The pilot replied: "Negative, just avoided a patch there, but back on heading five thousand feet."
The plane then "climbed rapidly" to about 2,300 ft before it crashed into the sea breaking into three pieces at around 8.16pm on Jan 21.
The aircraft, which was built in 1984, has papers held by a company based in Norfolk, Southern Aircraft Consultancy.
Ibbotson, who had previously written on Facebook that he was "rusty", had reportedly filled out forms incorrectly before take off. On one, he was said to have written N246DB instead of N264DB.
He is also said to have been qualified to fly at night only if conditions were clear without any bad weather.
