The pilot then declared "PAN PAN" due to flight control issues. The aircraft landed without issue on Runway 05 around 2349Z. Emergency vehicles were dispatched. No operational impact.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The flight crew of WJA2507 from Puerto Plata, Dominican Republic (MDPP) to Toronto/Lester B. Pearson, ON (CYYZ) on January 28, 2022 reported on Log Page AM51564 that on final approach they selected "flaps 30" and the flaps stayed at 15 units. A go-around was conducted and the aircraft landed in the flap 15 configuration without incident. It was noted that, after landing, the flaps travelled to 30 units, with indication in the green and no asymmetry noted. 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.

The aircraft turned suddenly to the left, and the captain attempted to regain control of the steering by applying the right brake and reversing the thrust of the engines. The aircraft exited the runway, hitting a runway light with the nose wheel, and when the landing gear was on gravel, directional control returned to normal. The captain then taxied the aircraft to the apron without incident. There were no injuries. After checking with maintenance, the main landing gear assemblies were replaced, as well as the nose wheel tire. The quality of the brakes was checked during the dismantling of the wheels and the brake tests did not reveal any faults. The aircraft was returned to service.
UPDATE: Aviation Incident Report #17064: As soon as a Sky Jet M.G. Beech A100 (C-GJBV/LSJ512) made contact with the ground, the aircraft went off the runway on the left side of the runway. As it was going off the runway, the aircraft struck a runway light. Based on preliminary findings, the left-side brake became wedged, if evidenced by the tracks left on the pavement. The aircraft was able to get back on the runway and apron on its own power. No impact on air operations. After a visual inspection, the aircraft departed normally for its next destination.
