## Summary

This document makes a correction to Airworthiness Directive (AD) 2000-03-03 that is applicable to certain General Electric Company CF34 series turbofan engines that was published in the Federal Register on February 7, 2000 (65 FR 5759). Two subpart names and two mandatory inspections were inadvertently omitted from the Mandatory Inspection Requirements of Table 804. This document corrects this Table by adding the subparts and inspections.
