## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for General Machine--Diecron, Inc. (GMD) actuator nut assembly, part number (P/N) GMD115-810029-17 and P/N GMD115-810029-23, that are installed on certain airplanes. This proposed AD would require you to determine by maintenance records check and/or inspection whether any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on the right main landing gear (MLG) actuator, and, if installed, would require you to replace it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA-approved equivalent P/N. This proposed AD results from several reports of failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029-23. We are issuing this proposed AD to prevent failure of the actuator nut assembly for the right MLG actuator, which could result in failure of the MLG. This failure could prevent the extension or retraction of the MLG.
