Airworthiness Issue For Airplane Pilots And Mechanics That Are Being Impacted By The Canadian Wildfires

ATTENTION: Airworthiness issue for airplane pilots and mechanics in Wisconsin and any other areas that have had their visibility impacted by the Canadian wildfires. Wausau Flying Service has had three (3) airspeed indicator (ASI) failures in the last four (4) days on three (3) separate aircraft. All failures were detected during takeoff roll and all takeoffs were aborted before becoming airborne. Upon inspection by our mechanic, each aircraft pitot tube was packed with what appears to be ash which caused the failure. Don’t be surprised if it happens to you if you’re flying an airplane that has flown a lot recently under these smokey conditions.
