Jim Burt is correct.

The last "remanufactured" OH-58Ds left Bell about 7 years ago. Most of
the remanufactured Kiowas left Bell about 15 to 20 years ago. Unlike
Bell H-1s and Cobras which can be with remanufactured over and over
(and over), light helicopters like the OH-58 are not as robust. If
they were, they would be as heavy as a H-1.

Take care,
