Cessna 172

The Cessna 172 aircraft is an all metal construction with high wing design.
The aircraft is fitted with single engine on the nose of the aircraft.
The seating capacity of the aircraft is four
The landing gear design is a tricycle type (means one wheel is fitted on the nose)   

The construction of the fuselage is a conventional formed sheet metal bulkhead, stringer, and skin design referred to as semimonocoque.

Major items of structure are the front and the rear carry through spars to which the wings are attached, a bulkhead and forgings for main landing gear attachment at the base of the forward door posts for the lower attachment of the wing struts. Four engine mount stringers are also attached to the forward door post and extended forward to the firewall.

The externally braced wings, containing integral fuel tanks, are constructed of a front and rear spar with formed sheet metal ribs, doublers, and stringers. The entire structure is covered with aluminium skin. The front spars are equipped with wing to fuselage and wind to strut attach fittings. The aft spars are equipped with wing to fuselage attach fittings, and are partial span spars.

Ailerons: Conventional hinged ailerons and single slot type flaps are attached to the trailing edge of the wings. The ailerons are constructed of a forward spar containing balance weights, formed sheet metal ribs and V type corrugated aluminum skin joined together at the trailing edge.

Flaps: The flaps are constructed basically the same as the ailerons, with the exception of the balance weights and the addition of a formed sheet metal leading edge section.

The empennage (tail assembly) consists of a conventional vertical stabilizer, rudder, horizontal stabilizer, and elevator. The vertical stabilizer consists of a spar, formed sheet metal ribs and reinforcements, a wraparound skin panel, formed leading edge skins and a dorsal.

Rudder: The rudder is constructed of a formed leading edge skin and spar with attached hinge brackets and ribs, a center spar, a wrap around skin, and a ground adjustable trim tab at the base of the trailing edge. The top of the rudder incorporates a leading edge extension which contains a balance weight.

The horizontal stabilizer is constructed of a forward and aft spar, ribs and stiffeners, center, left and right wrap around skin panels, and formed leading edge skins. The horizontal stabilizer also contains the elevator trim tab actuator.

Elevator: Construction of the elevator consists of formed leading edge skins, a forward spar, aft channels, ribs, torque tube and bellcrank, left upper and lower "V" type corrugated skins, and right upper and lower "V: type corrugated skins incorporating a trailing edge cutout for the trim tab, The elevator tip leading edge extensions incorporate balance weights.

Trim tab: The elevator trim tabs consists of a spar, rib, and upper and lower "V" type corrugated skins
