Abstract
An adjustment tool is provided including a block having a plurality of sides including a first side and a second side. A hole is formed in the block such that a first distance between the center of the hole and the first side is different from a second distance between the center of the hole and the second side. The first distance corresponds to a first standard size component and the second distance corresponds to a second standard size component.
Claims9
A connection assembly for mounting a cowl door to an airframe, the cowl door being movable between a closed position and an open position, comprising:
- a first fitting extending from the cowl door;
- a first connection member having a first end and an elongated second end arranged at an angle to the first end, the first end being coupled to the first fitting, and the second end including a bushing assembly;
- a second connection member having a first end and a second end, the first end being operably coupled to a portion of the first connection member and the second end being connected to the airframe, wherein a size of the bushing assembly is adjustable such that when the cowl door is in the open position, the bushing assembly is configured to contact an adjacent surface of the second connection member to limit movement of the cowl door.
A method of adjusting a connection assembly coupling a cowl door to an airframe, the connection assembly including a first fitting extending from the cowl door, a first connection member coupled to the first fitting and the second end including a bushing assembly, and a second connection member operably coupled to a portion of the first connection member and the airframe, the method comprising:
- aligning a hole of an adjustment tool with an opening formed in a free end of the first connection member;
- rotating the adjustment tool until one of a plurality of sides of the adjustment tool is in contact with a surface of the second connection member to identify a measured distance;
- and
- installing a bushing assembly into the opening in the free end of the first connection member, the bushing assembly having a radius substantially identical to the measured distance.
