Multi-class 737-900: Who De-boards First?

Sun Apr 03, 2016 8:00 pm

I recall reading in a topic that passengers in the last rows need to disembark first on the 737-900 in order to avoid tipping the tail. Does my memory trick me?
If not, then it is quite a cumbersome trait of the type especially when there is an F/C class aboard where the premium passengers would definitely like to have the privilege of de-boarding first. Is there policy at any airlines operating the 739 addressing this?

Every 739 I've ever been on has had the normal front-first disembarking style.

The aft cargo pit needs to be unloaded first. If they unload the front cargo put first and there are only passengers in the back getting off, there is a risk for tipping. The ramp crews need to be more careful with the 900.
If you have never designed an airplane part before, let the real designers do the work!

I've flown on at least 30-40 739ER sectors and haven't once had an issue with having to deplane in a different way. My understanding is that ramp crews that pay attention are generally going to handle it just fine.

Alternatively some airlines are just using a wooden stick to prop up the tail

Here is more about the tailstands for 737-900s:

Beside UA, there is another airline currently introducing tailstands for the 737-900 to prevent tipping. I think it is Alaska.

While I understand the need to expedite your more valuable customers, I think safety is paramount. Safety also projects on the reputation of a company.

The tipping problem on the 737-900 is being over hyped, the same problem existed with older designs including the stretch DC-8, 727-200 and in some rare cases the DC-10 and 747. No need to deplane the rear passengers first, just unload the rear cargo/baggage hold before the front and the airplane should remain balanced. If not, tail stands/sticks have been used on all, although the 727 hydraulic over center struts on the tail stairs would suffice instead.

Flew through SEA last month and nearly every 739 I saw had a tail stand

I flew on a DL 739 in Aug 2015 DCA to DTW. The flight was packed. When the ramp crew went to remove the pole from the tail, it was stuck and they couldn't remove it for pushback.
The captain had passengers, starting from the rear, leave their seats and keep moving into the jetway until enough weight was moved. It took about 8-10 rows of people to leave their seats until the ramp crew was able to get the pole to budge. The whole thing caused just about an hour delay. The captain acknowledged that the 739 was the newest plane in the DL fleet... and that ground crews were still getting accustom to handling it.

There was a thread about it not too long ago.

I can't recall ever seeing a tail stand used on stretch DC-8s in passenger service.
