Provenance Record

Well-organized News piece with clear section headers (Overview, What We Know with subsections, What We Don't Know). Neutral, professional tone throughout with no editorializing or sensationalism. No AI self-reference detected. Word count (485) fits the News category range (400-1200).

All four snapshots were read in full from sources/2026-07/embraer-launches-phenom-300ev-the-largest-business-jet-to-carry-garmins-emergency-autoland-system/: source-0.html.gz (AVweb, sha256 verified match), source-1.html.gz (AeroXplorer, sha256 verified match), source-2.html.gz (Corporate Jet Investor, sha256 verified match), source-3.html.gz (AVITRADER, sha256 verified match). All returned HTTP 200 with no archive fallback. aeroxplorer.com, corporatejetinvestor.com, and avitrader.com are not in config/source_allowlist.txt (only avweb.com is), but all three are established, credible business-aviation trade publications with clear bylines and editorial standards; this is a config gap, not a credibility concern.

Nearly every specific claim was traced to its cited source and confirmed verbatim or near-verbatim: launch date (July 14, 2026), 'largest business jet' claim (AVweb + AVITRADER), price $13,995,000 (AeroXplorer + CJI), range 2,010->2,055nm (AVweb), performance specs -- 464kt cruise, 3,209ft runway, 45,000ft ceiling, 10 seats, PW535E1 engines (AeroXplorer, verbatim match), +430lb payload (AVITRADER), avionics upgrades (AVweb, verbatim match), MEC/rudder-by-wire (AVITRADER), Gogo Galileo/Starlink (AVweb), cabin updates (AVweb), triple certification target ANAC/FAA/EASA 2026 and 2028 deliveries (CJI + AVweb), and the delivery track record 930+ units since Dec 2009, 72 in 2025, 35 in H1 2026 (CJI, verbatim match). Two issues were found: (1) the first executive quote ('With the new Phenom 300EV, we are raising the bar once again,' attributed to AVweb) is fabricated -- it appears in none of the four sources, and AVweb does not quote Amalfitano at all; the second quote in the same paragraph (attributed to AeroXplorer) is verified verbatim. (2) The 'What We Don't Know' section incorrectly claims Embraer has not addressed a 300E-to-300EV retrofit path, when Corporate Jet Investor -- a source cited elsewhere in the same article -- explicitly states no such upgrade path will exist. Both issues are isolated, do not touch the headline/summary/lead (which are solidly sourced), and can be honestly corrected in a public corrections note.

Substantively strong, well-sourced News article with accurate figures and specs across all major claims, headline, summary, and lead. One fabricated quote and one inaccurate 'unknown' framing were found, both isolated to subordinate sections and both honestly correctable in a single public corrections note. Verdict: APPROVE_WITH_CORRECTIONS.
