THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO

CONCURRENT REQUIREMENTS
Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND
Accomplishment of this service bulletin will make sure the greenband limits for the trim control result in safe
limits for take-off with a stabilizer mis-trim when an airplane with blended winglets has a lighter take-off weight
with the load in an aft position, a flap detent position of 10, 15 or 25, and a high take-off thrust. If this service
bulletin is not done, the trim control limits will allow a mis-trimmed take-off during which airspeed cannot be
controlled, which can result in unsafe flight conditions.
The trim control system was recently analyzed for nose-up mis-trim occurrences during take-off for airplanes
with blended winglets and was found to not be in accordance with the certification rules in specific conditions.
The greenband limits for trim control were moved in the nose-up direction for 737-700 airplanes with blended
winglets during development to be in accordance with certification criteria for nose-down mis-trim conditions.
The recent analysis found that at higher flap detent positions, with lighter take-off weights and a high take-off
thrust, the trim control greenband limits are incorrect, which could cause the take-off stabilizer trim position to
be set outside safe limits for take-off. The incorporation of this service bulletin will make sure that the nose-up
pitch trim will be set within safe limits for take-off.
For 737-700 aircraft with blended winglets certified by Boeing type certificate, this service bulletin, together with
Aviation Partners Boeing Service Bulletin AP737-27-002, gives instructions to replace the control stand stabilizer
trim lightplates in the flight compartment with one that has smaller greenband limits and to change the location
of the nose-up take-off warning limit switches. This service bulletin also gives instructions to install new Flight
Management Computer (FMC) Model/Engine Database (MEDB) software, which includes revised take-off
settings due to the smaller greenband limits.
