### Apr°/70 55-46 102. SparesAffected

No Boeing supplied spares.

B. Reason

To improve the service life of the horizontal stabilizer center section rear spar web.

C. Description
The horizontal stabilizer center section rear spar has a riveted web in the bay between BL 14.0 and Stabilizer Station 32.08. Fatigue tests at Boeing indicate cracksmay occur at the upper fastener holes in this riveted web. If cracks in the riveted web are allowed to progress, damage may occur to the rear spar forging. No cracks have been reported on in-service airplanes.

To reduce thepossibility of cracks and improve the service life of the spar or web on earlier airplanes, operatorsmay install an additional web on the opposite side from the existing web. On later airplanes, the existing web may be replaced with one of thicker material.

It is suggested that this rework be accomplished atmajor overhaul nearest to 20,000 hours.

D. Compliance Compliance is optional.

E. Approval
The modification described herein has been approved by the FAA Designated Engineering Representative at The Boeing Company.

F. Manpower Approximately 16man-hours and a crew of 2men are required to accompish this modification.
