737-900

[arcodelta]

Hi everybody,

first of all: greatest place for 737 topics all around... thanks!

and then a really small question:
I've a license on 737-6/7/8 but no reference to 737-900... so, my National Authority may want me to make a 'new' course... what differences are there between -800 and -900?

I've checked AMM (but my company has no -900, so: no clue). Then I think about the FCOM, so I've checked it and seee just minor (training) differences: a couple things about engine type rating, some about IAS vs flap position and a Type ii door just around the wing.

any clue?

When you did the 737NG course, you should be certified for all NG types, including -900.
Indeed the differences you mentioned are there. Also the engine rating is higher (26K) then an -800 (24K).
I cannot see any problem why your authorities would ask you to do another course, because there is no other course. The NG type course consists mostly of Part 1 of the AMM. And that includes -600 till -900 types.
Small changes and company related items on your a/c should be given as a continuation training point by your own company.
Hope these aswers help you a bit.

Yes, I think it should be so... and I'm trying to convince them.

So, the only differences are this ''very minor'' engine/perfomance related and the door. right?

[sjap]

Yep, except for the door. The extra door is mounted on the new -900, the -900X only.
The normal -900 has the same doors as the previous NG versions.

Another difference between the -900 and other NGs is the Hydraulic 2 position tailskid, that extends for take off and landing. The control is contained within the Supplemental PSEU ( SPSEU ) which is in J23 box EE bay. The Mid Cabin Doors are also monitored through the SPSEU.
