Required Actions
Within 50 hours time-in-service (TIS), create a component history card or equivalent record for each crosstube and begin counting and recording the number of accumulated landings. Install CAUTION decals on the pilot and co-pilot sides of each helicopter. Confirm the crosstube is within horizontal deflection limits and replace it if not. Perform a recurring fluorescent penetrant inspection (FPI) of each crosstube and upper center support for cracks, corrosion, nicks, scratches, dents, or other damage. Repair damaged components within acceptable limits, rework crosstubes by bonding abrasion strips, and replace unairworthy crosstubes.
