Narrative:

Shortly after departure from lax on climb out, I noticed a status message on the lower EICAS screen, 'landing gear monitor,' and notified the captain. Consulting the aircraft manual we found no reference to this message and after checking the landing gear indicator lights we continued on to phl. Upon arrival in phl we encountered low visibility in light rain and fog and light to moderate turbulence on the approach with a strong tailwind on the base to final leg. After parking at the gate a mechanic informed us that a fairing panel on the right main gear was missing. We assumed it had come off on our departure from lax due to the EICAS message. Shortly thereafter, we were informed the panel had been located in the back yard of a residence off of the airport property in phl. The subsequent flight was cancelled and we ferried the aircraft to heavy maintenance in clt. Supplemental information from acn 230966: after checking all gear lights out, gear up and locked and going through a light test we decided that maintenance in phl could do the bite test as this aircraft in previous 2 weeks had 6 occasions when the status message, landing gear monitor came on. On arrival phl and after check exterior of the aircraft, we found 1 of the gear doors missing.
