## Analysis

THE PLT STATED THAT DURING THE TAKEOFF ROLL THE AIRSPEED HAD ACCELERATED THROUGH 128 KTS, BUT AS THE TAKEOFF CONTINUED THE AIRSPEED DROPPED TO 115 KTS & REMAINED BETWEEN 100-115 KTS. AFTER ROTATION THE ACFT WOULD NOT CLIMB OR ACCELERATE ABOVE 100-115 KTS. THE PLT RECHECKED THE POWER PLANT CONTROLS & ACFT SYSTEMS OPERATIONS. THE ACFT WOULD ONLY CLIMB TO ABOUT 20 FT AGL. THE PLT ELECTED TO ABORT THE TAKEOFF WITH ABOUT 1200 FT OF RUNWAY REMAINING. THE ACFT TOUCHED DOWN & THE PLT APPLIED MAXIMUM BRAKING, BUT THE ACFT RAN OFF THE END OF THE RWY COLLAPSING THE LANDING GEAR. THE PLT REPORTED APPLYING RIGHT RUDDER TO MAINTAIN DIRECTIONAL CONTROL DURING THE ATTEMPTED CLIMBOUT, BUT NO MALFUNCTION OF THE LEFT ENG WAS FOUND. ACCORDING TO THE OWNER'S MANUAL THE ACCELERATE STOP DISTANCE WAS AMPLE.
