The FAA has received multiple reports from the field of cracked cylinders despite prior compliance with AD 2020-16-11. The FAA is concerned that the corrective action contained within AD 2020-16-11 is not sufficiently resolving the issue, so the FAA needs additional input from the field in order to better understand whether any additional actions are necessary at this time.
