Narrative:

We were inbound to gainesville, fl, from the north. We had been flying nearly 2 hours, and were deviating for WX in the area. We were west of course, with the last clearance being to navigation direct gainesville airport when able. I turned the aircraft through some moderate to heavy rain showers (visually and with the WX radar) towards gnv. As I turned back to the left, which was more or less direct the field, another cell was in our way and very close to the aircraft. Without further clearance from ATC to deviation left, I turned the aircraft left of course to avoid the cell. I then told ATC we were left of course now, and would turn back direct gnv when able. ATC said we had just flown into the next sector's airspace (without them coordinating) and that we had not been cleared for a left deviation. I told them as we turned direct gnv, another cell was in our way, we had to deviation a couple mi to miss it, and could take the direct turn again shortly. We landed uneventfully 15 mins later. Factors to this problem were: WX (#1), ATC, (and running late), along with keeping the aircraft out of the numerous cells to give the passenger a decent ride.

Title: DHC8 CAPT DEVIATES AROUND TSTM CELLS WITHOUT CLRNC RESULTING IN ENTERING ANOTHER ARTCC SECTOR'S AIRSPACE.

Narrative: WE WERE INBOUND TO GAINESVILLE, FL, FROM THE N. WE HAD BEEN FLYING NEARLY 2 HRS, AND WERE DEVIATING FOR WX IN THE AREA. WE WERE W OF COURSE, WITH THE LAST CLRNC BEING TO NAV DIRECT GAINESVILLE ARPT WHEN ABLE. I TURNED THE ACFT THROUGH SOME MODERATE TO HVY RAIN SHOWERS (VISUALLY AND WITH THE WX RADAR) TOWARDS GNV. AS I TURNED BACK TO THE L, WHICH WAS MORE OR LESS DIRECT THE FIELD, ANOTHER CELL WAS IN OUR WAY AND VERY CLOSE TO THE ACFT. WITHOUT FURTHER CLRNC FROM ATC TO DEV L, I TURNED THE ACFT L OF COURSE TO AVOID THE CELL. I THEN TOLD ATC WE WERE L OF COURSE NOW, AND WOULD TURN BACK DIRECT GNV WHEN ABLE. ATC SAID WE HAD JUST FLOWN INTO THE NEXT SECTOR'S AIRSPACE (WITHOUT THEM COORDINATING) AND THAT WE HAD NOT BEEN CLRED FOR A L DEV. I TOLD THEM AS WE TURNED DIRECT GNV, ANOTHER CELL WAS IN OUR WAY, WE HAD TO DEV A COUPLE MI TO MISS IT, AND COULD TAKE THE DIRECT TURN AGAIN SHORTLY. WE LANDED UNEVENTFULLY 15 MINS LATER. FACTORS TO THIS PROB WERE: WX (#1), ATC, (AND RUNNING LATE), ALONG WITH KEEPING THE ACFT OUT OF THE NUMEROUS CELLS TO GIVE THE PAX A DECENT RIDE.
