I asked one guy if he had an axe or similar on board & he thought it was totally unnecessary.
He is foolish. LSA canopies can easily become jammed shut if the rails become warped in a minor impact and I have had personal experience of the over-centre levers jamming due to faulty maintenance on both the pilot and passenger side.
Add to that, most LSA do not have inertia reel harnesses. The standard LSA four point fixed harness allows no room to manoeuvre in restricted cockpit space in an emergency. When flying an LSA I carried a specially designed canopy breaker tool used for breaking out of Sabre and Macchi canopies if they jammed in a forced landing. Last year I gave away flying LSA's mainly because of my fear of being trapped if the canopy could not be released in event of a forced landing.
