Background
Since its release on April 21, 1971, AC 20-73 continues to be
followed as a means of compliance for inflight icing regulations. The
objective of this revision is to provide a uniform and modern means of
compliance with regulations for aircraft and engine ice protection
requirements. This revision of AC 20-73 is extensive. It addresses
common ice protection means of compliance for airplanes, rotorcrafts,
and engines, with references to other applicable advisory circulars
that address specific types of aircraft, engines, or regulations. An
effort has been made in this revision to make the information congruent
with compliance means provided in other existing guidance material and
policies. Note however that there are instances where current
technology is considered sufficient to justify changes, and means of
compliance not previously addressed in guidance and policy material are
discussed in this proposed document.
