Narrative:

Copilot (first officer) was talking to passenger. Captain called for taxi clearance and clearance (VFR to lga) was told to taxi to runway 7. First officer finished with passenger and taxi began. After start checklist called for. While completing after start checklist and prestart checklist, captain taxied onto runway (approximately 500 yds from starting point). First officer called for ATC clearance with tower, when we were told that we were not cleared on the runway. Brought aircraft to a stop, asked tower if they wanted us to do a 180 degree and clear the runway. They said no, cleared for takeoff. I apologized and then made the takeoff. If first officer had been on the radio for taxi clearance (as usual) instead of captain calling for taxi clearance, he probably would have caught the fact that we were not cleared onto the runway. But he was off the radio at the time. Callback conversation with reporter revealed the following information. Since no flight attendant on this flight first officer was doing passenger safety announcement. Did not hear clearance so not aware should have held short. This was first officer second day with company, first day departing leb. Captain giving IOE! Very sharp first officer but not familiar with leb.

Title: COMMUTER TAXIES ONTO RWY WITHOUT CLRNC.

Narrative: COPLT (FO) WAS TALKING TO PAX. CAPT CALLED FOR TAXI CLRNC AND CLRNC (VFR TO LGA) WAS TOLD TO TAXI TO RWY 7. FO FINISHED WITH PAX AND TAXI BEGAN. AFTER START CHKLIST CALLED FOR. WHILE COMPLETING AFTER START CHKLIST AND PRESTART CHKLIST, CAPT TAXIED ONTO RWY (APPROX 500 YDS FROM STARTING POINT). FO CALLED FOR ATC CLRNC WITH TWR, WHEN WE WERE TOLD THAT WE WERE NOT CLRED ON THE RWY. BROUGHT ACFT TO A STOP, ASKED TWR IF THEY WANTED US TO DO A 180 DEG AND CLR THE RWY. THEY SAID NO, CLRED FOR TKOF. I APOLOGIZED AND THEN MADE THE TKOF. IF FO HAD BEEN ON THE RADIO FOR TAXI CLRNC (AS USUAL) INSTEAD OF CAPT CALLING FOR TAXI CLRNC, HE PROBABLY WOULD HAVE CAUGHT THE FACT THAT WE WERE NOT CLRED ONTO THE RWY. BUT HE WAS OFF THE RADIO AT THE TIME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. SINCE NO FLT ATTENDANT ON THIS FLT FO WAS DOING PAX SAFETY ANNOUNCEMENT. DID NOT HEAR CLRNC SO NOT AWARE SHOULD HAVE HELD SHORT. THIS WAS FO SECOND DAY WITH COMPANY, FIRST DAY DEPARTING LEB. CAPT GIVING IOE! VERY SHARP FO BUT NOT FAMILIAR WITH LEB.
