These actions are against propeller models returned to service by Southern California Propeller Service. Southern California Propeller Service is not to be confused with propeller repair stations known as California Propeller or as Propeller Service of California. Southern California Propeller Service was issued Air Agency Certificate number of VXSR617L in 1992, which was revoked in June of 1998.

\n```\n\n| | For Hartzell propeller models listed in Table 1 of this Directive, any letter or number (or lack of a letter or number) could appear where open parentheses are shown in the model number. Model numbers could show any combination of letters or numbers where the model number shows parentheses with a series of numbers or letters. |\n| ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| Requirement: | For propeller models listed in Table 1 of this Directive, that have been overhauled since being returned to service by Southern California Propeller Service by an authorized repair station other than Southern California Propeller Service, no further action is required.Perform the following actions in accordance with propeller manufacturer's service documentation:1. Disassemble,2. Clean,3. Inspect for the following:a. Cracks,b. Corrosion or pits,c. Nicks,d. Scratches,e. Blade minimum dimensions,f. Unapproved localized heating of blade,g. Unapproved use of helicoil inserts in actuating pin holes,h. Improperly drilled actuating pin holes,i. Chemical conversion coat or paint or both applied over corrosion,j.
