Abstract:

The APSCB-1 (Adjustable Pin Spanner Cross Beam) is essentially a type of spanner wrench. It was designed for use primarily on specific multistage aircraft jacks (12-ton and 25-ton Columbus jacks). The reason for this design (originally for U.S. Military Aviation) is because a typical spanner wrench would not appropriately distribute nor deliver the required force to break loose any bronze bushing when servicing or repairing a leaking ram seal. The bushing would often be taken off by a hammer and a punch (because they would be so badly seized on there) and would be heavily damaged as a result every time. Often times, the maintenance technician would literally have no other way of getting the bronze bushing loose, and the lack of a specialized tool to do so. The other problem was that these bushings aren’t cheap, they run about 600 dollars a piece. As if that wasn’t enough, several man-hours are wasted in the removal of a bushing by force without a proper tool. In one real life instance, a bushing was placed on order as the damage on removal attempts was excessive, after a cumulative total of 60 (yes 60!) on the work order. So doing the math here, if the average technician is making 25 per hour, and 60 hours were wasted, thats already at a $1,500 dollar loss (not including the completely unnecessary replacement of the bushing which adds roughly another $600 dollars AND having to wait an entire month for it to come in. The APSCB-1 was then designed with a Six Sigma approach, where a single tool, adjustable for all size  bronze bushings on all stages of each jack, and rugged enough to apply serious torque without damage to the tool or the bushing. Once prototyped, it was tested by a group of Marine maintainers, where one had to stand on it and a ½ inch breaker bar and a fence pole added onto it for leverage on a stubborn bushing, which they were then able to break it free with minimal effort. Zero damage was noted on the tool and the bushing after applying such force. The APSCB-1 can be configured in a two point or four-point pattern for application. The force from a breaker bar is distributed from the center of the tool to all points evenly. A standard spanner wrench has force applied to a bushing from an offset position, not to mention added friction against its pivoting point near the handle base. It's design and construction is aimed at being a "one-time" buy item, so long as it is used appropriately for its intended purpose, should outlast the user.

Real-world application feedback:

Several aircraft tripod jacks in a downed status were repaired rapidly, and something unheard by many GSE personnel also resulted from this tool, and that being several BCM (Beyond Capable Maintenance) jacks that were slated for DRMO (Defense Reutilization Management Office) which basically means trash being auctioned off that is no longer servicable for aviation were pulled from BCM status, repaired, and turned to an RDI (Ready For Issue) status. The cost of this tool paid iself almost 40 fold in two weeks, and an estimated savings and loss prevention of roughly 200,000 dollars.
