792 Boom Supersonic XB-1 Demonstrator

The milestone reached by Boom Supersonic with their XB-1 demonstrator and the recent leadership changes at Boeing, including the resignation of CEO Dave Calhoun. Also, the FBI contacted the passengers of Alaska Airlines Flight 1282, quality issues with Boeing MAX jets, FAA oversight of United Airlines, engine issues with Pratt & Whitney, and the farewell tour of the A-10 demonstration team. Aviation News Boom Announces Successful Flight of XB-1 Demonstrator Aircraft The XB-1 supersonic jet demonstrator flew from the Mojave Air and Space Port. Boom Supersonic calls it the world’s first independently developed supersonic jet. The XB-1 incorporates carbon fiber composites, advanced avionics, digitally-optimized aerodynamics, and an advanced supersonic propulsion system. Boom said the “XB-1 met all of its test objectives, including safely and successfully achieving an altitude of 7,120 feet and speeds up to 238 knots (273 mph). While XB-1 was in the air, the team performed an initial assessment of the aircraft’s handling qualities, including airspeed checks with the T-38 chase aircraft, and assessing the aircraft’s stability in the landing attitude (at a high angle of attack).” Boom’s supersonic airliner Overture “…will carry 64-80 passengers at Mach 1.7, about twice the speed of today’s subsonic airliners. Overture is designed to run on up to 100% sustainable aviation fuel (SAF).” Video: Full Video: XB-1 Takes Flight https://youtu.be/2aT4okUYPoI?si=2aGGuyeSkZo3wmtS Boeing C.E.O. to Step Down in Major Reshuffle at Embattled Plane Maker Boeing announced leadership changes: CEO Dave Calhoun leaves at the end of 2024 Stan Deal, the head of Boeing commercial planes left immediately Stephanie Pope, Boeing’s COO, replaces Stan Deal. Board Chairman Larry Kellner will not stand for re-election. Steve Mollenkopf was elected by the board to be the new chairman.

Alaska Airlines Flight 1282 passengers receive FBI letter identifying them as the victims of a possible crime Attorney Mark Lindquist represents passengers who were on Alaska Airlines Flight 1282 when the door plug blew out. He shared a letter from the FBI’s Seattle division under the Justice Department that he says was received by the passengers he represents. The letter says “I’m contacting you because we have identified you as a possible victim of a crime.” Boeing Charged with 737 Max Fraud Conspiracy and Agrees to Pay over $2.5 Billion The DOJ press release from 2021 describes the conditions of the Boeing deferred prosecution agreement. In part: “The Boeing Company (Boeing) has entered into an agreement with the Department of Justice to resolve a criminal charge related to a conspiracy to defraud the Federal Aviation Administration’s Aircraft Evaluation Group (FAA AEG) in connection with the FAA AEG’s evaluation of Boeing’s 737 MAX airplane.” “The tragic crashes of Lion Air Flight 610 and Ethiopian Airlines Flight 302 exposed fraudulent and deceptive conduct by employees of one of the world’s leading commercial airplane manufacturers…” “Boeing’s employees chose the path of profit over candor by concealing material information from the FAA concerning the operation of its 737 Max airplane and engaging in an effort to cover up their deception. This resolution holds Boeing accountable for its employees’ criminal misconduct, addresses the financial impact to Boeing’s airline customers, and hopefully provides some measure of compensation to the crash-victims’ families and beneficiaries.” FAA wants inspections of Boeing Max planes for wiring flaws that could lead to ‘loss of control’ A recent FAA proposed airworthiness directive would require the inspection of about 207 737 Max airplane wings for wiring damage within three years. The Agency says an “unsafe condition” could result in a “loss of control” of certain Boeing 737 Max jets due to the “nonconforming” installation of spoiler control wires. FAA to increase oversight of United Airlines after recent issues Oversight of United Airlines by the FAA is increasing after recent incidents. The airlines vice president of corporate safety, Sasha Johnson said in a memo to employees that the “number of safety-related events in recent weeks have rightfully caused us to pause and evaluate whether there is anything we can and should do differently.” The FAA will review some work processes, manuals, and facilities. Johnson said, “We welcome their engagement and are very open to hear from them about what they find and their perspective on things we may need to change to make us even safer.” United Airlines Faces Closer F.A.A. Scrutiny After Safety Incidents FAA to United: no new planes routes, or pilots FAA responds to PW1100G ‘misaligned’ vane issue that caused a 2022 failure A “blisk.” Image by Olivier Cleynen. In 2022, the low-pressure compressor first-stage integrally bladed rotor (or “blisk”) in an Airbus A320neo engine failed, resulting in an engine shutdown. In a proposed rule, the FAA wants to require that airlines replace the rotor. Pratt & Whitney says “The [proposal] relates to a known issue that affected a limited number of engines and is unrelated to powder metal. The improved hardware has been deploying to the fleet over the past two years through previously released service bulletins.” According to the FAA, a “misaligned” inlet guide vane ahead of the low-pressure compressor resulted in “aerodynamic excitement,” which caused the rotor to fail. Improvements made by Pratt & Whitney include redesigns of the arm assembly and the first-stage integrally bladed rotor.
