During landing, the CFI was flying the aircraft from the right seat. The aircraft departed the runway to the right, even though the pilot applied full left rudder.

An investigation revealed that the left rudder pedal (Storable Pedals) unlocked when firm pressure was applied. Further inspection revealed the bellcrank (P/N 1260021-1) was bent. (Refer to the illustration.)
                
The submitter did not have any explanation for why the bellcrank bent.
