The following report has been rated as SEVERE RISK:
3/04/343 A6ERN 09-04-04 EK
764 JNB - DXB INVEST ACTIVE
RUNWAY OVER-RUN ON TAKE OFF
The report stated, that following a normal application
of the reduced flexible thrust, the aircraft
commenced its take off run, with the flaps set to 1+
F. Following the rotate call, the PF applied rearward
side-stick and, for approximately 6 -7 seconds the
aircraft nose did not move upwards. After that, the
nose rose and the PF selected 9° nose up, expecting
the aircraft to lift off. Very shortly afterwards the
crew felt a rumbling, selected TOGA (full) thrust and
about two seconds later the aircraft became airborne.
The initial climb out and thrust reduction was normal,
but as the aircraft was accelerated and flaps were
retracted an ECAM caution annunciated for FLAPS
LOCKED.
Since the flaps were now in an immovable position and
not fully retracted a decision was made to return. ATC
were informed and fuel jettisoned to maximum landing
weight. ATC advised that a runway inspection
had revealed damage to two runway end lights and that
the aircraft may have traveled about 150 meters across
the grass at the end of the runway, before getting
airborne.
In the absence of other warnings and no ECAM system
for displaying tyre pressure, the crew assumed that
the landing gear and tyres were unaffected. The
aircraft then returned for a non-standard
configuration (Flaps Locked) landing during which at
about 70 knots normal braking failed. The aircraft was
slowed using alternate brakes and came to a halt
approximately 150 meters from the end of the runway.
The fire services were in immediate attendance and the
main gear tyres were seen to be damaged and deflated.
There were no reported injury to the crew or
passengers. This incident is the subject of an ICAO
annex 13 investigation by the country of occurrence.
They have also invited a member of the local authority
as an accredited representative to the investigation
and have permitted airline participation, in an
advisory capacity.
