The National Transportation Safety Board on April 16, 2026 announced a two-day investigative hearing for UPS Flight 2976, scheduled May 19-20, 2026 in Washington, DC. The hearing covers the Board's ongoing investigation into the November 4, 2025 accident at Louisville Muhammad Ali International Airport (KSDF) involving a Boeing MD-11F operated by United Parcel Service. The accident, identified by NTSB as DCA26MA024, killed 14 people aboard the aircraft, one person on the ground who died of injuries some weeks after the event, and injured 23 others.
This article previews what an NTSB investigative hearing is, who the parties are, what evidence is presented, and how the hearing fits into the broader investigation timeline.
What an Investigative Hearing Is
An NTSB investigative hearing is a public proceeding in which the Board takes sworn testimony from witnesses and parties to the investigation. The hearing is part of the fact-finding phase. It is not a probable-cause determination — that finding is issued separately, in writing, after the entire investigative record is closed.
Hearings are reserved for accidents of significant scope or where complex issues benefit from public examination. They are convened at the discretion of the Board Chair. The decision to hold a hearing for UPS 2976 reflects the seriousness of the event and the breadth of the investigative questions in scope.
Who Are Parties to the Investigation
NTSB designates "parties" — organizations with the technical expertise and direct involvement to assist the investigation. For DCA26MA024, the typical party list for a Part 121 widebody freighter accident would include:
- United Parcel Service — the operator
- Boeing — the airframe manufacturer
- Pratt & Whitney — the engine manufacturer (PW4460 on the MD-11F)
- Federal Aviation Administration — the certifying authority
- Independent Pilots Association — the labor union representing UPS flight crews
- International Brotherhood of Teamsters — representing UPS ground operations
Parties have specific obligations: they provide technical assistance to the investigation, they may submit written briefs to the Board, and their representatives may question witnesses at the hearing under the Chair's direction. Parties do not vote on probable cause and do not issue findings — those are Board functions.
What Evidence Is Presented
The hearing format follows NTSB's standard pattern. Witnesses are called, sworn, and questioned by Board staff and by party representatives. The hearing record typically includes:
- Flight crew interviews and statements — interviews conducted during the investigation, transcribed and entered into the record
- CVR and FDR transcripts — the cockpit voice recorder and flight data recorder transcripts, partially redacted per 49 USC 1114(c) for CVR content not directly relevant to the investigation
- Maintenance records — for the involved airframe and engines
- ATC tapes and tower communications — radar, voice, and ground operations records
- Wreckage examination findings — structural, systems, and engine teardown reports
- Expert testimony — from engineering, human factors, and operations specialists
Witness lists and the full hearing agenda are typically posted to the NTSB Investigation Page in the days leading up to the hearing. As of this article's publication, the agenda for DCA26MA024 has been described publicly only as "to be released in the coming weeks" — meaning this week's editorial window is the natural pre-hearing scope.
What the Hearing Will Not Do
The hearing will not produce a probable-cause finding. That comes later — typically 12 to 24 months after the event, depending on complexity. The hearing assembles the evidentiary record. The Board's deliberation and probable-cause vote happen in a separate, later proceeding.
The hearing also will not issue safety recommendations. NTSB does issue urgent safety recommendations during active investigations when the evidence warrants, but those are released through standard recommendation channels, not at the hearing itself.
What Pilots and Operators Should Watch
For pilots and operators in the Part 121 cargo and the MD-11F community specifically, the hearing matters for several reasons:
- CVR/FDR public release. Once the docket is opened (typically near the hearing date), CVR transcripts and FDR data become public. This is the first opportunity for the broader pilot community to see the recorded sequence.
- Maintenance and operational program scrutiny. UPS's maintenance program, training program, and operational procedures will be examined in the hearing record. Findings about programmatic gaps, if any, foreshadow likely safety recommendations.
- MD-11F community implications. Few US operators still fly the MD-11F. Any findings specific to the airframe or its systems will affect those that do.
- Boeing and manufacturer findings. Engine, system, and structural findings will inform the manufacturer's own service-bulletin and field-action posture.
For the AeroCopilot reader who is not a Part 121 pilot, the hearing is a window into how a major aviation accident investigation actually works — the rigor, the public process, and the discipline of fact-finding before causation. Worth watching live or on replay through NTSB's video stream.
