BN2A, BN2B, and BN2A MKIII (all 

models on TCDS A17EU and A29EU) 

airplanes that would supersede AD 

2007–06–06. This proposed AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as cracks in the inner shell of 

certain pitot/static pressure heads. We 

are issuing this proposed AD to require 

actions to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by February 8, 2016.

Discussion 

On March 6, 2007, we issued AD 

2007–06–06, Amendment 39–14987 (72 

FR 12557; March 16, 2007). That AD 

required actions intended to address an 

unsafe condition on B–N Group Ltd. 

Models BN–2, BN–2A, BN–2A–2, BN– 

2A–3, BN–2A–6, BN–2A–8, BN–2A–9, 

BN–2A–20, BN–2A–21, BN–2A–26, BN

–2A–27, BN–2B–20, BN–2B–21, BN–2B

–26, BN–2B–27, BN2A MK. III, BN2A 

MK. III–2, BN2A MK. III–3 BN2A, 

BN2B, and BN2A MKIII (all models on 

TCDS A17EU and A29EU) airplanes and 

was based on mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country. 

Since we issued AD 2007–06–06, 

there are reports of premature failures of 

the affected part number (P/N) DU130– 

24 pitot-static probes. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No.: 

2015–0199, dated October 7, 2015 

(referred to after this as ‘‘the MCAI’’), to 

correct the above-referenced unsafe 

condition for the specified products. 

The MCAI states: 

In 2005, occurrences were reported of 

finding cracks in the inner shell of certain 

pitot/static pressure heads, Part Number 

(P/N) DU130–24. 

This condition, if not detected and 

corrected, could lead to incorrect readings on 

the pressure instrumentation, e.g. altimeters, 

vertical speed indicators (rate-of-climb) and 

airspeed indicators, possibly resulting in 

reduced control of the aeroplane. 

To address this potential unsafe condition, 

B–N Group issued Service Bulletin (SB) 310 

to provide inspection and test instructions. 

Consequently, CAA UK issued AD G–2005– 

0034 (EASA approval 2005–6447) to require 

repetitive inspections and leak tests and, 

depending on findings, accomplishment of 

applicable corrective action(s). 

Subsequently, B–N Group published SB 

310 issue 2, prompting EASA to issue AD 


tkelley on DSK3SPTVN1PROD with PROPOSALS
80292 Federal Register / Vol. 80, No. 247 / Thursday, December 24, 2015 / Proposed Rules 

2006–0143 making reference to SB 310 at 

issue 2, while the publication of BNA SB 310 

issue 3 prompted EASA AD 2006–0143R1, 

introducing BNA modification (mod) NB–M– 

1728 (new pitot/static pressure head not 

affected by the AD requirements) as optional 

terminating action for the repetitive 

inspections and leak tests. 

Since that AD was issued, operators have 

reported a number of premature failures of 

the affected P/N DU130–24 pitot-static 

probes. 

Prompted by these reports, BNA issued SB 

310 issue 4 to reduce the interval for the 

inspections and leak tests. 

For the reason described above, this AD 

retains the requirements of EASA AD 2006– 

0143R1, which is superseded, but requires 

those actions at reduced intervals. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2015–7777. 

Related Service Information Under 1 

CFR part 51 

B–N Group Ltd. has issued BrittenNorman Service Bulletin Number SB 

310, Issue 4, dated September 25, 2015. 

The service information describes 

procedures for inspections, and if 

necessary, replacement of the pitot/

static pressure head. 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 of this NPRM. 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between the Proposed AD 

and the MCAI 

The FAA has reviewed the MCAI and 

related service information and, in 

general, agree with their substance. The 

proposed AD does differ from the MCAI 

in that it does not reference BNA Mod 

NB–M–1728 as an optional terminating 

action for the repetitive inspections and 

leak tests. The FAA is unable to make 

these instructions reasonably available 

to interested parties so therefore we are 

unable to include this in the AD. After 

issuance of the final AD, the FAA will 

consider this modification as an 

alternative method of compliance 

(AMOC) to the AD provided it is 

submitted following the instructions in 

the AD and 14 CFR 39.19. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 93 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $7,905, or $85 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 2 work-hours and require parts 

costing $10,000, for a cost of $10,170 

per product. We have no way of 

determining the number of products 

that may need these actions. 

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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2014–16– 

02, for certain Bombardier, Inc. Model 

CL–600–1A11 (CL–600) airplanes. AD 

2014–16–02 currently requires revising 

the airplane flight manual to prohibit 

thrust reverser operation, doing 

repetitive detailed inspections of both 

engine thrust reversers for cracks, and 

modifying the thrust reversers if 

necessary. The modification of the 

thrust reversers is also an optional 

terminating action for the repetitive 

inspections. Since we issued AD 2014– 

16–02, we have determined that it is 

necessary to add a requirement to repair 

or modify the thrust reversers, which 

would terminate the requirements of AD 

2014–16–02. We are proposing this AD 

to detect and correct cracks of the 

translating sleeve at the thrust reverser 

actuator attachment points, which could 

result in deployment or dislodgement of 

an engine thrust reverser in flight and 

subsequent reduced control of the 

airplane.
