Nitrogen Bottles:
There is no requirement for a one year visual internal inspection on the nitrogen bottles currently installed in the Westwinds. That was an old requirement for the Walter-Kidde bottles-- all of which have been replaced because they reached their life-limit.

Hydraulic Fuses
AD 98-06-10 requires the functional checking of the hydraulic fuses every three years or 1200 hours, which ever comes first. It means ALL THREE fuses, not just the indicator fuse. We are finding the sign-off for the AD just referencing the indicator fuse. Also, if you read the brake bleeding instructions in the manual, you will find that the fuse is required to be checked EACH time a brake is replaced and bled.

RVSM Re-certification Inspections
When the re-certifications come due for the FAR91.411 and 91.413. The shop accomplishing the re-certification has to follow the STC that was used for the original certification for RVSM. This information should be referenced in the original log entry.
