AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

During a normal walkaround check on a 

F28 Mark 0100 aeroplane, a large crack was 

discovered in the lower portion of the right 

(RH) MLG [main landing gear] piston. The 

affected MLG unit had accumulated 7909 

flight cycles (FC) at the time of detection. 

* * * 

This condition, if not detected and 

corrected, could lead to MLG failure, 

possibly resulting in loss of control of the 

aeroplane during the landing roll-out. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 6, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2009–0221, 

dated October 14, 2009 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

During a normal walkaround check on a 

F28 Mark 0100 aeroplane, a large crack was 

discovered in the lower portion of the right 

(RH) MLG [main landing gear] piston. The 

affected MLG unit had accumulated 7909 

flight cycles (FC) at the time of detection. The 

piston has been sent to Goodrich, the landing 

gear manufacturer, for detailed investigation. 

This condition, if not detected and 

corrected, could lead to MLG failure, 

possibly resulting in loss of control of the 

aeroplane during the landing roll-out. 

For the reasons described above, this AD 

requires a one-time detailed visual inspection 

of the MLG pistons, the replacement of any 

MLG pistons on which cracks are detected, 

and the reporting of all findings to the 

aeroplane TC [type certificate] holder. The 

inspection results, in combination with the 

findings of the crack/metallurgical 

investigation of the cracked piston by 

Goodrich, will be used to determine the 

necessity of additional and/or more detailed 

inspections, or any other corrective action. 

This AD is considered an interim measure, 

and further action is likely to follow. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Fokker Services B.V. has issued 

Service Bulletin SBF100–32–158, dated 

October 2, 2009. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 6 products of U.S. registry. 

We also estimate that it would take 

about 3 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$1,530, or $255 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 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); 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 proposed AD 

and placed it in the AD docket.

41060–6. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 


jdjones on DSK8KYBLC1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 203 / Thursday, October 21, 2010 / Proposed Rules 64965 

During a normal walkaround check on a 

F28 Mark 0100 aeroplane, a large crack was 

discovered in the lower portion of the right 

(RH) MLG piston. The affected MLG unit had 

accumulated 7909 flight cycles (FC) at the 

time of detection. The piston has been sent 

to Goodrich, the landing gear manufacturer, 

for detailed investigation. 

This condition, if not detected and 

corrected, could lead to MLG failure, 

possibly resulting in loss of control of the 

aeroplane during the landing roll-out. 

For the reasons described above, this AD 

requires a one-time detailed visual inspection 

of the MLG pistons, the replacement of any 

MLG pistons on which cracks are detected, 

and the reporting of all findings to the 

aeroplane TC [type certificate] holder. The 

inspection results, in combination with the 

findings of the crack/metallurgical 

investigation of the cracked piston by 

Goodrich, will be used to determine the 

necessity of additional and/or more detailed 

inspections, or any other corrective action. 

This AD is considered an interim measure, 

and further action is likely to follow. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Inspection 

(g) Within 30 days after the effective day 

of this AD, do a detailed visual inspection for 

cracks of the MLG pistons, in accordance 

with the Accomplishment Instructions of 

Fokker Service Bulletin SBF100–32–158, 

dated October 2, 2009. 

(h) If any cracked MLG piston is found 

during the inspection required by paragraph 

(g) of this AD, before further flight replace the 

affected piston with a serviceable part, in 

accordance with the Accomplishment 

Instructions of Fokker Service Bulletin 

SBF100–32–158, dated October 2, 2009. 

(i) At the applicable time specified in 

paragraph (i)(1) or (i)(2) of this AD, report the 

inspection results (including no findings) to 

Fokker Services B.V. by using the 

Questionnaire provided in Fokker Service 

Bulletin SBF100–32–158, dated October 2, 

2009. 

(1) If the inspection was done on or after 

the effective date of this AD: Submit the 

report within 30 days after the inspection. 

(2) If the inspection was done before the 

effective date of this AD: Submit the report 

within 30 days after the effective date of this 

AD. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: The 

applicability of the MCAI includes MLG part 

number (P/N) 41050–6, which is not an 

affected part. P/N 41060–6, however, is an 

affected part, and is included in the 

applicability of this AD. 

Other FAA AD Provisions 

(j) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

Send information to ATTN: Tom Rodriguez, 

Aerospace Engineer, International Branch, 

ANM–116, Transport Airplane Directorate, 

FAA, 1601 Lind Avenue, SW., Renton, 

Washington 98057–3356; telephone 425– 

227–1137; fax 425–227–1149. Before using 

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

principal maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

The AMOC approval letter must specifically 

reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control
