I just noticed this incident but did not see it discussed here.
Commutair / United Express Embraer ERJ-145 (N16911, built 2001) received damage during a ground engine test a Kingman AP, AZ (KIGM) when it accidentally surged ahead hitting two vehicles seriously injuring a ground worker.
I searched FR24 but did not see this bird doing any commercial flights recently. Was this just a test flight to retrain the pilots?
