Emergency landing after engine problem, Fokker S.11.1, PH-ACG, near Teuge International Airport
Immediately after liftoff, it became apparent that the historic aircraft did gain less altitude. A witness on the ground stated the engine was running smoothly, but that the aircraft remained in ground effect and did not climb nor accelerate. After this, the pilots noticed that the engine no longer provided the ability to keep the aircraft at a minimum altitude and decided to make an emergency landing in a field. The aircraft came to a stop upside down and sustained substantial damage. The two pilots on board received minor injuries.
The technical examination carried out that the engine mounting was bent and the engine controls no longer functioned fully. Also the lock mechanism of the mixture handle no longer functioned due to wear. This may have caused the mixture control to partially move from “rich” to “lean”, causing the engine to receive too little fuel and a loss of power.
