Airworthiness Directives; Goodrich De-icing and Specialty Systems 
``FASTprop'' Propeller De-icers

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt 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 proposed AD would 
require inspection, repair, or replacement of those ``FASTprop'' 
propeller de-icers that fail visual checks before the first flight each 
day. This proposed AD results from reports of Goodrich ``FASTprop'' 
propeller de-icers becoming loose or debonded, and detaching from 
propeller blades during operation. We are proposing 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 the passengers and crewmembers.

DATES: We must receive any comments on this proposed AD by May 6, 2005.

proposed AD.

Discussion

    In September of 2004, we became aware of reports of about 200 
Goodrich De-icing and Specialty Systems ``FASTprop'' propeller de-icers 
found debonded, loose, or detached from propeller blades during 
operation. The manufacturer is still investigating to determine the 
exact cause of this potential unsafe condition. This condition, if not 
corrected, could result in propeller de-icers detaching from propeller 
blades, resulting in damage to the airplane and possible injury to the 
passengers and crewmembers.

Relevant Service Information

    We have reviewed and approved the technical contents of Goodrich 
De-icing and Specialty Systems Alert Service Bulletin No. 30-60-00-1, 
dated November 15, 2004, that describes procedures for visual checks of 
``FASTprop'' propeller de-icers before the first flight each day, and 
inspection, repair, or replacement of those propeller de-icers if 
necessary.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other products 
of this same type design. We are proposing this AD, which would require 
inspection, repair, or replacement before further flight, of Goodrich 
``FASTprop'' propeller de-icers if they fail the visual check before 
the first flight each day. The proposed AD would require you to use the 
service information described previously to perform these actions.

Interim Action

    These actions are interim actions and we may take further 
rulemaking actions in the future.

Costs of Compliance

    We estimate that 3,400 Goodrich propeller de-icers are installed on 
airplanes of U.S. registry and would be affected by this proposed AD. 
We also estimate that it would take about 2 minutes per propeller blade 
to perform the proposed preflight visual check, about 5 minutes per 
propeller blade to perform the proposed inspection of de-icers that 
fail the visual check, and about 0.5 work hour to replace a propeller 
de-icer. The average labor rate is $65 per work hour. Required parts 
would 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, we estimate the 
total cost of the proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Would 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 proposal and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.

------------------------------------------------------------------------

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.

[[Page 17366]]

Initial Visual Inspection of ``FASTprop'' Propeller De-icers

    (f) During the next preflight or 100-hour inspection, whichever 
occurs first, after the effective date of this AD, visually check 
the ``FASTprop'' propeller de-icers. 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. Use paragraph 2.A 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

    (g) If after the effective date of this AD, any ``FASTprop'' 
propeller de-icer found to have lifting, looseness, trapped air 
(bubbles) under the de-icer, debonding, or deteriorated edge sealer 
during the pilot's first preflight inspection of the day must be 
inspected, repaired, or replaced as necessary before the next 
flight. Use paragraph 2.A 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

    (h) 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

    (i) 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 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.
