Cartridges on fire extinguisher bottles SA-365-C2
Hello all!
I have a question, I hope someone can answer me.
On helicopter SA-365-C2 we have engine fire bottles PN: 860650.
On each bottle there are 2 installed cartridges PN: 861-305 and PN: 861-315.
These PN's are written on existing cartridges, as well as in IPC!
Life limit of these cartridges is 3 years.
The problem is, we can't find anywhere PN: 861-315. The supplier does not recognise this PN. It's OK for PN: 861-305, but not PN: 861-315!
Did anyone have this problem? Is there a replacement PN available?
Does any SB exist for this problem?
Thank you for all thoughts!
