Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Blanik Limited Models L-13 Blanik and L-13 AC Blanik gliders (type certificate previously by LET Aeronautical Works) that would supersede AD 99-19-33. 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.
