Airworthiness Directives; Saab AB,

Saab AB, Saab Aerosystems) 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Saab AB, Saab Aeronautics 

Model 340A (SAAB/SF340A) and SAAB 

340B airplanes. The NPRM proposed to 

supersede AD 2012–24–06. AD 2012– 

24–06 currently requires replacing the 

stall warning computer (SWC) with a 

new SWC that provides an artificial stall 

warning in icing conditions, and 

modifying the airplane for the 

replacement of the SWC. The NPRM 

was prompted by a determination that 

airplanes with certain modifications 

were excluded from the applicability in 

AD 2012–24–06, and are affected by the 

identified unsafe condition; and the 

SWC required by AD 2012–24–06 

contained erroneous logic. This action 

revises the NPRM by reducing the 

compliance time for replacing the 

SWCs. We are proposing this 

supplemental NPRM (SNPRM) to 

prevent natural stall events during 

operation in icing conditions, which 

could result in loss of control of the 

airplane. Since this compliance time 

reduction imposes an additional burden 

to operators, we are reopening the 

comment period to allow the public the 

chance to comment on these proposed 

changes. 

DATES: We must receive comments on 

this SNPRM by August 26, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Saab AB, Saab 

Aeronautics Model 340A (SAAB/

SF340A) and SAAB 340B airplanes. The 

NPRM published in the Federal 

Register on December 17, 2015 (80 FR 

78699) (‘‘the NPRM’’). The NPRM 

proposed to supersede AD 2012–24–06, 

Amendment 39–17276 (77 FR 73279, 

December 10, 2012) (‘‘AD 2012–24– 

06’’). AD 2012–24–06 currently requires 

replacing the SWC with a new SWC that 

provides an artificial stall warning in 

icing conditions, and modifying the 

airplane for the replacement of the 

SWC. The NPRM was prompted by a 

determination that airplanes with 

certain modifications were excluded 

from the applicability in AD 2012–24– 

06, and are affected by the identified 

unsafe condition; and the SWC required 

by AD 2012–24–06 contained erroneous 

logic. The NPRM proposed to add 

airplanes to the applicability, and 

would add requirements to replace the 

existing SWCs with new, improved 

SWCs and modify the airplane for the 

new replacement of the SWC. 

Actions Since Previous NPRM Was 

Issued 

Since we issued the NPRM, we have 

determined that the compliance time for 

replacing the SWCs must be reduced to 

ensure the unsafe condition is 

addressed prior to the beginning of icing 

season after publication of the AD. We 

have determined that parts are available 

to support the reduced compliance time. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2014–0218, dated September 

29, 2014 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition on certain Saab AB, 

Saab Aeronautics Model 340A (SAAB/

SF340A) and SAAB 340B airplanes. The 

MCAI states: 

A few natural stall events, specifically 

when operating in icing conditions, have 

been experienced on SAAB 340 series 

aeroplanes, without receiving a prior stall 

warning. 

This condition, if not corrected, could 

result in loss of control of the aeroplane. 

To address this potential unsafe condition, 

SAAB developed a modified stall warning 

system, incorporating improved stall warning 

logic, and issued Service Bulletin (SB) 340– 

27–098 and SB 340–27–099, providing 

instructions to replace the Stall Warning 

Computer (SWC) with a new SWC, and 

instructions to activate the new SWC. The 

new system included stall warning curves 

optimized for operation in icing conditions, 

which are activated by selection of Engine 

Anti-Ice. 

Consequently, EASA issued AD 2011–0219 

[http://ad.easa.europa.eu/ad/2011-0219, 

which corresponds to FAA AD 2012–24–06] 

to require installation of the improved SWC. 

After that [EASA] AD was issued, inservice experience with the improved stall 

warning system revealed cases of premature 

stall warning activation during the take-off 

phase. In numerous recorded cases, the onset 

of stall warning occurred without the 6 

minute delay after weight off wheels. 

This condition, if not corrected, could lead 

to premature stick shaker activation and 

consequent increase in pilot workload during 

the take-off phase, possibly resulting in 

reduced control of the aeroplane. 

To correct this unsafe condition, EASA 

issued AD 2013–0254 [http://

ad.easa.europa.eu/ad/2013-0254] retaining 

the requirements of EASA AD 2011–0219, 

which was superseded, to require 

deactivation of the ice speed curves in the 

improved SWC on SAAB 340 aeroplanes, in 

accordance with SAAB SB 340–27–116. 

Since EASA AD 2013–0254 was issued, 

SAAB developed a technical solution to 

eliminate the premature activation of the stall 

warning ice curves and issued SB 340–27– 

120 (modification of the existing Stall 

Warning System installation), SB 340–27– 

121 (activation of improved SWC for 

aeroplanes with a basic wing tip) and SB 

340–27–122 (activation of improved SWC for 

aeroplanes with an extended wing tip). 

SAAB SB 340–27–120 provides modification 

and installation instructions valid for preand post-SB 340–27–097, 340–27–098, SB 

340–27–099 and SB 340–27–116 aeroplanes. 

For aeroplanes modified in accordance with 

SAAB AB mod. No. 2650 and/or mod. No. 

2859 which are no longer registered in 

Canada, SAAB AB issued SAAB AB SB 340– 

27–109 to provide modification and 

installation instructions to remove the ice 

speed curve function. 

For the reasons described above, this 

[EASA] AD retains the requirements of EASA 

AD 2013–0254, which is superseded, and 

requires modification of the Stall Warning 

and Identification System and replacement of 

the SWC with an improved unit. 

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–2015– 

6544. 

Related Service Information Under 1 

CFR Part 51 

Saab AB, Saab Aeronautics has issued 

the following service information: 

• Saab Service Bulletin 340–27–109, 

dated April 14, 2014. 

• Saab Service Bulletin 340–27–116, 

dated October 18, 2013. 

• Saab Service Bulletin 340–27–120, 

dated July 11, 2014. 

• Saab Service Bulletin 340–27–121, 

dated July 11, 2014. 

• Saab Service Bulletin 340–27–122, 

dated July 11, 2014. 

The service information describes 

procedures for deactivating the stall 

warning speed curves in the SWCs for 

certain airplanes; replacing the existing 

SWCs with new, improved SWCs; and 

modifying the airplane for the new 

replacement of the SWC. 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. 

Comments 

We gave the public the opportunity to 

participate in developing this proposed 

AD. We considered the comments 

received. 

Request To Reduce Compliance Time 

Saab asked that the compliance time 

in paragraph (h) of the proposed AD (in 

the NPRM) for replacement of the SWC 

be reduced from 12 to 3 months. Saab 

stated that a global alternative method 

of compliance (AMOC) was issued by 

the FAA on September 4, 2014, with a 

compliance time of 18 months; 

therefore, operators should have 

scheduled replacement of the SWCs 

after the AMOC was issued. Saab also 

stated that the MCAI required 

compliance within 18 months after 

September 29, 2014, and that time has 

expired. Saab added that reducing the 

compliance time to 3 months is more in 

line with the MCAI. In addition, Saab 

noted that all operators have ordered 

replacement SWCs, and Saab has those 

parts in stock and ready for delivery. 

We agree with the commenter’s 

request to reduce the compliance time, 

for the reasons provided. We also note 

that reducing the compliance time will 

ensure that new SWCs are installed 

before the icing season begins. We have 

changed the compliance time in 

paragraph (h) of this proposed AD from 

12 to 3 months accordingly.

45074 Federal Register / Vol. 81, No. 133 / Tuesday, July 12, 2016 / Proposed Rules 

Request To Correct Email Address 

Saab asked that the Saab email 

address in the proposed AD (in the 

NPRM) be corrected to specify the 

following: saab340.techsupport@

saabgroup.com. 

We agree with the commenter’s 

request. The email address for Model 

SAAB 2000 airplanes was inadvertently 

cited in the NPRM. We have corrected 

the address in the ADDRESSES section 

and in paragraph (l)(2) of this proposed 

AD. 

Request To Use Later Revisions of 

Service Information 

Silver Airways asked if we could 

include subsequent revisions of the 

referenced service information for AD 

2012–24–06. 

We do not agree with the commenter’s 

request because this proposed AD does 

not require the service information 

referenced in AD 2012–24–06. This 

proposed AD does refer to the latest 

available service information for the 

proposed actions. Referring to a specific 

service bulletin in an AD and using the 

phrase ‘‘or later FAA-approved 

revisions’’ violates Office of the Federal 

Register regulations for approving 

materials that are incorporated by 

reference. However, operators may 

request approval to use a later revision 

of the referenced service information as 

an AMOC under the provisions of 

paragraph (k)(1) of this proposed AD. 

We have not changed this final rule 

regarding this issue. 

FAA’s Determination and Requirements 

of This SNPRM 

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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of these same 

type designs. 

Certain changes described above 

expand the scope of the NPRM. As a 

result, we have determined that it is 

necessary to reopen the comment period 

to provide additional opportunity for 

the public to comment on this SNPRM. 

Costs of Compliance 

We estimate that this SNPRM affects 

105 airplanes of U.S. registry. 

The actions that are required by AD 

2012–24–06, and retained in this 

SNPRM, take about 78 work-hours per 

product, at an average labor rate of $85 

per work-hour. Required parts cost 

about $33,000 per product. Based on 

these figures, the estimated cost of the 

actions that are required by AD 2012– 

24–06 is $39,630 per product. 

The new requirement of this SNPRM 

adds no additional economic burden. 

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); 

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

safety, Incorporation by reference, 

Safety. 

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 Airworthiness Directive (AD) 

2012–24–06, Amendment 39–17276 (77 

FR 73279, December 10, 2012), and 

adding the following new AD:

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–100, 

–200, and –200C series airplanes. This 

proposed AD is intended to complete 

certain mandated programs intended to 

support the airplane reaching its limit of 

validity (LOV) of the engineering data 

that support the established structural 

maintenance program. This proposed 

AD would require repetitive detailed, 

high frequency eddy current (HFEC), 

and ultrasonic inspections of the center 

section rear spar upper clevis lugs and 

horizontal stabilizer rear spar upper 

lugs, as applicable, for any cracking, and 

related investigative and corrective 

actions if necessary. For certain 

airplanes, this proposed AD would 

require replacement of the center 

section rear spar upper chord with a 

new part and a serviceable center 

section assembly. This proposed AD 

would also require repetitive HFEC and 

fluorescent dye penetrant inspections of 

the center section for cracking of the 

front and rear spar upper clevis lugs or 

horizontal stabilizer front and rear spar 

upper lugs, and related investigative 

and corrective actions if necessary. We 

are proposing this AD to detect and 

correct cracking in the rear spar upper 

clevis lugs of the center section, and in 

the rear spar upper lugs of the 

horizontal stabilizer which could result 

in the loss of structural integrity and 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 26, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
