There is a new Service Bulletin on the Blanik L-23 that requires
Magnafluxing the "U" shape bracket that connects the two elevator halves.
The bracket on our ship had 3 cracks. If you have a Blanik L-23 and have
not had it checked would suggest you do so. Losing half an elevator you
might still have control. Losing both halves would probably be parachute
time.

For those that have had the check, are cracks being found?
