My Legacy open canopy story=

 

On a hot summer day in 2006 at Sierra Sky Park= airport in Fresno California I taxied to runway 30 (2473ft. X 50ft) with my= canopy open resting on my arm. When I taxied on to the runway I did no= t push up on the canopy to check that it is latched (I do now). When I rotat= ed at about 80kts I was startled by the sudden noise and wind of the ca= nopy coming open about 3 inches at the rear edge. I knew could not stop= on the remaining runway so I continued with a normal takeoff. I left the fl= aps at 10 deg. climbed at 120kts to 1,000 ft agl and trimmed the p= lane for level flight (I do not have an autopilot). I than put my hands on t= he trailing edge of the canopy frame and tried to move it(it had been i= n a stable open position so far). I could close it about 1 inch and open it a= bout 1inch further but that was as far as I could move it. At this poin= t I decided to return to land, I flew a normal pattern, as I flared for = ;landing the canopy opened another 2 inches. Throughout the flight the c= anopy never oscillated or affected the control of the aircraft.&nb= sp;

John, I left my gear down throughout my open canopy flight to make it l= ess likely to exceed 120Kts to minimize the slipstream forces on the canopy.=  I was afraid the canopy might be torn loose from the fuselage and also= by leaving the gear down it was one less thing to worry about.
