Airworthiness Directives; Cessna 

Aircraft Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Cessna Aircraft Company Model 680 

airplanes. This AD was prompted by a 

false cross-feed command to the righthand fuel control card, due to the crossfeed inputs on the left- and right-hand 

fuel control cards being connected 

together and causing an imbalance of 

fuel between the left and right wing 

tanks. This AD requires adding diodes 

to the fuel cross-feed wiring, and 

revising the airplane flight manual to 

include procedures to use when the left 

or right generator is selected OFF. We 

are issuing this AD to prevent lateral 

imbalance of the airplane, resulting 

from uncontrolled fuel cross-feed, 

which can be corrected by deflecting the 

aileron trim; deflecting the aileron trim 

increases the pilot’s workload and could 

exceed the airplane’s limitation in a 

short period of time, resulting in 

reduced controllability of the airplane. 

DATES: This AD is effective May 15, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of May 15, 2012.

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 August 31, 2011 (76 FR 

54141), and proposed to require adding 

diodes to the fuel cross-feed wiring, and 

revising the airplane flight manual to 

include procedures to use when the left 

or right generator is selected OFF. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received from Cessna Aircraft Company 

(Cessna), the manufacturer, on the 

NPRM (76 FR 54141, August 31, 2011), 

and the FAA’s response to each 

comment. 

Requests To Correct References to 

Airplane Flight Manual (AFM) 

Revisions and Temporary Changes 

(TCs) in Paragraph (h) of This AD 

Cessna commented that the NPRM (76 

FR 54141, August 31, 2011) has 

incorrect references to certain AFM TCs, 

does not refer to certain applicable AFM 

TCs, and incorrectly addresses the 

procedure change in the recently FAAapproved Revision 10, dated June 30, 

2011, of the Cessna 680 Citation 

Sovereign AFM. We infer that Cessna 

requested that we correct references to 

the AFM revisions and TCs in paragraph 

(h) of the NPRM. 

Cessna also commented that the text 

for AFM revision 68FM–10, dated June 

30, 2011, of the Cessna 680 Citation 

Sovereign AFM, does not include the 

instruction to pull the fuel pump circuit 

breakers, which was part of the TC, and 

is not necessary once the modification 

specified in Cessna Service Bulletin 

680–24–11, dated December 16, 2010, is 

done. 

Cessna further commented that the 

wording of the NPRM (76 FR 54141, 

August 31, 2011) is incorrect in its 

reference to Cessna TC TC–R09–13, 

dated October 15, 2010, to the Cessna 

680 Citation Sovereign AFM, Revision 

9, dated May 24, 2010, and that the TC 

is applicable until Revision 10, dated 

June 30, 2011, of the Cessna 680 

Citation Sovereign AFM, is incorporated 

into the AFM. Further, the commenter 

stated that the remaining TCs for 

Revision 9, dated May 24, 2010, of the 

Cessna 680 Citation Sovereign AFM are 

to be removed when Revision 10 is 

incorporated, and there are 3 new TCs 

for Cessna 680 Citation Sovereign AFM, 

Revision 10, dated June 30, 2011, that 

are the same as the previous TCs for 

Cessna 680 Citation Sovereign AFM, 

Revision 9, dated May 24, 2010. 

We agree with Cessna’s requests for 

the reasons given. We have changed 

paragraph (h) of this AD to include the 

updated AFM revisions and current 

TCs. However, some operators still use 

Cessna 680 Citation Sovereign AFM, 

Revision 9, dated May 24, 2010, and 

therefore the TCs referenced in Cessna 

680 Citation Sovereign AFM, Revision 

9, dated May 24, 2010, still apply for 

some affected airplanes. Therefore, 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 69 / Tuesday, April 10, 2012 / Rules and Regulations 21421 

paragraph (h) of this AD clarifies the 

changes to the AFM as they apply to 

airplanes using Cessna 680 Citation 

Sovereign AFM, Revision 9, dated May 

24, 2010, and to airplanes using Cessna 

680 Citation Sovereign AFM, Revision 

10, dated June 30, 2011. These changes 

will not result in an additional burden 

to the operator. 

We have also reviewed Cessna Service 

Bulletin SB680–24–11, Revision 1, 

dated November 15, 2011. This service 

bulletin includes procedures to address 

both Cessna 680 Citation Sovereign 

AFM, Revision 9, dated May 24, 2010; 

and Cessna 680 Citation Sovereign 

AFM, Revision 10, dated June 30, 2011; 

and their corresponding AFM actions. 

We have also changed paragraph (g) of 

this AD to reference Cessna Service 

Bulletin SB680–24–11, Revision 1, 

dated November 15, 2011. We also 

added paragraph (i) to the AD to give 

credit for actions accomplished before 

the effective date of the AD using 

Cessna Service Bulletin SB680–24–11, 

dated December 16, 2010, and reidentified subsequent paragraphs 

accordingly. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously, 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

54141, August 31, 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 54141, 

August 31, 2011). 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

the AD. 

Costs of Compliance 

We estimate that this AD affects 198 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost 

on U.S. 

operators 

Installation ................................... 4 work-hours × $85 per hour = $340 ............................................. $40 $380 $75,240 

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 

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 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

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 airworthiness 

directive (AD): 

2012–07–04 Cessna Aircraft Company: 

Amendment 39–17010; Docket No. 

FAA–2011–0913; Directorate Identifier 

2011–NM–031–AD. 

(a) Effective Date 

This AD is effective May 15, 2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Cessna Aircraft 

Company Model 680 airplanes; certificated in 

any category; serial numbers –0001 through 

–0289 inclusive, and –0291 through –0296 

inclusive. 

(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 24: Electrical power. 

(e) Unsafe Condition 

This AD was prompted by a false crossfeed command to the right-hand fuel control 

card, due to the cross-feed inputs on the leftand right-hand fuel control cards being 

connected together and causing an imbalance 

of fuel between the left and right wing tanks. 

We are issuing this AD to prevent lateral 

imbalance of the airplane, resulting from 

uncontrolled fuel cross-feed, which can be 

corrected by deflecting the aileron trim; 

deflecting the aileron trim increases the 

pilot’s workload and could exceed the 

airplane’s limitation in a short period of time, 

resulting in reduced controllability of the 

airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Installation 

Within 400 flight hours or 12 months after 

the effective date of this AD, whichever 

occurs first: Install a kit, part number (P/N) 

SB680–24–11, to the left and right motive 

flow relays, in accordance with the 

Accomplishment Instructions of Cessna

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

all The Boeing Company Model 747– 

100, 747–100B, 747–100B SUD, 747– 

200B, 747–200C, 747–200F, 747–300, 

747–400, 747–400D, 747–400F, 747SR, 

and 747SP series airplanes. That AD 

currently requires an inspection of the 

No. 2 and No. 3 windows on the left and 

right sides of the airplane to determine 

their part numbers, related investigative 

and corrective actions if necessary, and 

repetitive inspections of single pane 

windows. This new AD requires 

installing dual pane No. 2 and No. 3 

windows. This new AD also removes 

certain airplanes from the applicability. 

This AD was prompted by loss of a No. 

3 window in flight, which could result 

in consequent rapid loss of cabin 

pressure. Loss of the window could also 

result in crew communication 

difficulties or incapacitation of the 

crew. We are issuing this AD to correct 

the unsafe condition on these products. 

DATES: This AD is effective May 15, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD
