The FAA is adopting a new airworthiness directive (AD) for certain Hartzell Propeller Inc. propellers. This AD requires inspecting the propeller blades and other critical propeller parts for corrosion and mechanical damage. This AD results from two events where a "Z- shank" blade failed and separated and the results of teardown inspections that detected corrosion in the blade bore. We are issuing this AD to detect corrosion and mechanical damage that can cause failure of a propeller, which could result in loss of control of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
We recommend that you comply with the inspection requirements of this AD, if you have an aircraft with an experimental type certificate, and you have a propeller hub model listed in this AD installed on that aircraft.
If the time-since-overhaul (TSO) of the propeller is 10 years or fewer on the effective date of this AD, no further action is required.
(h) If the propeller assembly was inspected using Hartzell Service Bulletin (SB) No. HC-SB-61-136, Revision I, dated April 25, 2003; SB No. 136, Revision H, dated March 12, 1993; or SB No. 136, Revision G, dated November 15, 1991; no further action is required.
(i) If the TSO of the propeller assembly is more than 10 years on the effective date of this AD, or if the TSO is unknown, or if the propeller has not complied with Hartzell SB No. HC-SB-61-136, Revision I, dated April 25, 2003; or SB No. 136, Revision H, dated March 12, 1993; or SB No. 136, Revision G, dated November 15, 1991; perform the actions specified in Table 3 of this AD. Use the compliance times specified in Table 3 of this AD. Information on inspecting the propeller assembly for cracks, corrosion or pits, nicks, scratches, wear, blade minimum dimensions, and damage in the blade balance bore can be found in the applicable Hartzell maintenance manuals.
| If the TSO of the propeller assembly on the effective date of this AD is... | Then... | Perform the the inspection... |
|---|---|---|
| (1) More 25 years or the TSO is not known | (a) Disassemble and clean the propeller assembly (b) Perform visual and nondestructive inspections of propeller components for cracks, corrosion or pits, nicks, scratches, wear, blade minimum dimensions, and damage in the blade balance hole (c) Inspect and rework the propeller blade bore. Use 3.A. of the Accomplishment instructions of Hartzell SB No. HC-SB-61-136, Revision I, dated April 26, 2003 (d) Repair and replace with serviceable parts, as necessary. (e) Reassemble and test. | Within 12 months after the effective date of this AD. |
| (2) Twenty-one to 25 years | (a) Disassemble and clean the propeller assembly (b) Perform visual and nondestructive inspections of propeller components for cracks, corrosion or pits, nicks, scratches, wear, blade minimum dimensions, and damage in the blade balance hole (c) Inspect and rework the propeller blade bore. Use 3.A. of the Accomplishment instructions of Hartzell SB No. HC-SB-61-136, Revision I, dated April 26, 2003 (d) Repair and replace with serviceable parts, as necessary. (e) Reassemble and test. | Within 18 months after the effective date of this AD. |
| (3) Sixteen to 20 years | (a) Disassemble and clean the propeller assembly (b) Perform visual and nondestructive inspections of propeller components for cracks, corrosion or pits, nicks, scratches, wear, blade minimum dimensions, and damage in the blade balance hole (c) Inspect and rework the propeller blade bore. Use 3.A. of the Accomplishment instructions of Hartzell SB No. HC-SB-61-136, Revision I, dated April 26, 2003 (d) Repair and replace with serviceable parts, as necessary. (e) Reassemble and test. | Within 24 months after the effective date of this AD. |
| (4) Eleven to 15 years | (a) Disassemble and clean the propeller assembly (b) Perform visual and nondestructive inspections of propeller components for cracks, corrosion or pits, nicks, scratches, wear, blade minimum dimensions, and damage in the blade balance hole (c) Inspect and rework the propeller blade bore. Use 3.A. of the Accomplishment instructions of Hartzell SB No. HC-SB-61-136, Revision I, dated April 26, 2003 (d) Repair and replace with serviceable parts, as necessary. (e) Reassemble and test. | Within 36 months after the effective date of this AD. |
Performing an overhaul of the propeller assembly after the effective date of this AD constitutes compliance with the requirements specified in this AD. The latest applicable Maintenance Manuals issued by Hartzell Propeller Inc. contain information on overhauling a propeller assembly.
(k) The time-since-overhaul only changes if you overhaul the propeller assembly while performing the requirements specified in this AD.
Report inspection results to the Manager, Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 2300 East Devon Ave, Des Plaines, IL 60018, within 15 working days of the inspection. The Office of Management and Budget (OMB) approved the reporting requirements and assigned OMB control number 2120-0056.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
