So to be sure when my plug electrode went a cylinder went with it and it was in and out. Let's say DA was 5 or 6000. And let's say I did go full mixture to get out in front of a in bound King Air.
Two weird things here the electrode was found. So probably just departed. The plug might have still sparked if it was not covered in crap. And as I always say the plugs tell a story.
I cannot put a picture up here, but the plug in question is in bad shape.
Part of the reason we are given for paying high prices is traceability of parts. If you are going to have traceability then that needs to be used when there is a problem with a batch. The part number given in the report does not bring up a plug reference. So I think it is the batch number.
To be sure Tempest did ask for the 4 fine wire plugs back and provided 8 massives for free.
I always hope I have enough skill to stall it into the trees tail first. So they are partly dead for several reasons. Poor pilot technique in engine operation, deciding to take off High DA, was the engine even running well prior to taking off?, and not crashing well. Had the engine operation been better he might have had one of two plugs running in that cylinder, but I would guess running rich had more than one plug fouled and maybe across several cylinders. You would have thought the FAA lab would have checked all the plugs. Or did I miss that part.
I pulled all my plugs and checked them, replaced with a spare I carry, did several run up and fast taxis . Flew it home. Several hours late.
