Boeing 737 max 10 certification delayed again

Snow1964 · 29 Sep 2026

Seems the 737 max 10 has been delayed, and Boeing shares dropped 6% yesterday

That will seriously affect Ryanair which has 150 planes on order (plus 150 options) with delivery supposed to start early 2027, in a 228 seat configuration. The last of Ryanair max 8-200 orders were delivered months ago, so will basically have to either do major overhauls on older planes to keep them operational longer, or shrink the fleet.

Ryanair should have switched to A321 NEOs, just like Jet2.

The A321s are massively backordered anyway. But I suppose they are at least certified!

There are also issues with engines which have grounded some of those already produced.

Also Ryanair would face huge cost and disruption re-training all their staff, much more so than the conversion training needed to go from the 737NG to the Max. And ensuring that the flow of trained pilots matches the rate of delivery of the aircraft and everyone who has currency on both types gets enough flying time to retain it.

This is something Ryanair (and other airlines flying mainly a single type) will have to face when the 737 and the A32x are eventually superseded, but I imagine they'd rather not do so now.

Easyjet made the switch from Boeing to Airbus years ago. Jet2 are making the switch now. As you indicate, there are very good reasons why Ryanair has stuck with Boeing, but it is giving them problems.

I do get the feeling that Boeing is going a 'stretch too far' with the 737-MAX10; indeed, with the bodge-job they've done with the latest series of the plane, to use an American colloquialism, perhaps the 737 is 'maxed out'.

It probably is, yes. But that decision was made over a decade ago when the market looked a lot different than it does now. The whole reason for going with the 737 Max rather than a clean-sheet design was that it was supposed to be just another 737 variant - which means that going from say a 737-800 to 737 Max 10 would just be a couple of hours of differences training. Indeed that was the reason for the infamous MCAS system - it was so that the Max with its larger, further-forwards engines would handle the same as a 737NG.

Had things gone to plan it would've been seen as a smart move.

Rumours from US that max 10 certification will occur in next few days

Boeing and the Federal Aviation Administration on Friday morning held a type certification board meeting (TCBM), the final step before the long-awaited regulatory approval of the 737 Max 10, according to three people familiar with the milestone.

Following the completion of the TCBM, which The Air Current is told was successful, Boeing is expected to deliver a project statement of completion (PSOC) to the FAA prior to ceremonial signatures that are expected to come as early as next week. The 737 Max 7’s TCBM was also held on a Friday and the aircraft’s type certificate was formally signed by Boeing the following week on Aug. 3.

Ryanair might therefore get some next Spring
First ones are reported registered EI-HTA, HTB etc
