WestJet (WJ) maintenance met the aircraft and performed a Built-in Test Equipment (BITE) check on the Flap Slat Electronic Unit (FSEU), and found no existing faults. The previous flight leg showed a Trailing Edge Left-Hand (L/H) sensor fail. A visual inspection of the L/H flap position sensor and connector was accomplished, with no defects noted. Further troubleshooting was conducted in accordance with the Boeing Fault Isolation Manual (FIM) 27-51 Task 813, with no faults found and the Flap Slat Electronics Unit (FSEU) still showing no existing faults, indicating that this was an intermittent defect. As due diligence, the L/H flap position transmitter and connector D275 were replaced and tested serviceable, in accordance with the Boeing Aircraft Maintenance Manual (AMM) and the Standard Wiring Practises Manual, and a Required Inspection Item (RII) inspection was accomplished. The aircraft was returned to service and has flown one leg with no recurrence of the defect. WJ Reliability was contacted to identify negative trends from all operators and to identify if there are any Original Equipment Manufacturer (OEM) remedies being reviewed, with the following results: this is a condition known to Boeing that affects all operators and the OEM is working on a permanent fix. Although the Fault Isolation Manual indicates that the operator may choose to replace the Flap Position Transmitter or the Indicator or both, new information from a Fleet Team Digest from Boeing that was created on 12/30/2021 suggests that the operator may want to consider replacing both the transmitter and the indicator. Even though there were no defects on the last flight, WestJet is replacing the Flap Position Indicator prior to further flight, per the suggestion in the new Boeing Fleet Team Digest (Work Order 690253).
UPDATE: TSB Report #A22O0011: C-GAWS, a Boeing 737-8CT operated by WestJet, was conducting flight WJA2507 from Puerto Plata/Gregorio Luperon International, Dominican Republic (MDPP) to Toronto/Lester B. Pearson International, ON (CYYZ) with 6 crew and 158 passengers on board. While on approach into CYYZ for Runway 06L, the flight crew selected the flaps to 30 but subsequently noticed the flaps stopped and remained at 15. The flight crew went through non-normal procedures, performed a go-around and declared "Pan Pan" with Air Traffic Control (ATC). The aircraft performed a second approach for Runway 05 with the flaps at 15, where it landed without further incident with Airport Rescue and Fire Fighting (ARFF) vehicles standing by. Company maintenance inspected the aircraft, replaced the Trailing Edge (TE) Flap transmitters, the left TE Flap position transmitter connector, and the Flap position indicator, and the system tested serviceable.
