ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for MD 

Helicopters, Inc. (MDHI), Model MD900 

helicopters. This AD requires an eddy 

current inspection of the main rotor 

upper hub assembly (upper hub) for a 

crack and replacing the upper hub with 

an airworthy upper hub before further 

flight if there is a crack. This AD is 

prompted by a report of cracks on an 

upper hub at the blade attach holes. The 

actions specified by this AD are 

intended to detect a crack in the upper 

hub to prevent failure of the upper hub 

and subsequent loss of control of the 

helicopter. 

DATES: This AD becomes effective 

August 20, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD 

as of August 20, 2014.

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments prior to it becoming effective. 

However, we invite you to participate in 

this rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that resulted from 

adopting this AD. The most helpful 

comments reference a specific portion of 

the AD, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit them only one time. We will file 

in the docket all comments that we 

receive, as well as a report summarizing 

each substantive public contact with 

FAA personnel concerning this 

rulemaking during the comment period. 

We will consider all the comments we 

receive and may conduct additional 

rulemaking based on those comments. 

Discussion 

We are adopting a new AD for MDHI 

Model MD900 helicopters. This AD 

requires cleaning the upper hub and 

performing an eddy current inspection 

of the upper hub for a crack. If there is 

a crack, this AD requires replacing the 

upper hub with an airworthy upper hub 

before further flight. This AD is 

prompted by a report that four cracks 

were found at the blade attach holes on 

a high-time upper hub. This is the first 

time a crack has been reported in an 

upper hub at this location in the MD900 

fleet. We are issuing this AD to detect 

a crack on the upper hub, which if not 

corrected could result in failure of the 

upper hub and subsequent loss of 

control of the helicopter. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other helicopters of the same 

type design. 

Related Service Information 

MDHI has issued Service Bulletin 

SB900–122, dated April 8, 2014. The 

service bulletin specifies a one-time 

visual inspection of the upper hub for 

a crack and damage. If there is damage, 

the service bulletin specifies replacing 

the upper hub with an airworthy upper 

hub. If there are no visible cracks or 

damage, the service bulletin specifies 

performing a one-time eddy current 

inspection. If there is a crack, the 

service bulletin specifies removing the 

upper hub, tagging it as unairworthy 

and returning it to MDHI, and replacing 

it with an airworthy upper hub. 

AD Requirements 

This AD requires, within the next 25 

hours time-in-service (TIS) or at the next 

annual inspection, whichever occurs 

first, cleaning the upper hub inspection 

areas and eddy current inspecting the 

upper hub for a crack. The eddy current 

inspection must be done by a level II or 

higher technician with the National 

Aerospace Standard 410 or equivalent 

certification who has performed an eddy 

current inspection in the last 12 months. 

If there is a crack, before further flight, 

this AD requires replacing the upper 

hub with an airworthy upper hub. 

Differences Between This AD and the 

Service Information 

This AD does not require you to 

contact the manufacturer, return a 

cracked upper hub to the manufacturer, 

or do a visual inspection of the upper 

hub, as does the service information. 

Interim Action 

We consider this AD interim action. If 

final action is later identified, we might 

consider further rulemaking then. 

Costs of Compliance 

We estimate that this AD will affect 

23 helicopters of U.S. Registry. We 

estimate $85 for labor costs. We estimate 

1 work hour to do an eddy current 

inspection for a cost of $85 per 

helicopter and a total fleet cost of 

$1,955. We estimate 11 work hours to 

replace an upper hub with a required 

parts cost of $15,998 for a total cost of 

$16,933 per helicopter. 

FAA’s Justification and Determination 

of the Effective Date 

Providing an opportunity for public 

comments before adopting these AD 

requirements would delay 

implementing the safety actions needed 

to correct this known unsafe condition. 

Therefore, we find that the risk to the 

flying public justifies waiving notice 

and comment before adopting this rule 

because the required corrective actions 

must be done within 25 hours TIS, 

which will be accumulated in about one 

month based on the average flight-hour 

utilization rate of these helicopters that 

are mostly used for emergency medical 

service. 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we determined that notice an 

opportunity for public comment before 

issuing this AD are impracticable and 

contrary to the public interest and that 

good cause exists for making this 

amendment effective in less than 30 

days. 

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, 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 89–12–10, 

for certain The Boeing Company Model 

747 airplanes. AD 89–12–10 required 

replacement of certain underwing fuel 

tank access doors with stronger, fireresistant doors. This new AD requires 

inspecting certain fuel tank access doors 

for installation of impact-resistant 

doors, and stencils and index markers; 

corrective actions if necessary; revising 

the maintenance program to incorporate 

certain new airworthiness limitations; 

and adding airplanes to the 

applicability. This AD was prompted by 

a report of a standard access door 

installed instead of an impact-resistant 

access door and stencils missing from 

some impact-resistant access doors and 

adjacent wing skin. We are issuing this 

AD to prevent foreign object penetration 

of the fuel tank, which could cause a 

fuel leak near an ignition source (e.g., 

hot brakes or engine exhaust nozzle), 

consequently leading to a fuel-fed fire. 

DATES: This AD is effective September 9, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 9, 2014.
