This standard is supplementary to AS 41 'Propeller Shaft Ends, Single Rotation', and AS 91 'Propeller Shaft Ends, Dual Rotation (Propeller Supplied Bearing)'. It is applicable to all engines that incorporate two-speed propeller reduction gears.
This Aerospace Information Report (AIR) is written as an aid for locating and identifying various fitting designs and configurations that are designated as standard parts.
This standard establishes the basic triangular profile for the MJB thread form, the design profiles, standard pitches, tolerance classes, formulae for tolerances and dimensions, tolerance tables, and a system of designations. Because of the specialized application for buttress threads, no preferred diameter-pitch series have been established for this standard and each application will require use of the thread formulae for dimensions and related tolerances given herein for deriving the thread dimensional requirements.

This standard provides a method for the application of surface roughness control primarily to aircraft engine and propeller parts. ASA publication B46 may be used to supplement the information compiled herein. This standard contains a summary of the information in ASA B46 publication plus other information which has been compiled from current manufacturing practice.
