What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: the flight instructor and private pilot were preparing for a commercial pilot flight test scheduled that following day. While returning to Sanford airport, the instructor simulated an engine out exercise at 1,500' by retarding the throttle and applying carb heat. At 700' AGL, the instructor restored power; however, there was insufficient power available to sustain flight. The emergency landing area selected during practice was used and the aircraft landed safely without damage or injury. Investigation revealed the lower spark plugs were severely fouled by lead deposits. Engine operation after cleaning the plugs was satisfactory. The aircraft records indicated 70 hours of operation since February 15, 1993. The aircraft had been down for repairs and for sale for the previous years with numerous short ground runs on the engine. The aircraft was recently purchased and had flown 13 hours since the annual inspection was accomplished. Case closed.
