A partial power loss due to a Jabiru 2200 engine failure forced me to land my Alpi Aviation Pioneer 200 (CS-UPK) at low tide on an empty beach in Portugal ...
Wonderful landing, without a scratch ...
No. 3 cylinder exhaust valve adjuster jumped out of its seat during flight ...
More details, pictures, video and portuguese authorities (GPIAA) official report in my blog:
