16. Revision
To revise this ICA, a letter must be submitted to the local FSDO with a copy of the revised FAA
Form 337, and revised ICA. The FAA inspector accepts the change by signing Block 3 and including
the following statement:
"The attached revised/new Instructions for Continued Airworthiness (date ______) for the above
aircraft or component major alteration have been accepted by the FAA, superseding the Instructions
for Continued Airworthiness (date ______)."
17. Assistance
Flight Standards Inspectors have the resources to respond to questions regarding the ICA.
18. 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.
