In order to avoid that transitorymessages are displayed during thepower up, a 120-second-delay was

implemented to the logic o someEICAS messages.

Prior to this logic modiication, alist o 17 messages were inhibitedduring power up in several Epic

Flight Control No Dispatch Best Practices Service News Letter (SNL)

Embraer developed the SNL170-27-0061 and SNL190-27-0057 that bring

a compilation o the best practices with

the purpose o helping the operators

to troubleshoot the Flight Controls No

Dispatch (FCND) ailures. These practices

have been identiied during FCND Tiger

Team meetings and were complemented

with good maintenance practices shared

by operators over the time.

The document is divided in sections thatconsist o, among others, troubleshooting

tips, reset guidelines, health monitoring

basics and a list o FIM tasks that were

revised due to Tiger Team workshop.

These practices have proved to be helpul or

operators to identiy and reduce repeaters

aircraf, speed up troubleshooting, build a

conident database with FCND ailures that

helps troubleshooters on similar situationswith the purpose o dropping FCND ailure

rate (delays and cancellations).

Furthermore, the FCND Tiger Team hasstudied the perormance o several

operators with low and high FCND

rates and has determined a correlation

between reset and FCND ailure rate.

The autobrake system provides automaticbraking at maximum deceleration rates. It

controls hydraulic pressure to the brakes

and provides a constant deceleration rate.

Four autobrake levels (LO, MED, HI and

RTO) are available via a selector knob on

the cockpit main instrument panel. The

aural message AUTOBRAKE is enabled

when the selected level is disarmed by the

autobrake module (ABM) or brake control

module (BCM) ailure during parking,

taxiing, takeoff roll or landing.

No More Auto Brake SpuriousWarnings on Load 25.1

Every autobrake system ailure is displayedon the EICAS through the AUTOBRAKE FAIL

message. However, Embraer customers have

reported spurious auto brake aural warning

during take-off, which increases the pilot

workload.

Afer investigating this issue, ABM PN 142-

071171was introduced in 2008 as an interim

action to address 70% o the events. The

inal solution was released in 2011 through

Honeywell load version 25.1. Two years afer

the implementation, the effectivenessanalysis showed no pilot reports o

spurious auto brake aural warning during

take-off and the solution was considered

effective.

Reminder

Victor de Andrade Nunes


[email protected]

As inormed in the Technical Workshop during theEOC Rio 2013, corrupted DPRAM data in one FADECchannel could initiate uel shutoff request, causingengine shutdown.

FADEC V5.42 sofware brings a modiied DPRAMdata corruption ault logic and thrust controlmalunction (TCM) shutdown logic, so that crosschannel shall no longer command uel shutoff inthe standby channel.

Did you know?

There are some cases where a good pictureworths more than a thousand words and

more than the need to understand hard

technical drawings.

This Service Newsletter which is an Embraer

ormal document, was irst presented as a

draf to some operators and those rapidly

requested Embraer to make it official by

means o a SNL.

Figure 1 Check o ODS wire or proper installation

The new SNL 190-36-0022 aims toprovide some important tips to support

the maintenance personnel during the

incorporation o Embraer SB 190-36-0019 -

PYLON - OVERHEAT DETECTOR SENSORS

(ODS) INSTALLATION IMPROVEMENT.

The aorementioned mentioned document

is available at FlyEmbraer since the

beginning o Dec/2013.

MRB process achievements in 2013

In this edition the Focus Onhas the main goal to dividewith the readers the excellentresults reached during theE-Jets MRB process over 2013.Trough established partnershipwith Airlines to send and/orauthorization o inormationacquisition arising rom thescheduled maintenanceinspections, participation andvalidation o technical proposalduring Working Groups, it waspossible the progress o E-JetsEscalation Project and publishingo Temporary Revision aiming

to make easy the scheduledmaintenance and consequently,reducing cost.

Technical Proposal or E-Jets

MRB Optimization

Altogether were presented more than 500

technical proposals addressing the interval

optimization o the Basic 1 maintenancepackage rom 6,000 FH to 7,500 FH and Basic

2 rom 12,000 FH to 15,000 FH where it was

considered system section, structural and

zonal tasks. Other tasks were addressed

and through the data collected rom ield

with the reliability analysis was possible

to get an approval with ANAC (Primary

Authority) and authorities (FAA/EAS/TCCA)

temporary revision to rise complex tasks

intervals as Horizontal Stabilizer Backlash,

inspection o control cables in uselagearea and other tasks that presented high

accomplishment cost.

Another important point to be considered

to 2013 was the presentation o more

than 10,000 pages o technical subsidies

related to statistical and reliability analysis

to determine the new interval 25% higher

than the actual one or the deinition

o optimal interval based on ield data

analysis (scheduled and non scheduled

maintenance).

In summary, we had over this year, meetingo optimizing structures / zonal, twogeneral optimization meetings, whereit was discussed proposals or systems,structures, zonal and ISC (Industry SteeringCommittee) in early November where alltechnical proposals that were approved bythe Working Groups had a second approvaland will be submitted or inal approvalby the authorities in the event calledMRB meeting, which will take place in theweek o 20th to 24th January 2014 andwill involve the authorities and operatorsrepresentatives(ISC and WG Co-chairman).Other two technical events and ISC realizedduring 2012 (Structural / Zonal WorkingGroups and General Working Group) hadtechnical proposals approved and will besubmitted to MRB meeting in January 2014.

As additional results we had had approvals

by the technical Working Group and ISC o

rising interval to some tasks rom the INT

package that stayed out o phase afer the

irst part o the optimization project o this

package during 2010 and 2011.

Achieved Results during 2013

The ollowing results were achieved during

the Working Groups and approved in the

ISC meeting perormed in 2012 and 7th

and 8th o November 2013 and will be

submitted to authorities approval.


As shown in the graphics below,the next MRB 170/175 revision(rev 9) and MRB 190/195 (rev7) will bring partial resultson E-Jets escalation projectsBasic 1 as to Basic 2 foreseento April 2014.

It is important to highlight the result obtained

with the evolution o structural program

and CPCP in 2013 where harmonization

between 170 and 190 programs and

the deinition o optimal intervals were

discussed and agreed in the Working

Groups ensuring continued airworthiness

with low maintenance costs. It is hoped,

through the new structural program which

will be partially available in April 2014, that

E-Jets operators realize how much the plan

is improved. However, completion o BASIC

1 project and also the review o structures

will occur until mid-2014.

Next Steps in 2014

The next year, will be no different o 2013 and will have great

challenges both rom the point o view o continuity o ield

data collection as the participation o business areas or the

validation and approval o technical proposals to complete

the escalation o BASIC 1 in June 2014, and BASIC 2 in

December 2014.

It is planned or the middle o next year to issue a temporary

revision addressing technical proposals approved during the

Working Groups and ISC in the irst hal o 2014 and another

ull review o MRB 170/175 (rev 10) and MRB 190/195 (rev 8)

contemplating the escalation intervals BASIC 2 in January

2014.

We would like to thank all operators and authorities that

have participated in this milestone providing the E-Jets with

optimized intervals and seize the opportunity to wish you allhappy holidays and a great new year ull o happiness and

achievements.

Last November, British Airways decorated one of their E-190s with a giant moustache. This is a joint action with London City Airportto support the charity campaign called Movember. Movember (a merged word of mustache and november) is an annual, month-longevent that encourages men to grow their moustaches as a way of raising the awareness of prostate cancer and other male cancer andassociated charities. Passengers could take photographs of the giant moustache in exchange of a donation. Passengers were also invi-ted to share photos and their own Movember efforts online, with prizes available to thank them for their donation. The results are great.

In 2012, British Airways raised 80,000 worldwide for the Movember campaign. Source: BA Cityflyer
