Why Aviation MRO Teams Choose ABI
Aviation MRO teams face long OEM turnaround times, repeated No Fault Found returns and avionics platforms that remain in service long after documentation or supplier support becomes limited. BoardMaster provides Power ON and Power OFF PCB diagnostics to help technicians investigate faults at component level, while RevEng recovers missing circuit connectivity and supports professional schematic creation. Combined with TestFlow and structured training, these systems help organisations build repeatable in-house capability, retain technical knowledge and reduce external repair dependency.
” We went from spending 50 hours to 10 minutes troubleshooting avionics assemblies with BoardMaster. “

Investigate No Fault Found Returns
Use comprehensive automatic test methods to identify circuit differences that conventional board-level checks may miss.
Keep Repairable Inventory Available
Diagnose suitable assemblies in-house to shorten turnaround and reduce dependence on external repair queues.
Recover Missing Circuit Documentation
RevEng learns connectivity from an unpowered reference PCB and produces a netlist for professional CAD schematic development.
Aviation Applications
ABI equipment supports PCB diagnostics, documentation recovery and repeatable testing across avionics, cabin systems and MRO support equipment. The following examples show where BoardMaster, RevEng, JTAGMaster and TestFlow can contribute within an approved aviation maintenance process.
Flight Control Systems
Support component-level diagnosis of flight-control computer, actuator-control and interface PCBs.
Apply comparison and Power ON and Power OFF methods to investigate intermittent and No Fault Found returns.
Avionics Displays & Instrumentation
Test analogue, digital and interface circuits within display, control and instrumentation boards.
Support maintenance of obsolete or unsupported assemblies where replacement availability is limited.
Communication & Navigation Systems
Diagnose communication, navigation and radio PCBs using complementary test methods.
Use JTAGMaster on compatible designs for boundary scan, PLD support and EEPROM programming.
Engine Monitoring and FADEC Electronics
Support bench diagnosis of engine-monitoring and FADEC-related PCBs.
Create repeatable TestFlow procedures for consistent testing and recorded results.
Cabin & Passenger Systems
Investigate PCBs used in IFE, cabin management, seating and passenger-service systems.
Support component-level repair and reduce unnecessary whole-unit replacement.
Ground Support & Test Equipment
Diagnose electronics within ground-support, bench-test and workshop equipment.
Extend the service life of assets already embedded within MRO operations.
Aviation Electronics FAQs
Answers on repairing avionics boards in-house, down to the component level.
What types of aviation electronics can BoardMaster test?
BoardMaster supports component-level testing of PCBs used in flight controls, avionics displays, instrumentation, communication and navigation systems, engine monitoring, FADEC-related equipment, cabin systems, in-flight entertainment and ground-support equipment. The appropriate configuration and test methods depend on the board design, component access and applicable maintenance procedures.
How can BoardMaster help investigate No Fault Found returns?
BoardMaster combines Power ON and Power OFF test methods to investigate and find faults that are usually missed by conventional board-level checks. Measurements can be compared with stored master data or a known-good PCB to identify abnormal components, signals and circuit behaviour. TestFlow can then capture the procedure and results for consistent retesting.
Does BoardMaster require avionics schematics?
BoardMaster can perform many component tests, V-I comparisons and live measurements without access to a complete schematic. Testing can also be based on data captured from a known-good board. When documentation is missing, RevEng can recover circuit connectivity from an unpowered working PCB and produce a netlist for professional CAD schematic development.
How much time can in-house repair save an MRO team?
Collins Aerospace reports reducing avionics troubleshooting time from 50 hours to 10 minutes using BoardMaster. In another case, the FADEC RTD test time was reduced by 50% .
