Over three days of sometimes contentious hearings this week, the National Transportation Safety Board interrogated Federal Aviation Administration and Army officials about a list of things that went wrong and contributed to a Black Hawk helicopter and a passenger jet colliding over Washington, D.C., killing 67 people.

The biggest revelations: The helicopter’s altimeter gauge was broken, and controllers warned the FAA years earlier about the dangers that helicopters presented.

At one point NTSB Chairwoman Jennifer Homendy scolded the FAA for not addressing safety concerns.

鈥淎re you kidding me? Sixty-seven people are dead! How do you explain that? Our bureaucratic process?鈥� she said. 鈥淔ix it. Do better.鈥�

Victims of the January crash included a group of elite young figure skaters, their parents and coaches and four union steamfitters from the Washington area.

Here is a look at the major takeaways from the hearings about the collision, which alarmed travelers before a string of other crashes and close calls this year added to their worries about flying:

The helicopter鈥檚 altimeter was wrong

The helicopter was flying at 278 feet (85 meters) 鈥� well above the 200-foot (61-meter) ceiling on that route 鈥� when it collided with the airliner. But investigators said the pilots might not have realized that because the barometric altimeter they were relying on was reading 80 to 100 feet (24 to 30 meters) lower than the altitude registered by the flight data recorder.

The NTSB subsequently found similar discrepancies in the altimeters of three other helicopters from the same unit.

An expert with Sikorsky, which makes the Black Hawks, said the one that crashed was an older model that lacked the air data computers that make for more accurate altitude readings in newer versions.

Army Chief Warrant Officer Kylene Lewis told the board that an 80- to 100-foot (24- to 30-meter) discrepancy between the different altimeters on a helicopter would not be alarming, because at lower altitudes she would be relying more on the radar altimeter than the barometric altimeter. Plus Army pilots strive to stay within 100 feet (30 meters) of target altitude on flights, so they could still do that even with their altimeters that far off.

But Rick Dressler of medevac operator Metro Aviation told the NTSB that imprecision would not fly with his helicopters. When a helicopter route like the one the Black Hawk was flying that night includes an altitude limit, Dressler said, his pilots consider that a hard ceiling.

FAA and Army defend actions, shift blame

Both tried to deflect responsibility for the crash, but the testimony highlighted plenty of things that might have been done differently. The NTSB鈥檚 final report will be done next year, but there likely will not be one single cause identified for the crash.

鈥淚 think it was a week of reckoning for the FAA and the U.S. Army in this accident,鈥� aviation safety consultant and former crash investigator Jeff Guzzetti said.

Army officials said the greater concern is that the FAA approved routes around Ronald Reagan International Airport with separation distances as small as 75 feet (23 meters) between helicopters and planes when planes are landing on a certain runway at Reagan.

鈥淭he fact that we have less than 500-foot separation is a concern for me,鈥� said Scott Rosengren, chief engineer in the office that manages the Army鈥檚 utility helicopters.

Army Chief Warrant Officer David Van Vechten said he was surprised the air traffic controller let the helicopter proceed while the airliner was circling to land at Reagan鈥檚 secondary runway, which is used when traffic for the main runway stacks up and accounts for about 5% of flights.

Van Vechten said he was never allowed to fly under a landing plane as the Black Hawk did, but only a handful of the hundreds of times he flew that route involved planes landing on that runway. Other pilots in the unit told crash investigators it was routine to be directed to fly under landing planes, and they believed that was safe if they stuck to the approved route.

Frank McIntosh, the head of the FAA鈥檚 air traffic control organization, said he thinks controllers at Reagan 鈥渨ere really dependent upon the use of visual separation鈥� to keep traffic moving through the busy airspace. The NTSB said controllers repeatedly said they would just 鈥渕ake it work.鈥� They sometimes used 鈥渟queeze plays鈥� to land planes with minimal separation.

On the night of the crash, a controller twice asked the helicopter pilots whether they had the jet in sight, and the pilots said they did and asked for visual separation approval so they could use their own eyes to maintain distance. Testimony at the hearing raised serious questions about how well the crew could spot the plane while wearing night vision goggles and whether the pilots were even looking in the right spot.

The controller acknowledged in an interview that the plane鈥檚 pilots were never warned when the helicopter was on a collision path, but controllers did not think telling the plane would have made a difference at that point. The plane was descending to land and tried to pull up at the last second after getting a warning in the cockpit, but it was too late.

FAA was warned about the dangers of helicopter traffic in D.C.

An FAA working group tried to get a warning added to helicopter charts back in 2022 urging pilots to use caution whenever the secondary runway was in use, but the agency refused. The working group said 鈥渉elicopter operations are occurring in a proximity that has triggered safety events. These events have been trending in the wrong direction and increasing year over year.鈥�

Separately, a different group at the airport discussed moving the helicopter route, but those discussions did not go anywhere. And a manager at a regional radar facility in the area urged the FAA in writing to reduce the number of planes taking off and landing at Reagan because of safety concerns.

The NTSB has also said the FAA failed to recognize a troubling history of 85 near misses around Reagan in the three years before the collision,

NTSB Chairwoman Jennifer Homendy said 鈥渆very sign was there that there was a safety risk and the tower was telling you that.鈥� But after the accident, the FAA transferred managers out of the airport instead of acknowledging that they had been warned.

鈥淲hat you did is you transferred people out instead of taking ownership over the fact that everybody in FAA in the tower was saying there was a problem,鈥� Homendy said. 鈥淏ut you guys are pointing out, 鈥榃elp, our bureaucratic process. Somebody should have brought it up at some other symposium.鈥欌��
