Airworthiness Directives; Viking Air Limited Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Viking 
Air Limited Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III 
airplanes. This AD results from mandatory continuing airworthiness 
information (MCAI) issued by an aviation authority of another country 
to identify and

[[Page 64054]]

correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as corrosion of the elevator control rod and of 
the elevator actuating lever on the control column. We are issuing this 
AD to detect and correct corrosion and/or cracking of the elevator 
control rod assemblies and the elevator actuating lever, which if not 
detected and corrected, could cause these components to fail. This 
failure could result in loss of control.

DATES: This AD is effective October 24, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of October 24, 
2016.

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 all Viking Air Limited 
Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes. The NPRM 
was published in the Federal Register on March 3, 2016 (81 FR 11132). 
The NPRM proposed to correct an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. The MCAI states:

    There have been a number of reports of corrosion and/or cracking 
at the elevator actuating lever on the control column, in the 
elevator control rod assemblies, and at the rod end plug.
    Undetected corrosion and/or cracking of the elevator control rod 
assemblies or elevator actuating lever may lead to the failure of 
the components with consequent loss of aeroplane control.

The MCAI requires visually inspecting the elevator control rod 
assemblies, the elevator actuating lever on the control column, and the 
control column torque tube for corrosion, cracking, and/or other 
damages, and repairing or replacing damaged parts. The MCAI also 
requires incorporating revisions into the maintenance program and adds 
a life limit to certain elevator control rod assemblies. The MCAI can 
be found in the AD docket on the Internet at https://www.regulations.gov/document?D=FAA-2016-4229-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (81 
FR 11132, March 3, 2016) and the FAA's response to each comment.

Request To Change Inspection Procedure for the Elevator Control Rod

    Roger Braun requested allowance for inspecting the elevator control 
rod without removing it from the airplane.
    The commenter stated that even though the inspection procedure in 
Viking Air Limited DHC-2 Beaver Service Bulletin Number: V2/0005, 
Revision `C', dated July 17, 2015 (SB No. V2/0005, Rev. C), requires 
removing the elevator control rod, that doing so is excessively 
invasive and adds an increased risk of maintenance errors and/or damage 
to the part over simply inspecting it in place.
    We do not agree with the commenter. The elevator control rod ends 
are not required to be removed from its assembly. Removal of the 
elevator control rod assembly is necessary to do the required 
inspections. Viking Air Limited and Transport Canada determined that 
removing the elevator control rod assembly is necessary to adequately 
do the inspection, and the process of removing the elevator control rod 
assembly does not pose additional risk to safety.
    We have not changed the AD based on this comment.

Request To Rename/Revise the Airworthiness Limitations Section

    Roger Braun requested to omit the requirement to revise the 
Airworthiness Limitation section and instead include the repetitive 
inspection in the final rule AD action. The commenter stated that it is 
very hard to find the compliance times for the repetitive inspections, 
which are embedded in the temporary revisions to be inserted into the 
Airworthiness Limitation section of the FAA-approved maintenance 
program. The commenter asked that instead of inserting continued 
airworthiness instructions into the manual, why not include the 
language ``repeat inspection every 400 flight hours'' in the AD 
actions?
    We partially agree. We agree that the repetitive inspection 
requirements that are embedded in the temporary revisions are not clear 
or easy to understand. However, we disagree with writing the repetitive 
inspections into the AD because Viking Air Limited plans to have all 
the required inspections in their maintenance manual rather than 
dispersed over numerous other documents. We have determined that 
revising the Airworthiness Limitations section of the FAA-approved 
maintenance program to mandate the repetitive inspections is 
acceptable. To clarify the intent of the of the Airworthiness 
Limitations section, we have changed the heading of that section to 
Repetitive Inspection in order to make the repetitive inspections 
clear.
    We have changed the AD based on this comment.

Request To Allow Minor Surface Corrosion

    Roger Braun requested that the final rule AD action be changed to 
include an allowance for minor surface corrosion.
    The commenter stated that the proposed AD and the related service 
information are vague in delineating what corrosion is considered 
unacceptable by stating if ``any corrosion'' is found, which would be 
an unrealistic standard. The commenter requested relief for minor 
surface corrosion.
    We do not agree. Viking Air Limited and Transport Canada determined 
that all corrosion is unacceptable. Small surface corrosion must also 
be repaired following the SB No. V2/0005, Rev. C, dated July 17, 2015.
    We have not changed the AD based on this comment.

[[Page 64055]]

Request for Clarification of Life Limit for Part Number (P/N) C2FC619A-
11

    Roger Braun requested clarification in the final rule AD action to 
clearly state that P/N C2FC619A-11 elevator control rod is not a life-
limited part.
    The commenter stated that it is not entirely clear in the proposed 
AD that elevator control rod, P/N C2FC619A-11, is not a life-limited 
part. The commenter requested further clarification in the final rule 
AD action specifying that there is no life limit on P/N C2FC619A-11.
    We agree with the commenter and have added a statement in the AD to 
further clarify that the P/N C2CF619A-11 elevator control rod has no 
life limit.
    We have changed the AD based on this comment.

Request To Extend Repetitive Inspection Compliance Times

    Roger Braun requested relief for the repetitive inspection of the 
elevator control rods with a known date of manufacture, for example, 5 
or 10 years.
    We infer that the commenter wants the repetitive inspections 
changed from every 400 hours time-in-service (which is what is 
specified in the Temporary Revisions to the Airworthiness Limitations 
section) to a repetitive 5-year inspection.
    We do not agree. Viking Air Limited and Transport Canada determined 
that damage can occur at any time. Therefore, no threshold is provided 
that will allow a certain period of time before the start of the 
repetitive inspection requirement.
    We have not changed the AD based on this comment.

Request To Change Repetitive Inspection Compliance Time

    Mark Henshaw requested the repetitive inspections be yearly/12-
month inspections. The commenter stated that he operated his airplane 
400-500 hours per summer season, as most operators do. The commenter 
stated that the 400-hour recurring inspection will require the 
operators to remove the airplane from service, remove the pilot floor 
panel, pilot side panels, oil cooler cowl, side after cowl, unbolt the 
control column bearings and the inboard control column mount then 
remove it, pull the elevator control rod out of the airplane, and then 
do the elevator control rod inspection. We infer that the commenter is 
making the point that the inspection is very labor intensive. The 
commenter stated that this inspection would fit nicely into a yearly/
12-month inspection criteria instead of what probably will fall right 
in the middle of their busy season when a 100-hour inspection may or 
may not have been scheduled. This inspection will add at least 4-6 
hours (on a good night) to a routine 100-hour inspection.
    The commenter requested an alternative of yearly/every 12 months, 
that way all the elevator control rods get looked at every year and 
nobody has to stop their airplane right in the middle of their busy 
season for this inspection.
    The commenter stated that there has never been a requirement to 
remove the elevator control rod, and does agree that doing the 
inspection is great idea, but not every 400 hours.
    We do not agree that yearly/12 month inspections are an acceptable 
level of safety to address the unsafe condition. The 400-hour 
inspection should assure that any damage will be detected before it 
rises to an unsafe level. Additionally, Viking Air Limited informed us 
that there are existing inspections specified in the applicable 
maintenance manuals around the same affected area as this AD that 
requires lifting of floor boards.
    We have not changed the AD based on this comment.

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:
     [Agr]re consistent with the intent that was proposed in 
the NPRM (81 FR 11132, March 3, 2016) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (81 FR 11132, March 3, 2016).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Viking Air Limited DHC-2 Beaver Service Bulletin 
Number: V2/0005, Revision `C', dated July 17, 2015; Temporary Revision 
No.: 2-38, dated March 4, 2015, of VIKING PSM NO.: 1-2-2, AIRCRAFT: 
DHC-2 BEAVER, SERIES: ALL, PUBLICATION: MAINTENANCE MANUAL; and 
Temporary Revision No.: 2T-14, dated March 4, 2015, of VIKING PSM NO.: 
1-2T-2, AIRCRAFT: DHC-2 TURBO BEAVER, SERIES: ALL, PUBLICATION: 
MAINTENANCE MANUAL. The service information describes procedures for 
doing detailed visual inspections of the elevator control rod 
assemblies, the elevator actuating lever on the control column, and the 
control column torque tube for corrosion, cracking, and/or other 
damages. The service bulletin also describes procedures for repairing 
or replacing damaged parts. 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 the AD.

Costs of Compliance

    We estimate that this AD will affect 135 products of U.S. registry. 
We also estimate that it will take about 11.5 work-hours per product to 
comply with the basic inspection requirements of this AD. The average 
labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the basic 
inspection requirements of this AD on U.S. operators to be $131,962.50, 
or $977.50 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 8 work-hours and require parts costing $1,859, for a cost of 
$2,539 per product. Contact Viking Air Limited at the address 
identified in the ADDRESSES section of this AD for current pricing and 
lead time. 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 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

[[Page 64056]]

responsibilities among the various levels of government.
    For the reasons discussed above, I certify 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.
