Commercial Airplanes 737 Service Bulletin ALERT SummaryNumber: 737-30A1063Original Issue: November 16, 2011 ATA System: 3000 SUBJECT: ICE AND RAIN PROTECTION - PITOT AND STATIC - Air Data Probe Anti-Icing System
- Air Data Probe Heat Automation Installation
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.
ACTION (PRR 38275-160S) Get access to the flight compartment at the P5 overhead panel. Change wires and replace the P5-9 window/pitot heat module. At the P18 circuit breaker panel, replace two circuit breakers, install relay supports, relays, decals and change the wiring.
Get access to the electrical/electronics compartment. At the E2-2 electronics shelf, change wiring. At the E3-1 electronics shelf, change the wiring.
Do an operational test of the anti-icing system for the air data probes.
