Abstract: A method for installing a pre-assembled powerplant and pylon assembly on an aircraft comprises determining a first length of a first link, determining a second length of a second link, determining a first distance occupyable by the first link between the pylon and the aircraft, determining a second distance occupyable by the second link between the pylon and the aircraft, determining a first result by subtracting the first distance from the first length, determining a second result by subtracting the second distance from the second length, and determining a third result by adding the first result and the second result. If the third result is less than or equal to zero, the first link is installed between the pylon and the aircraft before the second link. If the third result is greater than zero, the second link is installed between the pylon and the aircraft before the first link.

Abstract: Aft fairings for aircraft pylons are disclosed. In one example, a fairing includes: two opposite side panels extending generally along a longitudinal direction of the fairing; a plurality of transverse ribs interconnecting the two opposite side panels; and a heat shield for exposure to a primary flow of an aircraft engine. The heat shield includes transversely opposed side end portions and a mid portion disposed between the transversely opposed side end portions. The heat shield is secured to the ribs via the mid portion of the heat shield. The transversely opposed side end portions are permitted to move outwardly from the mid portion due to thermal expansion of the heat shield.
