FURY FABRIC FAILURE
The Isaacs Fury II’S pilot was performing aerobatics when, at the bottom of a loop, he encountered wake turbulence, and the aircraft rolled left. He recovered to wings-level but noted that some fabric had separated from the forward area of the upper left wing. After performing a control check in approach configuration, and despite a marked rolling tendency, the pilot carried out a normal landing, Subsequent inspection by the Light Aircraft Association revealed a failure of the affected wing’s leading edge structure, most likely the result of previous damage which may have been small enough to be missed during preflight checks, and had then progressed during the higher energy aerobatic manoeuvring. The source of this previous damage could not be established. The LAA noted that while the area in question could not be inspected without use of a stepladder, thorough preflight inspections of all aircraft surfaces is extremely important.
