Narrative:
I was descending over class C airspace in light to moderate turbulence. I attempted to level off well above the class C 4400 ft ceiling, but full power in a climbing attitude was still producing a descent. My altimeter needle was bouncing around 4400 ft prior to being able to climb out of the descending air. I am concerned that I may have entered the class C airspace without communications during this event. I have had little experience in turbulent conditions such as those I encountered this day. To prevent a recurrence, I will allow for such altdevs in these conditions and communicate with ATC if near their airspace.

Title: C152 PVT PLT PERFORMS AN UNAUTH PENETRATION OF AIRSPACE WHEN LOSS OF ACFT CTL IS EXPERIENCED DUE TO INFLT ENCOUNTER WITH TURB.
Narrative: I WAS DSNDING OVER CLASS C AIRSPACE IN LIGHT TO MODERATE TURB. I ATTEMPTED TO LEVEL OFF WELL ABOVE THE CLASS C 4400 FT CEILING, BUT FULL PWR IN A CLBING ATTITUDE WAS STILL PRODUCING A DSCNT. MY ALTIMETER NEEDLE WAS BOUNCING AROUND 4400 FT PRIOR TO BEING ABLE TO CLB OUT OF THE DSNDING AIR. I AM CONCERNED THAT I MAY HAVE ENTERED THE CLASS C AIRSPACE WITHOUT COMS DURING THIS EVENT. I HAVE HAD LITTLE EXPERIENCE IN TURBULENT CONDITIONS SUCH AS THOSE I ENCOUNTERED THIS DAY. TO PREVENT A RECURRENCE, I WILL ALLOW FOR SUCH ALTDEVS IN THESE CONDITIONS AND COMMUNICATE WITH ATC IF NEAR THEIR AIRSPACE.
