The main landing gear consists of separate left and right side heat-treated (7075-T651) alu-
minum spring legs, which are bolted to a square tube truss in the bottom of the fuselage struc-
ture. No maintenance is required. However, since the landing loads are taken on these mem-
bers, they are stressed and should be inspected frequently for damage and corrosion. See Sec-
tion II, “Inspection Guides”.
