"Applicability: All Model 737-100, -200, -200C, -300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes; certificated in any category. "
However, once we alert on all these airframes, there is only genuine interest in FCMs with particular part numbers and serial numbers.

Apparently not so much the doom merchant. Don't get me wrong... sensationalism IS normally the order of the day, every day. But this time it seems rather subdued.
