## Abstract

These special conditions amend Special Conditions No. 25-ANM- 84, applicable to Boeing Model 777 series airplanes. They revise the extended range operations with two-engine airplanes (referred to as "ETOPS") test requirements defined in the original special conditions. The revisions include changing the airplane demonstration test requirement from a required 1000 flight cycles to a demonstration of capability in ETOPS flight conditions, and allowing more than one airplane to be used for the airplane demonstration test. In addition, this revision adds post-test inspection requirements for both the engine demonstration test and the airplane demonstration test articles.
