Airworthiness Directives; ASI Aviation (Type Certificate 
Previously Held by Reims Aviation S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all ASI Aviation (type certificate previously held by Reims 
Aviation S.A.) Model F406 airplanes. This proposed AD was prompted by 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as failure of a circuit breaker (CB) switch. This proposed AD 
would require replacing certain CB switches and establishing a life 
limit for the CB switches. The FAA is proposing this AD to address the 
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by October 12, 
2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2019-0015, dated January 29, 2019 (referred to after this as ``the 
MCAI''), to address an unsafe condition on ASI Aviation (type 
certificate previously held by Reims Aviation S.A.) Model F406 
airplanes. The MCAI states:

    After the Federal Aviation Administration issued AD 2005-20-25, 
applicable to Cessna 400 series aeroplanes equipped with certain 
avionics bus CB switches, it was determined that, due to design 
commonality, one of the affected avionics bus CB switches, P/N [part 
number] CM3589-50, was also installed on Reims F 406 aeroplanes.
    This condition, if not corrected, could lead to smoke and/or 
burning smell in the cockpit, possibly resulting in reduced control 
of the aeroplane.
    To address that potential unsafe condition, RAI issued SB 
[service bulletin] F406-62 to provide instructions to remove certain 
switches from service. Consequently, EASA issued AD 2006-0134 to 
require identification of the date code of P/N CM3589-50 CB switches 
and, depending on findings, replacement with improved design CB 
switches, P/N 4061-2400-1. That [EASA] AD also imposed a life limit 
on the affected CB switches P/N CM3589-50.
    Since that [EASA] AD was issued, in-service occurrences of smoke 
and burning smell in the cockpit have been reported on F 406 
aeroplanes. Technical investigations revealed that these were due to 
failure of CB switches P/N CM3589-20, which are used to control the 
propeller de-icing circuit. Prompted by these events, ASI Aviation 
issued the applicable SB (as defined in this [EASA] AD) to provide 
instructions to replace the affected parts with serviceable parts.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2006-0134, which is superseded, expands the 
range of affected parts, and requires replacement of P/N CM3589-20 
CB switches with improved design CB switches P/N 406E2450-00000-100. 
This [EASA] AD also replaces the previous life limit, 1 000 flight 
hours (FH) for certain P/N CM3589-50 CB switches, with a 6 year 
calendar time life limit, and also imposes that limit on the 
improved design CB switches.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0714.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed ASI Aviation Service Bulletin No. F406-62, 
Revision 01, dated December 14, 2018, which specifies inspecting the CB 
switches to determine the date code, replacing CB switches with certain 
date codes, and establishing a life limit of 6 years for the new CB 
switches. The FAA also reviewed ASI Aviation Service Bulletin No. F406-
90, dated December 14, 2018, which specifies replacing the CB switches 
and establishing a life limit of 6 years for the new CB switches. 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 this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is issuing this NPRM 
after determining the unsafe condition described previously is likely 
to exist or develop on other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information already described, except as discussed under 
``Differences Between this Proposed AD and the MCAI.''

Differences Between This Proposed AD and the MCAI

    The MCAI allows installation of an affected CB switch until the 
airplane is modified. This proposed AD would prohibit installation of 
an affected CB switch as of the effective date of this AD.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 4 airplanes of U.S. registry.
    The FAA also estimates that it would take about 5 work-hours per 
airplane to comply with the inspection required by this proposed AD. 
The average labor rate is $85 per work-hour.
    Based on these figures, the FAA estimates the inspection cost of 
this proposed AD on U.S. operators to be $1,700 or $425 per airplane.
    In addition, the FAA estimates that each replacement required by 
this proposed AD would take about 1 work-hour and require parts costing 
$350. Based on these figures, the FAA estimates the replacement cost of 
this proposed AD on U.S. operators to be $435 per airplane.

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

[[Page 48069]]

develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
