Aircraft involved

Probable cause & findings

The airplane’s collision with a bird during short final.

Factual narrative

The operator's director of safety reported that, during short final, the pilot quickly maneuvered the airplane to avoid a bird. When the pilot rolled wings level, a second bird went through the propeller and struck the horizontal stabilizer. The pilot then landed without further incident. The airplane sustained substantial damage to the left horizontal stabilizer. The director of safety reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
