**Number: A3516** 

### Summary Date: April 04, 2008 ATA System: 5510 **SUBJECT:** STABILIZERS - Horizontal Stabilizer and Horizontal Stabilizer Center Section - Inspections

THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH 1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.

**CONCURRENT REQUIREMENTS**

None.

**BACKGROUND** Boeing Service Related Problem (SRP) 707-SRP-55-0033 is related to this service bulletin. Service bulletin 707A3516 is issued to call for inspections of 707 horizontal stabilizer details listed in the Supplemental Structural Inspection Document that are exposed to an accelerated fatigue environment. This accelerated fatigue environment is generated by frequent use of the affected airplanes for training flights that include multiple touch-and-go cycles. This frequent use of the airplane for this type of training has been most prevalent by the military operators of commercial model 707 and 720 airplanes. Boeing has received three reports of fatigue cracking in the rear spar upper chord, at a location near side of body. In all cases the fatigue prevention and fail-safe improvement modifications of service bulletin 707A3313 had been incorporated. The fatigue cracking is considered to be early in the life of the modified structure, and is generated by frequent use of the effective airplanes for training flights that include multiple touch-and-go cycles. Simultaneous to the release of service bulletin 707A3516, service bulletin 707A3515 is released to specifically address fatigue cracking in the stabilizer rear spar upper chord. The reported cracking is an indication that other details in the horizontal stabilizer installation directly affected by this type of airplane usage are more likely to develop early fatigue damage as well. The actions of service bulletin 707A3516 are necessary to adequately detect early fatigue cracking.April 04, 2008 A3516 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 6 of 22



### BOEING SERVICE **BULLETIN A3516 ALERT ALERT**  The ability to interchange the horizontal stabilizer from airplane to airplane is of significance, since these stabilizer changes are known to occur. This makes it necessary to implement the inspections for early fatigue cracking on all affected airplanes at the time stated in the 1.E Compliance, regardless of the airplane current usage. **ACTION** (PRR 18101-2RS ) Cycle Definition: To adequately account for in-flight training maneuvers, incorporate the cycle counting procedure defined in this service bulletin. Inspections: Complete the inspections in accordance with the methods and times stated in this service bulletin.

**EFFECTIVITY** All 707 and 720 Airplanes. See Paragraph 1.A.1 for effectivity.

**COMPLIANCE** The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to this service bulletin. The Airworthiness Directive will make the compliance tasks and times given in this service bulletin mandatory. See Service Bulletin Paragraph 1.E. for compliance information.

**INDUSTRY SUPPORT INFORMATION** Boeing warranty remedies are not available for the inspection procedures given in this service bulletin.

**MANPOWER** See Supplemental Structural Inspection Document, D6-44860 for manpower requirements.
