Hold on a minute! I was merely answering the OP's question.
No, you are speculating an answer is more accurate.
In due course, how many of these other defective planes would have suffered the same fate as the first one? I'd wager the chances were fairly high.
Speculation.
I'd say that constitutes a major design flaw, wouldn't you?
Speculation
If the landing gear had been designed differently then it is very likely landing gear would be near 100% reliable...
Speculation
Also, it is not clear whether the two planes with corroded bolts had deficient filters or not.
If thats true, what's your point?
What is clear is that the landing gear needs investigating and potentially re-designing
.
Speculation.
