Bell 407 helicopters must now inspect and fix wiring
What happened
The US aviation regulator now requires owners of certain Bell 407 helicopters to inspect and fix electrical wiring. This means operators must perform a one-time check for chafing and make specific repairs to keep their aircraft flying.
Why it matters
This is a specific safety directive for a single helicopter model. It ensures that a known electrical wiring issue in these aircraft gets fixed. This prevents potential electrical failures and keeps the helicopters safe to fly.
The signal
Watch for any reports of electrical issues in Bell 407 helicopters after the compliance deadline, which would show if the fix worked.
