Narrative:
A Tecnam P2008 JC Mk.II experienced an engine power loss when performing touch and goes and force landed in a field near Begbroke, Oxfordshire, shortly after takeoff from Oxford Airport (OXF/EGTK).

Cause
Examination of the aircraft found the left carburettor throttle butterfly valve spring was missing. This led to an imbalance between the two carburettors and resulted in the power loss. The cable operated throttle system relies on the butterfly valve spring tension to open the throttle as power demands are made when the hand control is pushed forwards in the cockpit. To close the throttle, the hand control is pulled rearwards against spring pressure.
Without the spring there can be a tendency for the throttle cable to ‘buckle’ rather than move the butterfly valve lever which is what happened in this case.

An engine ground run was carried out with the spring missing, which replicated the power loss symptoms experienced during the incident. The pilot suspects the spring broke and detached during the flight.
