One of the lingering issues following on the March accident seems to be why, after the Broome incident, was there such an apparent delay allowed before the problem had to be addressed in the field by means of the bolt changeout.
Now we have a MGB mounting lug that has had cracks appearing, first noticed at the beginning of this year, and as I understand it, the cause has not yet been determined.
The OEM has however stated "Analysis shows the aircraft can operate safely for a minimum of 10 hours, even assuming a full mount fracture and resulting worst-case stresses". I suppose one can probably assume this is where the "10 hours" came from in the current inspection interval.
Even if you have absolutely no doubt whatsoever that the manufacturer was able to replicate all possible known full mount fracture and resultant worst-case stress scenarios during their analysis and that 10 hours is the number, given the potential consequences if further damage were to occur after one mount had been fully fractured, why on earth would you not mandate that until the cause is identified the inspection be done before every flight ?
Is it time to put the calculators down and start doing, let's call it AMARPAMM (As Much As is Reasonably Practical And Money doesn't Matter) until cause/s of any incidents with potentially catastrophic consequences are conclusively dealt with ?
