We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This AD was prompted by a report of the failure, due to overheat, of a bracket on which the earth post (EP) for the generator and propeller de-ice systems is located. This AD requires an inspection of the affected EPs and attachment structure for damage, an inspection of the earth cables of the generator and propeller de-ice system for signs of overheating and arcing damage, a torque check of the affected EP stiff nuts, an electrical high current bonding check of the bracket, and corrective actions if necessary. We are issuing this AD to detect and correct an overheat failure of the EPs for the generator and propeller de-ice system, and possible degradation of the wing front spar cap and/or web, which could affect the structural integrity of the wing.

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 BAE Systems 
(Operations) Limited Model 4101 airplanes. The NPRM published in the 
Federal Register on September 3, 2014 (79 FR 52270). The NPRM was 
prompted by a report of the failure, due to overheat, of a bracket on 
which the EP for the generator and propeller de-ice systems is located. 
The NPRM proposed to require an inspection of the affected EPs and 
attachment structure for damage, an inspection of the earth cables of 
the generator and propeller de-ice system for signs of overheating and 
arcing damage, a torque check of the affected EP stiff nuts, an 
electrical high current bonding check of the bracket, and corrective 
actions if necessary. We are issuing this AD to detect and correct an 
overheat failure of the EPs for the generator and propeller de-ice 
system, and possible degradation of the wing front spar cap and/or web, 
which could affect the structural integrity of the wing.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0006, dated January 7, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition. The MCAI states:

    An occurrence was reported involving a Jetstream 4100 aeroplane, 
where a bracket, on which the earth post for the generator and 
propeller de-ice systems is located, failed due to overheat. 
Although the earth post and cables were not damaged, the mounting 
bracket and underlying structure were damaged to the extent that 
repair of the wing front spar web was necessary. Furthermore, the 
aft engine cross support rod, which is attached to the same bracket, 
was found damaged, as a result of excessive current

[[Page 16556]]

load, and required replacement. The subsequent investigation 
determined that, due to the damage tolerance of the aft engine cross 
rod support, the rod does not present an airworthiness issue. 
However, as a consequence of overheat failure of the earth post, 
degradation of the wing front spar cap and/or web could affect the 
structural integrity of the wing.
    This condition, if not detected and corrected, could reduce the 
capacity of the wing to support loads, possibly resulting in wing 
structure failure and consequent loss of the aeroplane.
    To address this potential unsafe condition, BAE Systems 
(Operations) Ltd issued [Inspection] Service Bulletin (SB) J41-24-
043 [Revision 2, dated August 21, 2013] to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time visual inspection of the affected earth posts, an electrical 
high current bonding check of the bracket and, if discrepancies are 
detected, accomplishment of applicable corrective action(s).

The required actions include a general visual inspection of the 
affected EPs and attachment structure for damage; a general visual 
inspection of the earth cables of the generator and propeller de-ice 
system for arcing damage and signs of overheating of the cable 
insulation and terminal tags; a torque check of the EP2 and EP4 stiff 
nuts; an electrical high current bonding check of the bracket; and 
corrective actions if necessary. Corrective actions include repair of 
damaged structure, replacement of damaged cables, cleaning of all 
applicable surfaces to achieve the necessary resistance value, and 
correction of the torque load of EP stiff nuts.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0619-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 52270, September 3, 
2014) or on the determination of the cost to the public.

Changes Made to This AD

    BAE Systems (Operations) Limited has issued Inspection Service 
Bulletin J41-24-043, Revision 3, dated June 16, 2014. This service 
bulletin states that ``this revision does not require rework of the 
modification(s) embodied by earlier revision of this service 
bulletin.'' We have revised paragraphs (g) through (k) of this AD to 
reference this service information. We have revised paragraph (l) of 
this AD to give credit for actions done prior to the effective date of 
this AD using BAE Systems (Operations) Limited Inspection Service 
Bulletin J41-24-043, Revision 2, dated August 21, 2013.

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 52270, September 3, 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 52270, September 3, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed BAE Systems (Operations) Limited Service Bulletin J41-
24-043, Revision 3, dated June 16, 2014. The service information 
describes procedures for an inspection of the earth post EP2 (left) and 
earth post EP4 (right) on the structure for the left and right power 
plants. This service information is reasonably available; see ADDRESSES 
for ways to access this service information.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this proposed AD on U.S. operators to be $1,360, or $340 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, 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.
