Narrative:

I was assigned a block of space by lansing approach 5000-6000 ft and 10 DME from jxn VOR. At the end of the practice, I advised the student to descend to 5000 ft on a heading of 090 degrees and contact lansing approach to request an ILS runway 24 at jackson airport. Due to strong westerly winds and being busy helping the student set up for the approach, the aircraft drifted to 12 DME from jxn. The controller issued an immediate right turn and advised that we were about to exit his airspace. I took over the control of the airplane and reversed course toward jxn. The controller started vectoring us for the approach, and indicated that I was assigned a heading of 330 degrees. I did not hear the controller give me specific heading. My understanding was that I should immediately return to my assigned block of space until I am being vectored for the approach.

Original NASA ASRS Text

Title: BE55 INSTRUCTOR AND TRAINEE FLEW OUT OF ASSIGNED AIRSPACE.

Narrative: I WAS ASSIGNED A BLOCK OF SPACE BY LANSING APCH 5000-6000 FT AND 10 DME FROM JXN VOR. AT THE END OF THE PRACTICE, I ADVISED THE STUDENT TO DSND TO 5000 FT ON A HDG OF 090 DEGS AND CONTACT LANSING APCH TO REQUEST AN ILS RWY 24 AT JACKSON ARPT. DUE TO STRONG WESTERLY WINDS AND BEING BUSY HELPING THE STUDENT SET UP FOR THE APCH, THE ACFT DRIFTED TO 12 DME FROM JXN. THE CTLR ISSUED AN IMMEDIATE R TURN AND ADVISED THAT WE WERE ABOUT TO EXIT HIS AIRSPACE. I TOOK OVER THE CTL OF THE AIRPLANE AND REVERSED COURSE TOWARD JXN. THE CTLR STARTED VECTORING US FOR THE APCH, AND INDICATED THAT I WAS ASSIGNED A HDG OF 330 DEGS. I DID NOT HEAR THE CTLR GIVE ME SPECIFIC HDG. MY UNDERSTANDING WAS THAT I SHOULD IMMEDIATELY RETURN TO MY ASSIGNED BLOCK OF SPACE UNTIL I AM BEING VECTORED FOR THE APCH.
