- Only a hard shock on a hard obstacle can break a spar.
- Never a spar can break when flying under the kite maximum wind limit.
- If a spar is seen brocken when flying, this spar has been broken during the last crash.
- If a spar is disfitted when flying, this spar has not been re-fitted correctly after the last crash.
- A brocken spar is not cut in two pieces but only flattened, because it is dislaminated.
