Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Extra Flugzeugproduktions- und Vertriebs- GmbH (EXTRA) Models EA-300, EA-300S, EA-300L, and EA-300/200 airplanes. This proposed AD would require you to seal with firewall sealant the gaps between the bottom fuselage cover (belly fairing) and the firewall and repeat the sealing procedure whenever you install the bottom fuselage cover (belly fairing). This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to prevent fuel from flowing behind the firewall in the case of a fuel leak. This could result in an in-flight fire, which could cause loss of the airplane and crew.
