Flight crew of an md super 80 continued to deviation around thunderstorms even though radar contact was lost with approach control and the aircraft penetrated foreign airspace contrary to ATC instructions of making a 180 degree turn. In addition, a restr area lies between the foreign border and the destination airport over which route the reporter indicates he followed.

Narrative:
Arriving tus from the east we approached a line of level 4 thunderstorms that ran north and south for a considerable distance. I elected to deviation around the south edge of the line as that appeared to be the safest route. As we proceeded south approach control advised us that we would be entering mexican airspace and suggested a 180 degree turn. I decided not to make a turn as doing so would have caused us to penetrate a storm cell. We proceeded south and were then informed by approach control that radar contact was lost. The controller suggested an altitude of 12000 ft and requested that we advise him when we were proceeding to tus. Shortly thereafter we began a turn to the west and then north direct tus maintaining 12000 ft and VMC at all times. An uneventful approach and landing was then accomplished.
Original NASA ASRS Text
Title: FLC OF AN MD SUPER 80 CONTINUED TO DEV AROUND TSTMS EVEN THOUGH RADAR CONTACT WAS LOST WITH APCH CTL AND THE ACFT PENETRATED FOREIGN AIRSPACE CONTRARY TO ATC INSTRUCTIONS OF MAKING A 180 DEG TURN. IN ADDITION, A RESTR AREA LIES BTWN THE FOREIGN BORDER AND THE DEST ARPT OVER WHICH RTE THE RPTR INDICATES HE FOLLOWED.
Narrative: ARRIVING TUS FROM THE E WE APCHED A LINE OF LEVEL 4 TSTMS THAT RAN N AND S FOR A CONSIDERABLE DISTANCE. I ELECTED TO DEV AROUND THE S EDGE OF THE LINE AS THAT APPEARED TO BE THE SAFEST RTE. AS WE PROCEEDED S APCH CTL ADVISED US THAT WE WOULD BE ENTERING MEXICAN AIRSPACE AND SUGGESTED A 180 DEG TURN. I DECIDED NOT TO MAKE A TURN AS DOING SO WOULD HAVE CAUSED US TO PENETRATE A STORM CELL. WE PROCEEDED S AND WERE THEN INFORMED BY APCH CTL THAT RADAR CONTACT WAS LOST. THE CTLR SUGGESTED AN ALT OF 12000 FT AND REQUESTED THAT WE ADVISE HIM WHEN WE WERE PROCEEDING TO TUS. SHORTLY THEREAFTER WE BEGAN A TURN TO THE W AND THEN N DIRECT TUS MAINTAINING 12000 FT AND VMC AT ALL TIMES. AN UNEVENTFUL APCH AND LNDG WAS THEN ACCOMPLISHED.
