Airworthiness Directives; McCauley

L106FA Propellers 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: This supplemental NPRM 

revises an earlier proposed 

airworthiness directive (AD), for 

McCauley Propeller Systems model 

4HFR34C653/L106FA propellers. That 

proposed AD would have required a 

onetime fluorescent penetrant 

inspection (FPI) and eddy current 

inspection (ECI) of the propeller hub for 

cracks. That proposed AD resulted from 

reports of 3 hubs found cracked during 

propeller overhaul. This supplemental 

NPRM would require the same 

inspections. This supplemental NPRM 

results from reports of 7 additional hubs 

found cracked during propeller 

overhaul, totaling 10 cracked hubs. We 

are proposing this supplemental AD to 

prevent failure of the propeller hub, 

which could cause blade separation, 

damage to the airplane, and loss of 

control of the airplane. 

DATES: We must receive any comments 

on this proposed AD by June 14, 2010. 

ADDRESSES: Use one of the following 

addresses to comment on this proposed 

AD.

Discussion 

On September 24, 2007, we issued a 

proposal to amend part 39 of the Code 

of Federal Regulations (14 CFR part 39) 

to add an AD, for McCauley Propeller 

Systems model 4HFR34C653/L106FA 

propellers. The proposed AD published 

as an NPRM in the Federal Register on 

September 28, 2007 (72 FR 55120). That 

NPRM proposed to require a onetime 

FPI and ECI of the propeller hub for 

cracks. That NPRM resulted from 

reports of 3 hubs found cracked during 

propeller overhaul. 

Since we issued that NPRM, we 

received reports of 7 additional hubs 

found cracked during propeller 

overhaul. That brings the total of hubs 

that have had cracks located in the hub 

socket region, in the area of the outer 

bearing race press-fit surfaces, to 10. To 

date, the cause of these cracks appears 

to be fretting damage between the outer 

bearing race and the hub surface. This 

condition, if not corrected, could result 

in failure of the propeller hub, which 

could cause blade separation, damage to 

the airplane, and loss of control of the 

airplane. 

Also since we issued that NPRM, we 

eliminated the reporting requirement to 

McCauley Propeller Systems. 

Comments 

We provided the public the 

opportunity to participate in the 

development of that proposed AD. We 

have considered the comment received 

on the original NPRM. 

Proposed AD Should Also Set a Time 

Limit 

One commenter, a private citizen, 

recommends that the proposed AD also 

set a time limit on when inspections 

should take place. The commenter 

recommends an hour limit, and a yearold limit. We infer that the commenter 

is asking for a calendar time limit as 

well as the proposed operating hour 

time-since-new limit, to ensure the 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
Federal Register / Vol. 75, No. 70 / Tuesday, April 13, 2010 / Proposed Rules 18775 

inspection occurs in a more timely 

manner. 

We do not agree. The hub failure 

mechanism appears to be fretting 

damage which results in crack 

formation and subsequent growth. 

Propellers that are not operating do not 

accumulate fretting damage. Therefore, 

we cannot justify the use of calendar 

time. We did not change the proposed 

AD. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of McCauley 

Propeller Systems Alert Service Bulletin 

(ASB) No. ASB254, dated August 20, 

2007. That ASB describes procedures 

for a onetime FPI and ECI of propeller 

hubs for cracks. 

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 a onetime FPI and 

ECI of propeller hubs for cracks. The 

proposed AD would require you to use 

the service information described 

previously to perform these actions. 

Interim Action 

These actions are interim actions and 

we may take further rulemaking actions 

in the future. 

Costs of Compliance 

We estimate that this supplemental 

proposed AD would affect 128 

propellers installed on airplanes of U.S. 

registry. We also estimate that it would 

take about 41.5 work-hours per 

propeller to perform the proposed 

actions, and that the average labor rate 

is $85 per work-hour. Based on these 

figures, we estimate the total cost of the 

proposed AD to U.S. operators to be 

$451,520. 

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 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. 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 regulatory evaluation 

of the estimated costs to comply with 

this proposed AD. You may get a copy 

of this summary at the address listed 

under ADDRESSES.

procedures in paragraphs (h) through (k) of 

this AD within 100 operating hours time-inservice (TIS) after the effective date of this 

AD. 

(g) For propeller hubs with fewer than 

6,000 operating hours TSN on the effective

hours TSN. 

Onetime Propeller Hub Inspection 

(h) Remove and disassemble the propeller, 

and etch the propeller hub, using paragraphs 

1.A. through 2.D. of the Accomplishment 

Instructions of McCauley Propeller Systems

McCauley Propeller Systems Alert Service 

Bulletin No. ASB254, dated August 20, 2007. 

(k) Remove cracked hubs from service and 

any other propeller parts found cracked. 

Previous Credit

of the propeller hub using McCauley 

Propeller Systems Service Bulletin No. 

SB238A, or Alert Service Bulletin ASB254, 

both dated August 20, 2007, before the 

effective date of this AD, you have satisfied 

the inspection requirements of this AD. 

Interim Action 

(m) These actions are interim actions and 

we may take further rulemaking actions in 

the future. 

Alternative Methods of Compliance 

(n) The Manager, Wichita Aircraft 

Certification Office, has the authority to 

approve alternative methods of compliance 

for this AD if requested using the procedures

Regulated Navigation Area; Galveston 

Channel, TX 

AGENCY: Coast Guard, DHS. 

ACTION: Notice of proposed rulemaking. 

SUMMARY: The Coast Guard proposes to 

establish a regulated navigation area 

across the entire width of the Galveston 

Channel in the vicinity of Sector Field 

Office (SFO) Galveston. This regulated 

navigation area would require vessels to 

navigate at no wake speeds within this 

area. Vessel transits at greater than 

minimum safe speed and causing wake 

in this area would be prohibited unless 

specifically authorized by the Captain of 

the Port Houston-Galveston or a 

designated representative. This 

regulated navigation area is needed to 

protect the Coast Guard Sector Field 

Office (SFO) Galveston vessels, break 

wall, and piers from further damage 

associated with excessive wake and to 

protect ongoing base construction. 

DATES: Comments and related material 

must reach the Coast Guard on or before 

May 13, 2010. 

ADDRESSES: You may submit comments 

identified by Coast Guard docket 

number USCG–2009–0931 using any
