ON JUNE 18TH, 2022 WHILE FLYING ON A SHORT CROSS COUNTRY FROM KSRE TO 1K1 IN A 1965 MOONEY M20E WITH ONE PASSENGER. THE PILOT HEARD AND FELT A POWER LOSS WHILE AT CRUISE, NORTH BOUND AT 4500? MSL A FEW MILES DUE EAST OF GLENCO, OKLAHOMA. THE PILOT FOUND THAT THE POWER SETTING WAS AT IDLE POWER AND HAD NO CONTROL OF THE THROTTLE LEVER. MANIFOLD PRESSURE INDICATED 11 TO 12 INCHES AND RPM INDICATED 2000 RPM. NO MATTER HOW MANY TIMES THE PILOT PUSHED OR PULLED THE THROTTLE LEVER THERE WAS NO CHANGE IN THE IDLE POWER. THE PILOT TURNED THE AIRCRAFT DUE WEST IN THE DIRECTION OF STILLWATER, OKLAHOMA WHICH ALSO PARALLELED A LARGE INTERSTATE HIGHWAY TO THE LEFT. THE PILOT THEN BEGAN TROUBLESHOOTING PROCEDURES OF MIXTURE RICH, BUT THAT MADE THE ENGINE START RUNNING ROUGH SO HE SET IT BACK TO THE LEAN SETTING HE HAD FOR 4500? MSL. THE ENGINE RETURN TO RUNNING SMOOTH. THE PILOT THEN TURN ON THE ELECTRIC BOOST WITH FUEL SELECTOR ALREADY ON THE RIGHT FUEL TANK AND TRIED THE THROTTLE LEVER FULL FORWARD AND AFT SEVERAL TIMES. THERE WAS NO CHANGE IN POWER. THE PILOT THEN SWITCHED THE FUEL SELECTOR TO THE LEFT TANK AND AGAIN TRIED MOVING THE THROTTLE LEVER FORWARD AND AFT, BUT AGAIN NO CHANGE IN POWER SETTING. THE PILOT THEN SWITCHED BACK TO THE RIGHT FUEL TANK TRIED THE THROTTLE LEVER STILL WITH NO CHANGE IN POWER SETTING. THE PILOT CONTINUED MOVING THE THROTTLE MOST OF THE WAY DOWN JUST IN CASE A CONNECTION WAS MADE SOME HOW. AT THIS TIME, THE PILOT WAS ALREADY IN CONTACT WITH KANSAS CITY CENTER, AFTER TROUBLESHOOTING, THE PILOT TOLD THEM HIS SITUATION. THE CONTROLLER MENTIONED THE HIGHWAY TO MY LEFT AND CONFIRMED HE HAD THE HIGHWAY IN SIGHT. HE POSITIONED THE AIRCRAFT OVER THE HIGHWAY LOOKING FOR POTENTIAL OBSTACLES WHILE STILL MAINTAINING BEST GLIDE SPEED OF 105 MPH. THE IDLE POWER SETTING HE WAS LEFT IN DIDN?T ALLOW HIM TO MAINTAIN LEVEL FLIGHT. THE PILOT CONTINUED DESCENDING OVER THE HIGHWAY AND IT LOOKED CLEAR UNTIL ABOUT 50 TO 100 FEET OVER THE HIGHWAY. AT THAT HEIGHT A WHITE SUV APPEARED IN FRONT OF THE AIRCRAFT, SO THE PILOT DID A SLIGHT TURN TO THE LEFT THINKING HE DIDN?T WANT THE PROP TO MAKE CONTACT WITH THE VEHICLE. THE AIRCRAFT TOUCHED DOWN ON THE HIGHWAY WITH THE GEAR UP VERY SOFTLY AND STARTED A SKID STRAIGHT AHEAD. THEN SHORTLY AFTERWARD THE LEFT WING STRUCK A HIGHWAY SIGN AND THE AIRCRAFT DID A SLOW LEFT 360 DEGREES TURN UNTIL WE WERE HEADING THE ORIGINAL DIRECTION OF TOUCHDOWN AND THEN CAME TO A STOP ON THE RIGHT MEDIAN IN FRONT OF A SIDE BARRIER. THE AIRCRAFT DID NOT MAKE CONTACT WITH THE VEHICLE. BOTH PERSONS EXITED THE AIRCRAFT WITH NO INJURIES. INSPECTION OF THE AIRCRAFT REVEALED THAT ALL ENGINE CONTROLS HAD CONTINUITY. BOTH FUEL TANKS HAD SUBSTANTIAL FUEL IN THEM. NO ABNORMAL VISUAL FINDINGS WERE NOTED AT THIS TIME. ## The NTSB's investigation of this event (1) From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB CEN22LA255](https://openairdocs.org/ntsb/CEN22LA255), Jun 18, 2022: Mooney M20E (N5895Q), Stillwater, OK, substantial damage. Probable cause: The inadequate maintenance and inspection of the engine induction air coupling, which impeded airflow to the engine and resulted in the subsequent partial loss of engine power. 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.
