His opposition by voting "YES" on it is curious. It seems like the wrong order to proceed. Would it not be better to object to the provision before the vote when there could be some influence in the House rather than hoping the Senate won't agree and just pass it as-is.
Though in hindsight, his initial comment "This legislation restores our military\x92s focus on lethality" is a bit on the nose.
It's just baffling why the Army doesn't keep the ADS-B equipment on their helicopters operable, it'd be safer at any altitude when they're sharing airspace with civilians. I can only imagine someone thinking, "well we can't stop doing training flights when the equipment isn't working" (and Homendy glaring at them "then get it fixed"). 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

weird that they don’t even mention the Blackhawk PF’s straying from altitude constraints, the IP repeatedly tells her about her deviations multiple times as per the transcript, baro altitude limitations or not they were both aware she wasn’t meeting the limits of the corridor (that the margins are so fine in that airspace is absurd of course)
https://www.ntsb.gov/investigations/...CA25MA108.aspx
31. Due to additive allowable tolerances of the helicopter’s pitot-static/altimeter system, it is likely that the crew of PAT25 observed a barometric altimeter altitude about 100 ft lower than the helicopter’s true altitude, resulting in the crew erroneously believing that they were under the published maximum altitude for Route 4.
.
27. The PAT25 instructor pilot did not positively identify flight 5342 at the time of the initial traffic advisory despite his statement that he had the traffic in sight and his request for visual separation.

As some won't follow the link and read all of the findings, I think it's only fair to the IP to quote the next finding as well, which speaks to concerns over the inherent (un)safety of visual separation at night in dynamic traffic environments:
28. With several other targets located directly in front of the helicopter represented by points of light with no other features by which to identify aircraft type, and without additional position information from the controller, the instructor pilot likely identified the wrong target. The question was why the NTSB chose the right seat of the helicopter, and that was because the instructor assumed responsibility for the visual separation. There is no cockpit communication about the identification, so the PF wasn't involved in that. One problem the helicopter had was that the CRJ was flying a turn. Flying straight, you know you're going to collide with something (even if it is just a dot of light) if it doesn't move visually. The CRJ's lights were moving left, so that would've looked like it was safely passing the helicopter by. The crew needed the situational awareness that the CRJ was going to turn towards them as it lined up for runway 33, but they didn't have it. ATC did, but didn't share, for reasons also addressed in the findings. 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.

The Helicopter Pilot flying the helicopter flew 56 hours the previous year prior, a little more than 4.5 hours per month! Only 4.4 hours in the previous 60 days! And She was on a checkride! Any military pilot will attest to the fact that when your due a checkride you try to get some practice flying prior to the checkride. I guess all the additional duties precluded that .Tough to stay proficient flying so little…..
A pilot who flew with the accident pilot stated that she practiced basic flight maneuvers and NVG tasks in preparation for her upcoming evaluation flight. He recalled that the pilot seemed “rusty” due to a lack of recent flying but that, otherwise, nothing stood out about her performance.
.
The PF actually had more hours on the "accident helicopter make and model" than the instructor pilot, and people who flew with her in 2023 and 2024 thought she was flying well enough. Subjects

We don't know of any gestures, if any pilot pointed at lights, but there is nothing in the CVR transcript that indicates the PF was aware of the traffic, or that the PIC pointed the traffic out to her; the PF certainly did not factor in the decision to request visual separation. So when the PIC transmitted,
20:46:07.9
RDO-1
PAT two five has the traffic in sight request visual separation
.
what would you have the PF do? Ask the instructor where it is? Or trust the instructor, and concentrate on flying?
or did the PF know that neither of them could identify the traffic, but accepted it as normal? Subjects

the PF had also shown their handling skills were not to standard earlier in the check ride (I’ve seen it mentioned their abandoning a manoeuvre earlier would’ve been a fail normally) hence monitoring their trainees parameters would’ve been even more taxing for the instructor
I don’t know how anyone can pretend these things didn’t at least play a part in the Swiss cheese.
if the PF had been as equally capable as the instructor and performing their scan (the CGI reenactment shows that much of the CRJ’s flatboats occurred within the PF’s side of the scan) would the outcome have been different? Possibly. the conduct of that flight was the final hole in the Swiss cheese arguably What I do see is that when the instructor is flying, he's having some altitude excursions as well. There's also a visual separation while the instructor is flying, and it plays out like this:
20:00:11.0
APR-P
PAT two five if you hear Potomac acknowledge with an IDENT. traffic at your nine to ten o'clock in two miles eastbound one thousand eight hundred indicated its a helicopter.
.
INT-2 [trainee] do you see him? INT-1 [instructor] nope. INT-2 do you see him? INT-1 no. nine to ten o'clock. *. 20:00:22.7 RDO-2 * * traffic INT-1 yeah. I got it. tally. coming left. INT-1 alright you want me to keep chasing this number one needle or- INT-2 yeah. just avoid traffic at this point. INT-1 yup. I got the traffic out the right door and only then does she call 'traffic in sight maintaining visual separation'. For the CRJ, the instructor calls 'traffic in sight' without ascertaining that the PF sees it. When the tower cautions them again, the CRJ still hasn't turned, so while it's visible, it doesn't appear a threat. I think both pilots expect the CRJ to be to their right, because that's where the bridge is when ATC tells them where the CRJ is initially, and because the instructor thinks that ATC wants them to move left. They don't understand that the CRJ is on their left and will be turning onto the runway heading. I imagine, based on that, that the PF believed the instructor has the CRJ in sight on his side. If she did see the CRJ, it would've been well above and on a diverging course, except for the final 6 seconds or so; it wouldn't have appeared to be a threat. With his radio call, the instructor put himself in the position of being responsible for avoiding AA5342, but he didn't actually know where it was (maybe he thought he did). There are a lot of factors contributing to that, but that's the big hole here for me. Last edited by Musician; 19th February 2026 at 18:47 . Subjects

Thank you!
Clearly, he hadn't. I'm impressed with the NTSB's reporting on this aspect: the difficulties of using NVG to identify and visually separate from other aircraft are very well described in the narrative, and the photographs through NVG from representative vantage points illustrate them superbly for the uninitiated.
