Sequence of events:
When they took off, it was evening, they got to some 7,000 feet, and had
retracted their flaps and were cleared high speed, they were at about (?) 270
Apparently they lost nº 3 ENG, (it) got torn OFF and when separating from
pylon, hit nº 4 engine which also fell OFF the pylon. Crew was not aware engines
fell OFF airplane, just were aware of both of engines FAILURE. If they had looked
at nº 3-4 ENG gages, they would have seen N1/N2 RPM at ZERO, and EGT at
ZERO (indicating no windmill = indicates engine(s) are MISSING) -
F/O was PF - CAPT called ENG FAILURE CK LIST. and called AMS DEP declaring
emergency and requested return to Schiphol. They did not pull FIRE HANDLE as
there was no fire. F/E said "I will dump fuel now". They got vectors and descent
clearance. They were not aware of damage on some of L/E flaps on RH wing.
They probably also thought that the windmilling EDP and ADP from operating
ENG would power HYDR Syst. 3 and 4... but BOTH were in fact INOP.
CAPT called for DESC/APPR CK, then F/E said "completed" and gave an approx
VREF + 20 (for a 2 ENG approach).
CAPT called for Flaps 1. By moving Flaps to 1, L/E flaps started extending on LH
WING, and 1 set of RH wing only (due to damage). Also, ONLY INBOARD T/E
flaps EXT to 1, outboard remained UP (HYDR Syst 4 is failed). Then he called
Flaps 5. F/E called "we have split flaps". All L/E flaps were now deployed on LHwing, only 1 or 2 on RH wing... Big Lateral control PROB...
Capt said I GOT THE PLANE to F/O who said OK.
F/E was doing more check-lists (2 GEN FAILED), and 2 ENG APPR briefing to
Then Capt said "is HYDR working ok on 3 and 4...?" F/E said "negative".
Capt said EXT flaps ALTERNATE (ELEC).
The outboard flaps being UP (nº 4 Hydr failed) kept the OUTBOARD ailerons
INOP, lost all lateral control. Only 2 spoilers operated on each wing for lateral
control, and inboard flaps.
F/E started ALT FLAPS (ELEC) extension, but being very slow, outboard T/E flaps
could not be extended on time to permit outboard aileron to operate.
RH wing stalled. They crashed.
When we play this scenario in the simulator, all works well IF we do
ALTERNATE (ELEC) flaps FIRST. And WE SAY that HYDR nº 3 and 4 are INOP.
