We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 airplanes. This proposed AD was prompted by reports of main landing gear (MLG) access doors detaching from the airplane as a result of excessive vibration and metal fatigue in the attach fittings. This proposed AD would require modification of the MLG access door by replacing seals in the MLG fairing and, for certain airplanes, adding an additional bolt. We are proposing this AD to prevent a fracture in the MLG access door associated with excessive vibration and metal fatigue in the attach fittings. This condition could lead to MLG access door detachment and consequent impact of flight controls, resulting in reduced control of an airplane.

Airworthiness Directives; Airbus Defense and Space S.A. (Formerly 
Known as Construcciones Aeronauticas, S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 
airplanes. This proposed AD was prompted by reports of main landing 
gear (MLG) access doors detaching from the airplane as a result of 
excessive vibration and metal fatigue in the attach fittings. This 
proposed AD would require modification of the MLG access door by 
replacing seals in the MLG fairing and, for certain airplanes, adding 
an additional bolt. We are proposing this AD to prevent a fracture in 
the MLG access door associated with excessive vibration and metal 
fatigue in the attach fittings. This condition could lead to MLG access 
door detachment and consequent impact of flight controls, resulting in 
reduced control of an airplane.

DATES: We must receive comments on this proposed AD by May 31, 2016.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued 
Airworthiness Directive 2015-0225, dated November 18, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness

[[Page 21767]]

Information, or ``the MCAI''), to correct an unsafe condition for 
certain Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-
235-300 airplanes. The MCAI states:

    Occurrences of Main Landing Gear (MLG) Access Door detachment 
were reported. Subsequent investigation determined that the 
detachments of the MLG Door occurred during maneuvers performed at 
high speed and with high sideslip angle on airplanes not modified in 
accordance with the instructions EADS-CASA [European Aeronautic 
Defence and Space Company-Construcciones Aeronauticas, S.A]. Service 
Bulletins (SBs) SB-235-52-0061 and SB-235-52-0068. Based on the 
investigation results, it was determined that the fracture mechanism 
was associated with excessive deformation that could produce 
scooping in the forward edge combined with an excessive vibration of 
the MLG Access Door.
    This condition, if not corrected, could lead to MLG Access Door 
detachment and consequent impact of flight controls, resulting in 
reduced control of an airplane and possible injury of persons on the 
ground.
    To address this potential unsafe condition, EADS-CASA issued SB-
235-52-0061 and SB-235-52-0068 to provide modification instructions.
    For the reasons described above, this [EASA] AD requires 
modification of MLG Access Doors and prohibits installation of a MLG 
Access Door sealing part number (P/N) CAN36032R. This AD also 
prohibits installation of not modified MLG Access Doors.

    Required actions include modification of the MLG access door by 
replacing seals in the MLG fairing and, for certain airplanes, adding 
an additional bolt. 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-2016-5467.

Related Service Information Under 1 CFR Part 51

    EADS CASA has issued the following service information:
     EADS CASA Service Bulletin SB-235-52-0061, Revision 1, 
dated October 24, 2014. The service information describes procedures 
for modifying the MLG access door by installing an additional bolt.
     EADS CASA Service Bulletin SB-235-52-0068, Revision 2, 
dated January 9, 2015. The service information describes procedures for 
modifying the MLG access door by installing an improved fairing seal.
    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 30 airplanes of U.S. 
registry.
    We also estimate that it will take up to 60 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 up to 
$12,684 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $533,520, or up to $17,784 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
