Type V Hydraulic Fluid Certification

Embraer has taken the decision not to pursue to the approval of Type V Hydraulic Fluid for the E-Jets fleet.

The main reason is the high cost and the high demand of engineering resources involved in, only for compat-ibility verification between the new fluid and the air-craft current components. There are no guarantees that extensive product modification would not be nec-essary. This analysis certainly would require dedicated tests for each of the components from the various sup-pliers involved, once an eventual incompatibility could cause degradation or any other unexpected behavior, impairing the normal operation of the aircraft systems.

Whereas there is no indication that the current type of fluid used in the E-Jets will be discontinued and no relevant performance improvement has being ev-idenced, Embraer has decided not to pursue to the approval of Type V Hydraulic Fluid for the E-Jets fleet now.

This question may be resumed if the Type IV Hydraulic fluid goes into an obsolescence process.

EPIC LOAD

A new EPIC Load, gives a great opportunity to update the fleet, with new functionalities, or acti-vate them. From the operational standpoint, fixes and improvements contribute to minimize opera-tional impacts and crew workload.

The airline maintenance crew is also the focus of a load release since fixes and improvements contrib-ute to a more effective troubleshooting, minimizing workload, aircraft downtime and parts availability.

The E-Jets Avionics System has a highly integrated architecture, which consists of cockpit controls and displays, communication systems, sensors and actu-ators.

Many control functions which were usually hosted in single line replaceable units (LRUs) in previous gen-eration architectures are currently integrated into the

modular avionics unit (MAU) and the modular radio cabinets (MRC) of the E-Jets Primus Epic System, which is software-based controlled.

EMBRAER and suppliers, concerned with aircraft dispatch reliability and operation, are always work-ing towards providing to the customers fixes and improvements for deviations detected during air-craft operation, test campaigns and new function-alities.

The most recent fixes and new functionalities are available in the new EPIC LOAD versions. Load 25.3 for aircraft equipped with Pentium II configuration and Load 25.4 for aircraft equipped with Pentium M configuration.

It is important to remind that EPIC Load is a Single Line of Software delivery, meaning that the same software CD may be installed in both EMBRAER 170 and EMBRAER 190 aircraft families.

Embraer encourages the operator to plan the instal-lation of the subjected new Epic Load versions in their fleets for getting benefits of the last fixes.

In the next paragraphs main changes highlights will be described.

EPIC LOAD 25.4

Primus Epic Load 25.4, for Pentium M, released on October, 2012 brings some new functionalities, im-provements and fixes.

Regarding new functionalities the ADS-B OUT (ac-cording DO-260B), Data Link Recording and CPDLC were implemented in order to accomplish the Eu-ropean Mandates. These functionalities can be en-abled by incorporating dedicated Embraer Service Bulletins which commercial conditions are provid-ed by the account team.

Changes introduced by Load 25 made possible the inclusion of the FLT CTRL FAULT EICAS message on the Master Minimum Equipment List MMEL. After the MMEL approval, for aircraft with Primus EPIC Load 25.4, it will be possible to dispatch it with FLT CTRL FAULT displayed (repair interval is within 2 calendar days). This MMEL revision will improve the aircraft dispatch reliability by significantly reduc-ing flight delays and cancellations due to FLT CTRL FAULT.

It is important to bring to your attention that Load 25 must be installed before upgrading the cur-rent E170/175 HS-ACE to new PN 415300-1005 (SB 170-27-0046). HS-ACE is one of the main offenders for FLT CTRL NO DISPATCH and new HS-ACE PN 415300-1005 is aimed at reducing over 60% of flight interruptions (FCND) due to HS-ACE.

Still, Epic Load 25.4 (and also 25.3) implements a modification that increases the robustness of the Aileron Primary and Secondary Input Voltage Mon-itors, contributing to the decrease of FLT CTRL NO DISPATCH messages.

Moreover, before Load 25.4, the procedures called Circling Approach (characterized by the procedures that do not have the runway defined on the charts) were inhibited, and with this Load, the subject-ed procedures will be available, allowing pilots to choose flying the instrument part of this kind of pro-cedure using the FMS.

EPIC Load 25.3

Primus Epic Load 25.3 (for Pentium II) brings all the fixes, improvements and new functionalities imple-mented on Load 25.1.0.1, Load 25.2 and 25.4, except for the CPDLC that is not compatible with the Penti-um II modules.

One of the more relevant items, considering pilots point of view, is the improvement on the VNAV log-ic during all lateral transitions or altitude constraints modifications when in PTH mode, avoiding incorrect path capture during FMS recalculations.

For fleets with Pentium II configuration, the chang-ing from Load 21.4 or 23.1 to 25.3 is the terminating action for the following Operational Bulletins:

170-006/09: FMS position anomaly;

170-001/10: FMS misbehavior upon runway change when no arrival or approach procedure is selected;

170-004/10: Anticipated top of descent when two AT altitude constraints are at the same altitude/flight level;

170-001/11: FMS anomaly in terminal area proce-dures, using heading legs displayed as FLY XXX OR AS ASSIGNED (Figure 1); Figure 1 (Illustration Only)

170-002/11: Primus epic FMS software - arc melding issue;

170-004/11: Reduction of navigation database pro-cedures content due to; possible FMS lateral naviga-tion (LNAV) display/guidance issue (Figure 2);

170-002/13: FMS turn misbehavior due to incorrect leg sequencing.

Provision for improvement in the Oil Pressure Indi-cation System (Figure 3) is also present in the new Load. In the past, EMBRAER received reports of com-manded engine in-flight shutdown events in the field associated with a false indication of engine oil low pressure. In these cases, troubleshooting showed

that there was no real loss of pressure, but rather an indication issue, mostly associated with a faulty oil pressure transmitter (OPT). As per the E-Jets News Edition 77 (May, 2013), GE has already released SBs (GE SB 77-0005 for CF34-10E and GE SB 77-0007 for CF34-8E), to mitigate these events by introducing im-proved OPTs (P/N 4120T16P02), more robust to ele-vated temperatures.

In addition to that, EMBRAER and GE are also work-ing on the re-introduction / re-activation of the low oil pressure switch (LOPS) as a redundancy to the OPT, thus increasing the ability of the system to de-tect indication-related faults. Version 25.3 EPIC Load Software brings logic provisions for the LOPS signal to be interpreted by the aircraft when the complete system is installed.

The incorporation of this EPIC Load Software is in-dependent from the re-activation of the LOPS. The latter will only be activated if the switch / harnesses are installed, FADEC Software 8Ev5.60 / 10Ev5.50 is incorporated and the FADEC ECP is reprogrammed (which are expected to be released to the field in the 2Q/2014).

Regarding the FADEC Fan Cooling System for the EMBRAER 190/195 aircraft, as part of the on-going actions to increase the CF34-10E FADEC reliability in the field, Embraer and GE are developing an active Fan Cooling System to better control the thermal en-vironment that the FADEC is subject to. This is aligned

Figure 2 (Illustration Only)

with the root cause investigation, which revealed that the FADEC reliability is primarily driven by, the: a) Del-ta Temperature between on-ground and in-flight op-eration and b) Maximum temperature on the ground.

Version 25.3 EPIC Load Software brings the logic pro-visions necessary for the Fan Cooling System to work. When installed together with other components of the system (Fan Hardware, Harnesses, FADEC Soft-ware 10Ev5.50, SPDA Software Block 12), planned to be released in the 2Q/2014, it will allow the system to be activated. It is important to highlight that the incorporation of this EPIC Load Software is indepen-dent from the FADEC Fan Cooling System. The latter will only be activated if the complete system is in-stalled and the FADEC ECP is reprogrammed.
