description An aircraft (101) including a nacelle (200) disposed at a fixed location relative a wing member (109); a proprotor housing (202) coupled to the nacelle (200), the proprotor housing (202) configured to selectively rotate between a horizontal orientation and a non-horizontal orientation; a door (204) pivotably coupled to the proprotor housing (202); and a linkage (213) to connect the door (204) and the nacelle (200), the linkage (213) configured to move with the door (204) from a closed position when the proprotor housing (202) is in a horizontal orientation to an open position when the proprotor housing (202) is in a non-horizontal orientation. In some embodiments, there can be a hinge member (208) for hingedly coupling the door (204) to the proprotor and/or nacelle (200). In other embodiments, the door (204) includes a flexure portion (704m, 704n). In some embodiments, the nacelle (200) includes a plurality of doors (804). In other embodiments, proprotor includes a forward portion and a stationary aft portion; wherein the forward portion is configured to selectively pivot.
