The preliminary report, which was released on Monday, showed that although the chopper had a long-range extender fuel system, it did not have the capacity to dump fuel.
According to the report, the chopper was refuelled to full capacity on August 27, a day before the crash.
After refuelling, 10 minutes of engine run and 20 minutes of test flight were also said to have been carried out on the helicopter in Port Harcourt.
“The helicopter was fitted with a range-extender fuel system. No fuel jettisoning capability on this helicopter. The helicopter has an endurance of 3:24h. The operational flight plan filed by the pilot indicated an endurance of 3:15 h and an estimated flight time of 2:45h,” the report read.

“Post occurrence examination revealed that the fuel tanks were empty. The mast and main rotor blades were found intact during the post-crash inspection.”
The report also revealed that the pilot’s last medical examination was valid until August 6, 2020.
The AIB said it did not find evidence that an application for the exemption provided by the All Operators’ Letter (AOL) DG02020 had been submitted to the Nigerian Civil Aviation Authority (NCAA).
The pilot’s last proficiency check was also reported to have been valid till August 24, 2020, and there was no evidence to show that an application for the exemption provided by the AIL DG018/ 20 had been submitted to the NCAA.
