First, because of frequent reports of landing gear collapses, many resulting from rod end failure, the ABS tehcnical staff recommends following manufacturer's guidance on landing gear parts inspection, overhaul and replacement.
The key to your question is that Chapter Five of the Hawker Beechcraft maintenance manuals are not labeled "airframe limitations". Here is the precise wording from the Maintenance Manual:
Time Limits/Maintenance Checks
1. Airworthiness Limitations Statement - Inspection/Check
There are no additional Airworthiness Limitations as defined in 14CFR 23, Appendix G, G23.4 for the Bonanza airplanes. The Airworthiness Limitations section is FAA approved and specifies maintenance required under Section 43.16 and Section 91.403 of the Federal Aviation Regulations unless an alternative program has been FAA Approved.
There is a similar note in the Manuals for other ABS-type airplanes. Consequently, the time limits and maintenance checks of the Beech maintenance manuals are recommendations, but not airworthiness limitations.
That said, I know from first-hand sources that the Beech manuals are currently being revised to make at least some of the now-recommended time limits into airworthiness limitations. It is entirely within the manufacturer's authority to do this under Federal regulations. ABS continues to be in touch with the FAA and Hawker Beechcraft about this, and will provide updates as news occurs.
