That is a gravel kit for remote airports....the nose gear well is revised to fit the the kit that is fitted behind the gear

Also note the little skids on the bottom of the engine inlets. These are vortex generators to blow debris out of the way, right?

The little pieces that stick in front of the engines are vortex dissipators. If you see the 737-200 on a wet runway, you can sometimes see a vortex of water entering the engine. Because these planes were for use out of gravel strips, the dissipators break up the vortex and prevent gravel from being ingested into the engines. CP's examples of this type also have a ADF antenna running from the tail to the fuselage. I think it's a sense antenna, I always get mixed up between sense and loop antennaes. These are found on the 737-200 combi.

Nothing......Everybody else beat me to identiting the gravel kit........

I do want to add that kit is the reason why Alaska will not be retiring the 737-200's anytime soon.......They are operated as combis up here and pull some really serious duty...........The rumor is that Alaska has had the money in the bank since they bought 746 to get another -200 combi but none have come on the market.........

I believe this "kit" (nose wheel plate that prevents stones being picked up and thrown into the engines by the nose wheel, and the inlet dissipators) was designed by Pacific Western in the early 70's for use on northern Canada gravel strips. Or perhaps it was Nordair. Regardless, both operators used this 737-200 mod extensively for 25 years.

If anyone cares, I understand that after trying several exotic materials for the nose gear gravel deflector, it was decided that good ol' mahogany wood gave the best performance!

No high tech molybedinum-kryptonite-inconel alloys could handle the beating as well as a piece of wood.

Just 2024 Aluminum

I don't recall the door being wood.....Just standard 2024 Alcad aluminum.....

Not to say I couldn't be completely off my rocker......I wasn't paying that much attention to what the door was made out of when I was hooking towbars up to those aircraft..

I'm referring to the gravel deflector which wraps around the nose wheels.

Perhaps the Alaskan mechanic was pulling one, but it sure seemed very, very stout, almost like a forged part.

Anyone out there got more info???
