This is turning into a spinning thread, and we should still acknowledge we do not know what caused this accident.
With regard to spin recovery of today's Chipmunks, what is the effect of the removal of the old STRX (?spelling) radio and consequent rearward movement of CofG, on spin recovery of current Chipmunk, especially with a passenger? It is now very easy to exceed rear CofG limit with a passenger (yes - we should check balance each time before flight).
Apparently there is a TNS addressing the rear CofG movement after removal of the original radio.
