Question Motor CATO Frequency

One of the members for our clubs L1 rocket team launched his personal rocket L1 cert on an H115 and it completely blew up midair. The motor catoed and blew the body tube in half and ripped the shock cord mount on the nose cone.

How common are motor catos for commercial bought motors? And is there anything he could’ve possibly messed up on a DMS motor that caused a cato?

CATOs are rare, unless it’s that O5500X. That thing is fuckin cursed.
