A fiery January crash of a B-1 bomber in South Dakota was caused by multiple crew failures, terrible winter weather and a last-minute brush with wind shear that resulted in all four members ejecting and the total loss of the $450 million warplane, Air Force Global Strike Command said Thursday. The command’s report was unusually blunt in describing what the investigation uncovered about the crews involved in the evening crash at Ellsworth Air Force Base. The investigators said the crash exposed an “organizational culture that tolerated decaying airmanship skills, a lack of discipline, poor communication, and inadequate focus on regulations.” The report is what is used to inform Air Force decisions on disciplinary action, so it is not yet clear whether any of the crew or their leaders will be disciplined as a result of the crash. The B-1 is one of three long-range U.S. bombers. The supersonic aircraft carries conventional weapons and is capable of taking off from the U.S. to strike targets overseas in a single mission. The aging warplane is being maintained by the Air Force until the new B-21 Raider stealth bomber comes online. On the night of the accident, the B-1 was the second of two bombers on a training flight that were about to land in quickly deteriorating winter weather. While both bombers came in too low for the weather they were facing, the first was able to correct its speed and altitude to land in visibility so poor the control tower could see neither the bomber nor its taxi lights once it landed. The second bomber also came in too low, but inside the cockpit, the crew was not doing what was required — relaying specific communications to one another and taking responsibility to monitor and cross-check the aircraft’s instrument readings to ensure they maintained the needed speed, altitude and descent. In the final 55 seconds of flight, the bomber encountered wind shear, and the pilot’s reactions resulted in the aircraft losing too much power. But neither the pilot nor a supervisory instructor pilot caught that in time, because they were looking outside the aircraft instead of monitoring their instruments, and the required communications that might have caught the error did not occur. Another crew member responsible for assisting with cross-checking testified they were reading a post-landing checklist instead of backstopping the instruments, the investigators found. The flight became unrecoverable. As the B-1 hit the ground short of the runway all four crew members successfully ejected. Almost every part of the flight exposed problems, even the ejection, the investigation found. While the scathing report has suggested there may be larger issues at Ellsworth to address, it also has raised questions on whether continued strain on personnel, resources and aircraft availability — an issue that military aviation overall is facing — played a role. Primarily, communication and supervision had eroded not only inside the crashed bomber, but also within its squadron and even from the control tower. A pre-flight squadron brief did not include a key advisory that required the crews to approach at a higher altitude, given the lost visibility, and investigators found that none of the eight aviators aboard the two bombers knew the Air Force’s instructions for the cold weather they were flying in. There was a “willful disregard” for the […]
