Estes E motors dates

[KILTED COWBOY]

I keep hearing about checking the date codes on Estes E motors.
I have some E12-4 motors with the codes D 19 06 19
How can I look up to see if any reported issues.
Is there a chart?

This looks like the place to go:

https://www.rocketryforum.com/threads/suspected-bad-motor-list.150501/

It looks like D 19 06 19 is on the list.

Flew 105 rockets at the last launch.

5 were E12 and 1 was E9. All worked perfectly.

Date codes or perfect motors:

E9-4 061702 (they did not write down the letter - if there was one)

E12-4 A071417, H191219,unknown (they did not write it down...)
E12-6 B180718, H190919

I know this is an old thread. Maybe someone can help me teans late my E12-4 date code. H 19 02 20. I'm looking to see if these are after the issues Estes had with the E12s before.

Have you look at the 'MESS reports' for E12 to see problem date codes?

The Mess reports are here. As I recall you need to search around on this website.

Other way is to go to thrustcurve.com and look at E12 by Estes.
This shows:

There are 255 reported failures of this motor in the MESS database.
