The Load 15 Report clearly shows the exceedence so I wonder then, what maintenance procedure permitted the aircraft to be dispatched again after a 4.86g landing?
The report says that neither the captain nor the line mechanics at Ponta Delgada knew how to interpret the data in the load report... then based on just a visual inspection, they decided that the aircraft was OK to return to Lisbon, and wrote nothing on the technical log. After arriving at Lisbon, a little past midnight, the captain asked for help to other mechanics to interpret the load report, but they were also unable to do so, and decided to pass the question onto the next shift. The next shift would start at 8 a.m., but the plane was scheduled to take of to another flight before 7 a.m., and unwillingness to delay it, resulted in the severity of the hard landing being only accessed the following night, when the aircraft would undergo a scheduled A check.
