Senators seek to change bill that allows military to operate just like before the DC plane crash

Senators from both parties pushed Thursday for changes to a massive defense bill after crash investigators and victims' families warned the legislation would undo key safety reforms stemming from a collision between an airliner and Army helicopter over Washington, D.C., that killed 67 people.

The head of the National Transportation Safety Board investigating the crash, a group of the victims' family members and senators on the Commerce Committee all said the bill the House advanced Wednesday would make America's skies less safe. It would allow the military to operate essentially the same way as it did before the January crash, which was the deadliest in more than two decades, they said.

Democratic Sen. Maria Cantwell and Republican Committee Chairman Sen. Ted Cruz filed two amendments Thursday to strip out the worrisome helicopter safety provisions and replace them with a bill they introduced last summer to strengthen requirements, but it's not clear if Republican leadership will allow the National Defense Authorization Act to be changed at this stage because that would delay its passage.

''We owe it to the families to put into law actual safety improvements, not give the Department of Defense bigger loopholes to exploit,'' the senators said.

The bill would roll back reforms

Right now, the bill includes exceptions that would allow military helicopters to fly through the crowded airspace around the nation's capital without using a key system called ADS-B to broadcast their locations just like they did before the January collision. The Federal Aviation Administration began requiring that in March. NTSB Chairwoman Jennifer Homendy called the bill a ''significant safety setback'' that is inviting a repeat of that disaster.

''It represents an unacceptable risk to the flying public, to commercial and military aircraft, crews and to the residents in the region,'' Homendy said. ''It's also an unthinkable dismissal of our investigation and of 67 families ... who lost loved ones in a tragedy that was entirely preventable. This is shameful.''

Congress may turn to another bill to fix the concerns

Senate Majority Leader John Thune said he is looking into the concerns but thinks they can be addressed by quickly passing the aviation safety bill that Cruz and Cantwell proposed last summer that would require all aircraft operators to use both forms of ADS-B, or Automatic Dependent Surveillance Broadcast, the technology to broadcast aircraft location data to other planes and air traffic controllers. Most aircraft today are equipped with ADS-B Out equipment but the airlines would have to add the more comprehensive ADS-B In technology to their planes.

That legislation would also revoke an exemption on ADS-B transmission requests for Department of Defense aircraft.

''I think that would resolve the concerns that people have about that provision, and hoping — we'll see if we can find a pathway forward to get that bill done,'' said Thune, a South Dakota Republican.

Military routinely flew without broadcasting location

Homendy said it would be ridiculous to entrust the military with assessing the safety risks when they aren't the experts, and neither the Army nor the FAA noticed 85 close calls around Ronald Reagan National Airport in the years before the crash. She said the military doesn't know how to do that kind of risk assessment, adding that no one writing the bill bothered to consult the experts at the NTSB who do know.

The NTSB's final report on the cause of the D.C. crash won't be released until next year, but investigators have already identified a number of factors that contributed, including that the helicopter was flying too high on a route that only provided scant separation between helicopters and planes landing on Reagan's secondary runway.

Homendy said part of the investigation focuses on the limitations of the various systems that are designed to alert other pilots and air traffic controllers about the location of an aircraft. The pilots of the American jet that was flying into D.C. from Wichita, Kansas, did get a warning about traffic nearby 20 seconds before the collision. But at the low altitude the plane was traveling as it prepared to land, the basic collision avoidance system recommended by this bill was partly inhibited to prevent false alarms and because there is little room to manuever.

The White House and military didn't immediately respond Thursday to questions about these safety concerns in the bill. But earlier this week Trump made it clear that he wants to sign the National Defense Authorization Act because it advances a number of his priorities and provides a 3.8% pay raise for many military members.
