From the report
A total of 299 files containing data from the MaxLife system were recorded, providing information on 350 hours of R22 operations. AeroStructures reported that these 350 hours accounted for around 55 per cent of the total hours operated by this helicopter over the 26 weeks of the study. AeroStructures could not determine the reason for the difference between the total number of hours the aircraft operated and the number of hours recorded by the MaxLife system, but concluded that the 350 hours of MaxLife data provided a suitable basis for further analysis.
Well isn't that convenient? only just over half the hours flown ended up recording data which then just comes within what Frank deems acceptable for the aircraft.
The phrase 'whitewash' comes to mind since Frank isn't going to complain when he sells so many helicopters to the mustering fraternity.
In many other helicopter operations, the fitting of HUMS/HOMP is mandatory - why do I get the feeling this is conveniently ignored in the mustering game because the real picture of abuse of an airframe not designed for the job would emerge?
