Boeing Falls 6.6% as FAA Delays 737 MAX 10 Certification

The delay matters less for the software issue itself than for what it signals about the FAA's posture toward Boeing's certification pipeline, which has been the company's binding constraint rather than demand. The read-across is to suppliers and airlines whose fleet plans assume MAX 10 deliveries on a certain timeline, and to whether this becomes a scheduling adjustment or another open-ended review. Whether the FAA's scrutiny broadens to other MAX variants is the question the market is now pricing.
