AD 95-17-06 60 FR 47864

This amendment adopts a new airworthiness directive (AD) that applies to Mooney Aircraft Corporation (Mooney) Model M20K airplanes with a Continental TSIO-520-NB engine installed in accordance with Supplemental Type Certificate (STC) SA5691NM. This action requires repetitively inspecting the exhaust transition tube and turbo mount assembly for cracks, and replacing any part found cracked. A report of a cracked exhaust transition tube that connects the exhaust manifolds to the turbocharger inlet on one of the affected airplanes prompted this action. The actions specified by this AD are intended to prevent exhaust gases from entering the cabin heating system because of a cracked exhaust transition tube, which, if not detected and corrected, could result in hazardous levels of carbon monoxide in the airplane cabin.
