Airworthiness Directives; Hartzell Propeller Inc. Model HD-E6C-
3B/E13890K Propellers

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), that 
is applicable to Hartzell Propeller Inc. model HD-E6C-3B/E13890K 
propellers with certain serial numbers of model D-1199-2 propeller 
control units (PCU's) installed. This amendment requires initial and 
repetitive inspections for below-limit propeller flight idle blade 
angles, and, as a terminating action, removal of the affected PCU's 
from service and performance of a complete Major Periodic Inspection 
(overhaul) when the applicable time-since-new or time-since-overhaul 
limit is reached, or when any flight idle blade angle is below limits. 
This amendment is prompted by a review by Hartzell Propeller Inc. of 
the model D-1199-2 PCU overhaul procedures, that revealed several 
dimensional checks and a nondestructive evaluation were not performed 
on certain serial number PCU's during a Major Periodic Inspection 
(overhaul). The overhaul procedures are required to comply with the 
Airworthiness Limitation PCU Major Periodic Inspection (overhaul) 
directive. The actions specified by this AD are intended to prevent 
below-limit flight idle propeller blade angles that, if not corrected, 
could result in degraded aircraft performance and control.

DATES: Effective April 4, 2003. The incorporation by reference of 
certain publications listed in the regulations is approved by the 
Director of the Federal Register as of April 4, 2003.

ADDRESSES: The service information referenced in this AD may be 
obtained from Hartzell Propeller Inc. Technical Publications 
Department, One Propeller Place, Piqua, OH 45356; telephone (937) 778-
4200; fax (937) 778-4391. This information may be examined, by 
appointment, at the Federal Aviation Administration (FAA), New England 
Region, Office of the Regional Counsel, 12 New England Executive Park, 
Burlington, MA; or at the Office of the Federal Register, 800 North 
Capitol Street, NW., suite 700, Washington, DC.

7031, fax (847) 294-7834.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an AD that is 
applicable to Hartzell Propeller Inc. model HD-E6C-3B/E13890K 
propellers with certain serial numbers of model D-1199-2 PCU's 
installed was published in the Federal Register on October 18, 2002 (67 
FR 64322). That action proposed to require initial and repetitive 
inspections for below-limit propeller flight idle blade angles, and, as 
a terminating action, removal of the affected PCU's from service and 
performance of a complete Major Periodic Inspection (overhaul) when the 
applicable time-since-new or time-since-overhaul limit is reached, or 
when any flight idle blade angle is below limits in accordance with 
Hartzell Service Bulletin No. (SB) HD-SB-61-025, dated November 7, 
2002, or SB No. HD-SB-61-025, Revision 1, dated December 20, 2000.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposal or the FAA's determination of the cost to the public. The FAA 
has determined that air safety and the public interest require the 
adoption of the rule as proposed.

Economic Analysis

    There are approximately 78 Hartzell Propeller Inc. model D-1199-2 
PCU's of the affected design in the worldwide fleet. The FAA estimates 
that 50 PCU's installed on airplanes of U.S. registry would be affected 
by this AD. The FAA also estimates that it would take approximately 1.5 
work hours per propeller to perform the initial inspections, 25 work 
hours per propeller to perform the PCU replacements, and that the 
average labor rate is $60 per work hour. Required parts would cost 
approximately $7,321 per propeller. Based on these figures, the total 
cost of initial inspections of this AD to U.S. operators is estimated 
to be $4,500, and the total cost of replacement of the affected PCU's 
to U.S. operators is estimated to be $441,050.

Regulatory Analysis

    This final rule does not have federalism implications, as defined 
in Executive Order 13132, because it 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. Accordingly, 
the FAA has not consulted with state authorities prior to publication 
of this final rule.
    For the reasons discussed above, I certify that this action (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) 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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
by contacting the Rules Docket at the location provided under the 
caption ADDRESSES.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. Section 39.13 is amended by adding a new airworthiness directive 
to read as follows:

2003-04-22 Hartzell Propeller Inc.: Amendment 39-13071. Docket No. 
2000-NE-60-AD.

    Applicability: This airworthiness directive (AD) is applicable 
to Hartzell Propeller Inc. model HD-E6C-3B/E13890K propellers with 
certain serial numbers of model D-1199-2 Propeller Control Units 
(PCU's) installed, as listed in Table 1 of this AD. These propellers 
are installed on, but not limited to Fairchild Dornier GmbH 328-100 
series airplanes.

    Note 1: This airworthiness directive (AD) applies to each 
propeller identified in the preceding applicability provision, 
regardless of whether it has been modified, altered, or repaired in 
the area subject to the requirements of this AD. For propellers that 
have been modified, altered, or repaired so that the performance of 
the requirements of this AD is affected, the owner/operator must 
request approval for an alternative method of compliance in 
accordance with paragraph (g) of this AD. The request should include 
an assessment of the effect of the modification, alteration, or 
repair on the unsafe condition addressed by this AD; and, if the 
unsafe condition has not been eliminated, the request should include 
specific proposed actions to address it.

    Compliance: Compliance with this AD is required as indicated, 
unless already done.
    To prevent below-limit flight idle propeller blade angles that, 
if not corrected, could result in degraded aircraft performance and 
control, do the following:
