Most C-130's and Electras (yeah, we still get a few L188s) that I see around here (BNA) are equipped with 4-blade Aeroproducts propellors. As an aside, up until about three years ago the TNANG 118th Tactical Airlift Wing had the USAF's oldest flying C-130 (an ancient A model with 3-blade Curtiss (I think) props.) Apparently the Navy, sometime during the production life of the P-3, must have changed prop suppliers to Ham Standard. On a related note, in a recent Airliners article on Reeve Aleutian Airways Electra operations mention was made about spare part supplies running out for rebuilding Aeroproducts props. They stated that it would be too expensive to convert to Ham Standards. Zantop at one time ran an Electra into here with Ham Standards, so evidently someone has a STC for the conversion.
