FORM UC-36 (REV. 09-2026)UCDP MANDATE: 2026-11-02
UADCHECKPre-submission inspection of UAD 3.6 packages

SYS9007

FATAL

Official message text · UCDP UAD 3.6 System Findings (2026-08-04)

Invalid Appraisal Report PDF File.

Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).

What triggers SYS9007

The file with a .pdf name is not actually a valid PDF (wrong file renamed, zero-byte file, or corrupted output).

    How to fix it

    Open the PDF from inside the ZIP and confirm it renders. If not, re-export the package; if the export is producing a bad PDF, that's a form-software support case.

    The free UADCheck inspection evaluates SYS9007 automatically — attach your package and see in seconds whether it fires.
