## Discrepancy

(CAN) JUST AFTER TAKEOFF, A SPARK WAS NOTICED IN THE TOP R/H CORNER OF THE L1 WINDOW. A SECOND SPARK WAS FOLLOWED 5-10 SECONDS LATER AND THE OUTER PANE OF WINDOW CRACKED. ATC WAS ADVISED AND THE FLIGHT ENTERED A HOLDING PATTERN TO MEET MAX LANDING WEIGHT BEFORE RETURNING. THE AIRCRAFT LANDED UNEVENTFULLY AND MAINTENANCE REPLACED THE L1 WINDOW AS PER AMM 56-11-11-400-801. (TC# 20141110010)
