Service Bulletin
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.

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.

2. Spares Affected
None.
B. Concurrent Requirements
None.
C. Reason
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.
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.
D. Description
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.
