A sad, most unfortunate accident. We like to think that vendors follow specs. meticulously and that QA catches errors but we know this is not always true. Without jumping to more conclusions it is worth noting that Bell put out their ASBs, Transport Canada got an emergency AD published and the USFS did what it could but nothing from the FAA to alert operators and ground the machines until inventories are checked and records searched to see if more of this batch of pins are in service. Well, with the 4th of July and all, I guess we shouldn't expect anyone at the desk until this morning.
