to the CTAF at the VOR. During this time, I was flying the aircraft while the other instructor was setting the navigation and communication radios. At the VOR, I switched to CTAF and then maneuvered to dodge a cloud layer at 2300 ft when I noticed that the inbound course had swung from the left to the right side of the CDI. At this point my partner called the field was in sight. I then proceeded directly to the field, at which time I self announced the downwind and base legs, then noticed the military helicopters on the field. I had flown directly into camp pendleton's restr airspace. It was too late to do anything but reverse course and leave. I contacted socal once I exited the restr airspace. The factors which led to this event were a lack of situational awareness, a failure to fly the charted approach, a lack of determining who was PIC, and dodging clouds while tracking a course. This was such a rookie mistake. Neither of us can believe that we let this happen!

Title: 2 FLT INSTRUCTORS IN A C411 LINE UP WITH A MIL FIELD WHILE MAKING A PRACTICE APCH TO OCN.

Narrative: MYSELF AND ANOTHER FLT INSTRUCTOR WERE FLYING VFR WHEN WE MUTUALLY DECIDED TO REQUEST A VFR PRACTICE APCH INTO OCEANSIDE MUNICIPAL ARPT WHICH IS A NON TWRED FIELD. I WAS ADVISED THAT ANOTHER ACFT WAS SHOOTING THE APCH, SO I ASKED TO HOLD AT THE OCEANSIDE VOR. THE CTLR CLRED ME TO HOLD AT 3000 FT, BUT I REQUESTED 3500 FT TO REMAIN CLR OF CLOUDS AND THIS WAS APPROVED. DURING THE INBOUND TURN, I WAS CLRED FOR THE VOR APCH INTO OCEANSIDE AND WAS INSTRUCTED TO SWITCH TO THE CTAF AT THE VOR. DURING THIS TIME, I WAS FLYING THE ACFT WHILE THE OTHER INSTRUCTOR WAS SETTING THE NAV AND COM RADIOS. AT THE VOR, I SWITCHED TO CTAF AND THEN MANEUVERED TO DODGE A CLOUD LAYER AT 2300 FT WHEN I NOTICED THAT THE INBOUND COURSE HAD SWUNG FROM THE L TO THE R SIDE OF THE CDI. AT THIS POINT MY PARTNER CALLED THE FIELD WAS IN SIGHT. I THEN PROCEEDED DIRECTLY TO THE FIELD, AT WHICH TIME I SELF ANNOUNCED THE DOWNWIND AND BASE LEGS, THEN NOTICED THE MIL HELIS ON THE FIELD. I HAD FLOWN DIRECTLY INTO CAMP PENDLETON'S RESTR AIRSPACE. IT WAS TOO LATE TO DO ANYTHING BUT REVERSE COURSE AND LEAVE. I CONTACTED SOCAL ONCE I EXITED THE RESTR AIRSPACE. THE FACTORS WHICH LED TO THIS EVENT WERE A LACK OF SITUATIONAL AWARENESS, A FAILURE TO FLY THE CHARTED APCH, A LACK OF DETERMINING WHO WAS PIC, AND DODGING CLOUDS WHILE TRACKING A COURSE. THIS WAS SUCH A ROOKIE MISTAKE. NEITHER OF US CAN BELIEVE THAT WE LET THIS HAPPEN!
