## Analysis

WHEN THE PLT CHECKED THE AIRSPEED INDICATOR ON TAKEOFF, HE SAW NO INDICATION OF SPEED & ABORTED THE TAKEOFF, BUT WAS UNABLE TO STOP ON THE REMAINING RWY. THE ACFT CONTD OFF THE DEPARTURE END, WHEN DOWN AN EMBANKMENT & BECAME INVERTED. AN EXAM REVEALED THE LACK OF AIRSPEED INDICATION WAS DUE TO A BLOCKAGE IN THE PITOT TUBE. THE BLOCKAGE HAD THE APPEARANCE OF A SUBSTANCE DEPOSITED BY MUD WASPS.
