1. Find out which of the two kits you need and replace the "suspect" parts.
2. Placard the panel to advise the occupants that no aerobatic maneuvers including spins are approved.
Considering that the 150 is 52 years old I'd say this is much ado about nothing but it is what it is.
I can testify to the 150 (I didn't know about the AD)... when I was getting my PPL, my CFI was showing me spins and recovery.. it was all loads of fun until during the recovery, full opposite rudder did nothing... he tried, I tried... still in the spin...it seemed like it didn't have much rudder travel, if any...this situation became a little disconcerting...... so we released rudder pressure and reapplied it and all of the sudden it came out of it like nothing ever happened about 5 turns after entry. We landed at the closest airport... looked everything over... tested it on the ground, everything seemed perfect - but we never spun that sucker again - We're not sure what happened, an A&P looked everything over and said nothing was wrong.
as a side note - I'm pretty sure any gyro linked to an AP will be heavily damaged if it tumbles... could be wrong about that though.
