AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are revising airworthiness 

directive (AD) 2008–21–07 for certain 

Dowty Propellers model R408/6–123–F/ 

17 propellers. AD 2008–21–07 required 

initial and repetitive inspections of the 

blade bonded metallic leading edge (L/ 

E) guards for correct bonding until they 

accumulate more than 1,200 flight hours 

(FH) time-in-service. This AD requires 

the same inspection and replacement 

requirements of AD 2008–21–07. This 

AD also provides an optional 

terminating action to those 

requirements. This AD was prompted by 

updated service bulletins that identify 

terminating action to the requirements 

of AD 2008–21–07. We are issuing this 

AD to prevent the loss of the bonded 

metallic L/E guard of the propeller, 

which could result in damage to the 

propeller or to the airplane, or injury to 

personnel. 

DATES: This AD is effective July 15, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 15, 2014. 

The Director of the Federal Register 

approved the incorporation by reference

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to revise AD 2008–21–07, 

Amendment 39–15691 (73 FR 61346, 

October 16, 2008), (‘‘AD 2008–21–07’’). 

AD 2008–21–07 applied to the specified 

products. The NPRM published in the 

Federal Register on December 26, 2013 

(78 FR 78290). The NPRM proposed to 

continue to require the inspection and 

replacement requirements of AD 2008– 

21–07 and provide an optional 

terminating action to those 

requirements. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 78290, December 26, 2013). Since we 

issued the NPRM we received 

information that propeller blade, part 

number (P/N) 697071278–18, has not 

been implemented and that no parts 

were manufactured using this P/N. We 

removed propeller blade, P/N 

697071278–18, from this AD. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of 

this AD. 

Costs of Compliance 

We estimate that this AD affects 174 

propellers installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 4 hours per propeller to 

comply with this AD. The average labor 

rate is $85 per hour. Required parts cost 

about $352 per propeller. Based on 

these figures, we estimate the cost of 

this AD to U.S. operators is $120,408. 

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 

This AD will not have federalism 

implications under Executive Order 


emcdonald on DSK67QTVN1PROD with RULES
Federal Register / Vol. 79, No. 111 / Tuesday, June 10, 2014 / Rules and Regulations 33049 

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), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA 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. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing airworthiness directive (AD) 

2008–21–07, Amendment 39–15691 (73 

FR 61346, October 16, 2008), and 

adding the following new AD: 

AD 2008–21–07R1 Dowty Propellers 

Propellers: Amendment 39–17831; 

Docket No. FAA–2008–1088; Directorate 

Identifier 2008–NE–15–AD. 

(a) Effective Date 

This AD is effective July 15, 2014. 

(b) Affected ADs 

This AD replaces AD 2008–21–07, 

Amendment 39–15691 (73 FR 61346, October 

16, 2008). 

(c) Applicability 

This AD applies to Dowty Propellers model 

R408/6–123–F/17 propellers with blades, 

part numbers 697071200–18, 697071210–18, 

697071227–18, 697071240–18, 697071245– 

18, or 697071257–18, installed.

This AD was prompted by updated service 

bulletins that identify terminating action to 

the requirements of AD 2008–21–07 (73 FR 

61346, October 16, 2008). We are issuing this 

AD to prevent the loss of the bonded metallic 

leading edge (L/E) guard of the propeller, 

which could result in damage to the 

propeller or to the airplane, or injury to 

personnel. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Within the next 50 flight hours (FH) or 

within 30 days after the effective date of this 

AD, whichever occurs first, inspect all 

affected blade assemblies where the bonded 

metallic L/E guard has accumulated 1,200 FH 

time-in-service or less since installation, in 

accordance with the instructions of Dowty 

Propellers Alert Service Bulletin (ASB) No. 

D8400–61–A69, Revision 1, dated September 

18, 2007. 

(2) Within 50 FH or 30 days, whichever 

occurs first, after installing a replacement 

blade, inspect the affected blade assembly 

where the bonded metallic L/E guard has 

accumulated 1,200 FH time-in-service or less 

since installation, in accordance with the 

instructions of Dowty Propellers ASB No. 

D8400–61–A69, Revision 1, dated September 

18, 2007. 

(3) Thereafter, at intervals not to exceed 

100 FH, repeat the inspection of the affected 

blade assemblies in accordance with the 

instructions of Dowty Propellers ASB No. 

D8400–61–A69, Revision 1, dated September 

18, 2007, until the blade bonded metallic L/ 

E guard has accumulated more than 1,200 FH 

time-in-service since installation. 

(4) If, during any of the inspections 

required by this AD, disbonding is found, 

apply the criteria in Appendix A of Dowty 

Propellers ASB No. D8400–61–A69, Revision 

1, dated September 18, 2007 and, within the 

associated time period, repair or replace the 

affected blade assembly in accordance with 

Dowty Propellers ASB No. D8400–61–A69, 

Revision 1, dated September 18, 2007. 

(5) Blades that were repaired within the 

first 101.6 mm (4.0 inches) of the tip of the 

blade as specified in Appendix D of Dowty 

Propellers ASB No. D8400–61–A69, Revision 

1, dated September 18, 2007, are eligible to 

continue in service for another 500 FH after 

accomplishment of the repair. Repair does 

not terminate the repetitive inspection 

requirements of paragraph (e)(3) of this AD. 

(f) Optional Terminating Action 

As optional terminating action to the 

repetitive inspection requirements of 

paragraph (e)(3) of this AD, modify the 

affected propeller using Dowty Propellers
