On June 19, 2009, a Boeing 767-300, registration SP-LPA, operated by LOT Polish Airlines (flight number LOT 2) departed O'Hare International Airport, Chicago, Illinois (ORD) destined for Warsaw, Poland. In the vicinity of North Bay, Ontario, Canada, while cruising at FL 330, the aircraft experienced a sudden and uncommanded overspeed condition, stick shaker, and illumination of the left and right electronic engine control (EEC) caution lights. A similar condition occurred again in a holding pattern as the airplane burned off excess fuel prior to making an uneventful landing at Lester B. Pearson International Airport, Toronto, Ontario, Canada.

The event is being investigated by the Transportation Safety Board (TSB) of Canada. All inquiries should be directed to the TSB at:
