Airworthiness Directives; Fokker 

Services B.V. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

2–Fokker Services B.V.2–Model F.28 

Mark 0100 airplanes. This AD was 

prompted by reports of failure of the 

main fitting on Messier-Dowty main 

landing gear (MLG) units due to fatigue 

cracking in the area of the filler and 

bleeder holes, and failure of the sliding 

member due to fatigue cracking at the 

area of the chrome run-out/lower radius 

of the sliding tube portion of the sliding 

member. This AD requires modification 

and re-identification of the MLG units, 

or replacement of the MLG unit with a 

modified one. We are issuing this AD to 

detect and correct fatigue cracking of the 

main fitting or sliding member on the 

MLG, which could lead to failure of the 

MLG and possibly loss of control of the 

airplane during landing rollout. 

DATES: This AD becomes effective June 

12, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 12, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of November 18, 2010 (75 FR 

63042, October 14, 2010).

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 7, 2011 (76 FR 

68668). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Since introduction of the F28 Mark 0100 

aeroplane into airline service, there have 

been a number of occurrences with MessierDowty MLG [main landing gear] units where 

the main fitting failed, due to fatigue cracking 

in the area of the filler and bleeder holes, and 

occurrences where the sliding member failed, 

due to fatigue cracking at the area of chrome 

run-out/lower radius of the sliding tube 

portion of the sliding member. 

Investigation has revealed that the most 

probable cause of both the main fitting and 

sliding member cracks is high compressive 

stress during braking at higher deceleration 

levels outside the regular fatigue load 

spectrum. Starting at deceleration stress 

levels somewhat below limit load, the high 

compressive stress locally exceeds the 

elasticity limit of the material, leaving a 

residual tensile stress at release of the heavy 

braking load. Subsequently, this local 

residual tensile stress results in a negative 

effect on the fatigue life of the component. 

This condition, if not detected and 

corrected, could lead to failure of the MLG, 

possibly resulting in loss of control of the 

aeroplane during the landing rollout. To 

address this unsafe condition, the Civil 

Aviation Authority of the Netherlands (CAA– 

NL) issued AD NL–2005–012 (EASA 

approval 2005–6363) [which corresponds to 

FAA 2007–04–23, Amendment 39–14956 (72 

FR 8615, February 27, 2007)] to require 

repetitive inspections of the sliding member 

(Fokker Services SBF100–32–144) and AD 

NL–2006–003 (EASA approval 2006–0041) to 

require repetitive inspections of the main 

fitting (Fokker Services SBF100–32–146). 

Messier-Dowty has now developed a 

modification, resulting in a strengthened 

sliding member and a strengthened main 

fitting, which is the terminating action for 

these repetitive inspections. 

For the reasons described above, this 

[EASA] AD requires the modification and 

reidentification of the affected MLG units, or 

replacement of the affected MLG units with 

modified units. 

This [EASA] AD has been revised to * * * 

state that modification of an aeroplane * * * 

also constitutes terminating action for the 

actions required by CAA–NL AD (BLA) 

2002–115/2 dated October 8, 2004 [which 

partially corresponds to FAA AD 2008–20– 

03, Amendment 39–15682 (73 FR 56452, 

September 29, 2008)]. 

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 (76 

FR 68668, November 7, 2011) or on the 

determination of the cost to the public. 

Explanation of Change Made to This 

AD 

We have revised paragraph (h)(2) of 

this AD to correct a typographical error. 

This error resulted in a reference to 

paragraph (c) of this AD instead of 

paragraph (g) of this AD. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes and/or format changes. We 

have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

68668, November 7, 2011) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 68668, 

November 7, 2011). 

Costs of Compliance 

We estimate that this AD will affect 4 

products of U.S. registry. We also 

estimate that it will take about 30 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 $520,000 

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 

$2,090,200, or $522,550 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 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 77, No. 89 / Tuesday, May 8, 2012 / Rules and Regulations 26949 

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 that 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. 

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,
