## Abstract

We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 cracking, bulging, deformation, or oil leakage in the lower lid of the landing gear emergency accumulator, which could result in decreasing the airplane's structural integrity and jeopardizing the landing gear emergency extension in case of system failure in normal mode. We are issuing this AD to require actions to address the unsafe condition on these products.
