A new ASTM International standard will be helpful in determining load data for small airplanes. ASTM’s general aviation aircraft committee (F44) developed the new standard, which will soon be published as F3498.
According to ASTM International member A.K.M. Haque, the new standard will be used by aircraft manufacturers to certify new designs; aircraft repair and modification organizations to certify changes to aircraft; and regulatory agencies that need to approve changes submitted by applicants.
“Fatigue load spectra generated using this practice can be used on small airplanes,” says Haque, senior engineer specialist, Textron Aviation. “It does not depend on the materials used to build the wing and/or empennage, the stabilizing surfaces on an aircraft’s tail.”
Haque notes that the standard defines overall fatigue load spectra for conventionally designed airplane wing and/or empennage. The standard can be used for airplanes that are powered by any type of clean energy.
To purchase standards, contact ASTM International customer relations (tel +1.877.909.ASTM; sales@astm.org).
All interested parties, especially those with knowledge of structural design and repair analysis abilities, are welcome to join the general aviation committee.
