SUMMARY:

We are adopting a new airworthiness directive (AD) for all The Boeing Company

Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by

reports of an incorrect procedure used to apply the wear and corrosion protective surface coating to

attach pins of the horizontal stabilizer rear spar. This AD requires inspecting to determine the part

number of the attach pins of the horizontal stabilizer rear spar, and replacing certain attach pins with

new, improved attach pins. We are issuing this AD to prevent premature failure of the attach pins,

which could cause reduced structural integrity of the horizontal stabilizer to fuselage attachment,

resulting in loss of control of the airplane.
