Airworthiness Directives; SOCATA 

Model TBM 700 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above that would 

supersede an existing AD. 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 SOCATA flight test, it was noted 

some difficulties for the pilot to release 

oxygen. After investigation it was found that, 

due to the design of the oxygen generator 

release pin, one of the mask’s lanyard linked 

to the pin could be jammed when it is pulled 

by a pilot or a passenger. 

This condition, if not corrected, would 

lead, in case of an emergency procedure due 

to decompression, to a risk of generator fault 

with subsequent lack of oxygen on crew and/ 

or passenger. 

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 October 12, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

On November 6, 2009, we issued AD 

2009–23–12, Amendment 39–16086 

(74 FR 58539; November 13, 2009). That 

AD required actions intended to address 

an unsafe condition on the products 

listed above. AD 2009–23–12 revised 

AD 2009–13–05 (74 FR 29126, June 19, 

2009), which was intended to address 

an unsafe condition on the products 

listed above. 

Since we issued AD 2009–23–12, 

SOCATA has developed a modification 

that is a terminating action to address 

the unsafe condition. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2010– 

0090, dated May 18, 2010 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

During a SOCATA flight test, it was noted 

some difficulties for the pilot to release 

oxygen. After investigation it was found that, 

due to the design of the oxygen generator 

release pin, one of the mask’s lanyard linked 

to the pin could be jammed when it is pulled 

by a pilot or a passenger. 

This condition, if not corrected, would 

lead, in case of an emergency procedure due 

to decompression, to a risk of generator fault 

with subsequent lack of oxygen on crew and/ 

or passenger. 

For the reason described above, SOCATA 

released Pilot Operating Handbook (POH) 

Temporary Revision (TR) 03 which asks, in 

case of failure to release oxygen, to pull on 

the other mask lanyard in order to activate 

the oxygen generator. The Emergency AD 

2009–0096–E was issued to mandate the 

follow-up of these actions by the operators in 

case of failure. This EAD was subsequently 

revised into AD 2009–0096R1 in order to 

clarify the applicability. 

A SOCATA modification enabling to solve 

this issue has been developed. Consequently, 

this new AD, superseding EASA AD 2009– 

0096R1 retaining its requirements, requires 

implementing the modification which is a 

terminating action. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

SOCATA has issued SOCATA TBM 

700 A & B Pilot’s Operating Handbook 

(POH), Temporary Revision No. 3, dated 

March 2009; and DAHER–SOCATA 

TBM Aircraft Mandatory Service 

Bulletin SB 70–168, dated December 

2009. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI.

Federal Register / Vol. 75, No. 165 / Thursday, August 26, 2010 / Proposed Rules 52481 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed 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 

We estimate that this proposed AD 

will affect 126 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $66 per product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $19,026, or $151 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 

removing Amendment 39–16086 

(74 FR 58539; November 13, 2009), and 

adding the following new AD: 

SOCATA: Docket No. FAA–2010–0862; 

Directorate Identifier 2010–CE–040–AD. 

Comments Due Date 

(a) We must receive comments by October 

12, 2010. 

Affected ADs 

(b) This AD supersedes AD 2009–23–12, 

Amendment 39–16086. 

Applicability 

(c) This AD applies to Model TBM 700 

airplanes, serial numbers 1 through 204, 206 

through 239, and 241 through 243, that are: 

(i) Certificated in any category; and 

(ii) equipped with a chemical oxygen 

generation system. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 35: Oxygen. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During a SOCATA flight test, it was noted 

some difficulties for the pilot to release 

oxygen. After investigation it was found that, 

due to the design of the oxygen generator 

release pin, one of the mask’s lanyard linked 

to the pin could be jammed when it is pulled 

by a pilot or a passenger. 

This condition, if not corrected, would 

lead, in case of an emergency procedure due 

to decompression, to a risk of generator fault 

with subsequent lack of oxygen on crew and/ 

or passenger. 

For the reason described above, SOCATA 

released Pilot Operating Handbook (POH) 

Temporary Revision (TR) 03 which asks, in 

case of failure to release oxygen, to pull on 

the other mask lanyard in order to activate 

the oxygen generator. The Emergency AD 

2009–0096–E was issued to mandate the 

follow-up of these actions by the operators in 

case of failure. This EAD was subsequently 

revised into AD 2009–0096R1 in order to 

clarify the applicability. 

A SOCATA modification enabling to solve 

this issue has been developed. Consequently, 

this new AD, superseding EASA AD 2009– 

0096R1 retaining its requirements, requires 

implementing the modification which is a 

terminating action. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Before further flight after the effective 

date of this AD, insert Page 3.13.5 of 

Temporary Revision No. 3, dated March 

2009, into the Emergency Procedures section 

and the Limitations section of SOCATA TBM 

700 A & B Pilot’s Operating Handbook (POH). 

(2) Within 7 months after the effective date 

of this AD or 100 hours time-in-service (TIS) 

after the effective date of this AD, whichever 

occurs first, replace the existing oxygen 

generator release pin, part number (P/N) 

T700A3510038100, with an open pin, P/N 

T700A351004410000, using the 

accomplishment instructions of DAHER– 

SOCATA TBM Aircraft Mandatory Service 

Bulletin SB 70–168, dated December 2009. 

(3) Upon replacement of the existing 

oxygen generator release pin with an open 

pin, P/N T700A351004410000, using the 

accomplishment instructions of SB No. 70– 

168, remove Page 3.13.5 of Temporary 

Revision No. 3, dated March 2009, as 

inserted by paragraph (f)(1) of this AD from 

the POH. 

(4) After the effective date of this AD, do 

not install in any affected airplane an oxygen 

generator release pin, P/N 

T700A3510038100.

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: This Airworthiness 

Directive (AD) is prompted due to an 

occurrence when an aircraft had a 

partial in-flight separation of the aileron 

outboard bearing support. The aileron 

outboard bearing supports are attached 

with two forward attachment bolts and 

two aft attachment bolts. The forward 

attachment bolts are approximately 3.2 

mm (0.125 inch) longer than the aft 

attachment bolts. If the aileron outboard 

bearing supports have been removed, it 

is possible that during the reinstallation 

of the aileron outboard bearing 

supports, the attachment bolts can be 

installed in wrong positions. Bolts that 

are installed in wrong positions can 

damage the threads in the rear 

attachment anchor nuts. Such a 

condition, if left uncorrected, could lead 

to in-flight separation of the aileron 

outboard bearing support, and as a 

consequence, the loss or limited 

controllability of the aircraft. 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 October 12, 2010.
