Event Description
A certified flight instructor reported that after the engine run-up, the aircraft departed from runway 23 to practice traffic pattern maneuvers. During the climb out, the airplane began to emit a "spitting" sound. The engine rpm dropped from 2500 to 1900, and the airspeed decreased to 60 knots. The certified flight instructor then took control of the flight and conducted a forced landing. The airplane touched down approximately 145 yards off the departure end of runway 23, at which point the nose wheel gear collapsed.
Post-Accident Examination
An examination of the aircraft after the accident revealed that the right wing assembly was buckled. The nose gear was broken off from the engine mounts, and the firewall was buckled. Further inspection of the engine controls showed that the mixture cable was broken.
Maintenance Records
A review of the maintenance logbooks indicated that there was no record of cable replacement within the 4859 flight hours.
