276:, which considerably reduced the length of the forward strut as well as being them a slender and somewhat elegant shape. As per convention amongst monoplanes of the era, the undercarriage was principally stressed in the axial direction. The axles were composed of high-tensile steel and were intentionally shaped as to ensure maximum rigidity as well as minimising weight. These axles were positioned at the ends of struts hinged to the fuselage at the planes of symmetry which reduced the lateral motion of the wheels to a minimum. Each axle incorporated a device that minimised the braking stresses imposed on the whole assembly; the brakes were controlled either by hand or via the 493: 447: 177:
cabin. The transverse frames and side walls of the fuselage were constructed in a manner that provided ample unobstructed spaces and permitted the use of relatively large doors without incurring excessive external dimensions. A total of four doors were present, two on each side of the fuselage; this was felt to increase the aircraft's safety level. A specialised device was present to overcome any difficulties in the opening of the doors during flight, better facilitating the occupant's emergency egress.

while the third rod, which carried a shock absorber composed of rubber disks inside the fuselage, was aligned vertically. The lower end of the third rod was hinged to the top of the skid, which had a spoon-shaped show with a guiding rib. This style of skid was somewhat unorthodox and was claimed to be less prone to digging into the ground.

Directly behind the pilot' seat was a sizable baggage compartment, the variable weight of which could be easily offset via adjustments of the aircraft stabilizer. Structurally, the fuselage, wing and tail surfaces were all supported by a tubular framework made entirely of
