The left MLG leg was beyond the runway edge lighting line, and remained approximately
at 5 m from the runway shoulder end, that is, at 40 m from the axis of runway 33,
that has 60 m of total width (distance between the white lines of runway edges), and
at 146 m from the axis of the taxiway J-1. The nose landing gear also remained at
approximately 5 m from the runway shoulder end and at approximately 120 m from
the axis of taxiway J-1.
Therefore, that left MLG leg remained at 313 from the intersection of the axes of runways
33-15 and 36R-18L.
When the runway could be inspected, it was noticed that starting in the point the aircraft
had stopped and coming back in the sense towards the threshold of runway 33
(i.e. going in the sense contrary to the movement of the aircraft during the landing roll),
tracks of the wheels of the left and right MLG legs could be clearly noted. The tracks
consisted of eight dark lines that corresponded to the sides of the tires showing that all
the wheels had burst. At 60 m form the point where it was stopped, the track of the
left leg crossed the runway edge lighting line (at 2 m from the next runway edge light),
and 60 m backwards it crossed the white line of the runway side stripe. During the previous
60 m it could be seen that the wheel rims number 1 and 5 (both outboard wheels
of the left leg) had dragged along the runway, although no appreciable grooves or
other damage to the runway surface was noticed.
At 240 m from the point it finally stopped (i.e., at 73 m from the intersection of runway
36R), the tracks of the right MLG leg disappeared at a point located 8.2 m to the
left of the runway axis.
The tracks of the left leg continued being visible going backwards, they crossed the
intersection of runway 36R and started softening and blurring being confused with the
tracks of other aircraft 630 m aft of the point where the aircraft stopped (i.e. at 900 m
from the threshold of runway 33).
The damage to the aircraft consisted of the burst of the eight wheels of the left and
right legs and damage to the brake assemblies number 1, 5 and 6 with the following
description:
Wheels 1, 2, 5 and 6 showed heavy rubbing with loss of material of the rim and tire
burst, due to friction with the runway.
Wheel 3 had friction in the rim and tire burst due to contact with the runway.
Wheel 4 had friction in the rim with loss of material and tire burst due to friction with
the runway.
Wheels 7 and 8 showed tire burst due to friction with the runway but the rims did not
have noticeable damage.

Technical report IN-062/2002
Figure 6. Wheels 3, 4, 7 y 8 (right leg; seen from the rear right angle) after the aircraft stopped
on the runway. The white line is the runway side stripe marking of 33. Note the two narrow
tracks of every wheel after they burst
The brake assemblies 1, 5 y 6 showed heavy rubbing with loss of material in the fitting
and in the brake disks, due to friction with the runway.
When the aircraft was inspected in a hangar, there were no signs of fire having affected
the landing gear. The lower part of the wing and the inboard flaps did not show
any traces of smoke.
The maintenance personnel of the operator replaced the wheels of the aircraft on the
runway and then the aircraft was towed to a hangar.
1.13. Medical and pathological information
There were no personal damages during the event.

1.14. Fire
At Tenerife Norte Airport there was no fire, although there was smoke coming out the
wheels due to the high temperature reached by the brakes.
At Madrid-Barajas Airport, a lot of smoke was seen from the tower immediately after
the incident. Another aircraft said on the radio that EC-IDF had fire on the wheels. The
fire fighters were advised by the tower around 13:06 h, and at 13:09:45 h the crew
confirmed to the tower that they were around the aircraft. At 13:09:55 h, the tower
had already received confirmation from the fire fighting crew that the fire was extinguished.
According to their report, the fire fighters, which had been warned by the tower, reached
the area of the incident and found all the wheels in fire, and they positioned
around the aircraft and quickly extinguished the fire and then continued cooling the
gears. They used a total of 250 kg of chemical powder and 1750 l of foam, although
this later figure was higher than the amount normally needed due to the malfunction
of one of the extinguishing vehicles.
According to some information gathered later on, the flames were clearly visible from
the area of the south tower of the airport. However, when the aircraft was inspected
in a hangar, there were no rests of combustion in any part in the wheel area.
