Vol. 26, No. 2, April - June 1999 The new maintenance system for the C-130J is as advanced as anything on the airplane. As detailed in the accompanying article, the Ground Based CONTENTS Data System, which includes items such as the Ground Maintenance System, 2 Focal Point Portable Maintenance Aid, and Removable Memory Modules, will make sig- Bill F.

Customer Operations and Support 3 Maintenance for a New Hercules To assure operational Hercules organizations can take full advantage of all Scott Brinegar the new systems the “J” offers, this new airplane is backed up by a top-notch Field Service Representative support organization. This is where the new Customer Operations and Support organization comes into play. As mentioned by Terry Graham in the 8 Honduras Relief Missions: The C-130J in Action last issue of Service News, Lockheed Martin has reorganized product support functions into Customer Operations and Support. The primary purpose of 10 C-130/Hercules Aircraft and Y2K this organization is to help each of our customers get the most out of their Ed Carroll aircraft. This includes not only the new “J”, but also the previous models.
