AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2012–24– 

06 for certain Saab AB, Saab 

Aeronautics (formerly known as Saab 

AB, Saab Aerosystems) Model 340A 

(SAAB/SF340A) and SAAB 340B 

airplanes. AD 2012–24–06 requires 

replacing the stall warning computer 

(SWC) with a new SWC, which provides 

an artificial stall warning in icing 

conditions, and modifying the airplane 

for the replacement of the SWC. Since 

we issued AD 2012–24–06, a 

determination was made that airplanes 

with certain modifications were 

excluded from the AD applicability and 

are affected by the identified unsafe 

condition and the SWC required by AD 

2012–24–06 contained erroneous logic. 

This proposed AD would 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. We are 

proposing this AD to prevent natural 

stall events during operation in icing 

conditions, which could result in loss of 

control of the airplane. 

DATES: We must receive comments on 

this proposed AD by February 1, 2016. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

On November 21, 2012, we issued AD 

2012–24–06, Amendment 39–17276 (77 

FR 73279, December 10, 2012). AD 

2012–24–06 applies to certain Saab AB, 

Saab Aerosystems Model 340A (SAAB/ 

SF340A) and SAAB 340B airplanes. AD 

2012–24–06 was prompted by reports of 

stall events during icing conditions 

where the natural stall warning (buffet) 

was not identified. AD 2012–24–06 

requires replacing the stall warning 

computer (SWC) with a new SWC, 

which provides an artificial stall 

warning in icing conditions, and 

modifying the airplane for the 

replacement of the SWC. We issued AD 

2012–24–06 to prevent natural stall 

events during operation in icing 

conditions, which, if not corrected, 

could result in loss of control of the 

airplane. 

Airplanes with certain modifications 

were excluded from the applicability of 

AD 2012–24–06, Amendment 39–17276 

(77 FR 73279, December 10, 2012). 

Since we issued AD 2012–24–06, we 

have determined that those 

modifications for airplanes identified in 

the applicability of AD 2012–24–06 are 

now subject to the identified unsafe 


Lhorne on DSK5TPTVN1PROD with PROPOSALS
78700 Federal Register / Vol. 80, No. 242 / Thursday, December 17, 2015 / Proposed Rules 

condition. In addition, a new, improved 

SWC has been designed to replace the 

existing SWC, as well as the SWC 

required by AD 2012–24–06. The 

installation of the new SWC includes 

modifying the airplane. 

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 for 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, 

Amendment 39–17276 (77 FR 73279, 

December 10, 2012)] 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. 

FAA’s Determination and Requirements 

of This 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 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. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

The applicability in the MCAI 

excludes airplanes which have been 

modified by Saab AB mod No. 2650 or 

mod No. 2859; however, this proposed 

AD does not exclude those airplanes 

because this proposed AD requires 

corrective actions for U.S. N-registered 

airplanes that have either modification 

installed. 

Paragraph (2) of the MCAI requires 

replacement of the existing SWCs 

within 18 months after the effective date 

of the MCAI. However, due to the 

urgency of the identified unsafe 

condition, we have determined that this 

replacement must be done within 12 

months after the effective date of this 

AD, as specified in paragraph (h) of this 

proposed AD. 

These differences have been 

coordinated with the EASA and Saab 

AB, Saab Aeronautics. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 105 airplanes of U.S. registry. 

We also estimate that it would take 

about 78 work-hours per product to 

comply with the actions required by this 

proposed AD. The average labor rate is 

$85 per work-hour. Required parts 

would cost about $33,000 per product. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 

operators to be $4,161,150, or $39,630 

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 


Lhorne on DSK5TPTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 242 / Thursday, December 17, 2015 / Proposed Rules 78701 

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
