14 CFR Part 39

[Docket No. FAA-2015-0250; Directorate Identifier 2014-NM-216-AD; 
Amendment 39-18505; AD 2016-09-07]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A318, A319, A320, and A321 series airplanes. This AD was 
prompted by reports of airspeed indication discrepancies while flying 
at high altitudes in inclement weather. This AD requires replacing 
certain pitot probes on the captain, first officer, and standby sides 
with certain new pitot probes. We are issuing this AD to prevent 
airspeed indication discrepancies during inclement weather, which, 
depending on the prevailing altitude, could lead to unknown 
accumulation of ice crystals and consequent reduced controllability of 
the airplane.

DATES: This AD is effective June 10, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 10, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) 
(``the SNPRM'') to amend 14 CFR part 39 for all Airbus Model A318, 
A319, A320, and A321 series airplanes. The SNPRM published in the 
Federal Register on December 23, 2015 (80 FR 79750). We preceded the 
SNPRM with a notice of proposed rulemaking (NPRM) (``the NPRM'') that 
published in the Federal Register on March 6, 2015 (80 FR 12094). The 
NPRM proposed to require replacing certain pitot probes on the captain, 
first officer, and standby sides with certain new pitot probes. The 
NPRM was prompted by reports of airspeed indication discrepancies while 
flying at high altitudes in inclement weather. The SNPRM proposed to 
revise the NPRM by reducing the proposed compliance time for replacing 
certain pitot probes based on a risk assessment due to additional 
reports of airspeed indication discrepancies while flying at high 
altitudes in inclement weather. We are issuing this AD to prevent 
airspeed indication discrepancies during inclement weather, which, 
depending on the prevailing altitude, could lead to unknown 
accumulation of ice crystals and consequent reduced controllability of 
the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, issued EASA 
Airworthiness Directive 2015-0205, dated October 9, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318, A319, A320, and A321 series airplanes. The MCAI states:

    Occurrences have been reported on A320 family aeroplanes of 
airspeed indication discrepancies while flying at high altitudes in 
inclement weather conditions. Investigation results indicated that 
A320 aeroplanes equipped with Thales Avionics Part Number (P/N) 
50620-10 or P/N C16195AA pitot probes appear to have a greater 
susceptibility to adverse environmental conditions that aeroplanes 
equipped with certain other pitot probes.
    Prompted by earlier occurrences, DGAC [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] France issued [DGAC] AD 
2001-362 [<a href="http://ad.easa.europa.eu/ad/F-2001-362">http://ad.easa.europa.eu/ad/F-2001-362</a>] [which corresponds 
to paragraph (f) of FAA AD 2004-03-33, Amendment 39-13477 (69 FR 
9936, March 3, 2004)] to require replacement of Thales (formerly 
known as Sextant) P/N 50620-10 pitot probes with Thales P/N C16195AA 
probes.
    Since that [DGAC] AD was issued, Thales pitot probe P/N C15195BA 
was designed, which improved airspeed indication behavior in heavy 
rain conditions, but did not demonstrate the same level of 
robustness to withstand high-altitude ice crystals. Based on these 
findings, EASA have decided to implement replacement of the affected 
Thales [pitot] probes as a precautionary measure to improve the 
safety level of the affected aeroplanes.
    Consequently, EASA issued AD 2014-0237 (later revised) [<a href="http://ad.easa.europa.eu/blob/easa_ad_2014_0237.pdf/AD_2014-0237">http://ad.easa.europa.eu/blob/easa_ad_2014_0237.pdf/AD_2014-0237</a>], 
retaining the requirements of DGAC France AD 2001-362, which was 
superseded, and cancelling two other DGAC ADs, to require 
replacement of Thales Avionics pitot probes P/N C16195AA and P/N 
C16195BA.
    Since EASA issued AD 2014-0237R1 [<a href="http://ad.easa.europa.eu/ad/2014-0237R1">http://ad.easa.europa.eu/ad/2014-0237R1</a>] was issued, results of further analyses have determined 
that the compliance time (48 months) of that AD has to be reduced in 
relation to the risk assessment.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0237R1, which is superseded, but 
reduces the compliance time.

    You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2015-
0250.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. United Airlines has no 
objection to the SNPRM.

[[Page 27299]]

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Airbus service information:
    <bullet> Airbus Service Bulletin A320-34-1170, Revision 30, dated 
June 18, 2015.
    <bullet> Airbus Service Bulletin A320-34-1456, Revision 01, dated 
May 15, 2012.
    <bullet> Airbus Service Bulletin A320-34-1463, Revision 01, dated 
May 15, 2012.
    The service information describes procedures for replacing certain 
Thales Avionics pitot probes on the captain, first officer, and standby 
sides. 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.

Costs of Compliance

    We estimate that this AD affects 953 airplanes of U.S. registry.
    We also estimate that it takes about 4 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $21,930 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $21,223,310, or $22,270 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 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 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.
