Narrative:
A Boeing 767-283ER passenger plane, XA-TOJ, sustained substantial damage in a tailstrike accident during takeoff from Madrid-Barajas Airport (MAD), Spain.
At 14:58 Aeroméxico flight 002 took off from Madrid on a scheduled flight to Mexico City, Mexico. On board were three pilots, six flight attendants and 154 passengers. During takeoff the tail impacted runway 36L, causing substantial damage to the underside of the tail. While climbing to FL140 the cabin failed to pressurize as expected. Then the oxygen masks deployed in the cabin. At 15:20 the flight crew informed the controller at Madrid that they were returning due to pressurization problems. The airplane entered a holding pattern and landed safely on runway 18R at 16:25.

Air Europa flight 71 to Caracas, Venezuela took off at 15:29 and suffered a punctured nose gear tyre, probably after running over debris left on the runway after the Aéromexico tailstrike. AEA71 was the seventh flight to take off from runway 36L following the Aeroméxico plane. The Airbus A330-200, EC-JPF, entered a holding pattern off the southern coast of Portugal at FL100 and landed safely back at Madrid at 19:39.

Causes (translated from Spanish):
The accident occurred because the aircraft rotated at a speed much lower than necessary because it had been incorrectly calculated during the dispatch, based on the weight of the aircraft with zero fuel (ZFW) instead of the takeoff weight of the aircraft (TOW). Then the error was not detected by the crew when entering data into the FMS.
Contributing factors:
- The On-Board Performance Tool (OPT) was recently introduced in the company.
- The experience of both the dispatch officer as well as crew members was insufficient in this area.
- The On-Board Performance Tool (OPT) was not installed at the Madrid station so that the transmission of the information was not performed according to procedures.
