C-130/L100 Hercules
Outer Wing Improvement Program (OWIP)

Spar Aerospace Limited (Spar) has developed an Outer Wing Improvement Program (OWIP) to extend the structural fatigue service of original production outer wings on the C-130/L100 Hercules.

The structural fatigue service of C-130/L100 original production outer wings is 12,500 hours. When C-130/L100 operators reach this milestone they face the expense of replacing the outer wings. OWIP more than doubles the aircraft’s outer wing fatigue service by installing preventative modifications.

OWIP was designed to ensure the structural integrity of the outer wings and is focused on their primary structure — the outer wing spar box. The design philosophy is based on refurbishment rather than rebuilding. It ensures that the fatigue service of the wings can be safely extended and provides a cost-effective option to the operator of the C-130/L100 aircraft.

Spar has successfully installed the OWIP modification for both commercial and military operators of the Hercules aircraft, including the fleet of Canadian Air Force CC130 aircraft whose outer wings had reached their fatigue service of 12,500 hours. The installation of the Spar outer wing modification has allowed these aircraft to fly 25,000 hours, double their production-designed fatigue service.
