Narrative:

I was holding short of runway 26 at cma when the tower controller said 'aircraft X, traffic is a cessna on a 1 1/2 mi final, cleared for takeoff.' 2 aircraft were on final approach and both appeared to be closer than 1 1/2 mi, but it looked like I had enough room to take off safely. I acknowledged the clearance and expedited my takeoff roll. As I lined up on the centerline and began the takeoff, the aircraft on short final announced that he was going around because of a cessna (me) on the runway. Tower acknowledged and told him to go around. The pilot on short final told the tower controller that 'someone should stop that guy.' (by then I was lifting off.) the tower controller, rather tersely, told the pilot to 'go around.' the second aircraft on final also initiated a go around. Though I feel that the go around probably wasn't necessary for either aircraft, I believe the tower controller misjudged the distance of the aircraft on final, or forgot about one of them. In hindsight, I should have refused the takeoff clearance and held short for the 2 landing aircraft.

Original NASA ASRS Text

Title: CESSNA 172 ACCEPTS 'POS AND HOLD' AND TKOF CLRNC WITH ACFT ON SHORT FINAL CAUSING 2 GARS AT CMA.

Narrative: I WAS HOLDING SHORT OF RWY 26 AT CMA WHEN THE TWR CTLR SAID 'ACFT X, TFC IS A CESSNA ON A 1 1/2 MI FINAL, CLRED FOR TKOF.' 2 ACFT WERE ON FINAL APCH AND BOTH APPEARED TO BE CLOSER THAN 1 1/2 MI, BUT IT LOOKED LIKE I HAD ENOUGH ROOM TO TAKE OFF SAFELY. I ACKNOWLEDGED THE CLRNC AND EXPEDITED MY TKOF ROLL. AS I LINED UP ON THE CTRLINE AND BEGAN THE TKOF, THE ACFT ON SHORT FINAL ANNOUNCED THAT HE WAS GOING AROUND BECAUSE OF A CESSNA (ME) ON THE RWY. TWR ACKNOWLEDGED AND TOLD HIM TO GO AROUND. THE PLT ON SHORT FINAL TOLD THE TWR CTLR THAT 'SOMEONE SHOULD STOP THAT GUY.' (BY THEN I WAS LIFTING OFF.) THE TWR CTLR, RATHER TERSELY, TOLD THE PLT TO 'GO AROUND.' THE SECOND ACFT ON FINAL ALSO INITIATED A GAR. THOUGH I FEEL THAT THE GAR PROBABLY WASN'T NECESSARY FOR EITHER ACFT, I BELIEVE THE TWR CTLR MISJUDGED THE DISTANCE OF THE ACFT ON FINAL, OR FORGOT ABOUT ONE OF THEM. IN HINDSIGHT, I SHOULD HAVE REFUSED THE TKOF CLRNC AND HELD SHORT FOR THE 2 LNDG ACFT.
