MEMORANDUM OPINION AND ORDER

This case is one of dozens brought by family members or other representatives of passengers who were killed in the tragic airplane crash of Ethiopian Airlines ET 302 on March 10, 2019. Plaintiffs, Michael Stumo and Nadia Milleron, as personal representatives of the estate of their deceased daughter Samya Stumo, assert claims against the Boeing Company (“Boeing”), the manufacturer of the aircraft, as well as two of Boeing’s suppliers, Rosemount Aerospace, Inc. (“Rosemount”), and Rockwell Collins, Inc. (“Rockwell”) (collectively, “Suppliers”), and two of Boeing’s former CEOs, Dennis Muilenburg and David Calhoun. Boeing has admitted liability for compensatory damages, and the other defendants now move to dismiss the claims against them. For the following reasons, their motions are granted. I. Background The following is a brief summary of the allegations of the operative First Amended Complaint (ECF No. 1326) that are material to the present motions. The ET 302 aircraft was a Boeing 737 MAX 8, one of a family of airplanes that Boeing

began to develop in 2011. To speed the process of obtaining Federal Aviation Administration (“FAA”) approval, Boeing essentially reused the same 737 design it had been using for decades, but it developed new engines that were more fuel-efficient. Because the new engines were larger, the 737 MAX 8 handled differently than its 737 predecessors. To avoid the inevitable delays that would come from either redesigning the product or retraining pilots, Boeing developed the Maneuvering Characteristics Augmentation System (“MCAS”), a flight-control system that altered the 737 MAX 8’s handling to mimic that of previous versions of the 737. The MCAS system incorporated software code written by Rockwell and sensors supplied by Rosemount. When the sensors detected that the nose of the aircraft pitched upward, as it sometimes did due to the aerodynamic instability caused by the larger engines, the

system automatically pushed the nose of the aircraft back down in order to stabilize the aircraft. On October 29, 2018, Lion Air Flight 610, a flight operated by a Boeing 737 MAX 8, crashed into the Java Sea shortly after takeoff from an Indonesian airport. In the days after the crash, Indonesian authorities released black-box data showing that the aircraft’s nose dipped twenty-four times during the short flight. The plane’s sensor had malfunctioned, feeding erroneous pitch data to the MCAS system, which unnecessarily forced the plane’s nose down at low altitude. The pilots struggled to regain control, but they were unable to prevent the crash. Muilenburg contacted the Boeing Board of Directors, of which Calhoun was then a member, on November 5, 2018, to discuss the crash. By the following day, the FAA had conducted a safety assessment concluding that the erroneous sensor data causing the plane repeatedly to pitch downward was a “likely significant contributing factor” in the crash. (Am. Compl. ¶ 210, ECF No.

1326.) Calhoun stated that the Board viewed the crash as an anomaly. Muilenburg stated in a FOX Business TV interview that information about the MCAS system was available to pilots and air carriers, and the 737 MAX 8 could be flown safely. Plaintiffs assert that these statements were false: they claim that the Board knew that the MCAS system was defective and it was a matter of time before there was another accident, and Muilenburg knew that Boeing had not been forthcoming with extensive information about the MCAS system, fearing that doing so might jeopardize FAA approval and spook customers. Muilenburg and the Board took no actions to ground the 737 MAX 8, and, according to Plaintiffs, they treated news stories about the aircraft and its MCAS system as nothing more than a “public-relations problem.” (Am. Compl. ¶ 242.)

They continued to resist any suggestion that the 737 MAX 8 could not be flown safely, until the FAA grounded the fleet months later, in the wake of the ET 302 crash. Ms. Stumo was one of the passengers on ET 302, which experienced problems similar to those that had caused the Lion Air crash months earlier. A damaged sensor caused the MCAS system to trigger unnecessarily, pushing the nose of the plane downward shortly after takeoff from Addis Ababa, Ethiopia. The pilots struggled to regain control of the aircraft, but they were unsuccessful, and the plane crashed after traveling only approximately thirty miles. All passengers and crew were killed in the crash. Plaintiffs filed this case soon after. In January 2020, during the pendency of this case, Calhoun became CEO of Boeing. II. Procedural History The cases arising out of the ET 302 crash have been consolidated before the undersigned judge. The plaintiffs initially asserted products liability claims against Boeing, Rosemount, and Rockwell. In November 2021, the parties in almost every case stipulated to Boeing’s liability for

any duly proven compensatory damages and to dismiss the Suppliers. (See Agreed Stipulation of the Parties, ECF No. 1217-1; Agreed Order, ECF No. 1220.) This case is one of only a couple in which the plaintiffs abstained from the stipulation. In February 2022, Plaintiffs sought leave to file an amended complaint to add claims against the CEOs. Boeing responded by filing a motion asking the Court to accept its election not to contest liability in this case, even absent any stipulation. If the Court granted the motion, Boeing argued, then it followed that the Court should bar any discovery or proceedings addressing liability, dismiss the claims against the Suppliers as moot, and deny Plaintiffs leave to amend the complaint to assert claims against the CEOs. Plaintiffs opposed the motion, arguing, in pertinent part, that Boeing’s concession as to liability for compensatory damages did not resolve Plaintiffs’

proposed claims against the CEOs, nor did it resolve their claims for punitive damages against the Suppliers or any other defendants. The Court granted Boeing’s motion as to the request that Plaintiffs be precluded from taking discovery or presenting evidence on Boeing’s liability, ruling that there was no genuine controversy over the issue due to Boeing’s concession. The ruling was based in part on the Court’s conclusion that the law of either Illinois (the state in which Boeing was headquartered) or Washington (the state of Boeing’s principal place of business) applies to the issue of Boeing’s punitive damages, and neither state permits punitive damages under the circumstances of this case. Because punitive damages are not available to Plaintiffs, the Court reasoned, no purported pursuit of punitive damages provides any proper basis for Plaintiffs to develop and present evidence of Boeing’s liability. However, the Court denied Boeing’s motion as to dismissal of the claims against the Suppliers, reasoning that the Suppliers are domiciled in states—Minnesota and Iowa—where punitive damages are available, and Boeing had not demonstrated that the law of those states could

not possibly apply to the Suppliers on that issue. The Court also denied Boeing’s motion as to amending the complaint to add claims against the CEOs, explaining that Boeing had not yet shown that any claims against them would certainly be futile.
