Background
This AC is on the subject of vibration tests and surveys, and was
identified as one where differences existed between the Joint Aviation
Requirements--Engines, and part 33 of the Federal Aviation Regulations
(FAR's). A study group composed of representatives of the Federal
Aviation Administration, the Joint Aviation Authorities, Transport
Canada and industry worked to produce a set of improved and harmonized
requirements that was subsequently incorporated into part 33 of the
FAR.

on the draft AC during the proposal and development phases. Notice was
published in the Federal Register on April 18, 1995 (60 FR 19442), to
announce the availability of, and comment to the draft AC.
This advisory circular, published under the authority granted to

provides guidance for these new requirements that were published in the
Federal Register on June 4, 1996 (61 FR 28430).
