Summary
We propose to adopt a new airworthiness directive (AD) for GROB-WERKE Model G115EG airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 elevator trim tab arms on several Grob G 115 airplanes, which could result in failure of the part and consequent loss of control. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
