Narrative:

I walked in to work and the police and civil air patrol informed me that my ELT was going off. By the time I had taken care of this, it was nearing departure time. I picked up the WX and checked the tail of the aircraft for any dents of lightning strikes. (My first officer had already preflted of course.) I went around the right wing and nose and headed for the cabin door when I noticed the hydraulic fill can access panel was open. I closed it and entered the aircraft. The WX was 300 ft with 2 mi and it was my first officer's leg. We were cleared for takeoff and I gave the aircraft to my first officer. He began to bring the power up and only got the propellers on the governors, then said nothing. I looked at him to see if he was ok. He appeared to be, so I asked him, 'are you ok?' he responded with, 'set maximum power.' I did this and looked at his airspeed. We were now at 100 KTS. I called V1, vr, V2, looked at my side of the aircraft, and had no airspeed indication. The pitot tube cover had been left on. I should have called an abort as soon as I noticed that my first officer was not responding normally. I should have also taken more time to observe the preflight activities of my first officer.

Title: INADEQUATE PREFLT.

Narrative: I WALKED IN TO WORK AND THE POLICE AND CIVIL AIR PATROL INFORMED ME THAT MY ELT WAS GOING OFF. BY THE TIME I HAD TAKEN CARE OF THIS, IT WAS NEARING DEP TIME. I PICKED UP THE WX AND CHKED THE TAIL OF THE ACFT FOR ANY DENTS OF LIGHTNING STRIKES. (MY FO HAD ALREADY PREFLTED OF COURSE.) I WENT AROUND THE R WING AND NOSE AND HEADED FOR THE CABIN DOOR WHEN I NOTICED THE HYD FILL CAN ACCESS PANEL WAS OPEN. I CLOSED IT AND ENTERED THE ACFT. THE WX WAS 300 FT WITH 2 MI AND IT WAS MY FO'S LEG. WE WERE CLRED FOR TKOF AND I GAVE THE ACFT TO MY FO. HE BEGAN TO BRING THE PWR UP AND ONLY GOT THE PROPS ON THE GOVERNORS, THEN SAID NOTHING. I LOOKED AT HIM TO SEE IF HE WAS OK. HE APPEARED TO BE, SO I ASKED HIM, 'ARE YOU OK?' HE RESPONDED WITH, 'SET MAX PWR.' I DID THIS AND LOOKED AT HIS AIRSPD. WE WERE NOW AT 100 KTS. I CALLED V1, VR, V2, LOOKED AT MY SIDE OF THE ACFT, AND HAD NO AIRSPD INDICATION. THE PITOT TUBE COVER HAD BEEN LEFT ON. I SHOULD HAVE CALLED AN ABORT AS SOON AS I NOTICED THAT MY FO WAS NOT RESPONDING NORMALLY. I SHOULD HAVE ALSO TAKEN MORE TIME TO OBSERVE THE PREFLT ACTIVITIES OF MY FO.
