A law enforcement officer asks a remote pilot to submit to a blood alcohol test at the flight site. The pilot refuses. What is the consequence under 14 CFR Part 107?

Why →Under 14 CFR § 107.59, a refusal to submit to a blood alcohol test when requested by a law enforcement officer is grounds for suspension or revocation of the remote pilot certificate with a small UAS rating. The regulation provides no exception based on the pilot's belief that they have not consumed alcohol. Refusal itself carries the consequence.

The trap →Being confident you are sober does not create a right to refuse under § 107.59. The refusal, not just a positive test result, is independently grounds for certificate action.

Field note →This parallels the manned aviation rule under 14 CFR § 61.16. The FAA treats refusal as seriously as a violation because refusal defeats the enforcement mechanism for the alcohol prohibition entirely.
