## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASH 26E sailplanes. The proposed AD would require inspecting the red silicone tube of the rotor interior air cooling (just in front of the carburetor) for oil leaks and the heat damping layer of the lower exhaust damper fairing for oil contamination, and replacing the applicable parts where oil leakage or contamination is found. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed AD are intended to detect and correct any oil-contaminated exhaust damper fairing caused by oil leakage in the red silicone tube of the rotor interior air cooling, which could result in an exhaust fire and/or an explosion.
