Air Canada as flight 837, a Boeing 767-300ER, took off from runway 36L Madrid-Barajas Adolfo Suárez Airport (MAD/LEMD), Spain.
During the take-off run, the tire tread from the left rear wheel of the left main gear detached and some fragments of the tyre were ingested by the number 1 engine. The crew continued the takeoff, shut down engine no.1 and requested to return to the airport while declaring an emergency.
Due to maximum landing weight considerations, the flight crew decided to hold at 8000 feet for several hours to consume fuel.
In the meantime the landing gear was inspected by a Spanish Air Force McDonnell Douglas EF-18M Hornet fighter aircraft. The pilot of the Hornet confirmed one of the tyres was blown.
Subsequently, a safe landing was carried out at 19:06 LT.
The aircraft was repaired and resumed service on 14 February 2020.
Probable Cause:
Causes/Contributing factors:
The investigation has determined that the incident involving the C-GHOZ aircraft was caused by the presence of a sharp foreign object (FOD) on runway 36L at Madrid-Adolfo Suárez Airport, which punctured tyre number 5 on its left main landing gear and resulted in the explosion of the tyre and other secondary failures.
