WASHINGTON, Nov 11 (Reuters) - Boeing Commercial

Airplanes quality chief Elizabeth Lund -- who has spearheaded

the planemaker's improvement plans -- will retire in December,

the company said Monday.

Elizabeth Lund, a 33-year veteran Boeing ( BA ), had been named to

the new position of senior vice president of quality for its

commercial planes in February after the crisis sparked by the

Jan. 5 mid-air panel blowout of a new Alaska Airlines 737 MAX 9.

In June, the NTSB said Boeing ( BA ) violated investigation rules when

Lund provided non-public information to media and speculated

about possible causes.
