Презентация на тему Things “Not-to-do”. These procedures are suitable for primus epic load 21

TO
EMBRAER 170 / 190 EQUIPPED WITH PRIMUS EPIC

LOAD 21 AND SHOULD BE USED FOR TRAINING PURPOSES ONLY

THE PURPOSE OF THIS GUIDE IS TO AWARE FLIGHT CREW AND MAINTENANCE STAFF ABOUT THE MOST COMMON REPORTED RAMP MISTAKES

ALWAYS REFER TO THE APPLICABLE MANUALS BEFORE PERFORM MAINTENANCE TASKS.

Note: This is important to avoid that the EICAS messages
and come into view right after the PBIT finish.

DO

NOT: open any AMS SSPCs before any AC source on buses. (GPU/APU/IDG on line)

ELECTRICAL SYSTEM (CONT.)

4

NOT: set the external STEERING switch to ENGAGE position

before disconnect the towbar assy from NLG.
Note 1: It could lead the STEER system to a “fail-safe” mode, and the STEER FAIL appears on the EICAS display.
Note 2: A power reset is necessary to clear the message
RIGHT PROCEDURE: Remove the towbar from the NLG, THEN set the STEERING switch to ENGAGE position.

AGAIN if:
After the complete power up procedure, the AC

buses were de-energized for more than 10s. For instance, in case of a failure on the GPU or APU GEN. Scenario: Batt #1 ON, Batt #2 AUTO and AC power off bus.
Note: With only ESS power available, FCMs lanes B are OFF, and in this case, when hydraulic power is set to ON, a message FLT CTRL NO DISPATCH will be displayed on EICAS.

USE before perform the batteries voltage check. (ALWAYS FOLLOW

THE POWER UP PROCEDURES)
Note 1: Wait at least 10s between batteries ON and GPU IN USE.
Note 2: This always inhibits the flight controls Power-up Built-In Test (P-BIT). If the P-BIT does not run, the message FLT CTRL NO DISPATCH will be displayed.

deflected while the associated hydraulic systems (#1 and #3)

are depressurized.
Note 1: Doing that, a message FLT CTRL NO DISPATCH may be presented on EICAS display. An associated maintenance message RUDDER PERFORMANCE FAULT (fault code 27030553FCS) may be displayed on CMC active faults.
Note 2: In order to avoid this scenario, make sure that the YAW TRIM (confirm on EICAS display) is neutral before pressurize the hydraulic systems.

Note 1: Doing that, a message PITCH TRIM

SW 1 FAIL / PITCH TRIM SW 2 FAIL or PITCH TRIM BKUP FAIL will be presented on EICAS display.

Note 2: To clear these messages it is necessary to cycle both Cut-Out switches.

APU indications complete 100% (APU GEN supplying AC network)

Note

1: Doing that, a message FLT CTRL NO DISPATCH will be presented on EICAS display when hydraulic power is set to ON.
Note 2: To clear these messages it’s necessary to cycle Flight Control Mode Panel pushbuttons.

2 OFF.

Note 1: Doing that the multi-function spoiler panels may not fully stow, causing a disagreement between the control wheel position and the surface position. If the aircraft is powered down and powered up with any disagreement the message SPOILER FAULT will be presented on EICAS display.

Note 2: To clear the SPOILER FAULT message it is necessary to turn “ON” the hydraulic systems 1 and 2.

turn hydraulic pumps OFF to speed up the hydraulic

systems depressurization.
Doing that, the CMC message RUDDER PERFORMANCE FAULT may be presented and it triggers the FLT CTRL NO DISPATCH message on EICAS display.
To clear the EICAS message, it’s necessary to perform the Return-to-Service test.

Doing that,

the CMC message RUDDER PERFORMANCE FAULT may be presented and it triggers the FLT CTRL NO DISPATCH message on EICAS display.
