The FAA is investigating a report of a power lever failure on a Cirrus SR20 airplane. While advancing to full throttle in preparation for takeoff, the power lever sheared and the pilot aborted the takeoff. The fleet operator inspected additional aircraft and found cracks in numerous levers through visual and dye penetrant inspections. The aircraft hours on the fleet ranged from 2900 to 3900 hours. The aircraft are utilized in a training environment and contained an average of 12,000 to 15,000 landings.
FAA’s Operational Safety Branch recently issued an Airworthiness Concern Sheet (ACS) to highlight this concern and the ongoing investigation including photographs of the failed and cracked parts. The FAA is recommending operators inspect the power lever on Cirrus SR20/SR22/SR22T airplanes and provide information including description of damage, available photos, airplane serial number, time in service, and any prior replacement of the throttle assembly or power lever.
