Plain English Summary

3/10 complexity

Operators of specific Cessna 550 and S550 serial-numbered aircraft must pull and disable circuit breaker CB275 (indirect fluorescent cabin lighting) before the next flight to remove a wiring mismatch hazard. This is mandatory for affected owners/operators and maintenance personnel.

The directive ties termination to compliance with the listed Cessna service bulletin wiring changes; completing the SB restores the circuit and ends the AD requirement.
