Air Force Upgrades War-Tested C-130

Giving the platform new radios, digital avionics, collision avoidance technology and reinforced “wing-boxes,” service officials said.

The Air Force remains vigilant about its C-130 fleet to ensure the airframes, wingboxes, avionics and communication systems remain safe and operational well into the 2030s and beyond. This is particularly true of the older 1980s-era C-130Hs, Air Force developers explained.

“The thing that causes the greatest risk to the airplane is the life of the wing. We monitor the wing of the aircraft and as the wings get past their service, life we bring the airplanes back in and bring in new structures — with the primary focus being the center wingbox which is the area where the wings mount to the fuselage,”Col. Robert Toth, Chief of Tactical Aircraft, Special Operations and Combat Search and Rescue Division, told Scout Warrior in an interview last year.

As for when a C-130 is in need of a maintenance upgrade to preserve and maintain service life, the Air Force uses an assessment metric referred to as “equivalent baseline hours.” The wing-boxes are changed once the aircraft reaches a certain “severity factor” in its operational service time. This is necessary because the wear and tear or impact of missions upon and airplane can vary greatly depending upon a range of factors such as the altitude at which a plane is flying, Toth said.

“Low-level flight may be three to four times the severity factor of flying at a higher level,” he said.

Also, by January of 2020 the entire fleet of C-130s will need to comply with an FAA mandate and be equipped with systems that will relay aircraft position to a greater fidelity back and forth between the airplane and the air traffic management authorities, he added. This will allow them to sequence more aircraft closer together and enhance an ability to move commerce.

Avionics Modernization Program, Increment 1 involves adding new 8.33 radios to the aircraft to improve communication along with initiatives to upgrade cockpit voice recorders and digital data recorders. C-130s will also receive new collision-avoidance technology designed to prevent the planes from hitting terrain or colliding with one another mid-air. Inc. 1 is currently ongoing and is slated to complete by 2019.
