Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all The 

Boeing Company Model 777 airplanes. 

This proposed AD was prompted by a 

report of an incident involving a landing 

in which the pilots needed to input 

corrections due to airplane yaw and roll 

to the right; the main landing gear 

(MLG) aft trunnion pin was later found 

to be fractured. This proposed AD 

would require identification and 

replacement of certain MLG aft trunnion 

pins. We are proposing this AD to 

prevent a fractured MLG aft trunnion 

pin, which could result in collapse of 

the MLG and consequent loss of control 

of the airplane during landing. 

DATES: We must receive comments on 

this proposed AD by April 4, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2016–0463; Directorate Identifier 2015– 

NM–155–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received a report of an 

incident involving a landing in which 

the pilots needed to input corrections 

due to airplane yaw and roll to the right; 

the MLG aft trunnion pin was later 

found to be fractured. Other damage 

included minor damage to the gear 

beam and trunnion door panel and a 

broken tie rod. Analysis of the fractured 

pin showed that the crack started from 

an area of heat damage introduced 

during manufacturing. A review of gear 

overhaul records indicated that other 

pins manufactured by the same supplier 

had similar signs of heat damage, 

suspected to have been caused by 

abusive chrome grinding. This evidence 

suggests that the heat damage occurred 

during manufacturing, so it is possible 

that other airplanes have aft trunnion 

pins with similar heat damage. This 

condition, if not corrected, could result 

in collapse of the MLG and consequent 

loss of control of the airplane during 

landing. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin 777–32A0103, Revision 1, 

dated December 10, 2015. The service 

information describes procedures for 

identifying and replacing certain MLG 

aft trunnion pins. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously.

Federal Register / Vol. 81, No. 32 / Thursday, February 18, 2016 / Proposed Rules 8165 

Differences Between This Proposed AD 

and the Service Information 

Boeing Alert Service Bulletin 777– 

32A0103, Revision 1, dated December 

10, 2015, limits the effectivity to Model 

777 airplanes, line numbers 1 through 

1330 inclusive. However, this proposed 

AD does not propose to limit the 

applicability to those line numbers. The 

applicability of this proposed AD 

includes all The Boeing Company 

Model 777–200, 777–200LR, 777–300, 

777–300ER, and 777F series airplanes. 

Because the affected trunnion pins are 

rotable parts, we have determined that 

these parts could later be installed on 

airplanes that were initially delivered 

with acceptable pins, thereby subjecting 

those airplanes to the unsafe condition. 

This difference has been coordinated 

with Boeing. 

Explanation of ‘‘RC’’ Steps in Service 

Information 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee (ARC), to 

enhance the AD system. One 

enhancement was a new process for 

annotating which steps in the service 

information are required for compliance 

with an AD. Differentiating these steps 

from other tasks in the service 

information is expected to improve an 

owner’s/operator’s understanding of 

crucial AD requirements and help 

provide consistent judgment in AD 

compliance. The steps identified as 

Required for Compliance (RC) in any 

service information identified 

previously have a direct effect on 

detecting, preventing, resolving, or 

eliminating an identified unsafe 

condition. 

For service information that contains 

steps that are labeled as RC, the 

following provisions apply: (1) The 

steps labeled as RC, including substeps 

under an RC step and any figures 

identified in an RC step, must be done 

to comply with the AD, and an AMOC 

is required for any deviations to RC 

steps, including substeps and identified 

figures; and (2) steps not labeled as RC 

may be deviated from using accepted 

methods in accordance with the 

operator’s maintenance or inspection 

program without obtaining approval of 

an AMOC, provided the RC steps, 

including substeps and identified 

figures, can still be done as specified, 

and the airplane can be put back in an 

airworthy condition. 

Costs of Compliance 

We estimate that this proposed AD 

affects 123 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection ........................................................ 2 work-hours × $85 per hour = $170 ............. $0 $170 $20,910 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of aircraft that 

might need this repair: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement of aft trunnion pin ................................... 34 work-hours × $85 per hour = $2,890 ...................... $5,291 $8,181 

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 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 this proposed regulation: 

(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; Fokker 

Services B.V. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Fokker Services B.V. Model F.28 Mark 

0070 and 0100 airplanes. This proposed 

AD was prompted by the need for more 

restrictive airworthiness limitations. 

This proposed AD would require 

revising the maintenance program or 

inspection program, as applicable, to 

incorporate certain maintenance 

requirement tasks, thresholds, and 

intervals. We are proposing this AD to 

reduce the potential for significant 

failure conditions and consequent loss 

of controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by April 4, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
