Users of military aircraft often discover that equipment and systems on their platforms are no longer supported by the Original Equipment Manufacturers (OEM). Having developed upgraded equipment and systems, the OEM may find it impractical to continue to provide repairs and support to the older model and may suggest that users upgrade to the newer system. Budget and scheduling constraints may make it difficult to perform timely system upgrades. Operators of these platforms may exhaust their equipment spares, limiting their usage for critical mission operations. To prevent this, users can use third party repair sources, restoring the spare equipment pool and thereby providing additional time to obtain budget and schedule OEM suggested upgrades.
Advanced Testing Technologies Inc. (ATTI), a manufacturer of Automatic Test Equipment (ATE) and developer of Test Program Sets (TPSs), has developed test and repair capability for hundreds of Line Replaceable Units (LRU) and Support Replaceable Units (SRU). As a developer of TPS and repair capability, ATTI has secured a library of support documentation, specifications and manufacturers data. Through analysis and reverse engineering, ATTI has developed an unparalleled knowledge of hundreds of LRUs and SRUs on the E-3 AWACs, C-130 and other military aircraft. Our TPS and repair capability gives us first hand knowledge and experience with Radar, Radio, and Intercom systems and well as flight instruments such as Altimeters, Airspeed and Heading Indicators and Inertial Navigation equipment.
ATTI maintains a library of technical data that includes OEM drawings, technical orders, critical item specifications, and test specifications for thousands of LRU and SRUs on airborne platforms.
ATTI is expert at locating hard to find and unique parts necessary for the repair and manufacture of airborne equipment. This has enabled us to successfully repair equipment that otherwise might have been deemed unserviceable due to lack of parts availability. In some cases, ATTI has built entire Circuit Card Assemblies to the original specification using OEM parts and PCB design data. We have repaired hundreds of avionic circuit cards, assemblies, and avionic LRU’s. We have performed repairs for the US Air Force, US Navy, private companies and many Foreign Military Sales (FMS) customers.
In addition to repairs, ATTI has experience in building replacement SRUs for airborne equipment. When the OEM indicated that the items were obsolete and no longer supported, ATTI successfully manufactured new SRUs for the Vertical Deflection Amplifiers P/N 130211-10 and Video Processor P/N 130209-10 for the AWACS Color Monitor. The illustrations below depict two (2) Vertical Deflection Amplifiers: an original Hazeltine manufactured SRU, and an SRU built by ATTI to the original drawings and specification.
ATTI’s expertise in test, repair and manufacturing provided the customer with the means to maintain and repair their aircraft when the OEM would no longer provide support.
