Implementation and Record Keeping
For major alterations performed in accordance with FAA field approval policy, the owner/operator operating under
Part 91 is responsible for ensuring that the ICA is made part of the applicable section 91.409 inspection program for
their aircraft. This is accomplished when a maintenance entry is made in the aircraft's maintenance record in
accordance with section 43.9. This entry records the major alteration and identifies the original ICA location (e.g.,
Block 8 of FAA Form 337, dated ______) along with a statement that the ICA is now part of the aircraft's
inspection/maintenance requirements.
