Narrative:
While climbing through FL50, north of Muret, significant engine vibration followed by a drop in engine speed. The pilot decided to land at Muret aerodrome on runway 30.
Landing too long, he attempted a go-around, which was ineffective due to engine problems. The aircraft landed off the runway and ran in a ditch just beyond the end of runway 30.
The exhaust flanges on cylinders 3 and 5 were detached from the axles, and the two tightening nuts were missing from the two flanges. The six wires from the ignition manifold, which ran close to the axles of cylinders 3 and 5 and up the rear of the engine on the right-hand side, showed significant signs of heating. A check of the shielding showed that it had deteriorated and that no spark could be produced.
