The serial range provided above is the elevator serial number , not the airplane serial number

. The information can

be found on the pla card on the elevator itself

. The placard is located on the front face of the spar at the trim actuator
pass through hole.

This Field Service In struction provides procedures for installation of a doubler at the inboard forward corner of each

elevator trail ing edge skin , top and bottom.

AFFECTED MANUALS AND PUBLICATIONS

None

WEIGHT AND BALANCE

The weight and balance changes to the elevator have been evaluated and found to be negligible; the elevator does not

need to be weighed and balanced after complying with this Field Service Instruction. If the mechanic chooses to perform
work outside of the scope and instructions provided within this document, the mechanic must reference the current

revision of the AM902.0 KODIAK ® 1 00 Airplane Maintenance Manual , for instructions on weighing and balancing the

elevator control surface

.

MANPOWER

The estimated man

- hours and minimum number of persons required to perform this Field Service Instruction are listed

below. The “Minimum Perso ns” refers only to maintenance personnel or installers, and unless otherwise specified
within this instruction does not include additional personnel that may be needed solely to comply with safety
requirements (for example, safety observers that are not pe rforming tasks within this instruction). It is the responsibility
of maintenance personnel to comply with saf ety requirements, including having a safety observer available as needed.

Estimated Man

### 3. General

This Field Service Instruction provides procedures for inspecting for cracking of the inboard
upper and lower skins of the elevator and installation of doubler s to repair existing cracking or
prevent cracks from occurring

.

N N O O T T E E

Inspect a total of four locations on the airplane and perform repairs/install doublers at each in accordance with the

instructions in Section 4.0 and Section 5.0

.

N N O O T T E E

All dimensions throughout this document are in inches

. Unless otherwise noted, dimensions with one decimal

place, X.X, are ±0.100 and those with two decimal places, X.XX, are ±0.030.



### 4. Preparation

1. Remove the tailcone in accordance with AM902.0, KODIAK 100 Airplane Maintenance

Manual

, Chapter 53, Fuselage.

The elevator may be removed to provide better access to the inspection and repair area

.



### 2. Inspect the elevator, both top and bottom, for signs of cracking in the forward inboard

end of the trailing edge skin, aft of the spar ( Figure 4

- 1 ) by using the following
procedure based on AC43.13

- 1B, Section 2 :

a. Provide adequate lighting to illuminate the edges of the elevator trailing edge skin.
