have met the requirements of this AD when 

you modify your continuous airworthiness 

maintenance plan to reflect those changes. 

You do not need to record each piece-part 

inspection as compliance to this AD, but you 

must maintain records of those inspections 

according to the regulations governing your 

operation. For air carriers operating under 

part 121, you may use either the system 

established to comply with section 121.369 

or an alternative accepted by your principal 

maintenance inspector if that alternative: 

(1) Includes a method for preserving and 

retrieving the records of the inspections 

resulting from this AD; and 

(2) Meets the requirements of section 

121.369(c); and 

(3) Maintains the records either 

indefinitely or until the work is repeated. 

(l) These record keeping requirements 

apply only to the records used to document 

the mandatory inspections required as a 

result of revising the TLS of the 

manufacturer’s engine manual as specified in 

paragraph (f) of this AD. These record 

keeping requirements do not alter or amend 

the record keeping requirements for any 

other AD or regulatory requirement.

and 0100 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (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) 

originated 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: 

The flight crew of a F28 Mark 0070 (Fokker 

70) aeroplane received a MLG [main landing 

gear] unsafe message after landing gear down 

selection during approach. * * * 

Inspection just after landing revealed a lot 

of ice near the LH [left-hand] MLG downlock 

actuator. * * * 

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

March 22, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 22, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (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 November 15, 2010 (75 FR 

69606). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

The flight crew of a F28 Mark 0070 (Fokker 

70) aeroplane received a MLG [main landing 

gear] unsafe message after landing gear down 

selection during approach. After cycling the 

landing gear, only a LH [left-hand] MLG 

unsafe indication remained. A go-around was 

initiated and alternate landing gear down 

selection was performed twice, but the LH 

MLG did not lock down. During final 

approach, without further flight crew action, 

all 3 green lights illuminated and an 

uneventful landing was made. 

Inspection just after landing revealed a lot 

of ice near the LH MLG downlock actuator. 

Further investigation revealed that the piston 

rod of the downlock actuator had failed at the 

threaded end close to the eye end, which is 

attached to the lower lock link, and that the 

piston rod was broken in an overload by 


jdjones on DSK8KYBLC1PROD with RULES
Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Rules and Regulations 8623 

bending in the neck close to the threaded 

end. 

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out. 

To address this unsafe condition and 

prevent the accumulation of water, slush 

and/or snow, Goodrich, the MLG 

manufacturer, has introduced a new upper 

side brace, Part Number (P/N) 41350–3, 

which has two additional drain holes. 

Goodrich Service Bulletin (SB) 41350–32–25 

describes the modification of the P/N 41350– 

1 MLG upper side brace, introducing the two 

additional drain holes and consequent reidentification of the part to P/N 41350–3. 

For the reasons described above, this AD 

requires modification of both (LH and RH 

[right-hand]) P/N 41350–1 MLG upper side 

braces, or replacement of the P/N 41350–1 

upper side braces with modified P/N 41350– 

3 upper side braces. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 6 

products of U.S. registry. We also 

estimate that it will take about 16 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $8,160, or 

$1,360 per product. 

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 the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

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: 

2011–04–07 Fokker Services B.V.: 

Amendment 39–16607. Docket No. 

FAA–2010–1112; Directorate Identifier 

2010–NM–051–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Fokker Services B.V. 

Model F.28 Mark 0070 and 0100 airplanes, 

certificated in any category; all serial 

numbers, if equipped with Goodrich 

(formerly Menasco, Colt Industries) main 

landing gears (MLGs) fitted with MLG upper 

side braces having part number (P/N) 41350– 

1. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing Gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

The flight crew of a F28 Mark 0070 (Fokker 

70) aeroplane received a MLG [main landing 

gear] unsafe message after landing gear down 

selection during approach. * * * 

Inspection just after landing revealed a lot 

of ice near the LH [left-hand] MLG downlock 

actuator. * * * 


jdjones on DSK8KYBLC1PROD with RULES
8624 Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Rules and Regulations 

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out. 

* * * * *
