Looping a 2-33

Did you actually read the Service Bulletin? It says "Aerobatics are not approved or RECOMMENDED" - because "the structural design levels of the sailplane could be exceeded".

every 2-33 manual I have seen says mild aerobatcs to 80 mph can be done (1-5 in link below). To loop a 2-33 is not dangerous.

Mik cites 2-33 POH to underscore his claim that 'To loop a 2-33 is not dangerous. He overlooks that Service Bulletin 'SA-003 Aerobatics in Schweizer Sailplane 25 Mar 1987' supersedes the POH.

That is a black and white case of being 'uninformed'. It's irresponsible (aka dangerous) to propagate misinformation wrt the manufacturer's position on the suitability of an aircraft for aerobatics.

That's my only point. Anyone who chooses to do aerobatics in a 2-33 should be aware of the manufacturer's position and in particular they should be aware that the POH was superseded by a service bulletin.

WRT how I will choose to fly a 2-33, the accumulated abuse and neglect of most 2-33s outweighs the possibility that SA-003 was 'liability dodging BS' back in 1987 (28 years ago).
