RIN 2120-AA64

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt 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 
proposed AD would require inspecting the propeller blades and other 
critical propeller parts for wear and mechanical damage. This proposed 
AD results from findings that CSE Aviation failed to perform specific 
inspections and repairs. We are proposing 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: We must receive any comments on this proposed AD by August 15, 
2005.

Discussion

    On October 28 and 29, 2003, an FAA International Field Office 
conducted an audit of Oxford Aviation Services Limited, doing business 
as CSE Aviation. That audit revealed that CSE Aviation was not using 
the latest maintenance manuals to perform inspections and repairs. The 
investigators believe the discrepancies date from about 1998, when CSE 
Aviation stopped updating their internal procedures to reflect the 
latest version of the manufacture's maintenance manuals. The audit also 
showed that CSE Aviation did not perform specific inspections required 
by the maintenance manual. CSE Aviation conducted an internal 
investigation and confirmed that they did not perform many inspections 
and rework procedures such as:
     Removing damage to propeller blade balance holes.
     Shot peening the balance holes as required by the 
manufacturer's maintenance instructions.
    Some of the other findings from the CSE Aviations internal audit 
were:
     Returning propellers to service with hubs involved in 
ground strikes.
     Incomplete or incorrectly completed overhauls of the 
propellers before returning to service,
     Not performing significant inspections or repairs that 
would have required a repair or that would have caused that product to 
be declared unairworthy,
    Service history shows that these types of omissions of inspections 
and repair procedures and improperly returning to service propellers 
with these conditions have resulted in cracked propeller blades and 
hubs. These conditions, if not corrected, could result in a propeller 
blade separating from the hub and loss of control of the airplane.

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 
before further flight a search of aircraft and propeller records to 
determine if the propeller was involved in a ground strike. This 
proposed AD would also require disassembly, cleaning, inspection, and 
repair within the following compliance times:
     Within 10 flight hours (FH) time-in-service (TIS) after 
the effective date of this proposed AD, or 2 years after the effective 
date of the proposed AD, whichever is earlier, if the propeller was 
involved in a ground strike.
     Within 200 FH TIS after the effective date of this 
proposed AD, or 2 years after the effective date of the proposed AD, 
whichever is earlier, if the time-since-overhaul (TSO) of the propeller 
is more than 1,500 FH.
     Within 350 FH TIS after the effective date of this 
proposed AD, or 2 years after the effective date of the proposed AD, 
whichever is earlier, if the TSO of the propeller is more than 1,000 FH 
and fewer than 1,500 FH.
     Within 500 FH TIS after the effective date of this 
proposed AD, or 2 years after the effective date of the proposed AD, 
whichever is earlier, if the TSO of the propeller is 1,000 FH or fewer.

Costs of Compliance

    We estimate that about 389 Hartzell Propeller Inc. HC series 
propellers and about 126 McCauley Propeller Systems controllable 
propellers of the affected design installed on airplanes of U.S. 
registry would be affected by this proposed AD. We also estimate that 
it would 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 would cost about $2,350 per propeller. Based on these figures, we 
estimate the total cost of the proposed 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 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 findings that CSE Aviation failed to 
perform 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.

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
------------------------------------------------------------------------
 If the time-since-overhaul (TSO)     Then perform the requirements of
for the propeller on the effective    paragraph (j) or paragraph (k) of
       date of this AD is--                   this AD within--
------------------------------------------------------------------------
(1) 1,500 FH TSO or more..........  200 FH TIS after the effective date
                                     of this AD, but do not exceed 2
                                     years after the effective date of
                                     this AD.
(2) More than 1,000 FH TSO, but     350 FH TIS after the effective date
 fewer than 1,500 FH TIS.            of this AD, but do not exceed 2
                                     years after the effective date of
                                     this AD.
(3) 1,000 FH TSO or fewer.........  500 FH TIS after the effective date
                                     of this AD, but do not exceed 2
                                     years after the effective date of
                                     this AD.
------------------------------------------------------------------------

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 
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.

[[Page 34724]]

    (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, overhauling a propeller is not 
necessary to comply with the requirements specified in paragraph (j) 
or paragraph (k) of this AD. If you don't overhaul the propeller, 
the TSO doesn't change.

Alternative Methods of Compliance (AMOCs)

    (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.
