[NSRCA-discussion] BOLLY out of business

[Ron Van Putte]

One problem with swept gear hasn't been mentioned.  If an airplane  
drops into the runway, as they sometimes do for many of us, the load  
is vertically applied to the gear/mounting plate on a straight gear.   
However, on a swept gear, there is also a nose-down bending moment,  
which is a function of the sweep angle.  Airplanes with swept landing  
gears must have beefier (heavier) mounting plate attachment.
