Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain HOAC AUSTRIA GmbH (HOAC) HK 36R ``Super Dimona'' gliders. The proposed action would require inspecting the exhaust system for corrosion, replacing the exhaust system if corrosion is found, and installing a carbon monoxide detector. Reports received by the Federal Aviation Administration (FAA) of severe exhaust system corrosion on the affected gliders, including one of excessive corrosion (rusting through), prompted the proposed action. The actions specified by the proposed AD are intended to prevent carbon monoxide leakage caused by a corroded exhaust system, which, if not detected and corrected, could lead to passenger injuries.
