Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2015–07, 

dated April 28, 2015 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model 


asabaliauskas on DSK5VPTVN1PROD with PROPOSALS
Federal Register / Vol. 81, No. 8 / Wednesday, January 13, 2016 / Proposed Rules 1587 

DHC–8–401 and -402 airplanes. The 

MCAI states: 

During endurance and impulse testing of 

the spoiler PCU, cracks were discovered on 

two test spoiler PCU manifolds. Investigation 

determined that the crack initiation was due 

to the heat treat process. A cracked spoiler 

PCU manifold could cause the loss of one of 

the two hydraulic systems, resulting in the 

loss of multiple flight controls and landing 

gear systems. This condition, if not corrected, 

could adversely affect the continued safe 

operation and landing of the aeroplane. 

This [Canadian] AD mandates the 

replacement of the affected spoiler PCUs. 

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– 

8434. 

Related Service Information Under 

1 CFR Part 51 

Bombardier, Inc. has issued 

Bombardier Service Bulletin 84–27–64, 

dated July 15, 2014. The service 

information describes procedures for 

identification and replacement of 

affected spoiler PCU manifolds. 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 the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

affects 82 airplanes of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $10,000 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $833,940, or 

$10,170 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 

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.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2015–0129, dated July 6, 2015 

(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: 

There have been some reported events of 

ruptured horizontal stabilizer de-icing boots. 

In-flight rupture of a de-icing boot will result 

in complete loss of the de-icing function 

within its associated zone. In addition, in 

some of these events, the de-icing boot had 

formed a large open scoop. 

This condition, if not detected and 

corrected, could lead to severe vibrations, 

possibly resulting in reduced control of the 

aeroplane. 

To address this potential unsafe condition, 

SAAB issued Alert Operations Bulletin 

(AOB) No.12 and AOB No. 23 as a temporary 

measure, recommending performing a flap 0 

landing in the event of a suspected rupture 

of the de-icing boot on the horizontal 

stabilizer. 

In addition, SAAB issued SB 340–30–094 

to provide instructions to inspect the affected 

de-icing boots. 

For the reasons described above, this 

[EASA] AD requires an amendment of the 

applicable Airplane Flight Manual (AFM) 

and, pending the development of a 

modification by SAAB, repetitive inspections 

of the horizontal stabilizer de-icing boots 

and, depending on findings, accomplishment 

of applicable corrective action(s). 

This [EASA] AD is considered to be an 

interim action and further AD action may 

follow.
