Dear Rolf,

further to our previous discussion, I would like to react to your post. Special thanks to Pilot and Flugzeug forum for activation of our account.

AIR TEAM service has provided you with upgrade of your cockpit for dual GI 275 between May 16th to June 24th 2021. The installation was extended for two weeks due to additional defects, which you requested to fix or which were found on the aircraft, such as:

-replacement of regulator for solid state
-replacement of oil and filter
-leaking valve, which required vacuum pump to be removed, cleaned and resealed
-disconnected cabling from one of the engine sensors
-paint repair
-cleaning, polishing
-other requests for minor additional maintenance

After your departure on June 24th 2021, you reported several issues with the GI275. Although our warranty conditions state that you need to visit us in LKKU to troubleshoot and fix any warranty claims, we have decided to go step ahead and provide you with onsite troubleshooting in Augsburg to save you trip to LKKU and show good favor. We have managed to organize our trip the next business day (Monday-Tuesday) and solve all the claims.

Now,
· after nearly two years since we completed our installation
· after you have exchanged both original GI275 at multiple aircraft maintenance facilities
· after you modified the entire center stack for the new dual GTNs installation
· after you have been provided with Garmin compensation for the GI275 troubles
· after not claiming any warranty case with us

you ask us to pay for the cost of the GI275 avionics maintenance, finding wrong autopilot rele installation and delivery of the new rele, while the defect occurred nearly 2 years from our installation, but only 6 or 7 hours after the other maintenance facility troubleshooting and there is no proof that we have ever installed the wrong rele to your aircraft.

When we don't respond to your claims as you expect, we are badly damaged by your reviews and posts at this forum.

I fully understand, as other forum members noted, that upgrades of the avionics on the aircraft are sometimes challenging as you are combing older airframe, electrical and avionics systems with brand-new avionics products. Also, when something goes wrong, not only customers/pilots may have hard time to correctly evaluate the root cause of the defects as some of the defects happens accidentally or may have multiple reasons.

At AIR TEAM, we are always focused on our customer's satisfaction, and each upgraded aircraft with new avionics is undergoing extensive ground and flight testing prior to aircraft handover back to the customer. Also, if anything goes wrong after the aircraft handover, we are doing our best to provide after sale support and assistance.

Thanks for your understanding and wish you happy weekend flying,

Petr Polak and AIR TEAM service team
