18 Check ECAM for “ENG i MINOR FAULT”19 Ground scanning followed by removal of RVT KS1, followed by Ground Scan, then refit. Then similar for RVTs KS2 - KS4. If no maintenance messages are generated,

then carry out the Thrust Reverser Test.20 Examine the outer surface of the pivot doors to see if they align with the outer surface of the fan cowl doors. If they are aligned, perform a Ground Scan.

If no maintenance messages are generated, carry out an Engine Test: Thrust Reverser Test.
