C. REASON

(1) HISTORY

Instances have been reported concerning chafing between the APU ESC (Electronic

Starter Controller) power cables (harness W205) and the tail cone firewall.

This chafing occurs because the existing grommet installed in the tail cone firewall,

intended to avoid contact between the APU ESC power cables and the tail cone

firewall, moves out of place.

This may cause damage to the APU ESC power cables.

(2) OBJECTIVE

To provide instructions to inspect the APU ESC power cables (harness W205) and

to install a new grommet support in the tail cone firewall.

(3) EXPECTED BENEFITS

This modification is aimed at keeping the grommet in the correct position to prevent

damage to the APU ESC power cables. Thus, the protection of the APU ESC power

cables will be improved as a consequence.

(4) REVISION HISTORY

REVISION 01: This revision has been issued to include new conditions related to

the inspection mentioned in this Service Bulletin.

D. DESCRIPTION

This Bulletin is divided into 2 PARTS, as follows:

PART I INSPECTION AND PROTECTION FOR HARNESS W205

Applicable to: Refer to 1.A. SB EFFECTIVITY.

PART I of this bulletin consists in performing a detailed visual inspection for damage on

the APU ESC power cables (Harness W205) and installing a support in the tail cone

firewall.

During the inspection, the criteria below should be followed :

(1) If no damage is detected to the APU ESC power cables, only a support installation

in the tail cone firewall is required;

(2) If there is any sign of damage to the APU ESC power cables, and if the damage only

affects the harness insulation, it is necessary to repair the harness insulation and to

install a support in the tail cone firewall.

(3) If there is any sign of damage to the APU ESC power cables, and if the damage

affects the harness insulation and the wire strands (inner conductors), it is necessary

to install a support in the tail cone firewall and then, replace the harness W205 as

described in PART II of this Service Bulletin.

To do this, it is necessary to gain access to the work area by removing the tail cone

access panel 351GL, and the air inlet silencer, located in zone 351.

PART II HARNESS W205 REPLACEMENT

Applicable to: Refer to 1.A. SB EFFECTIVITY.

PART II of this bulletin consists of the replacement of the APU ESC power cables

(harness W205).

To do this, it is necessary to gain access to the work area by removing the access panel

351GL, 314BR, 252AZ, the air inlet silencer, and replacing the APU power cable

feedthrough, located at zones 311 and 351.

NOTE: The modification presented in this bulletin does not affect the Fatigue

Critical Structure (FCS).

E. COMPLIANCE

1. Perform a detailed visual inspection for damage on the APU ESC power cables in the

region shown in Detail C. If necessary, pull the cable slightly in the Starter Controller

direction to help in the inspection.

NOTE: The damage may occur if the grommet installed in the tail cone firewall moves

(moved) out of its place, allowing contact between the APU ESC power cables

and the tail cone firewall.

(a) If there is no damage to the APU ESC power cables, install the new support in the

tail cone firewall. Refer to Figure 2.

(b) If there is any sign of damage to the APU ESC power cables, do as follows:

– If the damage only affects the harness insulation, repair the harness insulation

according to Figure 3 and install the new support in the tail cone firewall

according to Figure 2.

Verify if the grommet is installed in the position shown in Detail C. If the grommet

is not installed in the indicated position, reinstall it.

– If the damage affects the harness insulation and the wire strands (inner

conductors), install the new support in the tail cone firewall, refer to Figure 2 and
