Go After V1
Iwill tell you a story that happened with me long time ago,
It was L1011/500 250 pax on board, take off weight was around
200000 kgs, 400000 lbs , just after V1 we heard a loud bang, we
continued rotation. just after leaving the ground a black thing
just flew infront of the winshield and went straight into engine
no2, at that time sever vibration shook the plane, F/E started
screaming Vibration on eng 2, tower also reported lots of smoke
from our plane, eng 2 throttle was moved back to idle and
vibration stopped, at that time the lead cabin crew flew to the
cokpit reporting smoke from the left engine, we looked at engine
no1 parameters, and it had the high EGT light on, limitation
was 800 c for max 20sec, now we thought that F/E made a mistake
reporting eng2 instead of eng no 1, as we learned in the sim that
sever damage is always accompanied by high temp, so eng no 1
was retarded below temp limit and eng n02 thottle was addvanced
slightly, which brought vib back, we realised that 2 engines were affected,
it took us 10 min to reach 1000t AGL, luckily no high terrain around,
Engine no 2 was shut down, and no1 was kept below High EGT limit.
We started dumping fuel and the tower reported lots of rubber
on the runway, which meant one tire was lost. fuel was dumped
to the minimum which took almost one hour, we dropped the
landing gear and made a low pass over the tower, which reported
a left tire was gone.
We landed on the right side first, did not use left reverser and stopped
the plane on the runway,no evacuation was made as there was no fire
reported.
The main tire blow up at V1, hit the left wing and ruptured the fuel
tank in front of eng 1 and went straight in front of the windshield
into eng no 2.
It is always safer to go airborne, deal with the problem, and come back
and land.
