[NTSB ERA27LA018](https://openairdocs.org/ntsb/ERA27LA018), Oct 10, 2026: Piper J3C-65 (N6340H), Limington, ME, investigation ongoing From 1962 to 1981 and from 2008 on, NTSB codes phases with the CICTT phases; from 1982 to 2007 with its older phase codes, counted under the CICTT main phase each maps to. Each case counts once, on its first aircraft: by its defining event's phase from 2008, its first event's before 1982, and its first occurrence's from 1982 to 2007. Compare years within an era: a first occurrence (1982 to 2007) is often in flight, before the landing, so landings count lower then. Findings: https://openairdocs.org/ntsb-findings.md.
