Back in the 80’s while in the Army at Fort Richardson we called these “crash hawks”. Hated the aircraft when they started to arrive. It was always to do with the chip detectors that caused us the biggest issue. But like you we had a full down stabilizer issue on one flight but luckily we were just at a close hover and able to drop to the tarmac without any further issue. We were plain lucky. So no more flying in the Blackhawk instead I went back to the Huey’s crew.
