Narrative:
During the descent from 6500 ft towards pea on an almost direct line from dpa about 10.5 mi out, the engine of the skyhawk experienced a catastrophic failure. We had to initiate a forced off airport landing which was successfully executed. Due to the fact that no damage or injury to the 2 occupants, the airplane or any other property occurred I decided to judge this event as an incident and not as an accident. Callback conversation with reporter revealed the following information: the reporter stated the engine failure was caused by a valve dropping into a cylinder causing catastrophic damage. The reporter said the off field landing was smooth and the airplane only rolled 285 ft after touchdown.
Original NASA ASRS Text
Title: A CESSNA 172 ON DSCNT AT 2500 FT DECLARED AN EMER AND MADE AN OFF ARPT LNDG DUE TO LOSS OF ENG PWR.
Narrative: DURING THE DSCNT FROM 6500 FT TOWARDS PEA ON AN ALMOST DIRECT LINE FROM DPA ABOUT 10.5 MI OUT, THE ENG OF THE SKYHAWK EXPERIENCED A CATASTROPHIC FAILURE. WE HAD TO INITIATE A FORCED OFF ARPT LNDG WHICH WAS SUCCESSFULLY EXECUTED. DUE TO THE FACT THAT NO DAMAGE OR INJURY TO THE 2 OCCUPANTS, THE AIRPLANE OR ANY OTHER PROPERTY OCCURRED I DECIDED TO JUDGE THIS EVENT AS AN INCIDENT AND NOT AS AN ACCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ENG FAILURE WAS CAUSED BY A VALVE DROPPING INTO A CYLINDER CAUSING CATASTROPHIC DAMAGE. THE RPTR SAID THE OFF FIELD LNDG WAS SMOOTH AND THE AIRPLANE ONLY ROLLED 285 FT AFTER TOUCHDOWN.
