The fact is that the R22 is a very competent mustering machine. It would not be used by so many operators both commercially and privately relatively incident free if this weren't the case. The problem is that Frank Robinson is is trying to boost his profit margin. Only a few years ago belts would go the full 2000 hours. I have heard of a case where a set of belts went upwards of 3000 hours. These were the days before you could scrunch up a set of belts to fit in your palm. Now, why else would Frank go away from a proven design to something that now only lasts 500 hours (maximum). Same goes for the A029-1 tail rotor blades, they were lifed at 5525hrs. Now for the same money, you can get a set of -2 blades that will last 2200hrs. Genius. RVDT, only 2 factors really affect the sheave alignment. Engine mounts, which will sag when new and then gradually over time, and the belts, which will stretch and do the same. Aligning the sheaves and checking the clutch shaft angle is not a difficult thing to do. Also, if Frank only covers the R22 for personal use, why does he sell a Tuna Boat bubble cover? I personally can't wait for Frank to kick the bucket and let some new blood flow through the company. With his stubbornness and tight fisted mindset, it is only a matter of time before more pilots are killed due to these problems which should have been sorted out decades ago.
