Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 32 months from the effective date of this AD: Do a detailed visual inspection for missing fasteners and damage, including cracking, in the fuselage skin attached to stringer 19 between fuselage station (FS) FS945.75 and FS961.45. If any damage or missing fasteners are found: Before further flight, repair any damage found, and install fasteners where missing, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-53-7547, dated July 21, 2021.
Unsafe condition
This AD was prompted by a report that certain fasteners attaching the fuselage skin to a certain stringer may be missing. The FAA is issuing this AD to address missing fasteners, which may subject the skin to inter-rivet buckling under compressive load. The unsafe condition, if not addressed, could create a hazard of permanent deformation and/or cracking of the skin.
Affected ADs
None.
