Looking at the NTSB report, Photo 6 does look like the Right canopy hinge,
not the Left canopy hinge as labeled. Also appears the hinge ripped away
from the forward deck, not the fuselage; sequence is unknown regarding
canopy latch failure or hinge foundation failure.

Rudi,
The long front hinges are still in tact so I'm guessing they had nothing
to do with the failure other than possibly contributing to any flex in
the canopy causing the latches to fail. If the rear latches continue to
hold with any airframe / canopy flex the canopy will not open. Simple
physics. If you don't trust your canopy latches then you need to
install a secondary stop much like the safety chain on a locked
residential door. Unlike "which radio should I get," a poor decision on
canopy latches could prove fatal.
