overshoot, driving transients and the need for constant power lever adjustment during take-off and climb.

B. (1) (b) The current engine controls are aging, they are expensive to repair and parts are difficult to locate. (c) The current engine controls do not have the capability of automatic monitoring and recording of data necessary for engine condition trending. (2) Background: The N1 DEEC has been developed as a replacement for the original analog and digital controllers for the TFE731 engine. Using the latest circuit design and components and digital technology, this light-weight, reliable, directly interchange- able unit reduces the pilot’s workload and maintenance effort by controlling engine fan speed directly and automatically recording engine and flight parameters. Direct control on N1 allows automatic, stable thrust setting throughout takeoff, climb and cruise and eliminates “trimming” required with the previous N2 controls. Engine start logic has been improved to provide automatic enrichment, eliminating the need to utilize the cockpit SPR/Fuel Enrich switch during engine start. Increased fault detection has been added to aid in trouble shooting. The Engine Condi- tion Trend Monitoring (ECTM) software integrated into the controller automatically records all data needed to track component life, fault detection and reporting, trouble- shooting and parameter exceedance events. (3) Action: Refer to Figure 1, Service Bulletin Incorporation Flow Chart, for a process overview, and comply with the following. NOTE: The fault monitoring capability of the N1 DEEC is more capable than the older controllers. Therefore in some cases when the N1 DEEC is installed, LRU and wiring faults that were not detected by by older controllers will be de- tected by the N1 DEEC requiring the repair or replacement of LRUs or wiring. (a) Install N1 DEEC(s) as applicable in the aircraft.

D. DownLoading ECTM Data and Entering N1 DEEC/Engine Statistics NOTE: Downloading the N1 DEEC using ECTM software will erase all the N1 DEEC STORED faults. Engine condition trend monitoring is accomplished using the N1 DEEC, GSE cabling, a customer furnished personal computer, ECTM software, and for additional features, contact the JET CARE DATA MANAGEMENT FACILITY. The N1 DEEC automatically collects engine operational data and stores the information in the N1 DEEC memory. Downloading of the N1 DEEC allows customer access to raw data for typical maintenance action. Further data analysis may be provided by JET CARE. Basic features include: Recording control system faults. N1, N2 rolldown times. Exceedance peaks and duration. Engine operating and flight hours. Starts, landings, touch and go’s and landings without shutdowns for life cycle calculations. Event recording for significant events. Transfers to Manual Mode. Uncommanded engine shutdowns. Type 2 exceedances. Pilot events recorded when the pilot presses the SPR/ Fuel Enrich switch. For more events, refer to the Help File within the ECTM (Version 5.0 or subsequent revisions) software. Advanced features include: JET-CARE performance trending. Engine operational profile.

D. (1) Downloading the N1 DEEC data with ECTM software. (a) At first N1 DEEC installation and PRIOR to removal, swapping or reworking of the N1 DEEC, the N1 DEEC must be downloaded to assure data integrity. NOTE: ECTM software in the PC automatically correlates data files back to the engine serial number and historically sequences them. ECTM software will store the data files in an engine directory that is named per the serial number of the engine from which it was just removed from (in the case of an initial installation) or the engine on which it is currently located. The data file itself is named per the N1 DEEC serial number. For example: Engine SN: 91999 N1 DEEC SN: 090-AG0001 Download Count = 3 Upon ECTM data download, the following will be stored: Within the C:drive: Directory created: 91999.edr Data file created: 090-AG0001.003 NOTE: This following procedure is required only when the data downloader is first installed on the computer or the communication port settings have been changed. (b) Verify the PC communication port is set up properly using the following proce- dure. 1 Start the ECTM software by clicking the MS Windows “Start” button, then select “Programs”, the “ECTM” program group, then the “ECTM Version 5.X” program. 2 Select “CONFIGURE” on the menu bar.

G. Verify Overspeed Solenoid Operation (1) To transfer the N1 DEEC to Powered Manual Mode: (a) Apply power to the N1 DEEC. (b) Start the ECTM software by clicking the MS Windows “Start” button, then select “Programs”, then “ECTM” program group, then the “ECTM Version 5.X” program. (c) When the main menu is displayed, select the “DEEC HHT COMMUNICATION” button. (d) At the prompt (>), type ”ENG” and press “Enter”. (e) Perform required action per the following example. Displayed Action Required Setup DEEC (Y/N)? Type “Y” and press “Enter” Eng_ID: X Confirm proper ID and press “Enter” N1_Comp_Adj: X Confirm proper N1 compensation number and press “Enter” SG: X Confirm setting and press “Enter” MMSW: (AM=0, MM=1) Type a “1” and press “Enter” (2) Overspeed test. CAUTION: MANUAL MODE BATTERY STARTS ARE NOT RECOM- MENDED, BATTERY STARTS COULD RESULT IN AN OVER- TEMPERATURE AND DAMAGE THE TURBINE SECTION. NOTE: When the engine is started with powered manual mode selected, the N1 DEEC will actuate the overspeed solenoid at approximately 40-45% N2 speed momentarily. The engine will noticeably “Droop” to about 30-40% speed and recover to a normal start. (a) Perform an engine start in accordance with Aircraft Flight Manual and/or ap- propriate aircraft documents to idle with the N1 DEEC in powered manual mode. 1 If the engine exhibits the “Droop” at about 40-45% N2 speed and recovers to a normal start, the overspeed test is successful. 2 If the engine does not respond properly, first verify that powered manual mode was selected and repeat the test. 3 If manual mode was selected, perform the appropriate troubleshooting per Table 5 and the Engine Light Maintenance Manual to identify the problem component.

G. (3) To transfer the N1 DEEC to Normal Mode: (a) At the prompt (>), type ”ENG” and press “Enter”. (b) Perform required action per the following example. Displayed Action Required Setup DEEC (Y/N)? Type “Y” and press “Enter” Eng_ID: X Confirm proper ID and press “Enter” N1_Comp_Adj: 1 Confirm proper N1 compensation number and press “Enter” SG: X Confirm setting and press “Enter” MMSW: (AM=0, MM=1) Type a “0” and press “Enter” (c) Proceed to Paragraph 2.H. H. Operational Check (1) Check engine(s) acceleration. If acceleration rate/time differs, and requires adjustment, the SG setting may be moved up or down as follows. NOTE: Raising SG will decrease (shorten) engine acceleration time. Lowering SG will increase (lengthen) engine acceleration time. Excessive upward adjustment is undesirable since it may result in engine compressor instability (surge) during rapid power lever advance. Excessive adjustment in the downward direction is also undesirable in that it may reduce engine acceleration capability to an undesirable extent and may result in lean blowout. To compensate for individual engine characteristics or installation effects, a typical variation in acceleration adjustment setting (SG) may be to decrease by one value (setting number), or increase by two values (setting number), however, adjustments are not limited to these values and may be increased or decreased as necessary. (a) Apply power to the N1 DEEC. (b) Start the ECTM software by clicking the MS Windows “Start” button, then select “Programs”, then “ECTM” program group, then the “ECTM Version 5.X” program. (c) When the main menu is displayed, select the “DEEC HHT COMMUNICATION” button. (d) At the prompt (>), type ”ENG” and press “Enter”.
