AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

inspecting the wings for internal and 

external damage, repairing any damage, 

reinforcing the wings, installing 

operational limitation placards in the 

cockpit, and adding limitations to the 

airplane flight manual supplement. This 

AD was prompted by a review of 

installed Flint Aero, Inc. wing tip 

auxiliary fuel tanks, Supplemental Type 

Certificate (STC) SA5090NM. We are 

issuing this AD to detect and correct 

damage in the wings and to prevent 

overload failure of the wing due to the 

installation of the STC. Damage in the 

wing or overload failure of the wing 

could result in structural failure of the 

wing, which could result in loss of 

control. 

DATES: This AD is effective September 6, 

2011.

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 published in the Federal 

Register on May 4, 2011 (76 FR 25264). 

That NPRM proposed to require 

inspecting the wings for internal and 

external damage, repairing any damage, 

reinforcing the wings, installing 

operational limitation placards in the 

cockpit, and adding limitations to the 

Flint Aero, Inc. Airplane Flight Manual 

Supplement. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request To Remove Certain Steps From 

Appendix 1 

Dennis L. Hamblin from Flint Aero, 

Inc. stated that steps 11, 13, and 14 

should be removed from Appendix 1 of 

this AD. The inspection procedures in 

Appendix 1 are focused on damage 

caused by trimming of the close-out rib 

to allow passage of the fuel line. The 

Flint Aero, Inc. STC kit provides a 

close-out rib that replaces the Cessna 

close-out rib. This configuration allows 

for the passage of the fuel line. 

Additionally, the Flint Aero, Inc. STC 

kit provides reinforcement doublers for 

all added inspection openings/cutouts; 

therefore, there should be no 

unreinforced cutouts. 

We do not agree with the commenter. 

All steps in Appendix 1 are required to 

check for any damage to the affected 

close-out rib, spar cap, and cut-outs that 

may have been caused by an overload 

condition regardless of the STC 

installation configuration. 

We have not changed the final rule 

AD action based on this comment. 

Request To Incorporate Revised Service 

Information 

Flint Aero, Inc. issued a revision to 

Service Bulletin FA2 to correct a part 

number reference. We inferred that Flint 

Aero, Inc. wanted the FAA to include 

reference to the revised service bulletin 

into the final rule AD action. 

We agree. We have revised the final 

rule AD action to incorporate the 

revised service bulletin. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously 

and any minor editorial changes. We 

have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

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 33 

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 

Inspection of the wing for damage ........... 5 work-hours × $85 per hour = 

$425 per inspection cycle.

Not applicable ........ $425 per inspection 

cycle.

$14,025 per inspection cycle. 

Fabricating and installing placards in the 

cockpit.

1 work-hour × $85 per hour = 

$85.

Not applicable ........ $85 ......................... $2,805. 

Modifying the Limitations section of the 

Flint Aero, Inc. Airplane Flight Manual 

Supplement.

.5 work-hour × $85 per hour = 

$42.50.

Not applicable ........ $42.50 .................... $1,402.50. 

Reinforcing the upper wing skin, stringer, 

and wing front spar cap.

25 work-hours × $85 per hour = 

$2,125.

$1,070 .................... $3,195 .................... $105,435. 

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

Federal Register / Vol. 76, No. 147 / Monday, August 1, 2011 / Rules and Regulations 45659 

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.

Appendix 1 to AD 2011–15–11 

General and Focused Inspection Procedures 

Perform a general and focused inspection 

of the wing for internal and external damage 

from wing station (WSTA) 23 to the wing tip. 

The general inspection must be performed in 

accordance with 14 CFR 43.15(c), using a 

checklist that includes at least the scope and 

detail of the items contained in Appendix D 

of 14 CFR part 43. The focused inspection 

must include the items listed below. Remove 

all wing access panels to conduct the 

inspections. Do these inspections following 

the manufacturer’s service information and 

any other appropriate guidance, such as FAA 

Advisory Circular (AC) 43.13–1B Acceptable 

Methods, Techniques, and Practices— 

Aircraft Inspection and Repair. AC 43.13–1B 

can be found at http://rgl.faa.gov/. 

Focused inspection items to look for: 

(1) Wrinkles in upper wing skins, from the 

outboard edge on the fuel tank access covers 

(WSTA 150 or 177) to the WSTA 222 (See 

View B, Figure 3). 

(2) Wrinkles in the upper wing skins from 

WSTA 55 to 66, adjacent to the booms (See 

View E, Figure 6). 

(3) Cracking of the upper wing skins. Pay 

particular attention to any wrinkles, the 

radius between stiffeners at WSTA 150 

(under fuel tank covers), and unreinforced 

access holes (See View B, Figure 3). 

(4) Working (smoking) rivets outboard of 

the wing tank access covers. 

(5) Fasteners with less than two diameters 

edge distance. 

(6) Fasteners with less than four diameters 

center to center spacing. 

(7) Looseness of attachments of the tip 

extension to the wing and wing tip to wing 

extension when pushing up and down on the 

tip. 

(8) Any signs of distress along both front 

and rear spars, particularly in the area 

around WSTA 177. 

(9) Inspect under any repairs to the upper 

skins, particularly in the area just outboard 

of the fuel tank access covers as these may 

be covering up existing damage. 

(10) Inter-rivet buckling of the stringers 

attached to the upper surface skin, outboard 

of the fuel tank access covers (See View F, 

Figure 7). 

(11) Inspect rib at WSTA 222 for damage. 

Trimming of the rib may have been done to 

allow installation of fuel lines (See View A, 

Figure 2). Repair in accordance with AC 

43.13–1B, Chapter 4, paragraph 4–58(g) and 

Figure 4–14, or by using another FAAapproved method that restores equivalent 

strength of the wing rib. 

Appendix 1 to AD 2011–15–11 

General and Focused Inspection Procedures 

(Continued) 

(12) Inspect and identify screws, installed 

in tapped (threaded) holes in metal 

substructure, used to attach wing tips, stall 

fences, fuel and electrical components, and 

access doors. For tapped holes, remove 

fastener and open up the diameter to provide 

a smooth bore hole, for the smallest oversize 

fastener, using close tolerance holes noted in 

AC 43.13–1B, paragraph 7–39 or other FAAapproved scheme. Maintain minimum 2 x 

fastener diameter edge distance and 4 x 

fastener diameter center to center spacing. 

Select and install new, equivalent strength or 

stronger, fasteners with nuts/collars in 

accordance with AC 43.13–1B, Chapter 7 and 

AC 43.13–2B, paragraph 108 or other FAAapproved repair. New fasteners must not 

have threads in bearing against the sides of 

the holes. 

(13) Inspect wing skins for unreinforced 

cutouts. (See View C, Figure 4). 

(14) Inspect the upper spar cap horizontal 

flanges for open holes (See View D, Figure 5).
