Note 1: The above is not a complete list of aircraft which may contain the affected Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series and HA-A2V20-1B series propellers with aluminum blades because of installation approvals made by, for example, Supplemental Type Certificate or field approval under FAA Form 337 "Major Repair and Alteration." It is the responsibility of the owner, operator, and person returning the aircraft to service to determine if an aircraft has an affected propeller.
Note 2: The parenthesis that appear in the propeller models indicate the presence or absence of additional letter(s) which vary the basic propeller hub model designation. This airworthiness directive is applicable regardless of whether these letters are present or absent on the propeller hub model designation.
Note 3: This AD applies to each propeller identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For propellers that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (g) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance: Required as indicated, unless accomplished previously.
To prevent blade separation due to cracked blades, hubs, or blade clamps, which can result in loss of control of the airplane, accomplish the following:

(1) Initially perform a fluorescent dye penetrant and eddy current inspection of the blade, an optical comparator inspection of the blade retention area, a dye penetrant inspection of the blade internal bearing bore, and a visual and magnetic particle inspection of the blade clamp and of the hub. The initial inspection is required within the following:
(i) 1,000 hours time since new (TSN) for propellers with less than 900 hours TSN on the effective date of this AD, provided that the initial inspections are performed within 60 calendar months TSN or 24 calendar months after the effective date of this AD, whichever calendar time occurs later, or
(ii) 100 hours time in service (TIS) for propellers with 900 or more hours TSN, or unknown TSN, on the effective date of this AD, provided that the initial inspections are performed within 24 calendar months after the effective date of this AD.
(2) Thereafter, perform repetitive fluorescent dye penetrant and eddy current inspection of the blade, an optical comparator inspection of the blade retention area, and a visual and magnetic particle inspection of the blade clamp. The repetitive inspection is required at intervals not to exceed 500 hours TIS or 60 calendar months, whichever occurs first, since last inspection.
(3) Thereafter, perform a repetitive visual and magnetic particle inspection of the hub. This repetitive hub inspection is required at intervals not to exceed 250 hours TIS or 60 calendar months, whichever occurs first, since last inspection.
(4) Thereafter, perform a repetitive dye penetrant inspection of the blade internal bearing bore. This repetitive blade internal bearing bore inspection is required at intervals not to exceed 60 calendar months since last inspection.
(b) On Hartzell propeller models with hub models ( )HC-(A,D)(2,3)(X,V)( )-( ),and HA-A2V20- 1B, except HC-A3VF-7( ), perform initial and repetitive inspections and, if necessary, replace with serviceable parts in accordance with Hartzell SB No. HC-SB-61-217, Revision 1, dated July 11, 1997, as follows:
(1) Initially perform a fluorescent dye penetrant and eddy current inspection of the blade, an optical comparator inspection of the blade retention area, a visual and magnetic particle inspection of the blade clamp, and a dye penetrant inspection of the blade internal bearing bore. The initial inspection is required within the following:
(i) 1,000 hours TSN for propellers with less than 800 hours TSN on the effective date of this AD, provided that the initial inspections are performed within 60 calendar months TSN or 24 calendar months after the effective date of this AD, whichever calendar time occurs later, or
(ii) 200 hours TIS for propellers with 800 or more hours TSN, or unknown TSN, on the effective date of this AD, provided that the initial inspections are performed within 24 calendar months after the effective date of this AD.
(2) Thereafter, perform repetitive fluorescent dye penetrant and eddy current inspection of the blade, an optical comparator inspection of the blade retention area, and a visual and magnetic particle inspection of the blade clamp. The repetitive inspection is required at intervals not to exceed 500 hours TIS or 60 calendar months, whichever occurs first, since last inspection.
(3) Thereafter, perform repetitive dye penetrant inspections of the blade internal bearing bore. This repetitive blade internal bearing bore inspection is required at intervals not to exceed 60 calendar months since last inspection.
(c) On Hartzell propeller models with hub models HC-A3VF-7( ) perform initial and repetitive inspections and, if necessary, replace with serviceable parts in accordance with Hartzell SB No. HC-SB-61-217, Revision 1, dated July 11, 1997, as follows:
(1) Initially perform a fluorescent dye penetrant and eddy current inspection of the blade, an optical comparator inspection of the blade retention area, a visual and magnetic particle inspection of the blade clamp, and a dye penetrant inspection of the blade internal bearing bore. The initial inspection is required within the following:
(i) 3,000 hours TSN for propellers that have never been overhauled and have less than 2,500 hours TSN on the effective date of this AD, provided that the initial inspections are performed within 60 calendar months TSN or 24 calendar months after the effective date of this AD, whichever calendar time occurs later, or
(ii) 3,000 hours TIS since last overhaul for propellers that have been overhauled but have less than 2,500 hours TIS since last overhaul on the effective date of this AD, provided that the initial inspections are performed within 60 calendar months TIS since last overhaul or 24 calendar months after the effective date of this AD, whichever calendar time occurs later, or
(iii) 500 hours TIS, for propellers that have never been overhauled and have 2,500 or more hours TSN on the effective date of this AD, or propellers which have been overhauled and have 2,500 or more hours TIS since last overhaul on the effective date of this AD, or propellers with unknown TSN, provided that the initial inspections are performed within 24 calendar months after the effective date of this AD.
(2) Thereafter, perform repetitive fluorescent dye penetrantand eddy current inspection of the blade, an optical comparator inspection of the blade retention area, and a visual and magnetic particle inspection of the blade clamp. The repetitive inspection is required at intervals not to exceed 3000 hours TIS or 60 calendar months, whichever occurs first, since last inspection.
(3) Thereafter, perform repetitive dye penetrant inspections of the blade internal bearing bore. This repetitive blade internal bearing bore inspection is required at intervals not to exceed 60 calendar months since last inspection.
