Pentagon lost contact with Army helo that caused DC jet diversions

From non-paywalled content published today by The Air Current (quoted without any change):

U.S. Army Brigadier General Matthew Braman has rotated out of his role as Director of Army Aviation, leaving the branch\x92s central aviation office without clear leadership in the wake of January\x92s fatal midair collision between an Army Black Hawk helicopter and a PSA Airlines CRJ700 near Washington, D.C.\x92s Reagan National Airport (DCA).

An Army official told The Air Current that the move was made as a part of the Department of Defense\x92s broader effort to streamline its general officer workforce. Going forward, the role will be filled by a lower ranking Army Colonel (O-6), the official said, though the Army declined to comment on who is currently serving in Braman\x92s former role or who is expected to fill it.

Army personnel \x97 and others involved in the DCA investigation \x97 are due to appear starting on July 30 at the U.S. National Transportation Safety Board\x92s three-day hearing on the crash to submit sworn testimony and answer investigators\x92 questions. Braman is expected to testify during the hearing, TAC has learned.

Something smells wrong about some of this.
(I need to see a bit more of the documentation on the difference between the hard altitude (200') that I was under the impression was on that route, as opposed to the "recommended altitude" statement made there...maybe it will make more sense to me then).
As to altimeter errors.
The UH-60L has a radalt.
Are you trying to tell me that the alleged acceptable error for a rad alt is 80'-130'?
I think not.
I doubt that the rules have changed that much since I was last flying a Blackhawk. (yes, it has been a while).
Will do a bit more reading, thanks.

They were flying over the river, not the built up areas. Not sure how much time you have flying in a Blackhawk, but if you are over the water at night at 200' your radalt is giving you better indications of how far you are above water than your bar alt. If the two disagree, which one do you think you'll be using?
(Same is true in the Seahawk).

As to your point on the cause of the accident, yes, they were not aware of the traffic coming into 33 (for reasons beaten to death already).

I'm going to offer a contributing cause that I think merits consideration: there was mention made early on of there being 1, not 2, tower controllers on duty at the time when apparently 2 is the normal number.
Had there been two, the helicopter might have been handled differently, but we'll never know.


My recollection from the CW3 Roth (former 12th AB pilot) interview was he said the opposite; i.e., due to the frequent bridges/islands in the river, PAT25 would have been flying referenced to baro for route 1 and 4 altitude limits.

I have flown that route a handful of times during my time in the Marine Corps (admittedly it's been more than 20 years ago). I recall being asked to do a 360 turn over the Wilson Bridge for spacing (we were northbound) for traffic landing on 33.

In regards to your other comment about them not seeing the CRJ, I have believed from the time that the radio traffic was public that the controller was not specific enough when he asked PAT 25 "do you have the CRJ in sight?" Something along the lines of "PAT 25, CRJ on final for RWY 33 is at your 10 o'clock less than a mile, pass behind that traffic" should have drawn the helo crews eyes to the left to hopefully see the traffic. Even better would have been to have the helo do a left 360 over Hains Point.

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.

My question exactly. Where is the radar altimeter in this discussion. I also can\x92t believe that when flying a helo at night over water cross checking the radar altimeter with the baro altimeter is not just good practice but required!

DOT inspector launches probe into FAA\x92s Washington DC airspace management

The US Department of Transportation\x92s top inspector has launched an investigation into the Federal Aviation Administration\x92s management of airspace near Washington, DC.

The investigation will focus on the agency\x92s design of the airspace and its process of granting military exemptions to a requirement that aircraft use Automatic Dependent Surveillance-Broadcast (ADS-B) systems.

The review, disclosed by the DOT\x92s Office of Inspector General on 8 August, comes amid scrutiny over the FAA\x92s operations \x96 a response to the 29 January midair collision involving a US Army Sikorsky UH-60L Black Hawk helicopter and a PSA Airlines MHIRJ CRJ700 regional jet.

The helicopter had not been transmitting ASB-B \x93Out\x94 information when, flying higher than permitted, it collided with the CRJ700, which was moments from landing at Ronald Reagan Washington National airport, the National Transportation Safety Board has said.

Both aircraft plummeted into the Potomac River, killing all 65 people on the regional jet and all three on the Black Hawk. The Black Hawk had been operating a pilot training flight.


\x93We are initiating this audit to review FAA\x92s oversight of existing safety gaps in the management of DCA\x92s airspace, including the exemption process for ADS-B Out,\x94 says the DOT inspector\x92s office. \x93Our audit objectives are to assess FAA\x92s oversight and management of the airspace surrounding DCA, and policies and procedures to oversee ADS-B Out exemptions.\x94

The office intends to begin the audit this month.

The investigation comes at the request of two senators who asked the inspector general \x93to review a wide-ranging set of safety issues surrounding the accident\x94, the DOT office adds.

The FAA has since 2020 required aircraft have and use ADS-B Out, a system that transmits an aircraft\x92s position and other information about is flight to air traffic controllers. Aircraft equipped with ADS-B \x93In\x94 \x96 which the FAA does not mandate \x96 also receive the position reports. The ADS-B system is intended to give controllers and pilots more information about air traffic, helping prevent collisions.

Under a compromise with military and government aircraft operators, the FAA permits government aircraft operating \x93sensitive\x94 missions to be exempt from the ADS-B Out requirement. It has allowed those operators to define which missions are sensitive.

The US Army has used that exemption extensively when flying helicopters in the Washington, DC region.

On 29 July, senator Ted Cruz introduced a bill that if passed would prohibit government training flights from qualifying for the exemption. It would also require that all aircraft, within five years, have and use ADS-B In.

It's simple; the altitude restriction was never intended to be the sole method of separation. At most, it was an additional layer of protection. The controller wouldn't have cleared the Blackhawk to continue if they hadn't said they had the traffic in sight. But they did say that, whether it was true or not. ATC is a service provided to pilots, not an authority. Pilot-applied visual separation essentially overrides any procedure used by ATC. When you say "Traffic in sight," you are saying "I don't need your help maintaining separation, I have it under control and I take full responsibility."

The IFR aircraft wouldn't be required to have the traffic in sight.

And yet as we saw, this approach failed. So something has to be wrong with it.

Yet was not the controller required to inform the CRJ of the helicopter, which (as the inquiry noted) he failed to do? Thus a possible cross-check was lost.

Ward Carroll posted some thoughts about the crash following the evidence a couple of weeks ago. He gives a quick summary of the faacts, and looks at the blame game.

He's quite clear that he thinks that ATC alerting the CRJ about the presence of the helo (using visual flight separation) probably wouldn't have changed the outcome.

But he does pick up on the cockpit dynamics on PAT25. He says

"Now, the most important facts to emerge from the hearings this week center on the cockpit exchange between Warrant Officer Eves and Captain Robach that happened just about a minute before the midair. He says to her, " All right, kind of come left for me, ma'am. I think that's why he's asking ." And she replies, " Sure ." He says, " We're kinda.. ." And she cuts him off by saying, " Oh-kay, fine ." And he finishes his statement “… out toward the middle ”, meaning the middle of the river and west of helicopter route 4. So PAT 25 is above and west of where they should have been as the CRJ is properly on final approach for runway 33. Using maritime rules of the road terms, the CRJ was the burden vessel and the Blackhawk was the giveway vessel." He quotes someone (David Cherbonnier) posting:

"In military protocol, referring to a fellow officer as sir or ma'am is the role of a subordinate. It’s use in the cockpit indicated ‘privilege of rank’ as opposed to the typical instructor student relationship. The instructor was a Chief Warrant Officer with over 10 years service as an enlisted person prior to selection as a Chief Warrant Officer and as well as met all criteria to be a check pilot and as such was the person in charge during the entire training/examination exercise. In any other capacity, a Captain represents a person who has been recognized by Congress to have the qualifications to become an officer. In my experience, an examinee’s response in a drawn out “ oh-kay fine ” would have signaled check ride over. In this instance, deference was given to rank. Was that a contributing factor?"

Hopefully he knows more about aircraft rules than maritime rules. In maritime parlance (to adopt his analogy), the CRJ would be the "stand-on" vessel (expected to maintain course and speed); the Blackhawk would be the "burdened vessel", responsible for taking avoiding action (giving way).

Presumably you see the CRJ as 'limited in her ability to manoeuvre' since the Blackhawk was on her starboard side.

I skimmed through the complaint. The defendants are American and PSA (which I will refer to as the airlines) and the USA as responsible for the actions of the air traffic controllers (which I will refer to as the FAA) and for the actions of the helicopter crew (which I will refer to as the army). Perhaps somewhat notable is who is not being sued. This includes the manufacturers of both aircraft and their components and the manufacturer of the night vision goggles.

The best (in my view) argument against the airlines is that it was PSA policy that their pilots should not accept a diversion from runway 1 to runway 33 if they had not already briefed this approach (in addition to briefing the approach to runway 1). The pilot in charge hadn't done this but nevertheless accepted the diversion. This looks bad of course but there is little reason to believe that the omission of the briefing made any difference. It is also argued that the response to the TCAS conflict alert was inadequate which seems only clear in hindsight. Finally there were also insinuations to the effect that airlines should not serve busy airports because they are dangerous that I didn't find convincing.

The argument against the FAA is that the ATCs had actually violated various regulations starting with having one controller handle both helicopters and airplanes and continuing with the specific instructions and information provided to the helicopter and airplane. I suspect these purported violations are not as clear cut as claimed. In any case it is unclear they made any difference.

The argument against the army is that the blackhawk crew violated specific regulations and rules that they were required to observe. Most seriously that they were too high, knew they were too high but didn't correct this in a timely way. This clearly did make a difference and in my view if proven would be sufficient to establish liability.

I didn't notice any references to the discretionary function exception. In general the arguments against the government are based on purported specific violations of established rules and regulations by low level personnel and not on debatable broad policy decisions. The case that an army pilot doesn't have discretion to violate altitude limits seems easy to make to me. Any more than an army driver has discretion to ignore stop signs.

yes, but the local controller transmitted on both, e.g. the message where the controller told the Blackhawk to pass behind the CRJ.

From Senate Commerce Committee website, following is a summary of the ROTOR Act - Rotorcraft Operations Transparency and Oversight Reform Act. Commerce Committee vote may take place next week.
___________
Rotor Operations Transparency and Oversight Reform (ROTOR) Act
Upgrading In-Flight Safety Technology and Fixing Helicopter Operations to Eliminate Risk
[Sponsors] Senators Ted Cruz (R-TX), Jerry Moran (R-KS), Marsha Blackburn (R-TN), Ted Budd (R-NC), Shelley Moore Capito (R-WV), Roger Marshall (R-KS), Eric Schmitt (R-MO), Tim Sheehy (R-MT), Todd Young (R-IN)

The Problem : The midair collision between American Airlines Flight 5342 and an Army Black Hawk helicopter on January 29th was preventable. For decades, the airspace around the Ronald Reagan Washington National Airport (DCA) operated without an accident, but with thousands of close calls that should have resulted in preventive action. The Black Hawk was likely operating in congested airspace without transmitting Automatic Dependent Surveillance Broadcast (ADS-B) Out\x97a satellite beacon technology that can transmit location, altitude, and velocity to air traffic control and other nearby aircraft faster than radar or other transponders. The airspace is only as safe as its least equipped aircraft, which is why military aircraft must not play by different rules.

The Solution: The ROTOR Act
The ROTOR Act improves aviation safety, addresses FAA knowledge and oversight of ADS-B, and directs the Army Inspector General (OIG) to reevaluate its aviation safety practices. The bill requires:
1. All aircraft operators to equip with ADS-B In technology and transmit such information. ADS-B In is a technology for aircraft to receive location signals from other nearby aircraft and ground technology, improving safety in the sky and on runways.
2. Closes Federal Aviation Administration (FAA) loophole that permitted the Army Black Hawk to fly without broadcasting ADS-B Out. The ROTOR Act allows the FAA to only grant exceptions for \x93sensitive government missions,\x94 not training flights.
3. Requires the FAA to review helicopter routes near airports. The FAA would comprehensively evaluate the airspace at congested airports\x97where helicopters and airplanes are flying near each other\x97nationwide.
4. Directs the Army OIG to initiate a safety coordination audit. The Army Inspector General has declined to voluntarily review the Army\x92s aviation safety practices. The Inspector General would conduct an independent review of the Army's approach to safety.
5. Initiates FAA study on dynamic restricted area for helicopters near airports. The FAA would review whether audio and visual signals could be deployed to reduce airspace confusion and avoid traffic conflicts.
6. Repeals a Fiscal Year 2019 NDAA provision that exempted the Department of Defense from enacted ADS-B transmission requirements.

Why This Matters: The tragic midair collision earlier this year exposed serious and systemic weaknesses in how civilian and military aircraft share and operate in congested airspace. While the National Transportation Safety Board (NTSB) investigation continues, initial findings show glaring failures in oversight and coordination that must be addressed now, not later. The ROTOR Act was drafted in direct response to the operational shortcomings that led to the midair collision. Deconflicting congested airspace and establishing better communication standards between civilian and military aircraftis not optional\x97it is essential. The ROTOR Act does exactly that, ensuring American skies remain the safest in the world.

Recall that the accident Blackhawk flight crew likely had a Stratus 2S onboard that could have provided ADS-B traffic info via the flight crew\x92s Army-issued EFBs loaded with ForeFlight. There is no evidence from the Blackhawk CVR (or the aircraft\x92s flight path) that this feature was used.

As I recall from the interviews, there was no Army aviation policy about how this technology was to be used during DC area flights. Some crews used it, but most did not.

I think we misunderstood each other or I was was not clear enough : I was refereeing to ADS-B out not in ;
That would mainly be for the benefit of ATC .
ADS-B in, together with a CDTI, is what I said to be L So in fact we both agree .

The interview transcripts indicated that the 12th AB Blackhawk pilots used barometric altitude as the reference for flying the DC routes.
