                   a. A Suffix: "A" suffix hubs not listed by serial number in Table 1 shall be removed from service in accordance with Hartzell SB HC-SB-61-227 Revision 5 dated September 28, 2006 or later FAA approved revision.

                   b. Table 1:  All hubs listed by serial number in Table 1 shall be removed from service in accordance with Hartzell SB HC-SB-61-227 Revision 5 dated September 28, 2006 or later FAA approved revision.

              Propeller hubs removed from service as a result of this Directive shall have the hub serial number and type certificate number permanently removed.

Compliance:     1. Eddy Current Inspection:

                  a. No Suffix: Unless previously carried out; within 50 propeller hours Time In Service (TIS) from the effective date of this Directive.

                  b. E Suffix: At intervals not to exceed 100 propeller hours TIS from the last ECI.

                  c. Table 1: Unless previously carried out within 50 propeller hours TIS, and thereafter at intervals not to exceed 100 hours from the last ECI.
                2. Hub Replacement:

                  a. A Suffix: Propellers with the suffix "A" at the end of the hub serial number excluding those S/N's listed in Table 1 of applicability, are to be replaced as follows:

                     i. PA-32 and BN-2 series aircraft; at next propeller overhaul but no later than 2000 hours propeller TIS or 31 December 2005, whichever comes first.

                     ii. Aircraft certified in the aerobatic category or aircraft routinely exposed to aerobatic manoeuvres; at next propeller overhaul but not to exceed 1000 propeller hours TIS or 31 December 2005, whichever comes first.  For propeller hubs exceeding 1000 hours time in service as of the original effective date of this Directive, remove from service within 15 propeller hours TIS.

                     iii. Agricultural aircraft;
