Access Panel Identification
Refer to Figure 1 for identification of access panels.
Generally all access panels
(and fairings) are screwed on the respective
structure or surface. However for the access to the oil filler and the external
power receptacle hatches are used featuring a hinge and a latching mechanism.
The LH wing nose access panel carries the stall sensor. So refer to Chapter 34-
10-13 for removal.
To get access to the passenger compartment floor access panels the carpet has
to be removed.
To get access to the central horizontal stabilizer access panel the fin tip has to
be removed (refer to Chapter 55-30-01).

INVESTIGATION
51-10-01
Damage Classification
All damage of composite parts must first be classified by qualified
WARNING
personnel. In case of doubt regarding the classification of damage, if a
clear definition of the extent of damage is not possible, or if a repair of
damage despite the consideration of the valid manufacturer
documentation is doubtful, contact EXTRA.
Only the Damages Classes 2, 3 and 4 may be repaired by qualified
WARNING
personnel. In case of Damage Class 1 EXTRA has to be contacted.
Following to the Luftfahrt Bundesamt (Federal German Aviation Authority)
four damage classes are defined:
Damage Class 1:
Large scale destruction requires a partial reconstruction of the component or
large scale repair. Each destruction over 300 mm diameter and each damage of
a spar or the pressure cabin is a “large scale destruction”. EXTRA has to be
contacted prior to repair.
Damage Class 2:
Damage to primary structures and to secondary structures to the following
extent: Holes and fractures extending through a sandwich component and a
scale under 300 mm diameter.
Damage Class 3:
Damage to primary structures and to secondary structures to the following
extent: Small holes or fractures in the external covering layers, if not
accompanied by damage to supporting layers or internal covering layers.
Damage Class 4:
Erosion, scratches or nicks not accompanied by fractures or break-ups. Damage
to fairings belong to this class.

51-10-02Repair Criteria and Limits
IMPORTANT
Any damage of composite parts must first be classified prior to repair.
Refer to Subject 51-10-01 Damage Classification.
IMPORTANT
Only the Damages Classes 2, 3 and 4 may be repaired by qualified
personnel. In case of Damage Class 1 EXTRA has to be contacted.
The decision whether to repair or replace a major unit of structure will be
influenced by factors such as time and labor available, and by comparison of
labor costs with the price of replacement assemblies. Past experiences indicate
that replacement, in many cases, is less expensive than major repair. Certainly,
when the aircraft must be restored to its airworthy condition within limited
time, replacement is preferable.

MATERIALS
This Section describes metallic and non-metallic materials used in repairing the
EXTRA 500 and gives the sources of supply (manufacturers and suppliers).
IMPORTANT
Only approved materials have to be used for repair.
Materials not listed here are generally used for parts, which are not intended for
repair. Contact EXTRA for advice.
Observe the data and safety sheets when working with auxiliary materials such
as sealants, adhesives, solvents, agents and the like. However, if not stated
otherwise, aircraft parts must not be heated to more than 80 °C (176 °F) for
example in curing processes.

CONTROL SURFACE BALANCING
51-60-01
Weighing and Determination of
Control Surface Moments
Weighing and determination of control surface moments is necessary after
repairs or painting. All weighing of control surfaces is performed with surfaces
removed from aircraft. Weigh the control surfaces including mass balances and
brackets but without control rods.
The RH elevator weight includes the trim tab installed and provisionally held
in elevator surface plane by means of tape (see also Figure 51-3).
Copy Figure 51-4, enter the values (W, m, r) and check whether the surface
weights and moments are within the given tolerances. If they are not, contact
the EXTRA for advice.
For the determination of control surface moments follow the steps as described
below and use two balancing mandrels like shown in the Figure 51-2:

Detail Steps/Work Items
Key Items
1
Remove the control surface.
Refer to Chapter 27
2
Reinstall the bolts in the brackets where
Aileron inboard hinge
applicable.
Elevator outboard hinge
3
When weighing RH elevator fix trim tab
with tape.
4
Put the control surface on the balancing
Refer to Figure 51-3
mandrels (use a wire for the trim tab).
5
Level control surfaces and weigh by means
Refer to Figure 51-3
of a conventional spring balance (kg/g-
indication) at the given weighing points and
enter the weight (m) in figure 4.
6
Measure distance of hinge center line to
weighing point (r) and enter the value in
Figure 51-4.
7
Calculate the control surface moment (M) in
Figure 51-4.
IMPORTANT
If values exceed the given tolerances in Figure 51-4 contact EXTRA
before modifying of control surfaces.
8
If necessary modify control surface under
EXTRA’s guidance.
9
Reinstall the control surfaces.
