Overview
This Service Bulletin (SEB-34-21) addresses a software update for the G1000 NXI navigation system in Cessna aircraft, specifically targeting the T206H and 182T models. The update modifies the Electronic Stability Protection (ESP) system to prevent autopilot engagement at low airspeeds, which can be critical during training maneuvers. The bulletin provides detailed instructions for mechanics on how to implement the software update, including compliance recommendations and necessary precautions to avoid system failures during the update process. It emphasizes the importance of following the outlined procedures to ensure the aircraft's avionics operate correctly and safely after the update.
- The service bulletin applies to Cessna T206H and 182T models with specific serial numbers.
- Compliance is recommended during the next 100-hour or 12-month inspection.
- The software update prevents autopilot engagement at low airspeeds.
- Detailed step-by-step instructions are provided for the software update process.
- Final checks must confirm that all systems are functioning correctly after the update.

Single Engine SERVICE BULLETIN SEB-34-21 TITLE NAVIGATION - G1000 NXI WITH ESP SOFTWARE UPDATE TO VERSION 2501.10 THAT TURNS OFF THE AUTOPILOT ENGAGEMENT AT LOW AIRSPEED EFFECTIVITY Airplanes that follow that have 2501.03 thru 2501.09 software installed. MODEL SERIAL NUMBERS 182T 18283062 thru 18283101 T206H T20609560 thru T2069603 The equivalent of this service document has been incorporated on production airplanes 182T: 18283102 and On, T206H: T2069604 and On. REASON The Electronic Stability Protection (ESP) will command a nose down pitch when the aircraft is in-air and at an angle of attack to trigger movement of the stall warning vane. If ESP remains engaged for 10 seconds (non-consecutive) in a 20 second interval, the system will engage the Autopilot (AFCS) in LVL-LVL mode, which then enables automatic pitch trim authority. This can be unexpected when intentionally operating the airplane in some flight conditions such as during training flights with slow flight maneuvers or power off stalls. DESCRIPTION This service document provides parts and instructions to update the software which prevents the system from engaging AFCS and automatic pitch trim resulting from an ESP Low Airspeed Protection command. Low Airspeed Protection remains enabled but will not engage the autopilot. Other ESP triggers such as exceeding pitch and roll limits will still engage the autopilot in LVL-LVL mode and remain unchanged. The procedures required to enable or disable ESP remain unchanged. COMPLIANCE RECOMMENDED. This service document should be accomplished at the next 100-hour or 12-month (annual-type) inspection. A service document published by Textron Aviation may be recorded as completed in an aircraft log only when the following requirements are satisfied: 1) The mechanic must complete all of the instructions in the service document, including the intent therein. 2) The mechanic must correctly use and install all applicable parts supplied with the service document kit. Only with written authorization from Textron Aviation can substitute parts or rebuilt parts be used to replace new parts. 3) The mechanic or airplane owner must use the technical data in the service document only as approved and published. 4) The mechanic or airplane owner must apply the information in the service document only to aircraft serial numbers identified in the Effectivity section of the document. 5) The mechanic or airplane owner must use maintenance practices that are identified as acceptable standard practices in the aviation industry and governmental regulations.

CAUTION: Do not rely on the aircraft battery to load software. Do not use a battery charger as an external power source due to electrical noise it may inject in the G1000 system. Power loss during a software upgrade may cause a lru to become corrupted and unresponsive requiring replacement. Remove power only when told to do so in the procedure. NOTE 1: If the system software or configuration fails to upload correctly during accomplishment of this Service Bulletin, do the upload again. Do not try to upload more than five times. If the system does not upload after the fifth attempt, refer to the Garmin Line Maintenance Manual, Revision T or later, Appendix B.4 Software / Configuration Troubleshooting. If the system still does not upload, contact Cessna Propeller Aircraft Product Support: Telephone 316-517-5800 or FAX 316-517-7271. Do not cancel a software or configuration upload that is in progress. Let the system either successfully load or fail. NOTE 2: If the alert chime comes on at any time during the accomplishment of this Service Bulletin, you can go to the Alert Configuration page in the GDU page group, push the ACK softkey, this should make the chime stop. 1. Prepare the airplane for maintenance. A. Make sure that the airplane is electrically grounded. B. Remove the gust lock. C. Make sure that all switches are in the OFF/NORM position. NOTE: The instructions will have multiple steps to turn on electrical power and avionics, for Cessna airplanes this will be the STBY BATT, BAT MASTER and AVIONICS BUS 1 and BUS 2 switches. There will also be instructions to pull or push in the PFD and MFD circuit breakers, for Cessna airplanes there are three circuit breakers. The instructions are generic in nature and the applicalbe circuit breaker or circuit breakers for the PFD should be pushed in. For the PFD it is advisable to push in the PFD circuit breaker on the ESS BUS before the circuit breaker on the AVN BUS 1. The Cessna PFD and MFD cirucut breakers are as follows: • PFD Circuit Breaker on ESS BUS • MFD Circuit Breaker on AVN BUS 2 • PFD Circuit Breaker on AVN BUS 1 D. Pull the MFD and PFD circuit breakers: E. Connect external electrical power to the airplane. 2. Clear user settings as follows: NOTE: Clearing user settings will remove user data including user waypoints, pilot selections, and stored flight plans.

If ESP remains engaged for 10 seconds (non-consecutive) in a 20 second interval, the system will engage the Autopilot (AFCS) in LVL-LVL mode, which then enables automatic pitch trim authority. This can be unexpected when intentionally operating the airplane in some flight conditions such as during training flights with slow flight maneuvers or power off stalls. COMPLIANCE RECOMMENDED. This service document should be accomplished at the next 100-hour or 12-month (annual-type) inspection.
