On January 3, 2004, about 02:45:06 UTC, 04:45:06 Local time, Flash Airlines flight FSH604 , a Boeing 737-300, Egyptian registration SU-ZCF, crashed into the Red Sea shortly after takeoff from Sharm el-Sheikh International Airport (SSH) in South Sinai, Egypt. The flight was a passenger charter flight to Charles de Gaulle Airport (CDG), France with a stopover in Cairo international Airport (CAI) for refueling.
Flash Airlines flight FSH604 departed from Sharm el-Sheikh airport with 2 pilots (Captain and First Officer), 1 observer, 4 cabin crew, 6 off-duty crew members and 135 passengers on board. The airplane was destroyed due to impact forces with the Red Sea with no survivals. The airplane had departed from Sharm el-Sheikh runway 22R and was airborn at 02:42:33 UTC, approximately 2½ minutes prior to the crash, and had been cleared for a climbing left turn intercept the 306 radial from the Sharm el-Sheikh VOR station located just north of runway 22R.
This climbing turn allows departing flights to gain sufficient altitude before proceeding over higher terrain located along the flight path to Cairo.

- At time 02:44:07, the F/O states “heading select” and the FDR records heading select mode engaging. This mode transition would have resulted in the reappearance of the flight director roll command bar. During this sequence, the aircraft’ left-bank continued to decrease at a slow rate until the airplane was briefly wings level. (4056 ft, CAS 199 kts, Hdg 139.5°, Pitch 19.8°, Roll 0.35° right)
Beginning at this time, the FDR of Flash Airlines flight FSH604 records a series of aileron motions that command a right bank and subsequent right turn.
- At time 02:44:18, the captain states “See what the aircraft did”. At this point the aircraft bank angle was approximately 12° to the right. (4824 ft, CAS 186.5 kts, Hdg 149.4°, Pitch 15.4°, Roll 12.6° right)

- At time 02:44:58, the captain states “Autopilot”. At the same time, the FDR records a large aileron motion to the left and the airplane begins rolling back towards wings level.(3068 ft, CAS 317.5 kts, Hdg 281°, Pitch 43.2° nose down, Roll 111° right)
- At time 02:44:58.8, the observer states “Retard power, retard power, retard power”
- At time 02:45.01.5, the captain states “Retard power”, and the FDR records both engine throttles being moved to idle.(Pitch 42.4° nose down, Roll 39.2° right)
- At time 02:45:02, the CVR records the sound of the overspeed warning.(1320 ft, CAS 382.5 kts, Hdg 306.9°, Pitch 40.6° nose down, Roll 30.2° right)
- Recovery from severe Right Bank and nose down pitch continued
- At time 02:45:04.3, the captain states “Come out”. Bank angle was 15.6° right, pitch attitude was 30.5° nose down, altitude was 421 ft, and airspeed was 411.8 KIAS
- At time 02:45:05, the CVR records a sound similar to ground proximity warning (180 ft, CAS 416 kts, heading 315.7°, pitch 25.4° nose down, right roll 19.3°),
A/C impacted the water at about 02:45:06 with last recorded data: – Bank Angle 19.3 to the right – Pitch Angle 25.4 Nose down – Vertical G. Load 3.96 (2.7) – Speed 416 Kts
Possible causes :
- Trim/ Feel Unit Fault (Aileron Trim Runaway)
- Temporarily, Spoiler wing cable jam (Spoiler offset of the neutral position)
- Temporarily, F/O wheel jam (spoilers offset of the neutral position)
- Autopilot Actuator Hardover Fault
Possible contributing factors :
- A distraction developing to Spatial Disorientation (SD) until the time the F/O announced “A/C turning right“with acknowledgement of the captain.
- Technical Log copies were kept on board with no copy left at departure station.
- Operator write up of defects was not accurately performed and resulting in unclear knowledge of actual technical status
- There are conflicting signals which make unclear whether the captain remained in SD or was the crew unable to perceive the cause that was creating an upset condition until the time when the F/O announced that there was no A/P in action.
- After the time when the F/O announced “no A/P commander” the crew behavior suggests the recovery attempt was consistent with expected crew reaction, evidences show that the corrective action was initiated in full, however the gravity of the upset condition with regards to attitude, altitude and speed made this attempt insufficient to achieve a successful recovery.
- The ECAA authorization for RAM B737 simulator was issued at a date later than the date of training for the accident crew although the inspection and acceptance test were carried out at an earlier date.
- Several recorded FDR parameters were unreliable and could not be used for the investigation.
No conclusive evidence could be found from the findings gathered through this investigation to determine a probable cause. However, based on the work done, it could be concluded that any combination of these findings could have caused or contributed to the accident. Although the crew at the last stage of this accident attempted to correctly recover, the gravity of the upset condition with regards to attitude, altitude and speed made this attempt insufficient to achieve a successful recovery.
