2.5.3 Lightning Strike Maintenance
Proper electrical bonding of all metallic components is critical for the protection against the effects of
lighting. Severe corrosion may inhibit a component’s ability to bond to the aircraft’s electrical ground
plane.
The following summarizes maintenance practices which are implemented to maintain adequate lightning
protection for the aircraft. See Section 4, Table 4-1 for exact maintenance requirements and associated intervals:
•
A
1000-hour
visual inspection of all G1000 equipment
, including voltage suppressors, resistors, fuses,
etc.
• A
n electrical bonding check
of G1000 equipment every 1000 hours or anytime a lightning strike occurs
or is suspected
.
• Regular replacement (every 2 years) of all five 3.2 Amp slow-blow fuses ensures they are in fresh
condition.
• Replacement of voltage suppressors, resistors, and fuses anytime a lightning strike occurs or is suspected.
