After fatigue penalty factors were applied for running landing, wingover etc, it was found that people had been operating the aircraft out of manufacturers guidance for many years.
that happened with many military helicopters as their use and hours matured, they were being used for military sortie profiles and not civilian ones and since the manufacturers couldn't have known in advance exactly how the aircraft were going to be used then its not a surprise. The Mil operated them within the Release to Service which the manufacturer had sight of so everything was legal.
Operating outside their guidance and operating outside the RFM (RTS) are not the same thing.
