Boeing 737-900ER: Second model to be inspected after 737 Max 9 blowout

Checks are to be carried out on a second Boeing aircraft model following the blowout of an unused door on one of its planes earlier this month.

The US Federal Aviation Administration grounded more than 170 of the 737 Max 9 fleet after a cabin panel broke away thousands of feet above the ground.

On Sunday, the agency said airlines should also inspect older 737-900ER models, which use the same door design.

The FAA described the move as an “added layer of safety”.

It said there had been no reported issues with the 737-900ER, but that it uses the same style of panel to “plug” an unused door as the plane involved in the terrifying 5 January incident.

So what they’re saying is after the first one blew out, they only grounded half of the affected planes because… Boeing is evil and FAA is toothless?

There is no evidence the 900ER is affected yet, and a small amount of evidence that it isn’t affected. Thats what this check is for, to know for sure one way or the other.

I prefer to err on the side of not getting sucked out of an aircraft.

If it has the same failing door plugs, we should assume it is affected until proven safe.

It’s surprising that it took them this long, considering it’s the exact same plug type as the 737-MAX 9.

The 737-900ER has been flying since 2007 (so 17 years ago) and never had this issue, whereas the 737-MAX 9 just started flying in 2018 (so 6 years ago). The evidence on the recovered door suggests it isn’t a design problem but rather an assembly problem. If indeed it is an assembly problem that existed 17 years ago too, then its much more likely that the older planes would have already had the failure the Max 9 experienced.

There’s also the practical impacts that this FAA notice brings. Boeing 737 comprises a huge amount of the worlds passenger airline capacity. The immediate requirement grounding Max 9 jets took a big chunk of air capacity offline. It takes time for maintenance crews to work through those. Making the same requirement for 737-NG (of which the 900ER is one) would mean those planes wouldn’t be flying either and sitting parked waiting for the maintenance crews to work through the Max 9 backlog.
