14 CFR Part 39

[Docket No. FAA-2012-1040; Directorate Identifier 2012-NM-029-AD]
RIN 2120-AA64


Airworthiness Directives; BAE Systems (Operations) Limited 
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 
BAE Systems (Operations) Limited Model BAe 146, and Avro 146-RJ series 
airplanes. This proposed AD was prompted by a report of loss of the end 
caps on the anti-icing piccolo tube of the wing leading edge. This 
proposed AD would require a detailed inspection of the end caps on the 
anti-icing piccolo tube for lost or loose end caps, and replacing or 
repairing the end caps if necessary. We are proposing this AD to detect 
and correct lost and loose end caps on the anti-icing piccolo tube, and 
ice accretion on the wing leading edge or run-back ice, which could 
lead to a reduction in the stall margin on approach and loss of 
controllability of the airplane.

DATES: We must receive comments on this proposed AD by November 19, 
2012.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0003, dated January 6, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    An operator reported the loss of the wing leading edge anti-
icing piccolo tube end caps on two aircraft. This was discovered 
during routine zonal inspections when the wing tips were removed. 
The loss of the end cap would result in a reduction in anti-icing 
efficiency, over the outboard portion of the leading edge of that 
wing, affecting approximately 25% of the wingspan towards the wing 
tip.
    The System Safety Analysis (SSA) classifies the loss of anti-
icing of both of the outer wings as hazardous if the loss is not 
indicated to the crew. The loss of a piccolo tube end cap would not 
be indicated to the flight crew and, therefore, this reduction in 
anti-icing capability on one wing must also be classified as 
hazardous.
    This condition, if not detected and corrected, could result in 
ice accretion on the wing leading edge, or run-back ice and could 
lead to a reduction in the stall margin on approach together with a 
reduction in roll control authority.
    For the reasons described above, this [EASA] AD requires a one-
off [detailed] inspection [for lost and loose end caps] of the 
piccolo tube end caps. The results of this inspection will be used 
to establish a suitable repeat inspection period, which will be 
introduced through the Maintenance Review Board (MRB) process.

    The corrective action is replacing or repairing the end caps if 
necessary. You may obtain further information by examining the MCAI in 
the AD docket.

Relevant Service Information

    BAE Systems (Operations) Limited has issued Inspection Service 
Bulletin ISB. 30-025, dated April 19, 2011. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI.

[[Page 60652]]

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.

Differences Between This AD and the MCAI or Service Information

    Although EASA Airworthiness Directive 2012-0003, dated January 6, 
2012, and BAE Systems (Operations) Limited Inspection Service Bulletin 
ISB. 30-025, dated April 19, 2011, specify a reporting requirement, 
this AD does not require reporting. This difference has been 
coordinated with EASA.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 2 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $340, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 8 work-hours and require parts costing $140, for a cost of 
$820 per product. 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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39
