airplanes. 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 need 

to incorporate new revisions into the 

aircraft maintenance manual or in the 

limitations document of the FAAapproved maintenance program. We are 

issuing this AD to require actions to 

address the unsafe condition on these 

products. 

DATES: This AD is effective January 16, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of January 16, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to add an AD that would apply 

to Pilatus Aircraft Limited Models PC– 

6, PC–6–H1, PC–6–H2, PC–6/350, PC–6/ 

350–H1, PC–6/350–H2, PC–6/A, PC–6/

A–H1, PC–6/A–H2, PC–6/B–H2, PC–6/

B1–H2, PC- 6/B2–H2, PC–6/B2–H4, PC– 

6/C–H2, and PC–6/C1–H2 airplanes. 

That NPRM was published in the 

Federal Register on September 18, 2014 

(79 FR 56023), and proposed to 

supersede AD 2013–11–08, Amendment 

39–17468 (78 FR 37701; June 24, 2013). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products and was based on mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country. The MCAI 

states that: 

The maintenance instructions and 

airworthiness limitations applicable to the 

Structure and Components of PC–6 

aeroplanes are specified in the Aircraft 

Maintenance Manual (AMM) under Chapter 

4 or in the Airworthiness Limitations 

Document (ALS), depending on aeroplane 

model. 

The instructions contained in the ALS 

document have been identified as mandatory 

actions for continued airworthiness and 

failure to comply with these instructions and 

limitations could potentially lead to an 

unsafe condition. 

Pilatus Aircraft Ltd. (Pilatus) recently 

issued PC–6 AMM, Chapter 04–00–00, 

Document Number 01975 issue 19 for PC–6 

B2–H2 and PC–6 B2–H4 aeroplanes and PC– 

6 ALS, Document Number 02334 issue 4 for 

all other PC–6 aeroplane models to 

incorporate new life limits for the Fire 

Extinguisher. 

For the reason described above, this AD 

retains the requirements of EASA AD 2012– 

0268, which is superseded, and requires 


rljohnson on DSK3VPTVN1PROD with RULES
73804 Federal Register / Vol. 79, No. 239 / Friday, December 12, 2014 / Rules and Regulations 

implementation of the new maintenance 

requirements and/or airworthiness 

limitations. 

The MCAI can be found in the AD 

docket on the Internet at: http://

www.regulations.gov/

#!docketDetail;D=FAA-2014-0717. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comment 

received on the proposal and the FAA’s 

response to the comment. 

Request 

John Kruger of Pilatus Aircraft 

Limited commented that paragraph 

(f)(4)(ii) of this AD provides a 

compliance time of 30 days after 

effective date of the AD or within 10 

hours time-in-service, but that Pilatus 

had recommended in the MCAI to allow 

a grace period of 6 months, as was done 

in the case of the PC–12 when the fire 

extinguisher life was changed, and that 

the compliance time should be changed 

for this AD per the recommendation. 

We agree because the compliance 

time of 6 months allows for an 

acceptable level of safety. We revised 

the AD so that the compliance time in 

paragraph (f)(4)(ii) of this AD reads 

‘‘. . . within 6 months after . . .’’ 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

56023, September 18, 2014) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 56023, 

September 18, 2014). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

50 products of U.S. registry. We also 

estimate that it would take about 8 

work-hours per product to comply with 

the basic requirements of this AD. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $34,000, or $680 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $1,000, for a cost of $1,085 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

The only costs that would be imposed 

by this AD over that already required by 

AD 2013–11–08 is 1 work-hour to 

incorporate the new airworthiness 

limitations section sections into the 

maintenance program, $1,085 for 

replacement of the fire extinguisher if 

needed, and the addition of 35 airplanes 

from 15 airplanes to 50 airplanes. 

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), 

(3) Will not affect intrastate aviation 

in Alaska, 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.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777 

airplanes. This AD was prompted by 

reports of corroded, migrated, or broken 

spring pins of the girt bar floor fitting; 

in one case the broken pins prevented 

a door escape slide from deploying 

during a maintenance test. This AD 

requires replacing the existing spring 

pins at each passenger entry door at 

both girt bar floor fittings with new 

spring pins. We are issuing this AD to 

prevent broken or migrated spring pins 

of the girt bar floor fittings, which could 

result in improper deployment of the 

escape slide/raft and consequent delay 

and injury during evacuation of 

passengers and crew from the cabin in 

the event of an emergency. 

DATES: This AD is effective January 16, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 16, 2015.
