Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2015-07-05, which applies to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. AD 2015-07-05 requires repetitive external eddy current inspections on the aft skin lap joints of the rear fuselage for cracking, corrosion, and other defects, and repair if necessary. Since the FAA issued AD 2015- 07-05, an inspection has been added and certain compliance times must be revised to address the unsafe condition. This proposed AD would continue to require the actions in AD 2015-07-05, at certain revised compliance times, and also require repetitive low frequency eddy current (LFEC) inspections for any cracking, corrosion, and other defects in the aft skin lap joints of the rear fuselage and in the fuselage skin panels, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.

Discussion
The FAA issued AD 2015-07-05, Amendment 39-18133 (80 FR 19871,
April 14, 2015) (AD 2015-07-05), for all BAE Systems (Operations)
Limited Model BAe 146 series airplanes and Model Avro 146-RJ series
airplanes. AD 2015-07-05 requires repetitive external eddy current
inspections on the aft skin lap joints of the rear fuselage for
cracking, corrosion, and other defects, and repair if necessary. AD
2015-07-05 resulted from a report of a pressurization problem on an
airplane during climb-out; a subsequent investigation showed a crack in
the fuselage skin. The FAA issued AD 2015-07-05 to address cracking,
corrosion, and other defects, which could affect the structural
integrity of the airplane.
Actions Since AD 2015-07-05 Was Issued
Since the FAA issued AD 2015-07-05, it has been determined that
adding repetitive LFEC inspections for any cracking, corrosion, and
other defects in the aft skin lap joints of the rear fuselage and in
the fuselage skin panels are necessary. The compliance times for
inspection of certain stringers must also be revised.
The Civil Aviation Authority (CAA), which is the aviation authority
for the United Kingdom, has issued CAA AD G-2021-0008, dated September
8, 2021 (also referred to after this as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all BAE Systems (Operations) Limited Model BAe 146 series airplanes
and Model Avro 146-RJ series airplanes. You may examine the MCAI in the
AD docket on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching
for and locating Docket No. FAA-2022-0508.
This proposed AD was prompted by a report of a pressurization
problem on an airplane during climb-out; a subsequent investigation
showed a crack in the fuselage skin; and that repetitive LFEC
inspections in the rear fuselage aft skin lap joints and in the
fuselage skin panels are necessary. Certain compliance times also must
be revised. The FAA is proposing this AD to address cracking,
corrosion, and other defects on the rear fuselage aft skin joints and
frames and in the fuselage panels, which could affect the structural
integrity of the airplane. See the MCAI for additional background
information.
Related Service Information Under 1 CFR Part 51
BAE Systems (Operations) Limited has issued Inspection Service
Bulletin 53-239, including Appendix 2, Revision 5, and including
Appendix 3, Revision 1, dated March 2, 2017. This service information
describes procedures for repetitive external eddy current and LFEC
inspections on the aft skin lap
[[Page 27039]]
joints of the rear fuselage and in the fuselage skin panels, for any
cracking, corrosion, and other defects (e.g., surface damage and spot
displacement); and repair if necessary.
This proposed AD would also require BAE Systems (Operations)
Limited Inspection Service Bulletin 53-239, including Appendix 2,
Revision 3, dated May 7, 2014, which the Director of the Federal
Register approved for incorporation by reference as of May 19, 2015 (80
FR 19871, April 14, 2015).
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
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would retain all of the requirements of AD 2015-
07-05, with certain revised compliance times. This proposed AD would
also require accomplishing the actions specified in the service
information described previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 20 airplanes of
U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 8 work-hours x $85 $0 $680 per inspection $13,600 per
2015[dash]07[dash]05. per hour = $680 cycle. inspection cycle.
per inspection
cycle.
New proposed actions............. 5 work-hours x $85 0 $425............... $8,500 per
per hour = $425. inspection cycle.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the repairs specified in this proposed 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.
The FAA is 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
The FAA has 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) Will not affect intrastate aviation in Alaska, and
(3) 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.
List of Subjects in 14 CFR Part 39
