GENERAL.
DESCRIPTION .
The PA-44 is an all metal semi-monocoque structure. The fuselage is constructed of bulkheads, stringers
and stiffeners, to which all of the outer skin is riveted. The cabin entrance door is located on the right side of
the fuselage above the wing. An emergency exit is provided on the left side of the fuselage, and consists of the
pilot's side window and surrounding window frame. The wings and empennage are all metal, full cantilever
semi-monocoque type construction with removable tips.

Structural repair methods used must be made in accordance with the regulations set forth in FAA Advisory
Circular 43-13-1A. To assist in making repairs and/or replacements, Figure 51-1 identifies the type and
t h i c kness of various skin material used.

must be retained so the surrounding areas will not receive extra stress.
