## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Continental Aerospace Technologies, Inc. model GTSIO-520-C, GTSIO-520-D, GTSIO-520-H, GTSIO-520-K, GTSIO-520-L, GTSIO-520-M, GTSIO- 520-N, IO-550-G, IO-550-N, IO-550-P, IO-550-R, IOF-550-N, IOF-550-P, IOF-550-R, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, TSIO-550-G, TSIO-550-K, TSIO-550-N, TSIOF-550-D, TSIOF-550-J, TSIOF- 550-K, and TSIOF-550-P reciprocating aviation gasoline (AvGas) engines with a certain cross-flow cylinder assembly installed. This proposed AD was prompted by reports of in-flight engine failures due to fractured cross-flow cylinder assemblies. This proposed AD would require visual inspection and, depending on the results of the inspection, modification or replacement of the cross-flow cylinder assembly. The FAA is proposing this AD to address the unsafe condition on these products.
