Human Factors; Aircraft; Procedure
We were repositioning an aircraft from ZZZ-ZZZ1 and we got a 'RAT FAIL' message on landing. Maintenance was notified and it was written up. We then learned that the circuit breakers were out on the MCDU (Multi-purpose Control Display Unit); meaning we failed to check the status of the circuit breakers on the MCDU during the originating/receiving checklist. While we had thought we checked it when we got on the airplane; it seems we had missed it and didn't get a message alerting us until we landed. Factors that caused this omission included falling into the bad habit of thinking things have been checked even if they haven't; rushing through checklists without making sure the steps have been completed; and tiredness from an early morning show with 2 repositions with maintenance and bad weather. Because we frequently hit the CB button on the MCDU; it's easy to think you've already looked at the page and verified it has been done; because of complacency. The reason there are 2 pilots is to catch each other's mistakes. Today we missed an important part of a checklist that didn't result in any safety concerns for today; but easily could have been a problem if other issues arose. For next time; I will remember to slow down and make sure each checklist item is completed; instead of getting in 'autopilot' mode and thinking things have been done before they have. There are no suggestions for any procedure changes as this was a simple accidental omission of a checklist item that should have caught the problem.
