The status messages page shows after you select the MAINT button. The status messages page gives information to help analyze aircraft airworthiness. The STATUS MESSAGES page can show 28 messages on one page. If more than 28 messages show, select NEXT PAGE to show page 2.
Cross Reference List
A Cross-reference list of status messages and corresponding MEL items is provided in the operator’s MEL. The Cross Reference List is intended to assist operators in quickly identifying the proper MEL item to consult for possible dispatch relief. Only status level messages are listed in the Cross Reference List. Maintenance level messages are not included in the Cross Reference List, since they do not affect the airworthiness release of the airplane.
Status Message and associated MEL
Appropriate MEL items are given for each associated message displayed. Status messages that do not have a specific MEL item to allow dispatch are listed with one of the following cross-references:
- N/A – Not Applicable: There is no MEL item listed because the message does not indicate a system failure.
- None – There is no MEL item for the failure condition indicated by this message.

Dispatch with Status Message
Any monitored faults that affect airplane dispatchability will have a flight deck alert or a status level message, with a corresponding correlated maintenance message. System faults displayed at status level should be resolved by MEL compliance or maintenance action prior to engine start.
After engine start, flight deck alerts are the primary means of alerting the crew to non-normal conditions or improper configuration. Display of flight deck alerts requires accomplishment by the flight crew of any applicable steps in the appropriate non-normal procedure. Conditions which can be resolved by flight crew action may allow continued normal operation. For system faults, following completion of the non-normal procedure and prior to takeoff, the operator’s MEL should be consulted to determine if relief is available for continued operation.
Note: The above status messages and related MEL items are for reference only.
