Résumé
This document proposes to supersede Airworthiness Directive (AD) 86-22-09, which applies to Univair Aircraft Corporation (Univair) Models (ERCO) 415-C, (ERCO) 415-CD, (ERCO) 415-D, (ERCO) 415-E, (ERCO) 415-G, (Forney) F-1, and (Forney) F-1A airplanes. AD 86-22-09 currently requires you to inspect the fuel line nipple for damage and replace any suspect part. AD 86-22-09 resulted from reports of failures of the fuel line nipple caused by improper installation or incorrect alignment. This proposed AD would require you to accomplish the following on airplanes with the gascolator connected to the side of the carburetor: Replace any aluminum fuel line nipple with a brass or steel fuel line nipple, inspect for the existence of double support tubes on the gascolator, and install these tubes if they do not exist. The proposed AD would not affect those airplanes with the gascolator mounted on the firewall. The proposed AD is the result of incidents where the fuel line nipple failed on the above-referenced airplanes. The actions specified by the proposed AD are intended to prevent failure of the fuel line nipple or the gascolator because of the current airplane design configuration (aluminum
