and another pre-cpl while doing wing-drop (full flap, with power) at 3000' (admittedly no real horizon for that one).
Of course you would have written up that defect in the maintenance or equivalent document
Did you "arrange" the wing-drop by a cunning push on a rudder pedal at the point of stall?
Or did the wing really seriously drop with full flap and power on. For certification requirements, the maximum wing drop permitted during the stall is (I seem to recall) 15 degrees. Any more than that, the aircraft is considered as un-airworthy and should be grounded until the defect is fixed. Usually it is a rigging problem.
Too many instructors/pilots are happy to accept un-airworthy aircraft because they fear writing up a defect will jeopardise their employment. Or they are too casual about reporting defect. It is not enough to verbally tell someone there is a purported defect - there is a legal requirement to record it in writing on the approved maintenance document. It is fact of life that not all aircraft owners are understanding; especially when it comes to paying for additional maintenance beyond the standard schedule
