Per AC 107-2A § 8.3.5.1, how can a remote pilot confirm that a small unmanned aircraft's declaration of compliance for Category 2 operations is currently valid?

Why: AC 107-2A § 8.3.5.1, p. 8-4, directs a remote pilot to check online at uasdoc.faa.gov to confirm the declaration of compliance is valid, and to visually inspect the aircraft to confirm the Category 2 label is affixed.

• A declaration of compliance can be rescinded after purchase under § 107.160(d); AC § 8.3.5.1 places an ongoing responsibility on the remote pilot to check validity, not a one-time assumption made at purchase.
• No phone-confirmation-number process exists; the AC directs pilots to the public online database plus a physical label check, not a Flight Standards District Office phone call.
