## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) ON FEBRUARY 7, 2001, AT 1500 CST, A CESSNA 172 AIRPLANE, N980SP, OPERATED BY LOUISIANA TECH UNIVERSITY, SUSTAINED MINOR DAMAGE DURING A FORCED LANDING AFTER A LOSS OF POWER WHILE PRACTICING POWER STALLS NEAR RUSTON, LA. AS A RESULT OF THE INITIAL INVESTIGATION PROBABLE CAUSE OF THE INCIDENT HAS NOT BEEN DETERMINED.  CESSNA, LYCOMING AND THE NTSB ARE STILL INVESTIGATING THIS SUDDEN ENGINE STOPPAGE THAT HAS CAUSED SEVERA OWNER/OPERATORS ACCIDENTS DUE TO THE SAME SITUATION DEVELOPING.  LA. TECH WITH APPROVAL OF CESSNA AND LYC. HAVE ISSUED ADDITIONAL I0-360 SERIES IDLE SPEED AND MIXTURE ADJUSTMENT PROCEDURES FOR THEIR STUDENTS/AIRCRAFT. LATER FINDING DISCOVERED THAT THE IDLE AND MIXTURE SETTINGS WERE THE PROBLEM.  THE MIXTURE SETTING WAS TOO RICH CAUSING A 200 RPM RISE WHEN THE ENGINE WAS LEANED WITH THE MIXTURE CONTROL.  ALSO, THE ENGINE WOULD NOT IDLE AND QUIT WHEN THE THROTTLE WAS PULLED BACK.  INVESTIGATORS AGREED THAT SOMETHING WAS NOT RIGHT WITH THE FUEL METERING SYSTEM ON THE ENGINE. LYC. HAS ISSUED A IO-360 SERIES FUEL MIXTURE LEANING PROCEDURE SERVICE INSTRUCTION, NO.1094, TO RECOMMEND OPERATIONAL GUIDELINES DURING ENGINE OPERATION.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
