What I don't understand is why they are only checking the ones in the '87. Honeywell said there are over 6000 in service. Seems we should be checking them all.
It could have something to do with battery replacements performed on the units in storage intended for the 787 line.
Normally, I would expect line maintenance to be performed by techs trained and certified to do such work. Including watching for pinched wiring. So the question is: Who did the work on the units stored at Honeywell/Boeing? Perhaps the regulators were already made aware of this maintenance procedure anomaly and decided not to impose additional costs on their other customers.
