Human Factors
A PA46 was on short final to Runway 14 when the Local Controller cleared a C172 for take off on the same runway. The separation decreased to less than minimum and the Controller first issued a go-around to the PA46. The Controller then cancelled the take off clearance for the C172; but it was too late as the aircraft was about to rotate. Now both aircraft were approximately 1;000 FT horizontally and the departure was climbing into the go-around aircraft that was issued runway heading. The Controller then issued an immediate right; and then changed to immediate left turn for the PA46 go-around. The Controller failed to calculate that the distance was too small and the air speed too fast on the PA46 to safely issue a take off clearance to the C172. Additionally; the Controller failed to use 'expedite' or 'immediate' in conjunction with the clearance. The Controller also failed to cancel the take off clearance in a timely manner.
I was working CIC when I observed Local Control clear a VFR PA46 on a  3 mile final Runway 14 to land; and then cleared a C172; IFR; for take off Runway 14. The C172 was slow to roll for takeoff; by this point the PA46 was 1 mile final so I told the Local Controller that it was not going to work; Local Controller sent the PA46 around runway heading; and then canceled the C172 takeoff clearance. By this point the C172 was too far along to stop their departure; Local Controller then told the PA46 to turn left immediately to avoid any further conflict. Better lack of situational awareness by the Controller. I noticed the Controller does not look out the window as often as they should working in a Tower environment. I have spoken to the individual before about this issue.
Tower Controller described a go around event resulting in a conflict between the go around aircraft and an aircraft cleared for take off; the reporter indicating the Local Controller has frequent separation issues.
