Emergency Battery Maintenance
The Emergency Gyro and Emergency Lighting Batteries are an important part of your Westwind’s operating systems. Chapter 5-25-00 of the 1124/1124A Westwind Maintenance Manual requires the batteries to be checked every 200 hours or 3 months. Many people consider this requirement to be a nuisance. Quite often we find the batteries have been run down or their inspection interval was ignored. Do not let this happen to you. Take the time to check your batteries. Try putting them in sync with your “A” Inspection, if possible. If you are tracking them by calendar time, be sure to give yourself enough turn time, as they require 16 hours to charge. Considering their importance in the event you should need them, you will be glad you took the time to ensure their airworthiness.
