SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2016–13–06, 

Amendment 39–18570 (81 FR 41432, 

June 27, 2016) (‘‘AD 2016–13–06’’). AD 

2016–13–06 applied to certain Saab AB, 

Saab Aeronautics Model 340A (SAAB/ 

SF340A) and SAAB 340B airplanes. The 

NPRM published in the Federal 

Register on April 17, 2018 (83 FR 

16792). The NPRM was prompted by 

reports of ruptured horizontal stabilizer 

de-icing boots. The NPRM proposed to 

continue to require a revision of the 

applicable AFM, repetitive inspections 

of the horizontal stabilizer de-icing 

boots, and applicable corrective actions. 

The NPRM also proposed to require 

replacement of single stitched de-icing 

boots with improved double stitched 

boots, and re-identification of the 

modified horizontal stabilizer leading 

edge. We are issuing this AD to detect 

and correct ruptured horizontal 

stabilizer de-icing boots, which could 

lead to complete loss of the de-icing 

function within its associated zone and 

severe vibrations, possibly resulting in 

reduced control of the airplane. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2017–0144, 

dated August 9, 2017 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Saab AB, Saab Aeronautics 

Model 340A (SAAB/SF340A) and SAAB 

340B airplanes. The MCAI states: 

Several occurrences were reported of 

rupture of the horizontal stabilizer de-icing 

boot in flight. In some of the reported events, 

the de-icing boot had formed a large open 

scoop. 

This condition, if not detected and 

corrected, could lead to complete loss of the 

de-icing function within its associated zone 

and severe vibrations, possibly resulting in 

reduced control of the aeroplane. 

To address this potential unsafe condition, 

Saab AB, Aeronautics (hereafter referred to as 

‘‘Saab’’ in this [EASA] AD) issued Alert 

Operations Bulletin (AOB) No. 12 and AOB 

No. 23 as temporary measures, 

recommending to select Flaps 0 for landing 

in the event of a suspected rupture of the 

deicing boot on the horizontal stabilizer. In 

addition, Saab issued SB [Service Bulletin] 

340–30–094 providing instructions for 

inspection of de-icing boots. 

Consequently, EASA issued AD 2015–0129 

[which corresponds to FAA AD 2016–13–06] 

to require amendment of the applicable 

Aircraft Flight Manual (AFM), repetitive 

inspections of the horizontal stabilizer 

deicing boots and, depending on findings, 

accomplishment of applicable corrective 

action(s). 

Since that [EASA] AD was issued, Saab 

developed an improved de-icing boot, 

reinforced through double stitch lines, and 

issued SB 340–30–095 providing instructions 

for boot replacement. 

For the reason described above, this 

[EASA] AD retains the requirements of EASA 

AD 2015–0129, which is superseded, and 

requires replacement of single stitched 

deicing boots, installed on the left-hand (LH) 

and right-hand (RH) horizontal stabilizer, 

with improved double stitched boots, and 

reidentification of the modified horizontal 

stabilizer leading edge. 

You may examine the MCAI in the 

AD docket on the internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0271. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

We received no comments on the NPRM 

or on the determination of the cost to 

the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. We have determined 

that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Saab AB, Saab Aeronautics has issued 

the following service information. 

• Service Bulletin 340–30–094, dated 

March 27, 2015. This service 

information describes procedures for 

repetitive detailed inspections of the deicing boots installed on the horizontal 

stabilizers, and repair and replacement 

of damaged de-icing boots. 

• Service Bulletin 340–30–095, dated 

April 3, 2017. This service information 

describes procedures for replacement of 

single stitched de-icing boots with 

improved double stitched boots, and reidentification of the modified horizontal 

stabilizer leading edge. 

Saab AB, Saab Aeronautics has also 

issued the following AFMs, which 

describe performance limitations and 

general data. These AFMs are distinct 

since they apply to different airplane 

models in different configurations. 

• AFM 340A 001, Revision 57, dated 

March 27, 2015. 

• AFM 340B 001, Revision 35, dated 

March 27, 2015. 

• AFM 340B 010, Revision 28, dated 

March 27, 2015. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

Costs of Compliance 

We estimate that this AD affects 51 

airplanes of U.S. registry. 

The actions required by AD 2016–13– 

06, and retained in this AD take about 

6 work-hours per product, at an average 

labor rate of $85 per workhour. Based 

on these figures, the estimated cost of 

the actions that are required by AD 

2016–13–06 is $510 per product. 


daltland on DSKBBV9HB2PROD with RULES
Federal Register / Vol. 83, No. 178 / Thursday, September 13, 2018 / Rules and Regulations 46379 

In addition, we estimate that any 

necessary follow-on actions required by 

AD 2016–13–06, and retained in this AD 

take about 6 work-hours and require 

parts costing $9,500, for a cost of 

$10,010 per product. We have no way 

of determining the number of aircraft 

that might need these actions. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts would 

cost about $13,500 per product. Based 

on these figures, we estimate the cost of 

this AD on U.S. operators to be 

$714,510, or $14,010 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to transport category 

airplanes to the Director of the System 

Oversight Division. 

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 that 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); 

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.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–100, –200, 

–200C, –300, –400, and –500 series 

airplanes. This AD was prompted by 

reports of cracking in certain flanges, 

and the adjacent web, of the wing 

outboard flap track at certain positions, 

and a determination that new 

inspections of certain flap track flanges 

and webs forward of the rear spar 

attachment are necessary. This AD 

requires an inspection to determine the 

part number of the wing outboard flap 

track assembly; repetitive inspections of 

each affected wing outboard flap track 

for discrepancies, and applicable oncondition actions; and repetitive 

overhaul of each wing outboard flap 

track. We are issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective October 18, 

2018. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 18, 2018.
