Cross-reference check
Relationships and limits.
- Four rows associate 103278-13S2 with kit 4200097-3, Mod 25F586C, and SB21-160.
- Two rows use pre SB21-3621 language for the same S2 record.
- The IPC does not print a direct S1-to-S2 or S2-to-18 replacement instruction.
The S2 suffix does not erase the configuration notes. Keep the kit number, MOD status, service-bulletin status, aircraft serial, and installed item with the sourcing request.

Common questions about 103278-13S2.
What configuration note is printed for 103278-13S2?
Four rows reference kit 4200097-3, Mod 25F586C, and SB21-160. Two additional rows call the S2 record pre SB21-3621.
Is 103278-13S2 the same record as 103278-18?

No. The IPC divides it among six figure and item rows with distinct printed serial blocks. Use the row matching the installed configuration.
