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

Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2022-19-03, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes. AD 2022-19-03 requires incorporating new revisions to the airworthiness limitation section (ALS) of the existing airplane maintenance manual (AMM) or Instructions for Continued Airworthiness (ICA) to establish a 5-year life limit for certain main landing gear (MLG) actuator bottom attachment bolts and new life limits for the rudder bellcrank. Since the FAA issued AD 2022-19-03, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the ALS section of the existing AMM or ICA for your airplane, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The resulting AD
