Notice Number: NOTC2904
FAA AD 2023-04-08 - Continental Engines - Superseded for Missing Engine Models
This posting will be removed on
Saturday, April 13, 2024

Since the FAA issued AD 2023-04-08, the FAA determined that IO-470-A, -C, -F, and -LO; and TSIO-360-F and -FB model engines are also affected by the unsafe condition and should be added to the applicability. Additionally, the FAA determined that the limitations in the special flight permit paragraph, specifying “no metal contamination in the oil filter”, did not account for trace metal particles that may be found in newer engines due to break-in of the engine.

AD 2023-04-08 is superseded by AD 2023-05-16 to include the additional engine models in the applicability and to revise the special flight permit limitations.  AD 2023-05-16 went on Public Inspection on March 13, 2023 and is scheduled to publish on March 15, 2023.

You may find the new AD at www.federalregister.gov by searching for AD 2023-05-16.

  • AD 2023-05-16 did not change the required action paragraph to what is found in AD 2023-04-08.
