14 CFR Part 39

[Docket No. FAA-2011-0360; Directorate Identifier 2010-CE-061-AD; 
Amendment 39-17023; AD 2012-08-06]
RIN 2120-AA64

Airworthiness Directives; Univair Aircraft Corporation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Univair Aircraft Corporation Models (ERCO) 415-C, 415-CD, 
415-D, E, G; (Forney) F-1 and F-1A; (Alon) A-2 and A2-A; and (Mooney) 
M10 airplanes. That AD currently requires an inspection of the aileron 
balance assembly and ailerons for cracks and excessive looseness of 
associated parts with the required repair or replacement of defective 
parts as necessary. This new AD would add airplanes to the 
Applicability section; require inspections of the ailerons, aileron 
balance assembly, and aileron rigging for looseness or wear, require 
repair or replacement of parts as necessary; and require a report of 
the inspection results. This new AD was prompted by a report of a 
Univair Aircraft Corporation Model ERCO 415-D Ercoupe that crashed 
after an in-flight

[[Page 52206]]

breakup due to possible aileron flutter. We are issuing this AD to 
correct the unsafe condition on these products.

DATES: This AD is effective October 3, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of October 3, 
2012.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 52-02-02 (21 FR 9447, December 4, 1956). That 
AD applies to the specified products. The NPRM published in the Federal 
Register on April 14, 2011 (76 FR 20894, April 14, 2011). That NPRM 
proposed to add airplanes to the Applicability section; require 
inspections of the ailerons, aileron balance assembly, and aileron 
rigging for looseness or wear; repair or replacement of parts as 
necessary; and require a report of the inspection results.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(76 FR 20894, April 14, 2011) and the FAA's response to each comment.

Request To Withdraw NPRM or Change the Inspection Interval

    William R. Bayne and Hartmut Beil stated that the service bulletin 
and/or the manufacturer's existing recommendations, such as lubricating 
control rod ends at 300 hour intervals, are adequate, and the existing 
AD 52-02-02 (21 FR 9447, December 4, 1956) is sufficient. They stated 
that the number of in-flight breakups do not identify a failure of the 
flight control system and do not justify the need for AD action. They 
also stated the inspection interval should be 300 hours instead of 100 
hours to match the existing recommendations, and the proposed AD puts a 
financial burden on owners with little or no gain for safety.
    We disagree with these comments. This AD will add airplanes to the 
Applicability section that were not included in AD 52-02-02 (21 FR 
9447, December 4, 1956). Also, the flight control free play limits can 
vary or be out of tolerance for many more reasons than not doing the 
300-hour lubrication requirement. Also, varying field reports indicated 
that the majority of flight control systems are not in tolerance. In 
addition, Ercoupe Service Memorandum No. 57, Revision A, dated 
September 1, 2008, recommends free play inspection every 100 hours.

Request To Allow for Credit for the Calibration of the Airspeed 
Indicator

    Linda Abrams requested we change the calibration of the airspeed 
indicator (ASI) requirement, paragraph (g)(8) of the proposed AD (76 FR 
20894, April 14, 2011), to allow for ``unless already done'' credit 
since that applies to the other inspection requirements, and it would 
impose a financial burden on owners and operators.
    We agree. ``Unless already done'' credit will be applied for the 
ASI calibration requirement in paragraph (g)(8) of this AD as all other 
``unless already done'' credit is being applied by reference to the 
Compliance section, paragraph (f) of this AD.

Request To Reference Mooney M-10 Service and Maintenance Manual

    James E. Dyer of Univair requested the Mooney M-10 service and 
maintenance requirements be addressed by separate applicable service 
information since the Ercoupe Service Memorandum No. 57 and 35A, both 
Revisions A, both dated September 1, 2008, are not applicable to the 
Mooney M-10.
    We agree. We revised the ``Required Actions'' section paragraph (g) 
of this AD by adding text that requires inspecting and taking 
corrective action on the Mooney M-10 flight control system per pages 5-
1 through 5-4 of the Mooney M-10 Service and Maintenance Manual, Serial 
Numbers 690001 through 690011 and 700001 and on, Revision A, dated 
September 1, 2008. We also added Ercoupe Service Memorandum No. 35A, 
Revision A, dated September 1, 2008, to the applicable service 
information, and added an area to the reporting requirement pertaining 
to the use of Ercoupe Service Memorandum No. 35A, Revision A, dated 
September 1, 2008.

Request To Reference Ercoupe Service Bulletin No. 20 for the Aileron 
Balance Assembly Requirements

    James E. Dyer commented that Ercoupe Service Memorandum No. 20, 
Revision A, dated September 1, 2008, is only referenced in the one-time 
reporting requirement of the ``Required Actions'' section, paragraph 
(g) of the proposed AD and not referenced as a procedural requirement 
for the inspection of ailerons with counter weights.
    We agree. We have revised this AD by adding Ercoupe Service 
Memorandum No. 20, Revision A, dated September 1, 2008, as a reference 
in the ``Required Actions'' section, paragraph (g), of this AD 
pertaining to airplanes with the aileron balance assembly (ERCO part 
number (P/N) 415-16009).

Request To Require the Airspeed Indicator Calibration To Be Done at an 
Instrument Repair Facility

    James E. Dyer, Linda T. Abrams, and Jack Chmiel commented that the 
calibration test for the ASI should be completed by an authorized 
instrument repair facility because Advisory Circular AC 23-8B, Appendix 
9 contains technical requirements that exceed the ability of most 
owner/operators, repair stations, or Airframe & Powerplant (A&P) 
mechanics on this class of airplane.
    We partially agree. We have revised the ``Required Actions'' 
section, paragraph (g)(8) of this AD to require an FAA-authorized 
instrument repair facility to calibrate the ASI if the bench test 
method is used. However we will allow an exception for global 
positioning system (GPS) or other owner/operator FAA-approved methods 
of calibrating the ASI following the instructions in FAA Advisory 
Circular AC 23-8C, Appendix 9, dated

[[Page 52207]]

November 16, 2011. These procedures will be repetitively required every 
4 years and any time maintenance affects the system integrity.

Request To Make the Reporting Requirement a One-Time Action

    Jack Chmiel, William R. Bayne, and an anonymous commenter stated 
they did not think the Inspection Report should be submitted after each 
inspection interval. They didn't feel the referenced report was clearly 
defined in the NPRM as a one-time report that is only required at the 
time of initial compliance with the AD.
    We agree. We have revised this AD to clearly state the reporting 
requirement is a one-time action submitted after the initial 
inspection.

Request To Update the P/N ``Costs of Compliance''

    James E. Dyer commented that there has been a revision to a P/N 
listed in the ``Costs of Compliance'' section of this AD, and we should 
change the P/N.
    We agree. We revised this AD to reflect the aileron hinge and 
rudder hinge P/N from 415-24003 to F24003 in the ``Costs of 
Compliance'' section.

Request To Limit the Aileron Free Play

    Vince Hammons and Jack Chmiel commented that the aileron free play 
should be limited to \1/8\ inch to \5/16\ inch, which they believe 
would be easily attainable and would remove any confusion on allowable 
amount of free play.
    We do not agree. Ercoupe Service Memorandums No. 56 and No. 57, 
both Revisions A, both dated September 1, 2008, state that \7/16\ inch 
is allowable for ailerons with counter weights, and \5/16\ inch is 
allowable for ailerons without counter weights per the original design. 
Anything less could be unattainable due to different wear patterns and 
usage between airplane units and the services times and duration of the 
type design for the fleet since inception.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the 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 (76 FR 20894, April 14, 2011) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 20894, April 14, 2011).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 2,600 airplanes of U.S. registry.
    We estimate the following costs to comply with 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, 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

[[Page 52208]]

that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have 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 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.
