"Surprised nobody picked it up, same thing happened to a 757 freighter in 2014, it was updated on AVH yesterday"

The Yakutia 757PCF had the same Precision Conversions STC as the DHL aircraft, both installed by Flightstar at Cecil (the Yakutia a couple of years earlier). The two PCFs were the 22nd and 29th conversions, respectively, under that STC.

The damage sustained was notably similar, too, with the inner lining of the door appearing to have been torn off in the airflow.

The early 747s had cargo doors in which the locking sectors were too thin to prevent the latches from being driven open by the electric motors in the event of an electrical malfunction. The DC-10 had a locking system that lacked strength in some components, which, along with incorrect rigging, allowed the manual lever to be forced closed while the latches were not fully engaged.

Too soon to say what the issue was on this 757.
