Structural Repairs; Baggage Compartment Inspection Hole And Cover Plate - Piper Dakota Maintenance Manual

GENERAL
DESCRIPTION
The PA-28-236 is an all metal semi-monocoque structure. The fuselage is constructed of bulkheads,
stringers and stiffeners, to which the skin is riveted. The cabin entrance door is located on the right side of the
fuselage above the wing. The wings and empennage are full cantilever semi-monocoque type construction with
removable thermoplastic tips.

STRUCTURAL REPAIRS

Structural repairs must be made in accordance with the regulations set forth in FAA Advisory Circular 43-
13-lA. To assist in making repairs or replacements, figure 51-1 identifies the type and thickness of various skin
materials used.
No access holes are permitted in any control surfaces. The use of
patch plates or repairs of all movable tail surfaces is prohibited.
The use of any filler material normally used for repair of minor
dents and materials used for filling the inside of surfaces is also
prohibited on all movable tail surfaces.
Never make a skin replacement or patch plate from materials other than the type used on original skin. The
repair must be as strong as the original skin and flexibility must be retained so the surrounding areas will not
receive extra stress.

BAGGAGE COMPARTMENT INSPECTION HOLE AND COVER PLATE.

(See latest revision of Piper Service Bulletin 977.)
a. General.
Airplanes manufactured before 1979 may not have had control cable inspection access holes in the
baggage compartment floor. The following is a method of fabricating inspection access holes in the floor of
the baggage compartment, if desired.
b . Baggage Compartment Inspection Holes Fabrication Procedure. (Refer to Figure 51-1a.)
While Figure 51-1a shows the hole in the left side of the baggage compartment, a similar hole is
also cut out in the right side baggage compartment floor. Installation will require two each inspection
access covers, Piper P/N 62109-00.
1. Layout cut lines
