Boeing is close to approval of 737 MAX's anti-ice fix. This will pave the way for delivery.

Boeing executives have said that the company is nearing the 'final stages' of obtaining regulatory approval for a fix to the engine anti-ice systems on its 737 MAX jetliner. This will pave the way for the much-delayed MAX 7 & 10 versions entering service. The redesign addresses a problem that could cause engine failure or overheating. It was the main obstacle to the certification of Boeing's smallest and biggest versions. Cirium, an aviation analytics firm, reports that Boeing has built 30 MAX 7s already and nine MAX 10s are awaiting delivery. At least 28% (or more) of the outstanding MAX orders are for the larger MAX 10. In May, the U.S. Federal Aviation Administration announced that it would certify the smaller 737 MAX7 this summer. Southwest Airlines is by far the largest customer of this?version.

Executives told reporters that the MAX 10's certification flight tests are 98% more profitable than other aircraft.

Chris Payne said that the 737 MAX program vice president and general manger for Boeing development programs, Chris Payne, stated, "We only have two more flight tests to do and should be finished very soon."

Years behind schedule

The MAX 7 & 10 are years behind schedule in their certification, which has enabled Airbus to increase its market share.

Boeing had to undergo a stricter certification process after two fatal MAX 8 accidents in 2018 and 2019 as well as scrutiny on the company's quality and production systems following a mid-air panel blowout that occurred on a near new Alaska Airlines MAX 9 in January 2024.

Boeing was allowed to continue making the MAX 8, 8200, and 9 variants after the issue with the anti-ice systems was discovered by regulators in 2021. However, certification for the other versions of the MAX aircraft were delayed.

Mike Sinnett is Boeing's senior Vice President of Product Strategy, Product Development and Development Programs. He said that the fix for the system reduces engine noise as well as fan flutter.

He said, "It was a win-win situation for everyone."

CFM International is a joint venture between GE Aerospace, France's Safran and CFM International to produce the LEAP-1B engines for the 737 MAX. Boeing claims that the majority of the retrofitting can be completed in a single maintenance shift for the existing MAX fleet. However, it will require new wiring, which is more intrusive.

Boeing executives said they were working with regulators to develop a schedule allowing airlines to repair their planes while the aircraft are in the hangar undergoing 'heavy maintenance checks', thus reducing costs and disruption.

MAX 10 will have an upgraded flight crew alerting system called an enhanced angle of attack system to meet the safety requirements set by Congress after the two MAX crashes in which 346 people were killed, and led to the model being grounded for 20 months starting in 2019.

The system simplifies the flight-deck notifications that resulted from a faulty angle-of attack sensor. This caused pilots to be overwhelmed with information prior to the crashes in Indonesia and Ethiopia. Bill Quashnock said that the update was "an IOU" from the return to service (requirements), after the unfortunate accidents.

He said that the new system will be installed on all 737 MAX jets?within 2 years of regulators certifying it.

Boeing has also completed more than half of the certification flight tests for the 777-9, and is on track to begin delivering this new widebody jet in the next year. This was confirmed by Terry Beezhold. Boeing Vice President and General Manager of the 777-9 Program.

The company has yet to meet several certification requirements. This includes getting regulatory approval for flights that travel long distances with only a few airports between. Reporting by Dan Catchpole, Seattle; editing by Jamie Freed
