Dear Boeing lovers,

Here I stand to ask you about problem "Lavatory Smoke's CB pops out prior after landing". The summary of troubleshooting as follows:

* All lavatory smoke detector replaced.
* Lavatory Smoke's CB replaced.

The problem still exist, after landing the CB always pops out. On ground system test of each detector was normal.

Please kindly share ur experience if u had this problem, or ur suggest will be the most helpful for us.

Warm regards,
Novansky.
