Lufthansa engines

Challenge

Lufthansa Technik chose the MK automatic test system to enable the complete electrical system testing of a range of aircraft engines passing through their MRO facilities worldwide. The test systems’ ability to hold programmes for, and test a full range of engines by simply changing the interface connection between tester and engine makes the MK system an ideal MRO solution.

The MK system tests the electrical harnesses on the engine, and then performs function testing of the relays, solenoids, sensors and igniters. All test and result data is then logged and delivered as a report which can be delivered as proof of test to the final customer.

Each test system is used to test the following range of engines at LHT:
CF6-50 ; CF6-80C2 ; CF34 ; CJ610 ; CF700 ; CFM 56-2 to –7 ; TFE731 ; Trent 500 ; RB211-535E4 ; JT8D ; JT9D ; JT15D ; PW4000 ; PW100 ; V2500.
