C310 pilot experiences low manifold pressure at 11;000 ft and elects to shut down the engine and ret...

Narrative:

While in level cruise flight at 11;000 MSL I noticed a loss of manifold pressure in the right engine. As the engine was not developing normal power and considering the possibility of an exhaust leak; I shut the right engine down; declared an emergency; and returned to departure airport for landing. Descent; approach; landing and taxi-in were uneventful. Maintenance is inspecting the turbo charging system in order to diagnose the problem. Later that week I realized that the FAA would probably request a full report of the flight from me. I decided to go ahead and collect all the maintenance records pertaining to the right turbocharger by thoroughly reviewing the aircraft logbooks. In doing so; I noticed that the altimeter; pitot/static; and transponder checks required by 91.411 and 91.413 were out of date by 23 days. I mistakenly thought the previous checks had been done september 2009 (there is a logbook entry dated 9/2009 which I mistakenly thought was the IFR certifications but in reality was for another work order) and as such was planning to have them done in september of this year.lessons learned. The best way to prevent this is to keep a checklist in the aircraft showing the dates of required inspections and airworthiness directives. I have done so in the past but let that practice lapse. I will resume doing so in the future. Such a checklist will allow me to review time lines for required inspections prior to each flight in the future.
