A severe hailstorm smashed through Denver International airport on Wednesday 21 June, catching aircraft on the ground during the evening connection bank. Nine of Air Wisconsin‘s eighteen BAe 146s were damaged by the golfball-sized hailstones, as were six of its Do 328s and four of its CRJ-200s, causing substantial flight cancellations in the following days. Air Wisconsin dispatched teams of maintenance personnel to inspect and repair the damaged aircraft, and expects to return them all to service by Sunday. Air Wisconsin operates all its aircraft on United Express services. It recently placed an order for 75 Bombardier CRJs, to allow it to expand its operations. It is also considering its options to replace its 146s, and is looking closely at the Avro RJX. The BAe 146, Avro RJ, and RJX are the only jetliners able to operate on Air Wisconsin’s key Aspen-Denver market.
