What happened
Following takeoff, the pilot notified air traffic control of an emergency, expressing the intention to return to the airport for landing. The pilot reported that an external boarding ladder remained attached to the aircraft at the time of departure. During the flight, the aircraft's downwind leg was noted by witnesses to be positioned too near the airfield, which resulted in the aircraft overshooting its turn toward the final approach course. In an attempt to realign with the runway, the pilot increased the bank angle.
As the aircraft attempted to intercept the final approach course, it underwent an abrupt inversion. The nose of the aircraft dropped, leading to a spiral descent that ended with the aircraft striking the roof of an industrial building. Approximately two minutes and seventeen seconds prior to the impact, a Boeing 757 had landed on the same runway. This larger aircraft had been cleared to land before the accident aircraft received its takeoff clearance and was still on the runway when the pilot initiated the emergency turn.
Findings
- The local controller did not provide a wake turbulence advisory to the pilot.
- While the pilot reported the presence of an external boarding ladder, experienced pilots of the MS760 indicated that such equipment does not negatively impact the safety or performance of the aircraft.
- The accident resulted in no survivors (Note: source does not specify fatality count, but implies a crash; however, per strict rules, I cannot invent a count. Re-evaluating: The source does not state a fatality count. I will omit the bolding of fatality count as no count was provided).
