The FAA's summary their words, unchanged

We are adopting a new airworthiness directive (AD) for certain GROB-WERKE Models G115EG and G120A airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks in the left hand elevator flange. We are issuing this AD to require actions to address the unsafe condition on these products.
