## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain GROB-WERKE Model G120A airplanes. This proposed AD would require you to replace the main landing gear (MLG) up-lock hook assembly. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to prevent the MLG from becoming jammed and not extending, which could result in loss of control of the airplane during landing.
