Among others.
The GPS signal encrypting module for IRS/GPS type LN-100G
was not installed hence GPS INOP, pilots usig GARMIN 196...
Pilots turned off GPWS, no bank or GP warnings heard.
PF MFD set to QFE, C/P MFD set to QNH.
Ceiling 60-90m, PAR approach. Both pilots looking out for the runway,
ecpecting to see it because ATCO told them "on slope",
while they were 120 m above,
nobody looked on the instruments after turning of A/P.
Increasing, uncontrolled bank to 19 then 67 deg, not corrected,
8 sec before impact stall, nose down 21 deg.
Spatial disorientation, bank, stall, crash.
