Aeroporto Municipal Danilson Cirino Aires da Silva CIZ / SWKO

Coari (CIZ/SWKO) is self-administered by the city government via its Departamento Aeroportuário de Coari — confirmed by Wikipedia (administration listed as municipal) and independently by a Gazeta do Povo profile naming the department and its director, Eufrázio Azevedo Filho (that profile dates to 10 Feb 2009, not 2026 — see security entry). No third-party ramp/ground-handling concessionaire (Infraero, CCR, Vinci, Aena, Socicam, etc.) was found for this field, so basic apron, marshalling and turnaround support at this small single-carrier strip is presumed to rest with this municipal department; not documented at the individual-service level.

Azul is the sole scheduled carrier at CIZ — confirmed via flightconnections.com, which shows Azul operating CIZ-Manaus (MAO) as the only currently active route, roughly 18 flights/month (about 7x/week), correcting an earlier draft's unsourced '~4x/week' figure. No third-party ground-handling agent for CIZ was found in Azul's own materials, handling-agent listings, or trade press; the pattern is consistent with Azul self-handling its own turnarounds (check-in, ramp, baggage) at small Amazon interior stations, noted here as self-handled, Azul, but this specific arrangement is not directly confirmed for Coari.

JET A-1 into-plane fuel supplier at Coari/SWKO. Confirmed as the fuel contact on the DECEA AISWEB aerodrome information card for SWKO — the listed phone (••• matches this record exactly (re-checked live on aisweb.decea.mil.br). Santinaviation.com (the Santin Aviation / VOA portal) does offer per-aerodrome Brazilian jet-fuel price lookups, consistent with the kind of independent price-tracker citation used in the original research, but the specific SWKO price-table entry (~R$15.78/L, effective 7/2026) could not be independently reloaded to re-confirm on — treat that exact figure as unconfirmed pending re-check; the underlying supplier claim itself is solid via AISWEB. Pioneiro Combustíveis is reported to be an Amazonas-based into-plane/refuelling company serving 30+ airports and airstrips across Amazonas, Acre, Roraima and Pará, including Manaus/Eduardo Gomes, Santarém, Itaituba, Carauari and Flores; the company's own website could not be reached on to verify its 1991 founding date directly, but this detail is peripheral to the confirmed SWKO fuel-supplier claim.

Nominally the responsibility of the municipal Departamento Aeroportuário de Coari as airfield operator. A Gazeta do Povo article, 'Diretor do aeroporto de Coari admite não fiscalizar voos', published 10 Feb 2009 (corrected here — an earlier draft mis-dated this as an 'August 2026' report), quotes the then director, Eufrázio Azevedo Filho, admitting no aircraft/flight inspection was performed at the field, and reports the airport had previously been interdicted in 2006 over perimeter-security failures (farmers/livestock crossing the runway during takeoffs). No dedicated aviation-security firm or regulated-agent cargo-screening operation was identified. This is a 17-year-old account with no more recent report located confirming whether conditions have since improved; flagged unconfirmed/historically deficient rather than omitted, per the zero-is-a-red-flag rule — treat as dated evidence, not current status.
