Hello.For some reason, the landing gear will not retract the regular -700 model, and the -700 w/Airstairs. It will retract on the other models (-700 w/Winglets, and the -800/900s). Any help please? Thank you.David Brown

You have all the Hyd. pumps on??? And you cleared all fail. menu???Or you just have some things stuck in the landing gear which is the cause that the landing gear wond retract the only thing you can do is make a emergency landing.PS. That the landing gear won't retract is better then it won't extend which I had one time. :) ;)
