Background
SUMMARY:

DATES:

67307

The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to all ASI Aviation type certificate previously held by Reims Aviation S.A. Model F406 airplanes.
The NPRM published in the Federal Register on August 27, 2021 86 FR
48067. The NPRM was prompted by MCAI originated by the European Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Union. EASA
issued AD 20190015, dated January 29, 2019 referred to after this as the MCAI, to correct 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 20052025 70 FR 59237, October 12, 2005, 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 CM358950, 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 F40662 to provide instructions to remove certain switches from service. Consequently, EASA
issued AD 20060134 to require identification of the date code of P/N
CM358950 CB switches and, depending on findings, replacement with improved design CB switches, P/N 406124001. That EASA
AD also imposed a life limit on the affected CB switches P/N CM358950.
