2012 Piper PA 34 200T Seneca II Ferry from UK with Emegency Gear Down 

Ferry from Seething/UK to St. Gallen/Switzerland with fuel stop in Luxembourg. Lost hydraulic pressure during flight. At landing, we made a tower fly by, gear was not fully down, so we made a free drop and second fly by and gear seams to be fully down and locked. But still the landing is a surprise, but all went OK!
