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 Refer to Paragraph 1.B., Concurrent Requirements.

BACKGROUND This service bulletin provides the instructions and the kits to change the anti-icing system for the angle of attack sensor, the total air temperature, and the pitot probes. The changes to the system will let the anti-icing system automatically supply power to heat the probes. The anti-icing system will automatically come on (AUTO) after engine start if the crew does not activate the system. If this service bulletin is not accomplished, the air data sensors could be unheated which could let ice form on the sensors, and cause erroneous air data. Unreliable air data can lead to loss of crew situational awareness which could cause failure to maintain safe flight and landing of the airplane.

Boeing has received reports that the Pilot Heat switch is not always set to ON.

Fleet Team Digest, 737NG-FTD-30-08002, is related to this service bulletin.

Boeing Service Related Problem, (SRP) 737NG-SRP-30-0032, is related to this service bulletin.

As a part of a service bulletin validation program, this change was completed on airplane YD591 by Service Bulletin 737-30A1063 Original Issue before the release of Revision 1 of this service bulletin. The change completed on airplane YD591 by Service Bulletin 737-30A1063 Original Issue is equivalent to the release of Revision 1 of this service bulletin. Airplane YD591 has the configuration of a Group 2 airplane.
