AD 2005-18-20

The FAA is adopting a new airworthiness directive (AD) for Goodrich De-icing and Specialty Systems "FASTprop" propeller de- icers, part numbers P4E1188 series, P4E1601 series, P4E2200 series, P4E2271-10, P4E2575-7, P4E2575-10, P4E2598-10, P5855BSW, P6199SW, P6592SW, P6662SW, and P6975-11, installed. This AD requires inspection, repair, or replacement of those "FASTprop" propeller de-icers that fail daily visual checks. This AD results from reports of Goodrich "FASTprop" propeller de-icers becoming loose or debonded, and detaching from propeller blades during operation.

Final rule.

Unsafe Condition

(d) This AD results from reports of Goodrich "FASTprop" propeller de-icers becoming loose or debonded, and detaching from propeller blades during operation. We are issuing this AD to prevent Goodrich "FASTprop" propeller de-icers from detaching from the propeller blade, resulting in damage to the airplane, and possible injury to passengers and crewmembers.

Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.

(f) Properly certificated maintenance personnel must perform the initial inspection required in this AD. Thereafter, the pilot or properly certificated maintenance personnel may perform the repetitive visual check.

Initial Visual Inspection of "FASTprop" Propeller De-Icers

(g) Within 10 hours after the effective date of this AD, inspect the"FASTprop" propeller de-icers. If any "FASTprop" propeller de-icer fails the inspection, then the "FASTprop" de-icer must be repaired or replaced as necessary before the next flight. Use paragraphs 2.A(3) through (5) of the Accomplishment Instructions of Goodrich De-icing and Specialty Systems Alert Service Bulletin (ASB) No. 30-60-00-1, dated November 15, 2004 to do these actions.

Repetitive Visual Inspections of "FASTprop" Propeller De-Icers

(h) After the initial inspection, visually check the "FASTprop" propeller de-icer once per day either during the pilot's first preflight inspection of the day or when maintenance personnel are available. If any "FASTprop" propeller de-icer fails the visual check, then the "FASTprop" de-icer must be inspected, repaired, or replaced as necessary before the next flight. Terminating action is accomplished when the "FASTprop" propeller de-icer is removed and replaced with an approved propeller de-icer. Use paragraph 2.A(2) of the Accomplishment Instructions of Goodrich De-icing and Specialty Systems Alert Service Bulletin (ASB) No. 30- 60-00-1, dated November 15, 2004 to do these actions.

Alternative Methods of Compliance

(i) The Manager, Chicago Aircraft Certification Office, has the authority to approve alternative methods of compliance for this AD if requested using the procedures found in 14 CFR 39.19.

Special Flight Permits

(j) Under 14 CFR part 39.23, we are limiting the special flight permits for this AD by requiring that any propeller found with a loose or debonded "FASTprop" de-icer must have all propeller blade de-icers removed before the flight, to maintain a balanced propeller. Information on removing de-icers can be found in paragraph 1.K.(1) of Goodrich De-icing and Specialty Systems ASB No. 30-60-00-1, dated November 15, 2004.

Related Information

(k) None.

Material Incorporated by Reference

(l) You must use Goodrich De-icing and Specialty Systems Alert Service Bulletin No.30-60-00-1, dated November 15, 2004, to perform the inspections, repairs, and replacements required by this AD. The Director of the Federal Register approved the incorporation by reference of this service bulletin in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

The FAA proposed to amend 14 CFR part 39 with a proposed airworthiness directive (AD). The proposed AD applies to Goodrich De-icing and Specialty Systems "FASTprop" propeller de- icers, part numbers P4E1188 series, P4E1601 series, P4E2200 series, P4E2271-10, P4E2575-7, P4E2575-10, P4E2598-10, P5855BSW, P6199SW, P6592SW, P6662SW, and P6975-11. We published the proposed AD in the Federal Register on April 6, 2005 (70 FR 17361). That action proposed to require inspection, repair, or replacement of those "FASTprop" propeller de-icers that fail visual checks before the first flight each day.

Examining the AD Docket

You may examine the docket that contains the AD, any comments received, and any final disposition in person at the Docket Management System (DMS) Docket Office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5227) is located on the plaza level of the Department of TransportationNassif Building at the street address stated in ADDRESSES. Comments will be available in the AD docket shortly after the DMS receives them.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the one comment received.

The commenter states that we need to clarify the compliance section, and requests that any pilot be able to make required logbook entries after the visual check of propeller de-icers regardless of how the airplane is operated, whether under 14 CFR part 91, part 135, or part 121. The commenter interprets Goodrich De-icing and Specialty Systems Alert Service Bulletin (ASB) No. 30-60-00-1, dated November 15, 2004, as only allowing private pilots operating under 14 CFR part 91 to make the required logbook entries.

We agree that we need to clarify the compliance section. Accordingly, we added the following statement to the compliance section of this AD: "Properly certificated maintenance personnelmust perform the initial inspection required in this AD. Thereafter, the pilot or properly certificated maintenance personnel may perform the repetitive visual check."

Conclusion

We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

We estimate that 3,400 Goodrich propeller de-icers are installed on airplanes of U.S. registry and will be affected by this AD. We also estimate that it will take about:

Two minutes per propeller blade to perform the preflight visual check; and

Five minutes per propeller blade to perform the inspection of de-icers that fail the visual check; and

One-half work hour to replace a propeller de-icer.

The average labor rate is $65 per work hour. Required parts will cost about $110.00 per replacement propeller de-icer. The manufacturer has advised us that replacement de-icers will be provided at no cost to the operators. Based on these figures, not including free de-icer hardware supplied by the manufacturer, we estimate the total cost of the AD to U.S. operators to be $510,240.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, "General requirements." Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) Is not a "significant regulatory action" under Executive Order 12866;

(2) Is not a "significant rule" under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.
