The occurrence
On , the WestJet Airlines Ltd. Boeing 737-7CT aircraft (registration C-GWCN, serial number 34157) was conducting flight WJA1447 from Harry Reid International Airport (KLAS), Nevada, United States, to Edmonton International Airport (CYEG), Alberta, with 5 crew members and 109 passengers on board. At approximately 1825 Pacific Standard Time, the aircraft took off while aligned with the right edge of Runway 01R, and its right nosewheel contacted 8 runway edge lights. The flight crew were unaware of the misaligned takeoff and subsequent contact with the edge lights, and the aircraft continued to CYEG, where it landed uneventfully. None of the passengers or crew members were injured. The next day, WestJet Airlines Ltd. maintenance noted minor damage to the right tire on the nose landing gear and replaced both nosewheel tires before releasing the aircraft back to service. The airport operator at KLAS discovered the damage to the runway edge lights 32 hours after the occurrence; it notified the airline operator of the damage to the runway edge lights 8 days after the occurrence.

TSB investigation process
There are 3 phases to a TSB investigation
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
- Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.
