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: 

An A300–600 operator reported two events 

of IPECO pilot seat moved in the aft position, 

one during take-off roll and one during climb 

out. The investigation of these events showed 

that a broken/missing spring contributed to 

the seat not being correctly locked. 

An unwanted movement of pilot or copilot seat in the aft direction is considered as 

potentially dangerous, especially during the 

take-off phase when the speed of the 

aeroplane is greater than 100 knots and until 

landing gear retraction. 

* * * * * 

The unsafe condition is potential loss of 

control of the airplane during take-off 

and landing. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

March 30, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 30, 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 July 16, 2009 (74 FR 34509). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

An A300–600 operator reported two events 

of IPECO pilot seat moved in the aft position, 

one during take-off roll and one during climb 

out. The investigation of these events showed 

that a broken/missing spring contributed to 

the seat not being correctly locked. 

An unwanted movement of pilot or copilot seat in the aft direction is considered as 

potentially dangerous, especially during the 

take-off phase when the speed of the 

aeroplane is greater than 100 knots and until 

landing gear retraction. 

To prevent further incidents of inadvertent 

flight crew seat aft movement, this AD 

requires repetitive inspections of the affected 

seat springs and replacement of missing or 

broken parts. In addition, this AD requires 

replacement of the affected seats with 

modified P/N 3A218–000X–01–2 seats. 

Installation of both pilot and co-pilot seats P/ 

N 3A218–000X–01–2 on an aeroplane 

constitutes terminating action for the 

repetitive inspection requirements of this AD 

for that aeroplane. 

The unsafe condition is potential loss of 

control of the airplane during take-off 

and landing. 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 

considered the comments received. 

Support for the AD 

The Air Line Pilots Association, 

International (ALPA), supports the 

NPRM. 

Request for Extension of Proposed 

Compliance Time for Modification 

FedEx and UPS request that we 

extend the compliance time for the 

modification specified in paragraph 

(f)(4) of the NPRM from 6 months to 30 

months. The commenters explain that 6 

months does not provide enough time 

for large operators with many aircraft to 

receive the parts kits. UPS explains 

further that their proposed compliance 

time will enable adequate industry 

support of the modification and at the 

same time enable operators to utilize 

regularly scheduled maintenance 

opportunities. 

We disagree with extending the 

proposed compliance time for the 

modification. While we recognize that 

mstockstill on DSKH9S0YB1PROD with RULES

Federal Register / Vol. 75, No. 35 / Tuesday, February 23, 2010 / Rules and Regulations 7943 

the initial lead time for parts kit 

delivery was excessive, IPECO now has 

a large stock of complete parts kits ready 

to be delivered. No further issue 

regarding availability of parts kits is 

foreseen. However, if parts kits 

availability becomes a problem in the 

future, under the provisions of 

paragraph (g)(1) of this AD, we will 

consider requests for approval of an 

extension of the compliance time if data 

are submitted to substantiate that the 

extension would provide an acceptable 

level of safety, provided that the 

operators are performing the repetitive 

inspections specified in paragraph (f) of 

this AD. We have made no change to the 

AD in this regard. 

Request for Permission To Replace Old 

Parts With New Parts 

FedEx requests that we revise the 

NPRM to allow for replacing the 

existing locking springs with new 

springs of the same design as an interim 

action to delay installation of the 

modification. FedEx explains that all of 

its broken locking springs were found 

on seats that had been in service at least 

4 years since there was a record of the 

springs being changed. FedEx states that 

the springs that were returned appeared 

to be corroded, which indicates that the 

failure of the springs was due to 

corrosion instead of fatigue. 

We do not agree with the request to 

revise this AD to allow for replacing the 

existing locking springs with new 

springs of the same design as an interim 

action to delay installation of the 

modification. While we recognize 

FedEx’s assertion that failure of the 

springs was due to corrosion instead of 

fatigue, Airbus did not identify which 

failure mode was actually involved, as 

fatigue cracks could induce spring 

protection alteration and then corrosion. 

Further, it is possible that corrosion 

could actually lead to the weakening of 

the spring, where the fatigue effort 

would deteriorate the spring. Regardless 

of the findings by FedEx, parts kits are 

now available for the replacement of the 

locking springs, so there is no need to 

delay installation of the modification. 

However, if operators experience a 

delay in receiving kits, they may request 

approval of an AMOC in accordance 

with the procedures in paragraph (g)(1) 

of this AD. We have made no change to 

the AD in this regard. 

Request To Use an Alternate Inspection 

Method 

FedEx requests that the NPRM be 

revised to allow operators to use other 

methods to perform the detailed 

inspection required in paragraph (f)(1) 

of this AD. FedEx explains that 

removing the seat bottom cushion and 

trying to view the springs through 

lightening holes in the seat bottom is 

difficult. FedEx explains further that 

maintenance personnel have used a 

mirror to perform the inspection or 

inspected the seat springs by looking up 

directly from underneath the seat. 

FedEx indicates that the springs are 

exposed on the bottom side of the seats 

and can be more easily viewed for 

defects by using this method. 

We agree that other methods of 

performing the detailed inspection 

required in paragraph (f)(1) of this AD 

might exist for the reasons stated in the 

previous paragraph. But, we do not 

agree to change this AD in this regard 

because insufficient data have been 

submitted to substantiate that the 

alternative inspection method would 

provide an acceptable level of safety. 

However, under the provisions of 

paragraph (g)(1) of this AD, we will 

consider requests for approval of an 

alternative inspection method if 

sufficient data are submitted to 

substantiate that the alternative 

inspection method would provide an 

acceptable level of safety. 

Request for Clarification 

UPS requests that we change the word 

‘‘modified’’ in paragraph (f)(3) of the 

NPRM to clarify that there is no 

modification required by that paragraph. 

UPS explains that the service 

information listed in paragraph (f)(3) of 

the NPRM requires inspection and 

replacement, but not modification. 

We agree to clarify paragraph (f)(3) of 

this final rule for the reason stated by 

UPS. We have changed ‘‘modified’’ to 

‘‘replaced’’ in paragraph (f)(3) of this AD. 

Explanation of Additional Change 

We have specified the issue numbers 

of each Airbus operations engineering 

bulletin throughout this final rule to 

adhere to requirements of the Office of 

the Federal Register’s (OFR), for 

material incorporated by reference 

(IBR). 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

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. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the NPRM, we have 

increased the labor rate used in the 

Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of 

Compliance information, below, reflects 

this increase in the specified hourly 

labor rate. 

Costs of Compliance 

We estimate that this AD will affect 

132 products of U.S. registry. We also 

estimate that it will take about 11 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 $1,214 

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 

$283,668, or $2,149 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: 

2010–04–13 Airbus: Amendment 39–16206. 

Docket No. FAA–2009–0615; Directorate 

Identifier 2009–NM–043–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 30, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to the airplanes 

identified in paragraphs (c)(1) and (c)(2) of 

the AD, certificated in any category, having 

IPECO part number (P/N) 3A218–000X–01–1 

pilot or co-pilot mechanical seats installed. 

(1) Airbus Model A310–203, A310–221, 

and A310–222 airplanes, all serial numbers. 

(2) Airbus Model A300 F4–605R and A300 

F4–622R airplanes, all serial numbers. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 25: Equipment/Furnishings. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

An A300–600 operator reported two events 

of IPECO pilot seat moved in the aft position, 

one during take-off roll and one during climb 

out. The investigation of these events showed 

that a broken/missing spring contributed to 

the seat not being correctly locked. 

An unwanted movement of pilot or copilot seat in the aft direction is considered as 

potentially dangerous, especially during the 

take-off phase when the speed of the 

aeroplane is greater than 100 knots and until 

landing gear retraction. 

To prevent further incidents of inadvertent 

flight crew seat aft movement, this AD 

requires repetitive inspections of the affected 

seat springs and replacement of missing or 

broken parts. In addition, this AD requires 

replacement of the affected seats with 

modified P/N 3A218–000X–01–2 seats. 

Installation of both pilot and co-pilot seats P/ 

N 3A218–000X–01–2 on an aeroplane 

constitutes terminating action for the 

repetitive inspection requirements of this AD 

for that aeroplane. 

The unsafe condition is potential loss of 

control of the airplane during take-off and 

landing. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 90 days after the effective date 

of this AD, and thereafter at intervals not to 

exceed 30 days, do a detailed visual 

inspection of the two springs of the pilot seat 

and co-pilot seat locking device, in 

accordance with Airbus Mandatory Service 

Bulletin A310–25A2199 or A300–25A6210, 

both dated July 9, 2008, as applicable. 

(i) If only one spring is missing or found 

damaged during any inspection required by 

paragraph (f)(1) of this AD, within 10 days 

after the inspection or before further flight, 

whichever occurs later, replace the spring 

with a serviceable part, in accordance with 

Airbus Mandatory Service Bulletin A310– 

25A2199 or A300–25A6210, both dated July 

9, 2008, as applicable. Before an airplane 

may be dispatched with one spring missing 

or damaged, the instructions contained in 

Airbus A310 Operations Engineering Bulletin 

160, Issue 2, dated October 2008; or Airbus 

A300–600 Operations Engineering Bulletin 

121, Issue 1, dated May 2008; as applicable; 

must be accomplished by the flightcrew. 

(ii) If two springs are missing or found 

damaged during any inspection required by 

paragraph (f)(1) of this AD, before further 

flight, replace the springs in accordance with 

Airbus Mandatory Service Bulletin A310– 

25A2199 or A300–25A6210, both dated July 

9, 2008, as applicable. 

(2) Replacing parts in accordance with 

Airbus Mandatory Service Bulletin A310– 

25A2199 or A300–25A6210, both dated July 

9, 2008, as applicable, is not a terminating 

action for the repetitive inspections required 

in paragraph (f)(1) of this AD. 

(3) As of the effective date of this AD, do 

not install an IPECO pilot or co-pilot 

mechanical seat P/N 3A218–000X–01–1 on 

any airplane, unless the seat has been 

inspected and replaced as applicable, in 

accordance with Airbus Mandatory Service 

Bulletin A310–25A2199 or A300–25A6210, 

both dated July 9, 2008, as applicable. 

(4) Within 6 months after the effective date 

of this AD, modify the airplane by replacing 

the pilot and co-pilot mechanical seats P/N 

3A218–000X–01–1 with P/N 3A218–000X– 

01–2 seats, in accordance with Airbus 

Mandatory Service Bulletin A310–25–2202 

or A300–25–6214, both dated February 3, 

2009, as applicable. 

(5) Installing both pilot and co-pilot seats 

P/N 3A218–000X–01–2 in accordance with 

Airbus Mandatory Service Bulletin A310–25– 

2202 or A300–25–6214, both dated February 

3, 2009, as applicable, on any airplane is a 

terminating action for the repetitive 

inspections required by paragraph (f)(1) of 

this AD for that airplane. 

(6) As of 6 months after the effective date 

of this AD, do not install an IPECO pilot or 

co-pilot mechanical seat P/N 3A218–000X– 

01–1 on any airplane. 

(7) Although Airbus Mandatory Service 

Bulletins A310–25A2199 and A300– 

25A6210, both dated July 9, 2008, specify to 

submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

Although the MCAI or service information 

tells you to submit information to Airbus, 

paragraph (f)(7) of this AD specifies that such 

submittal is not required. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to

Airworthiness Directives; Augustair,

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Augustair, Inc. Models 2150, 2150A, 

and 2180 airplanes. This AD requires 

you to inspect the vertical stabilizer 

front spar for cracks and loose fasteners, 

repair any cracks and loose fasteners 

found, and reinforce the vertical 

stabilizer spar regardless if cracks are 

found. This AD results from six reports 

of airplanes with a cracked vertical 

stabilizer front spar. We are issuing this 

AD to detect and correct cracks in the 

vertical stabilizer front spar, which 

could result in separation of the vertical 

stabilizer from the airplane. This failure 

could lead to loss of control. 

DATES: This AD becomes effective on 

March 24, 2010. 

On March 24, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD. 

We must receive any comments on 

this AD by April 9, 2010.
