Airport S36
N25320 has since been reassigned. It is now registered to a different aircraft (GARNHAM IAN R CHALLENGER II, built 1988), which was not involved in this event.

Factual narrative
THE INSTRUCTOR AND STUDENT ENCOUNTERED EXTREME TURBULENCE DURING A CLIMB TO 2000 FEET SO THE TOOK THE CONTROLS AND THE RETARDED POWER TO LOWER SPEED AND LOSE ALTITUDE. DESCENT WAS MADE FROM 1800 FEET TO 1300 FEET BEFORE THE THROTTLE WAS ADVANCED AND WHEN IT WAS THERE WAS NO ENGINE RESPONSE. A LANDING WAS ATTEMPTED ON A HIGHWAY WHEN THE ENGINE FAILED TO RESTART. DURING THE LANDING THE RIGHT WING STRUCK A SIGN WHILE THE PILOT MANEUVERED TO AVOID TRAFFIC. DIRECTIONAL CONTROL WAS LOST AND THE AIRCRAFT WENT THROUGH A SERIES OF YAWING, SLIDING MANEUVERS UNTIL IT STOPPED ON THE SHOULDER OFHIGHWAY 18. AN EXAMINATION OF THE ENGINE DISCLOSED NO PREIMPACT MALFUNCTION OR FAILURE. THE ENGINE WAS SUBSEQUENTLY STARTED AND IT IDLED SATISFACTORILY.
