Our clean line operators are very knowledgeable in base alloys, chemical reaction times, mixtures, operating
temperatures and numerous specific procedures to avoid damaging or contaminating components. In addition to our state of the art parts washer, a number of different chemicals are utilized
within this department. The properties of these solutions are utilized in removing chemical films, bond coating, metal spray, sulfidation, and oils. Samples are analyzed to ensure
that the chemicals are within optimum parameters.

A number of blast cabinets employ a wide variety of blast media, including silicon carbide, aluminum oxide, glass and
plastic beads, nickel blast and shot peen, and are strategically located throughout the facility.

We have a fully equipped FPI NDT line. Radiographic, ultrasonic and magnetic particle inspection facilities are also
available as required.

Our Weld Department has four fully equipped stations utilizing Miller Syncrowave Models 350, 300 TIG, 200 MIG welders,
and Dual Pulse spot welder. Our technicians are fully certified to work with the superalloys used in many aerospace parts, as well as the more common steels, magnesium and aluminum. Laser and
plasma arc welding can also be provided.

Our state of the art booth employs Miller and METCO Plasma spray equipment including Miller twin arc spray system to
apply both nickel based and aluminum thermal sprays. Ceramic thermal barrier coatings processes are also available. Samples of our thermal spray are regularly metallurgically evaluated to
ensure the coatings meet or exceed our quality control specifications.

We have the capability to apply and diffuse silicon modified aluminide high temperature aerospace coatings. Platinum
aluminide and other high temperature aerospace coatings processes are also available.

Heat Treating is critical in the overhaul of aerospace components. Stress relief and age anneals are often required to
return a component to airworthiness standards. Our procedures are fully compliant with industry standards and followed precisely. Full documentation of furnace charts, load lot runs, and
conformance criteria are retained for future reference. Our ovens are calibrated regularly to ensure precise temperatures and equal heat distribution throughout the internal chamber.
Operators monitor thermocouples which are placed in key areas inside the chamber and are tied to precise charting equipment to measure and document temperature. These charts are then
compared to standards set by engineering and the run is approved by quality assurance.

Our hand finishers perform intricate operations that are virtually impossible to perform with automated machines.
Hand Finish is one of the areas in component repair where art and science are seamlessly blended. Hand Finishing is utilized throughout the rework cycle because the overall quality of the
finished piece is rightly enhanced by paying attention to these details. The great expertise and experience of our hand finishing staff expedites parts through the rework cycle.

Our braze department is a leader in the industry and uses proprietary braze processes developed by our FAA/DER. We
utilize two in house Vac Aero and Abar-Ibsen vacuum ovens to ensure the highest quality with very fast turn times. Samples of our braze are regularly metallurgically evaluated to ensure that the
quality meets or exceeds our strict specifications.

Our machine shop is highly computerized, using three CNC lathes, two CNC vertical machining centers and one CNC EDM in
our repair process. Our philosophy is to not merely repair parts, but to restore many dimensions to the manufacturer's print. The vertical machining centers are used primarily for gearbox
and diaphragm repairs. Most repairs are already stored in the memory of our computer, shortening turn times substantially. In addition to the CNC equipment we utilize eleven
conventional lathes and ten mills.

When required, nozzles and stators are dynamically tested on our state of the art computerized Fleming and CCDI air
flow comparators to ensure that the air flow through the nozzle falls within OEM requirements. We have two comparators, large and small, to enable us to accurately measure air flow on a
very wide range of nozzles and stators. Our trained operators utilize master nozzles calibrated by the OEM. Our customers can rely upon our parts to meet operation requirements.

The final step in the rework process is the most critical. After the component completes the rework cycle, it
must be accepted in accordance with FAA approved inspection criteria, including OEM Inspection and Rework Manuals and FAA/DER approved repairs. To ensure precise dimensional accuracy our
inspectors use a computerized coordinate-measuring machine when measuring our parts. Only after it has been determined that the component meets these strict criteria, is it then signed and
tagged by the Quality Assurance Inspector. The component is then preserved in the proper manner, packed for shipment and returned to the customer.
