SMA X RWY INCURSION CROSSED OVER HOLD LINE FOR RWY; ACFT ON FINAL ISSUED GAR.

Narrative

SMA X LANDED ON RWY 26; CLRED RWY ONTO TXWY GOLF. X CONTACTED GND CTL FOR TAXI TO HANGAR. X WAS TOLD TO TAXI VIA DELTA TXWY HOLD SHORT OR RWY 31. X TAXIED VIA DELTA AFTER READBACK OF HOLD SHORT INSTRUCTION. X PROCEEDED PAST HOLD LINE FOR RWY 31. X ON FINAL RWY 31 WAS SENT AROUND. X WAS APPROX 50 FT PAST HOLD LINE BEFORE STOPPING. LCL CTL WAS UNSURE OF INTENTION. SO GAR WAS ISSUED. THIS ATM IS VERY FAMILIAR WITH LNS. WAS THIS A TEST ON HIS PART? I DON'T KNOW; MAYBE HE THINKS HE CAN DO WHATEVER HE WANTS AS A ATM AND BEING BASED HERE AT LNS. HE IS ALSO GOOD FRIENDS WITH OUR PRESENT ACTING ATM; AND VERY WELL AWARE OF THE PROB WITH RWY INCURSIONS AT LNS. SUPPLEMENTAL INFO FROM ACN 295547: I WAS WORKING THE TWR LCL CTL POS WHEN I OBSERVED GRUMMAN. X CROSS THE HOLD LINE AT RWY 31 TXWY DELTA; I HAD A CESSNA 150 SHORT FINAL RWY 31 CLRED FOR TOUCH AND GO. I POINTED X OUT TO GND CTL THE SAME TIME GRUMMAN X STOPPED. I CANCELED THE ARRS TOUCH AND GO CLRNC AND SENT HIM AROUND. THIS AMAZES ME CAUSE THIS GRUMMAN PLT HAS BEEN FLYING OUT OF THIS FIELD FOR 20 PLUS YRS AND IS AN AIR TFC MGR AT ANOTHER FACILITY. THE HOLD LINES WERE FRESHLY PAINTED LAST YR AND RED RWY SIGNS ARE AT EACH HOLD LINE. WHAT WE NEED ARE AUTOMOTIVE STOP SIGNS AT HOLD LINES WHERE GA ACFT FLY.
