March 20 (Reuters) - Boeing ( BA ) has made the decision

to keep B737 jet production below 38 per month, and will only

accept a fully conforming fuselage from supplier Spirit

AeroSystems ( SPR ) at its Washington state factory, CFO Brian

West told analysts on Wednesday.

Manufacturing quality at both Boeing ( BA ) and the supplier are

facing increased scrutiny following a Jan. 5 incident in which a

door plug blew off a 737 Max 9 plane mid-flight.
