Narrative:
Continental Air Lines Flight 1713, a Douglas Dc-9-14, crashed on takeoff from Denver-Stapleton International Airport, Colorado, USA.
The aircraft was cleared for a takeoff from runway 35L, 27 minutes after having been de-iced. On takeoff, the DC-9 over rotated. The aircraft sank back and the left wing struck the ground, causing it to separate from the fuselage. The left side of the cockpit and forward fuselage struck the ground next and the aircraft continued to skid inverted.
Of the 82 occupants, 28 lost their lives.

Both pilots were relatively inexperienced in DC-9 operations. The captain had 166 hours on type, of which 33 as captain; and the first officer just had 36 hours on type.

Probable Cause:

PROBABLE CAUSE: "The captain's failure to have the airplane de-iced a second time after delay before take-off that led to upper wing surface contamination and a loss of control during rapid take-off rotation by the first officer.
Contributing was the absence of regulatory or management controls governing operations by newly qualified flight crew members and the confusion that existed between the flight crew and air traffic controllers that led to the delay in departure."
