14 CFR Part 39

[Docket No. FAA-2005-20141; Directorate Identifier 2005-NE-01-AD; 
Amendment 39-14836; AD 2006-24-07]

Airworthiness Directives; Hartzell Propeller Inc. Propellers and 
McCauley Propeller Systems Controllable Propellers

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Hartzell Propeller Inc. HC, BHC, and PHC series propellers; and 
McCauley Propeller Systems controllable propellers serviced by Oxford 
Aviation Services Limited, doing business as CSE Aviation, in the 
United Kingdom between September 1998 and October 2003. This AD 
requires inspecting the propeller blades and other critical propeller 
parts for wear and mechanical damage. This AD results from findings 
that CSE Aviation failed to perform some specific inspections and 
repairs. We are issuing this AD to detect unsafe conditions that could 
result in a propeller blade separating from the hub and loss of control 
of the airplane.

DATES: This AD becomes effective Janauary 3, 2007.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in Room PL-401 on the plaza level of the Nassif 
Building, 400 Seventh Street, SW., Washington, DC.

FOR FURTHER INFORMATION CONTACT: Timothy Smyth, Aerospace Engineer, 
Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 
2300 East Devon Avenue, Des Plaines, IL 60018-4696; telephone (847) 
294-7132; fax (847) 294-7834.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to certain Hartzell 
Propeller Inc. HC, BHC, and PHC series propellers; and McCauley 
Propeller Systems controllable propellers serviced by Oxford Aviation 
Services Limited, doing business as CSE Aviation, in the United Kingdom 
between September 1998 and October 2003. We published the proposed AD 
in the Federal Register on June 15, 2005 (70 FR 34714). That action 
proposed to require inspecting the propeller blades and other critical 
propeller parts for wear and mechanical damage.

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 
Facility Docket Offices 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 
Transportation Nassif 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

[[Page 69000]]

development of this AD. We have considered the comments received.

Request To Clarify Reason for the AD

    CSE Aviation requests that we clarify the statement ``This 
(proposed) AD results from findings that CSE Aviation failed to perform 
specific inspections and repairs'', to read ``This (proposed) AD 
results from findings that CSE Aviation failed to perform some specific 
inspections and repairs''. The commenter states that adding this word 
more clearly defines the conditions existing in the field. We agree and 
added the word ``some'' in this sentence of the AD.

Request To Clarify the Discussion

    CSE Aviation requests that we clarify the Discussion paragraph in 
the proposed AD to state the following: ``The investigators believe the 
discrepancies date from about 1998 until November 2003 when CSE 
Aviation stopped updating their internal procedures to reflect the 
latest version of the manufacturers' maintenance manuals. The audit 
also showed that CSE Aviation did not perform some specific inspections 
required by the maintenance manual. CSE Aviation conducted an internal 
investigation and confirmed that they did not perform some inspections 
and rework procedures such as:'' We disagree the discussion paragraph 
needs change. We find it adequate as drafted. We did not change the AD.

Requests To Clarify Costs of Compliance

    CSE Aviation requests that we clarify the Costs of Compliance 
paragraph by specifying that about 49 affected Hartzell propellers and 
about 24 affected McCauley propellers are installed on U.S.-registered 
airplanes. We agree. We changed the Costs of Compliance paragraph in 
the AD to reflect that about 49 affected Hartzell propellers and 24 
affected McCauley propellers are installed on U.S.-registered 
airplanes.
    CSE Aviation also suggests that our estimate for part cost 
replacement of $2,350 per propeller, is too high. They suggest a part 
cost per propeller of $200 per propeller, and suggest that our estimate 
might lead to other repair facilities replacing parts that are 
airworthy. They also suggest that the actual total cost for U.S.-
registered installations is about $62,050, with a total worldwide cost 
of about $437,750. We do not agree. The cost numbers provided by CSE 
Aviation do not include a proper range for defective parts, or include 
improper repairs that might be found during the inspections. We did not 
change the AD.

Request To Clarify the Unsafe Condition Statement

    CSE Aviation requests that we clarify the unsafe condition 
statement to state that we are issuing this AD to detect potentially 
unsafe conditions that could result in a propeller blade separating 
from the hub and loss of control of the airplane. We agree and added 
the word ``potentially'' in this sentence of the AD.

Request To Change Compliance Paragraph (f)

    CSE Aviation requests that we change the words `` FAA-approved'' 
with ``appropriately approved'' in compliance paragraph (f), since the 
affected propeller population is worldwide. We do not agree. Our 
authority to mandate airworthiness actions is limited to FAA-approved 
repair facilities and operators, and not foreign country-approved 
facilities and operators.

Conclusion

    We have carefully reviewed the available data, including the 
comment[s] 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 about 49 Hartzell Propeller Inc. HC series 
propellers and about 24 McCauley Propeller Systems controllable 
propellers of the affected design installed on airplanes of U.S. 
registry will be affected by this AD. We also estimate that it will 
take about 10 work hours per propeller to perform the proposed actions, 
and that the average labor rate is $65 per work hour. Required parts 
will cost about $2,350 per propeller. Based on these figures, we 
estimate the total cost of the AD to U.S. operators to be $1,545,000.

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.

Unsafe Condition

    (d) This AD results from findings that CSE Aviation failed to 
perform some specific inspections and repairs. We are issuing this 
AD to detect potentially unsafe conditions that could result in a 
propeller blade separating from the hub and loss of control of the 
airplane.

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) For propellers listed by SN in Table 1 or Table 2 overhauled 
or repaired by CSE after November 2003, or overhauled by an FAA-
approved propeller repair facility after October 2003, no further 
action is required.

All Propellers Listed by SN in Table 1 or Table 2

    (g) Before further flight, perform a document search of airplane 
and propeller records to determine if the propeller was involved in 
a ground strike.
    (h) If the propeller was involved in a ground strike, perform 
the requirements specified in paragraph (j) or paragraph (k) of this 
AD within 10 flight hours (FH) time-in-service (TIS) after the 
effective date of this AD, or 2 years after the effective date of 
this AD, whichever is earlier.
    (i) For all propellers listed by SN in Table 1 or Table 2 of 
this AD, not involved in a ground strike, use the compliance 
schedule in the following Table 3 to perform the requirements 
specified in paragraph (j) or paragraph (k) of this AD as 
applicable.

                      Table 3.--Compliance Schedule

Hartzell Propellers

    (j) For Hartzell propellers listed by SN in Table 1 of this AD, 
do the following:
    (1) Disassemble the propeller.
    (2) Clean all disassembled propeller parts.
    (3) Perform a visual inspection for the following conditions:
    (i) Wear or damage such as cracks, corrosion, scratches, or 
nicks.
    (ii) Except for blades installed new at the last CSE maintenance 
action, examine for:
    (A) Bent or damaged pitch change knobs.
    (B) Damage in the bore area of the blade shank.
    (C) Damage in the blade balance hole.
    (iii) Damage that indicates a previous ground strike (if 
applicable).
    (iv) Unacceptable wear or damage in areas where shot peening is 
required. It is not necessary to strip the paint and corrosion 
protective coatings from the external surface of the blade. It is 
also not necessary to perform dimensional measurements on the

[[Page 69009]]

external surface of the blade unless there is evidence of damage 
that has occurred since CSE returned the propeller to service.
    (v) Confirm that CSE Aviation correctly performed the repairs 
listed in the manufacturers maintenance manuals. An example of a 
maintenance manual repair is chamfering of the hub grease fitting 
hole on Hartzell ``Y'' shank series propellers.
    (4) Perform all Eddy Current inspections applicable.
    (5) Repair and replace with serviceable parts, as necessary.
    (6) Assemble and test.
    (7) Confirm that hubs affected by AD 2001-23-08 are returned to 
service only on aircraft affected by that AD.

McCauley Propellers

    (k) For McCauley propellers listed by SN in Table 2 of this AD, 
do the following:
    (1) Disassemble the propeller.
    (2) Clean all disassembled propeller parts.
    (3) Perform a visual inspection for the following conditions:
    (i) Wear or damage such as cracks, corrosion, scratches or 
nicks.
    (ii) Damage that indicates a previous ground strike (if 
applicable).
    (iii) Unacceptable wear or damage in areas where shot peening is 
required, paying particular attention to hub internal shot peened 
surfaces and blade shank peening. It is not necessary to strip the 
paint and corrosion protective coatings from the external surface of 
the blade. It is also not necessary to perform dimensional 
measurements on the external surface of the blade unless there is 
evidence of damage that has occurred since CSE returned the 
propeller to service.
    (4) Inspect threaded surfaces of threaded blade shanks with a 
10X magnifying glass for scratches parallel to retention threads in 
the thread root of the first four outboard blade threads. If the 
retention threads are scratched, repair is not allowed.
    (5) Confirm that CSE Aviation correctly performed repairs or 
modifications listed in the manufacturer's maintenance instructions.
    (6) Repair and replace with serviceable parts, as necessary.
    (7) Assemble and test.

Definitions

    (l) For the purposes of this AD:
    (1) Overhauling a propeller is not necessary to comply with the 
requirements specified in paragraph (j) or paragraph (k) of this AD. 
If you do not overhaul the propeller, the TSO does not change.
    (2) Unacceptable wear is wear or damage that can penetrate the 
shotpeen compressive layer.

Alternative Methods of Compliance

    (m) 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.
