1. PLANNING INFORMATION

A. EFFECTIVITY

This Service Bulletin is applicable to FALCON 7X aircraft with serial numbers 4, 5, 6, 7, 10, 12, 15, 16,

20, 22, 24, 25, 26, 29, 30, 32, 33, 35, 36, 38, 40, 41, 43, 44, 46, 51, 52, 56 and 63 which are equipped

with the following equipment:

• LH PDCU A (L301PM) part number (P/N) 80232190,

• RH PDCU A (R301PM) P/N 80232190,

• LH PDCU B (L401PM) P/N 80232191,

• RH PDCU B (R401PM) P/N 80232191,

• engine 1 GCU (5500PC) P/N 80232192,

• engine 3 GCU (6500PC) P/N 80232192,

• APU starter GCU (303PC) P/N 80232192.

B. REASON

Some cases of RH essential bus disconnection from the RH main bus, with the "ELEC: RH MAIN

FAULT" CAS message, have been reported on in-service aircraft.

The investigation revealed that this disconnections were caused by an overcurrent detection, due to a

defective component, called transient voltage suppression diodes, located on PDCU and GCU cards.

The purpose of this Service Bulletin is to inspect the PDCU and GCU cards in order to replace the defective

ones.

C. DESCRIPTION

The operation consists in:

• removing the PDCU and GCU cards,

• checking the cards (this operation must be performed by a GOODRICH representative),

• replacing the defective cards.

D. COMPLIANCE

Mandatory:

• It is anticipated that this Service Bulletin will be rendered mandatory by an EASA Airworthiness

Directive.

• As prescribed by the Airworthiness Authorities of the country of registration of the aircraft.

E. APPROVAL

The technical content of this document is approved under the authority of DOA nr. EASA.21J.051.

(5) Push the "TEST" button on the test-set, make sure the 40 RED LEDs illuminate.

NOTE: If, the RED LEDs do not illuminate the test set is damaged.

B. Procedure

(1) Plug the board into the PDCU A connector on the test-set (Ref. Fig. 1).

NOTE: The top side of the board (the side with the main connector) must face you.

(2) Connect a ground lead to the socket "GROUND" on the test-set. Use a crocodile clip and connect

the ground lead to the thermal plane of the PDCU A card (Ref. Fig. 2).

(3) Record serial number of the PDCU A card and the test-set on the Results sheet.

(4) Push the "TEST" button on the test-set, record the status of all the LEDs on the Result Sheet

Appendix 1.

NOTE: This is to collect data for possible future enhancements.

(5) Release the test button.

(6) Push the "TEST" button on the test-set, and make sure the circuit LEDs listed (Ref. Table 1) are all

GREEN.

A. General

CAUTION: THE SPDB CONTAINS ITEMS THAT ARE ELECTROSTATIC-DISCHARGE SENSITIVE

(ESDS). OBEY APPROVED INDUSTRY PRECAUTIONS WHEN YOU TOUCH, REMOVE

OR INSTALL PARTS. DAMAGE CAN OCCUR FROM ELECTROSTATIC DISCHARGE.

NOTE: This SB is intended for use on a PDCU B that is removed from the PPDB and off the aircraft.

(1) Place the PDCU B card on the ESD mat.

(2) Connect a ground lead to the ground socket of the test-set and a suitable earth point.

(3) Connect the DC plug from the Power Supply Unit (PSU) to the 48 volts socket on the side of the

test-set.

(4) Connect mains lead from the PSU to an applicable a.c. outlet and apply mains power.

(5) Push the "TEST" button on the test-set, make sure the 40 RED LEDs illuminate.

NOTE: If, the RED LEDs do not illuminate the test set is damaged.

B. Procedure

(1) Plug the board into the PDCU B connector on the test-set (Ref. Fig. 1).

NOTE: The top side of the board (the side with the main connector) must face you.

(2) Connect a ground lead to the socket "GROUND" on the test-set. Use a crocodile clip and connect

the ground lead to the thermal plane of the PDCU B card (Ref. Fig. 2).

(3) Record serial number of the PDCU B card and the test-set on the Results sheet.

(4) Push the "TEST" button on the test-set, record the status of all the LEDs on the Result Sheet

Appendix 1.

NOTE: This is to collect data for possible future enhancements.

(5) Release the test button.

(6) Push the "TEST" button on the test-set, and make sure the circuit LEDs listed (Ref. Table 1) are all

GREEN.
