Summary
We propose to adopt a new airworthiness directive (AD) for Slingsby Aviation Ltd. Model T67M260 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 cracked horizontal stabilizer attachment brackets, which could lead to separation of the horizontal stabilizer and result in loss of control. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
