Boeing Faces Investor Probes Over MAX 10 Certification Delay

The Boeing Company (Ticker: BA) is facing at least two investor investigations after federal regulators delayed certification of the long-awaited 737 MAX 10 due to a software problem.

The Federal Aviation Administration (FAA) announced on September 28 that it would delay certification until the issue, involving automated flight guidance, is resolved. The software can cause the aircraft's vertical navigation function to disengage under specific circumstances, increasing pilot workload during go-arounds.

Boeing shares plummeted nearly 7% in a single trading session following the announcement, with the stock falling $13.68 to close at $184.39. Two law firms, Pomerantz LLP and Bronstein, Gewirtz & Grossman LLC, have announced investigations into potential securities claims tied to the MAX software disclosure and subsequent certification delay.

The FAA has not determined that the software issue constitutes a safety-of-flight problem, but is convening a Corrective Action Review Board to examine the matter. Boeing reportedly knew about the issue in 2024, but did not consider it a safety concern at the time. The company informed 737 operators about the issue and is developing a permanent software update.
