Editing Foreign object damage (section)

==To jet engines==
[[Jet engine]]s can suffer major damage from even small objects being sucked into the engine. In the [[United States]], the [[Federal Aviation Administration]] (FAA) requires that all engine types pass a test which includes firing a fresh chicken (dead, but not frozen) into a running jet engine from a [[Chicken gun|small cannon]]. The engine does not have to remain functional after the test, but it must not cause significant damage to the rest of the aircraft. Thus, if the [[bird strike]] causes it to "throw a blade" (break apart in a way where parts fly off at high speed), doing so must not cause loss of the aircraft.<ref>{{Cite web|url=http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/1ab39b4ed563b08985256a35006d56af/342f360c7f8e146a86256a84005b1f57/$FILE/ac33.76-1.pdf|title=FAA Advisory Circular|access-date=2008-03-27|archive-date=2017-04-09|archive-url=https://web.archive.org/web/20170409201233/http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/1ab39b4ed563b08985256a35006d56af/342f360c7f8e146a86256a84005b1f57/$FILE/ac33.76-1.pdf|url-status=dead}}</ref>
