redundant failure

"As the person flying when the lighning strike occured, wouldn't I be best placed to know if something was up?

All systems continued to function normally, aircraft continued to handle normally.

Why on earth would I disrupt the days flying programme and upset literally thousands of passengers?"

To reply to your query without the, us and them comments, glass house comments. etc. as to why you are NOT best qualified:
below are the systems of the aircraft that require checking on the aircraft I work on. Please pay particular attention to systems that are active but not used in normal operation. Maybe check the aircraft maint manual for your type you maybe surprised.


NOTE: The following inspection shall be done whenever aircraft is subjected to lightning strike.

(1) Using a torch and inspection mirror, visually inspect all engine electrical connectors and wires for evidence of damage. (Ref. Honeywell EM 72-00-09, page block 801, Honeywell EM 72-00-10, page block 801, Honeywell EM 72-00-11, page block 801, Honeywell EM 72-00-16, page block 801, AMM 74-20-01, page block 201, AMM 74-20-02, page block 201, AMM 75-10-03, page block 201, AMM 76-20-02, page block 201, AMM 76-20-03, page block 201, AMM 76-20-04, page block 201, AMM 77-12-01, page block 201, AMM 77-20-01, page block 201, AMM 77-20-02, page block 201, AMM 77-20-03, page block 201).

(2) Perform a ground run to determine proper operation of all engine electrical components and sensors as follows:-

(a) Ignition system.

(b) Vibration system.

(c) Anti-icing system.

(d) Rotor speed indicators.

(e) Oil system indicators.

(f) ITT system.

(g) Fuel flow indicators.

(3) Perform overspeed trip system redundancy and latch check.
MRB/MPD REF : 72-17B,72-17C

When a lightning strike has been reported, the aircraft and/or engine must be inspected for damage, and tests performed before the next flight (Ref. AMM 05-51-15, page block 1). All details of system malfunctions that occurred at the time of the strike, and subsequent to it, must be obtained from the flight crew.
In the following inspection requirements, the tasks are divided in phases as follows :-
Phase 1 - the initial inspection phase which, if found serviceable, will require no further action.
Phase 2 - the repair and replacement phase, if damage is found at phase 1. All structural repairs are to be performed in accordance with the procedures detailed in the Structural Repair Manual (SRM).
Phase 3 - used where tests are required after work at phase 2.

2. Inspection procedure
A. Equipment and materials

ITEM DESIGNATION
(1) Access platforms 11 to 24 ft. (3.35 to 7.32m).
(2) Warning notices.
