## Discrepancy

(CAN) AIRCRAFT WAS SNAGGED THAT IT LOST ITS HEADING INDICATION MOMENTARILY DURING FLIGHT AND THAT IT HAD A GDL90 FAILURE. THE AIRCRAFT IS G1000 EQUIPPED AND IS AT S/W VERSION 563.35 (LATEST CESSNA S/W) DONE IN FEB 2018. WE ARE UNABLE TO REPLICATE THE ISSUE ON THE GROUND. WE RE RACKED THE GIA`S AND TRANSPONDER.
