## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited (Viking) Models DHC-6-1, DHC-6-100, DHC-6-200, DHC- 6-300, and DHC-6-400 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as occurrences of excessive wear of elevator cables at pulley location station (STA) 270.3. The FAA is issuing this AD to require actions to address the unsafe condition on these products.
