The airworthiness directive
55-05-02 HAMILTON STANDARD: Applies to All 43E60 Propellers With 6903 Blades Installed on Lockheed 1049 Series Aircraft Powered by Wright 972TC-18DA Series Engines.
Compliance required as indicated.
Analysis of loadings and stresses in the Hamilton Standard 43E60/6903 propeller when installed as noted has shown that it is desirable to improve the strength characteristics of the propeller barrel assembly by shotpeening the barrel and spider in specified areas, and by substituting stronger barrel bolts. Therefore, in order to preclude any failures from this cause:
At the earliest opportunity, but not later than the first overhaul subsequent to May 1, 1955, accomplish the rework of the hub barrels and spiders, and replace the barrel bolts as specified in Hamilton Standard Service Bulletin No. 316 dated September 10, 1954.
