Narrative:

Problem arose due to passenger headphones. I allowed myself to become distraction with trying to correct a noise problem with back seat passenger headphones. In the course of directing attention to the back seat, my left hand caused slight pressure on the yolk thereby causing the aircraft to climb into the outer shelf of the beale AFB class C airspace. I discovered the altitude deviation when I turned my attention forward again. I leveled the aircraft at 2000 ft while exiting the class C outer ring boundary. I should not have allowed myself to become distraction while operating under the class C. Fatigue due to the late hour may have been a factor.

Title: POSSIBLE INCURSION OF BEALE AFB CLASS C AIRSPACE BY PA28.

Narrative: PROB AROSE DUE TO PAX HEADPHONES. I ALLOWED MYSELF TO BECOME DISTR WITH TRYING TO CORRECT A NOISE PROB WITH BACK SEAT PAX HEADPHONES. IN THE COURSE OF DIRECTING ATTN TO THE BACK SEAT, MY L HAND CAUSED SLIGHT PRESSURE ON THE YOLK THEREBY CAUSING THE ACFT TO CLB INTO THE OUTER SHELF OF THE BEALE AFB CLASS C AIRSPACE. I DISCOVERED THE ALTDEV WHEN I TURNED MY ATTN FORWARD AGAIN. I LEVELED THE ACFT AT 2000 FT WHILE EXITING THE CLASS C OUTER RING BOUNDARY. I SHOULD NOT HAVE ALLOWED MYSELF TO BECOME DISTR WHILE OPERATING UNDER THE CLASS C. FATIGUE DUE TO THE LATE HR MAY HAVE BEEN A FACTOR.
