[Form 337](https://help.airworthy.com/logbook-records-forms?hsLang=en#form-337) June 2, 2025 # Linking an unlinked 337 or ICA to an Aircraft Profile ## Users can attach their 337s and ICAs to Aircraft Profiles if they were not created from a profile already Sometimes, users may be using the 337 and ICA form tools on their own without creating them from [an aircraft profile](https://help.airworthinessdirectives.com/how-to-create-an-aircraft-profile?hsLang=en). We always recommend users drive all work from an aircraft profile, helping link workflows and organize information under the aircraft. To link ICAs and 337s that were unlinked to begin with, open your aircraft profile that you want to link them to first. Then, navigate down to the 337 or ICA section and click on the **'Action'** button then select the appropriate link option("Link Form 337" or "Link ICA"):   ![](https://help.airworthy.com/hs-fs/hubfs/image-png-Jun-02-2025-08-02-51-7385-PM.png?width=979&height=326&name=image-png-Jun-02-2025-08-02-51-7385-PM.png) ![](https://help.airworthy.com/hs-fs/hubfs/image-png-Jun-02-2025-08-03-30-6669-PM.png?width=994&height=222&name=image-png-Jun-02-2025-08-03-30-6669-PM.png) Clicking these will allow you to select the appropriate 337 or ICA and link them to that aircraft profile.  **\*NOTE: To link an ICA or a Form 337 -
