Investigation Summary
Flight BG606 was a domestic scheduled flight from Dhaka to Sylhet. During the approach to Sylhet, the area was experiencing significant rainfall and poor visibility. The flight crew continued the approach and touched down significantly further down the runway than the standard touchdown zone. Due to the combination of the late touchdown and standing water on the runway causing hydroplaning, the wheel braking was ineffective. The aircraft exited the end of the runway at low speed. The nose gear collapsed or sank into the soft ground, and the airframe suffered structural damage that led to it being written off.
Final Conclusions
The investigation concluded that the aircraft overran the runway following a landing in heavy rain. The primary factors were a late touchdown significantly beyond the designated zone and the presence of standing water on the runway, which led to hydroplaning and rendered wheel braking ineffective. The crew's decision to continue the landing despite the unstable approach parameters and adverse weather conditions resulted in the hull loss.

Systems & Failure Modes
Braking System
The aircraft's wheel brakes were unable to provide sufficient deceleration due to the late touchdown and the presence of standing water, which likely induced hydroplaning.
Landing Gear
The nose landing gear sustained damage and collapsed after the aircraft exited the paved surface and entered the soft soil beyond the runway.
Interesting Facts
- 01The aircraft was a Fokker F28-4000, registration S2-ACZ, which was approximately 28 years old at the time.
- 02The accident occurred during a period of 'Kalbaishakhi' (Nor'wester) storm activity common in Bangladesh during April.
- 03The aircraft was subsequently declared a hull loss due to the extent of the structural damage.
- 04All 43 people on board survived the excursion.
Safety Actions & Advisories
Operational Safety Review
Following the accident, emphasis was placed on flight crew training regarding stabilized approach criteria and the hazards of landing on water-contaminated runways. Airport authorities at Sylhet also reviewed runway drainage and friction monitoring procedures during the monsoon season.
