An Air Transat Boeing 737-800, registration C-GZEH performing flight TS-41 from Paris Orly (France) to Toronto,ON (Canada) with 2 crew, was initiating the takeoff run from Orly with the crew adjusting power to set TOGA when thick white smoke appeared in the cockpit prompting the crew to reject takeoff, the smoke dissipated as soon as the power levers were brought to idle. The aircraft vacated the runway and returned to the apron.

The Canadian TSB reported the aircraft (MSN 2615, former tail number F-GZHE) was on its very first flight for Air Transat and was positioning to Toronto for delivery. The previous operator’s maintenance had prepared the aircraft but had overserviced the engine oil levels of both engines. Both engine oil reservoirs were drained in accordance with the aircraft maintenance manuals and an idle run leak check was completed with no anomaly.
