The AAIB report requires considerable effort to read. However, I commend it to anyone who posts here. Within a host of concluding observations, the AAIB report states:
"Causal factors • The aircraft did not achieve sufficient height at the apex of the accident manoeuvre to complete it before impacting the ground, because the combination of low entry speed and low engine thrust in the upward half of the manoeuvre was insufficient.
• An escape manoeuvre was not carried out, despite the aircraft not achieving the required minimum apex height."
