**DEPARTMENT OF TRANSPORTATION**

**Federal Aviation Administration**

**14 CFR Part 39**

**[Docket No. FAA–2014–0172; Directorate Identifier 2013–NM–222–AD; Amendment**  **39–17929; AD 2014–16–05]**

**RIN 2120–AA64**

**Airworthiness Directives; Embraer S.A. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by reports of ‘‘BLEED 1(2) LEAK’’ messages displayed on the engine indication and crew alert system (EICAS), and indirect damage to components of the electrical wiring interconnection system (EWIS) in the engine pylon area. This AD requires inspecting the EWIS components for damage, and repair if necessary. This AD also requires installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are issuing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.

**DATES :**  This AD is effective October 2,

2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 2, 2014.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Embraer S.A. Model ERJ 170 airplanes. The NPRM published in
the Federal Register on March 28, 2014 (79 FR 17461).

The Age ˆ ncia Nacional de Aviac

 ̧ a  ̃ o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2013–11–01, effective November 4, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Embraer S.A. Model ERJ 170 airplanes. The MCAI states:

This [Brazilian] AD results from reports of ‘‘BLEED 1(2) LEAK’’ messages being displayed on the Engine Indication and Crew Alert system (EICAS) panel, and indirect damages to components of the Electrical Wiring Interconnection System (EWIS) on the engine pilone area, zones 419 and 429, adjacent to the exhaust flange of the engine bleed air precooler.

Further investigation has shown that a leakage on the flange of the precooler refrigerating air exhaust duct caused the damage and triggered the message. We are issuing this [Brazilian] AD to prevent EWIS components indirect damage, near to engine bleed air precooler, which could result in a dual engine roll back to idle and the consequent dual engine power loss.

Required actions include inspecting the EWIS components adjacent to the left- and right-hand pre-cooler for damage, and repair if necessary; installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. You may
examine the MCAI in the AD docket on
the Internet at http:// www.regulations.gov/ #!docketDetail;D=FAA-2014-0172-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 17461, March 28, 2014) 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 AD with the changes described previously and minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (79 FR 17461, March 28, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 17461, March 28, 2014).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Costs of Compliance

We estimate that this AD affects 181 airplanes of U.S. registry.

We also estimate that it takes 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 cost about $366 per product. Based on these figures, we
estimate the cost of the AD on U.S. operators to be $158,556, or $876 per product.

We have received no definitive data that would enable us to provide cost
estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I,


### 51230 Federal Register / Vol. 79, No. 167 / Thursday, August 28, 2014 / Rules and Regulations

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

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 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.

the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0172; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Dassault Aviation Model FALCON 7X airplanes. The NPRM published in the Federal Register on March 25, 2014 (79 FR 16239). The NPRM was prompted by reports that the pintle pins installed on a certain number of airplanes may be incorrectly protected against corrosion. The NPRM proposed to require replacing certain pintle pins on the left- and right-hand main landing gear (MLG) with a serviceable part. We are issuing this AD to detect and correct pintle pins thathave been incorrectly corrosionprotected, which could cause the pintle pins to shear under normal load and lead to the collapse of the MLG during take-off or landing.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0162, dated July 24, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition
all Dassault Aviation Model FALCON 7X airplanes. The MCAI states:

Messier-Bugatti-Dowty, the manufacturer of the landing gears of the Falcon 7X aeroplanes, has advised that pintle pins Part Number (P/N) 55–2355007–01 being installed on a certain number of aeroplanes may be incorrectly protected against corrosion. These pins are designed to shear in case of excessive loads on the main landing gears so that structural damage would be containedafter a landing gear collapse. The cadmiumcoating inside the bore of suspect pins may not be compliant to the original thickness specifications. Inspection of a few removed parts in service revealed that traces of limited
corrosion can be found on an unstressed area of the pins. Messier-Bugatti-Dowty identified a list of potentially affected pintle pins and subsequently, Dassault Aviation identified on which aeroplanes those pintle pins were
installed.

This condition, if not corrected, may lead to corrosion of the pins and ultimately cause
them to shear under normal load. This could result in landing gear collapse during take-off or landing.

To address this condition, DassaultAviation, with the support of MessierBugatti-Dowty, developed Service Bulletin (SB) F7X–182 to provide instructions for removal of potentially affected pintle pins and replacement with serviceable parts.

For the reasons described above, this [EASA] AD requires replacement of pintle pins on affected airplanes. This [EASA] AD
