scope:

This document contains rotorcraft airworthiness qualification requirements for propulsion systems. The issuance of a Contractor Flight Release (CFR) to initiate aircraft ground and flight testing is contingent upon successful completion of the analysis and component qualification requirements as contained in ADS-50-PRF. The issuance of an Airworthiness Release (AWR), from a propulsion point of view, is contingent upon successful completion of the analysis, surveys, and demonstrations listed in paragraph 1.2 above. The remaining paragraphs below, are to be used as guidance in defining the required surveys and demonstrations above. The surveys and demonstrations herein are normally divided into two segments; an initial series of propulsion interface surveys and subsequent propulsion demonstrations. In effect, propulsion surveys are considered a subset of the more formal propulsion demonstrations leading to airworthiness qualification. The original ADS-1 addressed only propulsion interface surveys. This revision has been expanded to include all propulsion demonstrations. This ADS has also been updated to reflect current technology and lessons learned from recent flight test programs.
