Emergency landing on water
During water landing tests with the landing gear retracted, it has been
observed that the fuselage can submerge completely. The following
procedure is recommended for an emergency landing on water:
1. Dump all ballast.
2. Make a radio call.
3. Extend the landing gear.
4. Undo the parachute harness during the downwind leg.
5. Ensure that the safety straps are tight.
6. Try to land parallel to the shore and against the wind.
7. Close the water dump valves before touchdown.
8. Touchdown with the landing gear extended and speed as low as
possible.
9. At the touchdown point use the left arm to protect the face
against possible canopy fracture.
10. After touchdown undo the belt harnesses.
If the aircraft has sustained no damage to the water tanks it may stay
afloat for a long period. Swimming may be the only option when the
airframe starts sinking.
