AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

A number of propeller blade outer sleeves 

have been found with cracks since 1996. 

Testing has shown that blade retention 

integrity is not affected by this cracking. 

However, this condition, if not detected and 

corrected, can lead to blade counterweight 

release, possibly resulting in damage to the 

aircraft and injury to occupants or persons on 

the ground. 

We are issuing this AD to prevent blade 

counterweight release, which could 

result in injury or damage to the 

airplane. 

DATES: This AD becomes effective 

April 7, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) and a supplemental 

NPRM to amend 14 CFR part 39 to 

include an AD that would apply to the 

specified products. That NPRM was 

published in the Federal Register on 

June 30, 2008 (73 FR 36819), and the 

supplemental NPRM was published in 

the Federal Register on May 18, 2009 

(74 FR 23131). Those NPRMs proposed 

to correct an unsafe condition for the 

specified products. The MCAI states 

that: 

A number of propeller blade outer sleeves 

have been found with cracks since 1996. 

Testing has shown that blade retention 

integrity is not affected by this cracking. 

However, this condition, if not detected and 

corrected, can lead to blade counterweight 

release, possibly resulting in damage to the 

aircraft and injury to occupants or persons on 

the ground. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

responded to the comments received on 

the NPRM, in the supplemental NPRM. 

We considered the one comment 

received on the supplemental NPRM, as 

follows: 

Claim That Tracking of Individual 

Propeller Blades Is Not Required 

One commenter, a private citizen, 

states that if the proposed AD was 

rewritten against the propeller 

assembly, instead of the propeller 

blades, then all four propeller blades are 

inspected at the same time, and tracking 

of individual propeller blades is not 

required. Also, because the propeller 

blades could be moved from propeller to 

propeller, a requirement to inspect all 

four propeller blades at the time the 

propeller is assembled, ‘‘zeroing out’’ the 

inspection, would prevent any propeller 

blade in the assembly from exceeding its 

inspection interval. 

We do not agree. Since the propeller 

blade log cards are with the propeller 

blades, it is appropriate in writing the 

AD against the propeller blades; not the 

propeller assembly. Also, since the AD 

is related to propeller blade inspections, 

and propeller assembly total time is 

independent of propeller blade total 

time, tracking propeller assembly time 

could result in a propeller blade 

exceeding the 1,600 flight hour or 

15,000 flight hour time-in-service 

inspection interval. We did not change 

the AD. 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

292 propellers installed on airplanes of 

U.S. registry. We also estimate that it 

will take 0.5 work-hour per propeller to 

visually inspect for cracks. The average 

labor rate is $80 per work-hour. Based 

on these figures, we estimate the cost of 

the AD on U.S. operators to be $11,680.

9516 Federal Register / Vol. 75, No. 41 / Wednesday, March 3, 2010 / Rules and Regulations 

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 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 this AD: 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 adding 

the following new AD: 

2010–05–09 Dowty Propellers: Amendment 

39–16219. Docket No. FAA–2008–0545; 

Directorate Identifier 2008–NE–16–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 7, 2010. 

Affected ADs 

(b) None. 

(c) This AD applies to Dowty Propellers 

Models R354/4–123–F/13, R354/4–123–F/20, 

R375/4–123–F/21, R389/4–123–F/25, R389/ 

4–123–F/26, and R390/4–123–F/27 

propellers. These propellers are installed on, 

but not limited to, Saab AB, Saab 

Aerosystems SF340A and SAAB SF340B 

airplanes. 

Reason 

(d) European Aviation Safety Agency 

(EASA) AD No. 2008–0033, dated 

February 19, 2008, states: 

A number of propeller blade outer sleeves 

have been found with cracks since 1996. 

Testing has shown that blade retention 

integrity is not affected by this cracking. 

However, this condition, if not detected and 

corrected, can lead to blade counterweight 

release, possibly resulting in damage to the 

aircraft and injury to occupants or persons on 

the ground. 

This AD requires initial and repetitive 

visual inspections of propeller blade root 

outer sleeves for cracks, and removal before 

further flight of propeller blades with cracked 

blade root outer sleeves. We are issuing this 

AD to prevent blade counterweight release, 

which could result in injury or damage to the 

airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

Propeller Blade Root Outer Sleeve Visual 

Inspections 

(1) At the next 1,600 flight hours (FH) 

aircraft check after the effective date of this 

AD, or, after any blade accumulates 15,000 

FH time-in-service, whichever occurs later, 

visually inspect all propeller blade root outer 

sleeves for cracks. 

(2) Thereafter, at intervals not to exceed 

1,600 FH, visually inspect all propeller blade 

root outer sleeves for cracks. 

(3) Before further flight, remove any 

propeller blades found with cracked root 

outer sleeves during the visual inspections in 

paragraphs (e)(1) and (e)(2) of this AD. 

FAA AD Differences 

(f) None. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Boston Aircraft 

Certification Office, FAA, Engine and 

Propeller Directorate, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19.
