Summary
We propose to adopt a new airworthiness directive (AD) for EVECTOR, spol. s.r.o. Model L 13 SEH VIVAT and L 13 SDM VIVAT gliders (type certificate previously held by AEROTECHNIK s.r.o.). 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 lack of distinct color marking of the elevator drive. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
