CENTRO OESTE MANUTENCAO DE AERONAVES LTDA

Showing 8 of 112 snapshots (the first plus the most recent); the chart and the Δ consider all of them.

Peaked at 2 aircraft (Jul/17, Feb/18, Mar/18, Apr/18, Feb/19); the latest snapshot shows 0. The endpoint delta alone would not show the peak.

2 aircraft came and went between the endpoints: they only show up because we look at every snapshot, not just the first and the last.

Comparison across the RAB snapshots we hold. Between two snapshots there is no reading: the change may have happened at any point in the window, and the aircraft may have passed through other operators along the way.

The 80 snapshots before Sep/24 come from ANAC's monthly file without the engine column: reserved marks are under-detected in that stretch, and at the Sep/24 seam an aircraft that starts showing as reserved may just be detection kicking in, not a change in the RAB. Every attribution starts from the CNPJ reported by ANAC. From May/18 to Dec/21 ANAC masked every document: in those snapshots the CNPJ comes from name continuity on the same registration and, where that is not enough, from the company name when it resolves to a single CNPJ in our records (tax registry and current registration). Ambiguous names or vanished companies are left out.
