The helicopter should never have been allowed to be that close to landing traffic,
In any case the procedure us currently withdrawn until end of March and I sincerely doubt they will re-install it before the final report is out. .. A couple of new info points the NTSB clarified : Both aircraft were on VHF , so we can drop this UHF discussion , the Blackhawk had ADS-B equipped but was not transmitting , it was check ride with NVG, and they most probably all had them on .and there was a last second evasive action attempt by the CRJ crew, which go a TA previously . On the TWR, the CAs are displayed in the BRITE even with audio on .. For the rest we have to wait until the next NTSB briefing Subjects

absolutely . the altimeter talk is just a distraction or at best contributing factor, Not the cause .. which brings us back to the safety assessment of the procedure , which the NTSB did not mention at all,, but I am sure , or at least I hope they will go into in their final report.
I sincerely hope the NTSB can avoid being distracted by the distractions of altimetry and the missing ATC words on the Blackhawk CVR. Upthread, Luca Lion calculated the 3 degree PAPI approach path as crossing the eastern riverbank at 270ft. If that's correct, then the CRJ's 313ft radar height 2 seconds before collision puts it at least 43ft above the approach path, so the Blackhawk's radio height deviation of 78ft would have contributed only about 35ft to the erosion of any intended "procedural separation" (*) between the aircraft. Or, to put it another way, the same outcome would have resulted if the Blackhawk had been at 235ft radio and the CRJ on the glide. Height keeping of plus or minus 35ft can only be achieved by instrument flying, which is obviously not compatible with visual separation (or indeed VFR) so cannot be reasonably cited as part of a safety case for the procedure. And of course a landing aircraft could easily be below the glide. Altimetry and height keeping are not the cause of this accident. Missing the word "circling" wouldn't have influenced the helo crew getting visual with the CRJ at the time of the trasnmission. At best, it would have given them an extra nudge that "runway 33" (which was audible) meant the CRJ would be taking an easterly flight path. Missing "pass behind" with only a few seconds to collision was irrelevant if, as seems likely, the helo crew did not see the CRJ at that point. (*) The quotes around "procedural separation" are intended to convey a tone of disgust and sarcasm. Last edited by Easy Street; 15th February 2025 at 10:47 . Subjects

After having completed three days of its formal proceedings - which I'll predict will long be remembered for the Board Chair ordering witnesses
from FAA
to turn off their cellular devices and to relocate because one had been seen elbowing another during the latter's testimony - the Board may be about to enter a new kind of Washington ball game.
Twelve billion dollars here, eighteen billion dollars additional there, pretty soon you're talking real money (with apologies to anyone who recalls the originator, Illinois Senator Everett McKinley Dirksen). With all that federal largesse provided by the American taxpayer destined to be spent on the so-called "new ATC system", I have a question. Isn't it necessary to know what conclusions the Board reaches in this investigatory process before committing to - and I'm going to use my own phrase - the "new National Airspace Architecture"? The United States needs a new FAA organization, on two fronts at least. One, separate the ANSP from the regulator (as probably hundreds of real-life aviation industry worthies have long advocated). Second, a new organizational structure, ethos, culture, set of career pathways, and everything else that is not fit for purpose for the immient and dramatic changes dead-ahead (such as automation, Advanced Air Mobility, environmental pressures, and oh yeah, increased traffic correlated with increased demands from the traveling public for the precise kind of bag of peanuts to which they believe they're entitled). Is it not the case that FAA has failed in its fundamental mission, because under no ConOps should it have been possible for this accident to take place? (Of course, there will never be a guarantee against one or more persons conducting relevant activities with gross negligence - but if that harsh judgment is levied against the Black Hawk, nonetheless the system should have provided stronger procedural separation.) And all this is before decisions are made about what technologies to build into the new Nat'l Airspace Arch., what vendors, what geographic arrangement, and what connectivity the entire system will have with ATM in Europe and globally (and European ATM especially is moving rapidly into the future). But the Board final report is what, 12 months away? 18 months perhaps? And as the new National Airspace Architecture is supposed to be undergoing definition and development, what assurance is there that the upcoming 42nd Triennial Assembly of ICAO in Montreal will not take action which will seriously impact the U.S. process? Or set ICAO on further intitiatives which would constrain U.S. plans, and not necessarily for the better? Recall that the United States has not had a designated Permanent Representative to ICAO since Capt. Sully abruptly resigned (July 2022), and while the career Foreign Service officials heading up the U.S. Mission undoubtedly are fine and excellent public servants, they are not ( afaik ) aviation industry professionals. None of this is to say that the NTSB should speed up its process and deliberations. But at the same time, if during this Assembly the Secretary of Transportation shows up - as happened during the previous Assembly - to speak on behalf of the United States, I hope the Secretary has very, very good speechwriters because it will be hard to say anything meaningful when the state of affairs is in such disarray. Edit: On July 17 the White House nominated former Delta Airlines Capt. and U.S. Navy aviator Jeffrey Anderson to the position of Permanent Representative to ICAO with the rank of Ambassador. Timing of Senate confirmation hearing is presently unknown. Last edited by WillowRun 6-3; 3rd August 2025 at 22:34 . Subjects

Ordinarily I have no objection to lawyer bashing (and I've been known (in non-anonymous mode) to tell one or more good lawyer jokes). Before stating why I object to the aspersion you've cast on legal types in the context of the DCA mid-air collision and the litigation arising from it, I'll suggest that probably most all forum posters (and readers), if not literally all, have heard either an ex-husband or ex-wife relate their unrequited frustration and anger at how the other spouse "got everything", "ripped me off", "took me to the cleaners" and so on. And then someone else will say, "yeah, and the lawyers are the only ones who profit in a divorce." The contradiction is rarely called out, but it is no less a contradiction. But as to this case. The passenger manifest of the PSA flight isn't necessary to make this point, but I'm sure the estimable Mr. Clifford would consume hours of argument and pages of supporting documents making it clear that 64 lives were cut short, and many were people in the prime of their adult lives - not that one life should be worth more than any other life in compensation in court proceedings, but taking for example the relatively early career attorneys who perished in the accident, their earnings potential over the course of their careers is less speculative than, say, projections about one of the youthful skaters (although I'm pretty sure there are standards which have been worked out in the mine run of personal injury and wrongful death cases). My point is, this case will yield quite significant damage awards in the end. Yes, I realize that issues of immunity of federal agencies will have to be surmounted; having posted a lot about theses issues I realize they exist. Yet the citations of FAA orders, procedures, and rules in the Complaint does suggest that plaintiffs are ready to overcome the immunity argument. And I'm leaving for another day and place the consideration, how do you think it would affect the FAA in the long run to argue that "na na you can't get me" because of "legal technicalities" when it is pretty predictable at this point that NTSB in its final report will be, shall we say, either unkind or unsparing to FAA, or both, in assessing causes and effects. So the case is likely, if not certain, to pay out big. The lawyers will get - unless legal counsel are using very different formulas than are typical in cases of this type - about one-third. How is it then that only the lawyers do well? The argument is not about whether big-ticket damage awards can replace a lost loved one. The argument is about whether only the lawyers do well. "Grief" begins with the same four letters as "Grievance" and the crash victims' families certainly are individuals aggrieved by the negligence of some or all of the defendants. Maybe we can split semantic fibers over whether having their grievance abated by significant financial compensation is within the meaning of "doing well" - but under the facts of this case and their tragic losses, I think they will be at least "doing better". And so not only the lawyers. This all having been said, apologies accepted, naturally. WR 6-3 Subjects

Looks basically correct, though I would add some points.
- The bill mandates a "risk assessment", but does not explain what that entails, or how the person making that assessment should be qualifed. A simple check box on the waiver form, "I assessed the risk to civil aviation", would presumably suffice. - The civil aviation authorities (DOT, FAA, airlines) have no input on these assessments. This is why Homendy calls it a "whitewash", because it sounds like someone cares about risk, but there's no actual assurance the risk would be managed. - Because these and other important provisions are so poorly defined, Homendy called the section badly written, and she's right. You need to know what the bill is talking about, or the ambiguity leads to court cases. - we have seen a legislative effort to mandate ADS-B IN, which may be ongoing behind the scenes, and possibly scheduled to a push with the release of the final report. However, ADS-B IN is useless (in this context) if the military doesn't send ADS-B. I think that explains Homendy's level of anger. I believe, without this provision, the Army needs to fix their ADS-B gear, and go to the FAA if they need a waiver for those top secret missions. Subjects

NTSB meeting January 27 - probable cause determination
According to reporting published today by The Air Current - one of its periodic articles reporting on air safety which are not paywalled - the NTSB will meet on January 27. The meeting will include revealing and voting on the probable cause determination produced by its investigation into the DCA midair collision 29 January 2025.
The reporting indicates that the Board's final report is expected within two weeks. Various safety recommendations also are anticipated to be on the agenda for the NTSB's January 27 meeting. Of particular interest, among many other factors involved in this horrifically senseless accident (my characterization, not found in TAC reporting as such), is whether the NTSB's meeting which will mark the end of its official investigatory process will touch upon the controversial section of the NDAA, Section 373 (subject of previous posts at the time of passage, upthread).

Legislation in U.S. House of Reps. pending .....
Waiting to see what becomes of the controversial Section 373 in the recent NDAA.
_________________________ Joint Statement of House Transportation and Infrastructure Committee and House Armed Services Committee Bipartisan Leaders on NTSB\x92s Recommendations to Address DCA Crash For Immediate Release: February 06, 2026 [Committee contacts omitted] Washington, DC \x96 The bipartisan leaders of the House Transportation and Infrastructure Committee and the House Armed Services Committee today issued a joint statement regarding the National Transportation Safety Board\x92s (NTSB) recently approved recommendations to address the January 29, 2025, midair collision at Ronald Reagan Washington National Airport (DCA). Joint statement from House Transportation and Infrastructure Committee Chairman Sam Graves (R-MO), House Transportation and Infrastructure Committee Ranking Member Rick Larsen (D-WA), House Armed Services Committee Chairman Mike Rogers (R-AL), and House Armed Services Committee Ranking Member Adam Smith (D-WA): \x93Now that we have received the approved recommendations and probable cause from the NTSB on the tragic DCA midair collision that claimed 67 lives, and with the NTSB\x92s final report expected in a matter of days, we are working on a comprehensive legislative solution to address what we\x92ve learned. It is our firm belief that meaningful improvements to the safety of our airspace require the full and fair consideration of all of the NTSB\x92s recommendations. We are continuing to evaluate the information and analysis gathered and put forward by the NTSB, and we will work together expeditiously on legislation to ensure a crash like this can never happen again.\x94 Subjects

https://www.politico.com/live-update...-bill-00764270
But Transportation Chair Sam Graves (R-Mo.) has objected to the bill, saying he wants big changes to it.
In a series of recent interviews, Graves has cited concerns over impacts to general aviation, the small-scale flights that range from recreational trips on single-engine planes to crop dusting.
On Tuesday, the top Democrat on the House transportation panel, Rep. Rick Larsen of Washington, said in an interview he was mulling two options: either adjusting the ROTOR Act or crafting new legislation after the National Transportation Safety Board last week issued 50 recommendations related to the catastrophe, which killed 67 people.
.
The journalists asked Homendy about it on the day of the board meeting, and she diplomatically said she'd been busy with the DCA midair documents since the board meeting and final report were coming up, but she also reiterated she wants ADS-B IN on every aircraft, so... The NTSB has the enviable role of being able to champion safety absent any other consideration. The FAA and politics in general need to balance that with economic, business and other interests, so the outcomes are pretty much guaranteed to be compromises falling short of what we would want.

Page 242 ff. in the final report pretty much exonorates the PF in the helicopter, in my opinion.
.
Altimeter testing showed that the 100-ft pressure altitude discrepancy seen in the FDR data for the accident flight was observed on three other UH-60L helicopters operated by the 12th Aviation Battalion. These altimeter testing results also showed that the pressure altitude data recorded by the helicopters\x92 FDRs, when corrected for local conditions, was representative of what was indicated on the right side altimeter. Therefore, the FDR pressure altitude data for the accident helicopter, when corrected for local conditions, was likely representative of what was indicated on the IP\x92s barometric altimeter during the accident flight.
[...]. The NTSB concludes that, due to additive allowable tolerances of the helicopter\x92s pitot-static/altimeter system, it is likely that the crew of PAT25 observed a barometric altimeter altitude about 100 ft lower than the helicopter\x92s true altitude, resulting in the crew erroneously believing that they were under the published maximum altitude for Route 4. For the northern segment of Route 4, which included the area of the collision, of the 523 flights analyzed, 260 flights (49%) were identified as exceeding route altitude limitations at some point during the flight. Had the error tolerances of barometric altimeters been considered during design of the helicopter route maximum altitudes, the incompatibility of a 200-ft ceiling and barometric altimeter errors may have been identified.

For Chiefttp:
The question of currency, proficiency, and recency fairly leap off of the page, yes. I am not sure how much low level, over water, at night flying that you have done, but I have done quite a bit of that. If you are flying in such a regime, and there is a substantial mismatch between your radalt, and your baralt, and you have a hard altitude limit, you don't ignore your radalt. Subjects

Legislation
From House Transportation and Infrastructure Committee website 19 February 2026 Washington, DC \x96 The comprehensive legislative response to the various aviation safety issues raised by the tragic 2025 midair collision between American Airlines Flight 5342 and a UH-60 Army Black Hawk helicopter at Ronald Reagan Washington National Airport (DCA) was released today by the bipartisan leaders of the House Transportation and Infrastructure Committee and the House Armed Services Committee. The Airspace Location and Enhanced Risk Transparency (ALERT) Act of 2026 addresses all 50 safety related recommendations issued by the National Transportation Safety Board (NTSB), which concluded its thorough investigation and issued its final report on February 17, 2026. The ALERT Act considers all of the NTSB\x92s findings of probable cause that contributed to the accident and responds to each of the NTSB\x92s 50 safety recommendations to provide a thorough and holistic legislative solution to improve U.S. aviation safety. Critical safety issues the bill addresses include: Establishing requirements for equipping collision mitigation, avoidance, and alerting technologies and systems for civil fixed-wing and rotorcraft; Improving helicopter route design, guidance, and separation; Preventing loss of separation (near-miss) incidents; Addressing deficiencies in the FAA\x92s safety culture; Enhancing air traffic control training and procedures, particularly during high traffic; Strengthening the safety of the DCA airspace \x96 one of the nation\x92s busiest and most congested airspaces; Repealing section 373(a) of the last National Defense Authorization Act; and more. The ALERT Act is led by Transportation and Infrastructure Committee Chairman Sam Graves (R-MO), Transportation and Infrastructure Committee Ranking Member Rick Larsen (D-WA), Armed Services Committee Chairman Mike Rogers (R-AL), and Armed Services Committee Ranking Member Adam Smith (D-WA).
