SUPPLEMENTARY INFORMATION:
Background The Federal Office of Civil Aviation FOCA, which is the aviation authority for Switzerland, has issued FOCA AD
HB2021001E, dated January 8, 2021
referred to after this as the MCAI, to address the unsafe condition on Pilatus Model PC7 airplanes. The MCAI states:
An occurrence was reported where in an in service event a missing release bar retaining screw on a Harley-type buckle assembly installed on a harness shoulder strap on an ejection seat was detected.
This condition, if not corrected, could lead to loss of pilot restraint and consequently loss of aeroplane control or injuries to the crew.
To address this potential unsafe condition, Pilatus and IrvinGQ issued the service bulletins SBs to provide inspection instructions.
For the reason described above, this FOCA AD requires the inspection of the Harley-type buckle assemblies on the seat harnesses of the front and rear seats, as defined in this AD, and prohibits re-
installation of affected parts.

FOCA advises that the release bar retaining screws on the affected Harleytype buckle assemblies were incorrectly peened during manufacture. This inadequate peening of the retaining screws has led to loose screws that can potentially be removed by hand or the actual screw falling out of the assemblies. You may examine the MCAI
in the AD docket at https
www.regulations.gov by searching for and locating Docket No. FAA2021
0049.
FAAs Determination This product has been approved by the aviation authority of another country and is approved for operation in the United States.
