Cross-reference check
Relationships and limits.
- TP42001 repeats in the ATA 29 emergency brake installation and the ATA 32 wheel-brake pressure-switch figure.
- Both rows print one unit, full 8266-8999 effectivity, and unit-exchange status.
- TP42000 and 211C223-647 are separate pressure-switch records with no printed interchange to TP42001.
The export does not define GX or print an interchange with TP42000 or engine-pump switch 211C223-647. Keep the exact number, system position, and figure with the request.
