I traveled with Delta recently, and we were flying a 767-432ER (N842MH) from ATL-FLL. I noticed however, that when the 764 pulled into the gate, the nose gear doors had not retracted completeley....meaning they were not flush with the fuselage, but potruding a bit. (Lol, and for you joksters, it wasnt the ones that are open where the gear sticks out, but the 2nd pair of doors, that open and close when the gear must be extended or retracted.) Does anybody know why this could be?
p.s.- I apologize for not having a picture of it

Standard for the 767, the nose gear doors protrude a couple of inches with the gear down.

On all Boeings the nose gear doors close different when the gear is down, then when the gear is up. In flight the doors will be flush....(if everything is rigged right)....

I shouldn't have said "all Boeings" the 747 has an hydraulic nose gear door actuator so it closes the same way with the gear up or down. Some doors will droop when hydraulic pressure is off.

It seems most all airliners with mechanical linkage nose gear doors exhibit this trait. Two non-boeing planes that also do this are the ATR-72 and DC-9/MD-80 family. I've even seen some aircraft with placards installed on or near the nose doors to notify well-meaning, but uninformed pilots and mechs that nothing is amiss.

does the nose gear help to keep the doors flush when retracted?

Futureualpilot, from what I can establish the brace strut that runs down to the nose gear does not allow the doors to close fully, although I have been unable to get a good explaination. I actually asked an engineer when I took this photo as the new paint made the gap stand out more!

Given there's a new thread on this topic, it should be okay to bring this thread back to the top.
