Narrative:
During operations check of flaps/slats, flaps were lowered on to a ladder causing a 2 inch dent/crack on left inboard trailing edge flap, the honeycomb material was sealed with pro seal and hi speed tape installed per maintenance control and srm 57. I was not sure that the above temperature repair was legal, but followed maintenance control's instruction by installing the high speed tape, the aircraft was released for positioning flight.
