HALLADAY ROY LOCKHEED
The pilot reported that, upon landing, he activated the canopy motor to open the canopy about 2 inches, but the canopy continued to open, separated from the airframe, and struck the empennage. He added that it was standard procedure upon landing to open the canopy slightly to aid in slowing the airplane and egress in a runway excursion event. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot added that the emergency canopy release, which anchors the canopy to the airframe when the canopy motor was turned on, was inadvertently released during the flight.
