An Aircraft Gyro Reminder That Will Save You Thousands of Dollars

 Submitted by Curt Campbell, avionics tech rep

There have been many articles and videos over the years, written and produced by tech reps and technicians at Duncan Aviation about the proper care and maintenance of an aircraft gyro. 

However, it wasn't long ago that I got a call from an operator who was having precession errors and failures to erect on his gyro. It didn't take long for me to figure out that the cause of his issue was the result of the gyro not being allowed enough time (20 minutes) to spool-down before the aircraft was moved.

He stated his crew wasn't aware of this required spool-down time. This oversight unfortunately required a complete overhaul of the gyro, costing several thousand dollars.

Time for another reminder..

I encourage you to share this information with all personnel tasked with aircraft movement/maintenance in your company. Below are links for your use. You can bookmark them for future reference.
