First flight 2/8 1927 at Warnemünde. With a BMW VIa engine, not enough reliable and too low power.for the long
The a modified with a Packard engine lent from Severa GmbH. .During trials the floats were enlarged with a
second step and the forward struts became longer. The trials ended with a record flight ( 11 hours with a payload
of 1000 kg). Then came the record attempt in 1927
12.10 take off Warnemünde 12:21H, landed Brunsbüttel 14.20H
13.10 take off Brunsbüttel 09:34H and landed Wilhelmshaven 10:18H
14.10 take off Wilhelmshaven 10:58H and landed Amsterdam 13:02H
16.10 take off Amsterdam 08:05H and landed Vigo 16.00H
18.10 take off Vigo 06:05H and landed Lisbon 08:55H
04.11 take off Lisbon 04:25H and landed Horta, the Azores 14:10H
13.11 take off Horta 02:33H but forcelanded following its third take off attempt and due to the heavy swelling
overturned. Besides the two crew already mentioned there was also a Packard engine engineer onboard, Rohde.
All three were rescued unharmed but the aircraft was a complete write off. Nothing known about the wreck, but
most probably scrapped in some local scrapyard...
A relatively large long-range aircraft, the He 6 bore many features of the earlier Heinkel seaplane monoplanes, but accomodated its crew of three to four in an enclosed cockpit. Crew generally comprised a pilot, navigator and radio operator, and reconnaissance was again to be the task of this seaplane. One example, D-1220 (c/n.286)*, attempted to reach Newfoundland in Autumn 1927, via Lisbon and the Azores. It departed from Warnemunde on October 12 but on the 13th of the following month**, it capsized off the Azores and could proceed no further.
