Lightning Strikes
I'm looking for any information on the procedure for dealing with a lightning strike. I would have expected this to be covered somewhere, i.e Checklists, QRH, Flight Manual, Ops. Manual.? Can anybody suggest anything! Cheers.

Lightning Strike in Flight
The procedure in Table 22.1 must be applied after a lightning strike while airborne.
Table 22.1 – Procedure after Lightning Strike
Circuit breakers ............................................................ ........ Check
Only reset a tripped circuit breaker if the associated service is essential to
continued safe flight. Only one attempt is allowed.
Headings ………………………………………………………… Check
Check the magnetic compass and heading system for normal indication.
Engine indication ……………………………………………… Check
Check the engines for normal indications; if an abnormal situation exists apply the
appropriate procedure.
In an engine shuts down, analyse the circumstances and consider an air-start.
Pressurisation ………………………………………………….. Check
Check the pressurisation system for normal indications.
Flight controls ………………………………………………….. Check
Check all flight controls for freedom of movement.
Verify that slats/flaps and speed brakes are functioning correctly; observe the
operating limits.
Fuel System …………………………………………………….. Check
Check the fuel system for normal operation.
Monitor fuel remaining and fuel consumption to check for fuel leaks.
Altitude …………………………………………………………… Maintain
Do not climb the aircraft after a lightning strike, unless required by performance
(climb or obstacle clearance) or operational contingencies.
If any structural damage is suspected, apply the EMERGENCY DESCENT
procedure.
Aircraft other systems ………………………………………… Check
Check all aircraft instruments using a panel scan sequence.
Apply the associated emergency/abnormal procedure if any failure is discovered.
Consider landing at the nearest suitable airport if any unsafe condition is
discovered.
