Visual Inspection
A. Verify that proper communication is being presented to the cockpit to validate the TB17
is transmitting data appropriately. To perform this, be sure that aircraft power is off (and
has been off for more than 1.0 hour – this is to assure that the battery is in sleep mode).
Turn the aircraft power on (this places a load on the TB17 and places it into active
mode) and verify that the three communication signals are present for 3 seconds.
B. Remove the unit from the aircraft. Visually inspect the exterior of the battery casing for
signs of damage or wear. Verify that the lid is secure and not loose. Verify that no
damage has occurred which would prevent the battery from maintaining its air-tight
seal. If any wear is apparent which has not compromised the case, inspect the battery
area of the aircraft for any signs of improper installation.
C. Visually inspect the power terminals and Communication connector. Verify that no
connectors are loose and there are no signs of damage, wear or corrosion.
D. If any of the above conditions are present, the unit must be evaluated and tested for
repair or replacement by an authorized repair facility.
