Quickie Q2 Lite, Construction Manual

AMATEUR-BUILT Q2 INSPECTION CRITERIA
1.0 SCOPE
..... This document has been prepared to assist inspection personnel
by providing recommended acceptance criteria and acceptable repair
practices for the Q2 amateur-built composite sandwich structure.
2.0 BACKGROUND INFORMATION
2.1 DESIGN CRITERIA
..... The materials, methods, and practices employed by the amateur
builder in the construction of the Q2 type are new to light aircraft
construction and may be unfamiliar to the inspection personnel
involved with the licensing of amateur built aircraft. Structural
design criteria for the Q2 exceed F.A.R. part 23 requirements. In-
house component testing of the primary flight structure has been
conducted to 200% of design limits. Detail documentation of test data
is on file at Quickie Aircraft Corporation. The aircraft is
considered to be a utility category aircraft. Q2 builders are being
supplied with a complete owner's manual which specifies all placards,
operating limitations, normal and emergency operations, flying
qualities, maintenance specifications, inspection procedures, and
initial flight test procedures.
2.2 STRUCTURAL APPROACH
..... The basic structure throughout the design is a composite
sandwich of load bearing fiberglass skins separated by a light-weight
foam core. While the materials and processes are tailored to the
amateur builder, the structural layout is very similar to the
honeycomb composite structures stylized in military and transport
type aircraft and fiberglass sailplanes. Loads are carried by epoxy
jell-type fiberglass lamina. Foams of various types and densities are
employed as a form (upon which the load bearing material is shaped)
and as local buckling support. In no instance are foams used to
transmit primary loads, as is the case in some other amateur-built
designs.
2.3 INSPECTION TECHNIQUES
..... The transparent nature of the fiberglass/epoxy material allows
for visual inspection of primary structure from the outside prior to
finishing. Defects in the structure, as described in paragraph 3.0,
are readily visible even in the deepest laminate.
