Marine Corps Times is reporting that the entire Marine fleet of MV-22 Ospreys has been temporarily grounded due to a computer chip problem:
The problem was diagnosed during the pre-flight test of an Osprey at Bell Boeing’s Amarillo, Texas, facility, he said.
Ospreys are equipped with three flight control computers — a triple redundancy system in which each computer serves as a backup to the other should one of them malfunction. The chip in question is responsible for switching over to a backup computer. Testing found that, in extremely cold temperatures, the chip fails to perform that particular function.
Marine Medium Tiltrotor Squadron 263 will be the first operational Osprey squadron to deploy. It’s scheduled to ship out later this year, destination TBD.
