ABSTRACT:
A strut construction for holding aircraft cowlings in a raised position, comprises first and second telescoping members which are relatively shiftable between a collapsed inoperative strut position wherein the members are nested together, and an almost fully extended operative load-bearing position wherein the members are only partially nested, the relative shifting of said telescoping members to their partially extended operative position causing a blocking of any collapsing movement. The strut has a spring-charged collar which is slidable on one telescoping member between blocking and unblocking positions, and the collar has a latch which is responsive to its manual shifting to its unblocking position against the spring-action thereof, for holding the collar in an unblocking position. Such shifting unblocks the telescoping members, thereby to enable them to be relatively shifted to their collapsed position only after the cowling has first been raised to the full extent of its movement.
