Aircraft Accident/Incident Report
Medina, Ohio 44215
Friday, September 10, 2004 11:50 EDT
NTSB Narrative Summary Released at Completion of Accident
During the takeoff roll, as the pilot rotated at 60 knots, he felt the airplane was "slow to lift," and aborted the takeoff. He reduced the power to idle and applied the brakes; however, the airplane traveled off the end of the runway, impacted a fence, and nosed over in a ditch. Examination of the Lycoming engine revealed low compression in the number 3 cylinder, due to a fractured cylinder ring. The last 100-hour inspection was performed approximately 3 weeks prior to the accident, and the airplane had flown 1 hour since then. The entry for the inspection revealed a compression check of the number 3 cylinder resulted in a reading of 55/80 psi. According to 14 CFR Part 43 Appendix D, "Each person shall inspect components of the engine and nacelle as follows...Internal engine - for cylinder compression...If there is a weak cylinder compression, [inspect] for improper internal condition and improper internal tolerances." Lycoming Service Instruction No. 1191A, stated in part, "Pressure readings for all cylinders should be nearly equal...a difference of 10 to 15 psi indicates an investigation should be made...if the pressure reading for cylinders is below 60 psi...removal and overhaul of the cylinders should be considered."
NTSB Probable Cause Narrative
The partial loss of engine power due to inadequate maintenance and by failure to comply with service instruction for low engine compression.
