FAA didn't add warning to helicopter charts, official says

NTSB Chairwoman Jennifer Homendy said an FAA working group raised concerns about all the helicopter traffic around Reagan airport and the risk of a collision in 2022, but the FAA refused to add a warning to helicopter charts urging pilots to use caution when this runway was in use.
'This is the very event that this would have been the cautionary note for,' she said.
Video and animation presented during the proceeding's first day showed the helicopter flying above the 200 feet (61 meters) altitude limit before colliding with the plane.
Investigators said Wednesday the flight data recorder showed the helicopter was actually 80 feet to 100 feet (24 to 30 meters) higher than the barometric altimeter the pilots relied upon showed they were flying. So the NTSB conducted tests on three other helicopters from the same unit in a flight over the same area and found similar discrepancies in their altimeters.

Dan Cooper with Sikorsky helicopters said that when the Black Hawk helicopter involved in the crash was designed in the 1970s, it used a style of altimeter that was common at the time. Newer helicopters have air data computers that didn't exist back then that help provide more accurate altitude readings.
Chief Warrant Officer Kylene Lewis told the board that she wouldn't find an 80 to 100 foot discrepancy between the different altimeters on a helicopter alarming because at lower altitudes she would be relying more on the radar altimeter than the barometric altimeter. Below 500 feet (152 meters), Lewis said she would be checking both instruments and cross referencing them.
Army officials said a discrepancy of 70 to 100 feet (21 to 30 meters) between the Black Hawk's altimeters is within the acceptable range because pilots are expected to maintain their altitude plus or minus 100 feet.
Concern about distances between planes and helicopters
The greater concern is that the FAA approved routes around Reagan airport that included such small separation distances between helicopters and planes when planes are landing.
'The fact that we have less than 500 foot separation is a concern for me,' said Scott Rosengren, who is chief engineer in the office that manages the Army's utility helicopters.
During the two minutes before the crash, one air traffic controller was directing airport traffic and helicopters in the area, a task that involved speaking to or receiving communications from several different aircraft, according to the NTSB's History of Flight Performance Study.

The air traffic controller had spoken to or received communications from the Black Hawk helicopter, an airplane that was taking off, an Air Force helicopter, an airplane on the ground, a medical helicopter and an inbound flight that was not the American Airlines plane that would crash.
'All aircraft could hear the controller, but helicopters could only hear other helicopters on their frequency and airplanes only other airplanes,' the report stated. 'This resulted in a number of stepped on transmissions as helicopters and airplanes were not aware when the other was communicating.'
Stepped on transmissions are those that are unheard or blocked because of other transmissions. The NTSB report provides a list of 29 separate communications between the airport tower and other aircraft during approximately the 1 minute and 57 seconds before the collision.
Previously disclosed air traffic control audio had the helicopter pilot telling the controller twice that they saw the airplane and would avoid it.
The animation ended with surveillance video showing the helicopter colliding with the plane in a fiery crash.
Investigations have already shown the FAA failed to recognize a troubling history of 85 near misses around Ronald Reagan National Airport in the years before the collision, and that the Army's helicopters routinely flew around the nation's capital with a key piece of locating equipment, known as ADS-B Out, turned off.

Broken altimeter, ignored warnings: Hearings reveal what went wrong in DC crash that killed 67
APTOPIX Aircraft Down Investigation 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. 'Are you kidding me? Sixty-seven people are dead! How do you explain that? Our bureaucratic process?' she said. 'Fix it. Do better.' 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's altimeter was wrong The helicopter was flying at 278 feet (85 meters) — well above the 200-foot (61-meter) ceiling on that route — 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's final report will be done next year, but there likely will not be one single cause identified for the crash. 'I think it was a week of reckoning for the FAA and the U.S. Army in this accident,' 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. 'The fact that we have less than 500-foot separation is a concern for me,' said Scott Rosengren, chief engineer in the office that manages the Army's 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's 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's air traffic control organization, said he thinks controllers at Reagan 'were really dependent upon the use of visual separation' to keep traffic moving through the busy airspace. The NTSB said controllers repeatedly said they would just 'make it work.' They sometimes used 'squeeze plays' 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's 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 'helicopter 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.' 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 'every sign was there that there was a safety risk and the tower was telling you that.' But after the accident, the FAA transferred managers out of the airport instead of acknowledging that they had been warned. 'What 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,' Homendy said.
