A Bird at the wrong time and place. Both aircraft and bird took off at the same time. However, the flight path of the Guinea Fowl led directly into the spinning propeller.
The pilot cut the engine and did an emergency landing.
The largest splinter was found 100m distant. The engine sustained nil damage, although some engine mounts needed replacement.
The pilot stated vibration levels were so severe that his eyesight was seriously affected.
(The Guinea Fowl was charged with contravening every air navigation rule in the book . . . charges were subsequently dropped due to lack of evidence . . . only feathers remained!)
