A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

We propose to adopt a new airworthiness directive (AD) for all Honeywell International Inc. TFE731-20 and TFE731-40 turbofan engines. This proposed AD was prompted by two fan disks found with a manufacturing-caused flaw. This proposed AD would require removing affected fan disks, performing a one-time inspection, and replacing fan disks that fail inspection. We are proposing this AD to correct the unsafe condition on these products.
