The FAA last week warned aircraft operators of potential problems if they had their McCauley constant speed propellers serviced by Sensenich Propeller Services, Inc., North Windham, Connecticut. The agency says the company was re-installing equipment without fully following the recommended methods, techniques, and practices prescribed in the current McCauley constant speed propellers maintenance manual. The agency said the safety alert – SAFO 19002 – applies to all propellers serviced by the Connecticut company that previously held FAA Air Agency Certificate No. Q0PR011X for an overhaul of propeller assemblies. The online link to the Windham Connecticut facility was no longer listed on the Sensenich website, nor was the company’s website operating.
