4. Pull and tie off 5 amp (115 volt) circuit breaker for control unit power (in cockpit).

5. Make notation in aircraft logbook regarding deactivation of the proximity floor lighting system.

B. Within 90 days after the effective date of this AD accomplish one of the following:

1. Replace the system with another FAA-approved system; or,

2. Altitude pressure relief hole areas that are found to be blocked must be cleaned.
