The USAF became aware of numerous instances of cracked P-23 cast iron hub assemblies and began monitoring these cracks in late 1996 and early 1997. In March 1998, the USAF issued a "restriction notice" for all P-23 vehicles, restricting P-23 vehicles to speeds no greater than 30 miles per hour (mph) during emergency operations, and no greater than 15 mph for all non-emergency operations. Several attempts were made to upgrade the hub assemblies, but failures continued to occur.
