Airworthiness Directives; ASI Aviation Type Certificate Previously Held by Reims Aviation S.A. Airplanes Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is superseding Airworthiness Directive AD 201516
07 R1, which applied to certain Reims Aviation S.A. type certificate now held by ASI Aviation Model F406 airplanes.
AD 20151607 R1 required inspecting the left-hand and right-hand rudder control pedal torque tubes and replacing with a serviceable part as necessary.
Since the FAA issued AD 20151607
R1, the European Aviation Safety Agency EASA superseded its mandatory continuing airworthiness information MCAI to correct an unsafe condition on these products. This AD
retains the requirements of AD 2015
1607 R1, expands the applicability, and requires repeating the inspections using updated procedures. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective January 10, 2022.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of January 10, 2022.

SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20151607 R1, Amendment 3918328 80 FR 72563, November 20, 2015 AD 20151607
R1. AD 20151607 R1 applied to certain Reims Aviation S.A. type certificate now held by ASI Aviation Model F406 airplanes and required inspecting the left-hand and right-hand rudder control pedal torque tubes and replacing with a serviceable part as necessary. The NPRM published in the Federal Register on August 27, 2021 86
FR 48083.
The NPRM was prompted by AD
20190016, dated January 29, 2019
referred to after this as the MCAI, issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states:
An occurrence was reported where one pilot rudder control pedal of an F 406
aeroplane detached in flight. No change in aeroplane attitude occurred. The rudder was controlled using the co-pilot rudder pedals, and an uneventful landing was made.
Investigation results determined that the affected rudder pedal torque tube had failed due to a crack.
This condition, if not detected and corrected, could lead to further cases of rudder pedal torque tube failure, possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, ASI Aviation issued SB service bulletin F406104 to provide inspection instructions.
Consequently, EASA issued Emergency AD
20150159E later revised to require a onetime inspection of the rudder control pedal torque tubes, both left-hand LH and righthand RH, and, depending on findings, replacement with a serviceable part. That EASA AD also required inspection of replacement rudder control pedal torque tubes before installation.
Since EASA AD 20150159R1 was issued, further occurrences were reported of finding cracks on rudder pedal torque tubes.
Consequently, ASI Aviation issued the SB as
PO 00000

Frm 00023

Fmt 4700

Sfmt 4700

68897

defined in this EASA AD to provide instructions for repetitive visual, dyeor fluorescent-penetrant, and magnetic particle inspections.
For the reason described above, this EASA AD retains the requirements of EASA
AD 20150159R1, which is superseded, and requires implementation of repetitive inspections of the affected parts and, depending on findings, replacement.

0712.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAAs 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 determined that air safety requires adopting this AD
as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed ASI Aviation Service Bulletin No. F406104, Revision 1, dated December 14, 2018. The service information specifies procedures for repetitively inspecting the left-hand and right-hand rudder control pedal torque tubes for cracks and replacing with a serviceable part. 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 ADDRESSES.
Differences Between This AD and the MCAI
The MCAI specifies an initial compliance time of during the next 600
flight hour FH maintenance check for a visual and a dye or fluorescent penetrant inspection. This AD requires those initial inspections before further flight.
The MCAI specifies an initial compliance time of during the next 2,400 FH maintenance check for a magnetic particle inspection. This AD
requires that initial inspection within
