I used to work on VC10s at Brize Norton. The aircraft would often spend a couple of days between filghts and every de-brief brought us a dozen defects [or snags as they were called in the RAF]. Then came the Turkish invasion of Cyprus. We had all spare aircraft flying round-the-clock evacuating civilian, stopping only for fuel and the occasional wheel change. [This is of course how they were designed to be used}. We were dreading the workload when they eventually finished the evacuation. Surprise, surprise! - when the evacuation ended we had only three snags to clear across the lot of them. Airliners like to fly and as long as they keep flying, the avionics kit gives very few problems.
