## Summary

We propose to adopt a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SR22T airplanes. This proposed AD was prompted by reports of partial loss of engine power due to a dislodged rubber gasket/seal being ingested into the turbocharger. This proposed AD would require inspection and modification of the air box flange welds and slots and installation of induction system air box seals as applicable. We are proposing this AD to correct the unsafe condition on these products.
