The prebuy report

Here is the full pre-buy report from Paul McCracken... he flew from DFW to Indiana to inspect the plane, left at 4 am, spent the whole day pouring over the airplane, that night pouring over the logs, and the next day answering a million questions via phone and email...  Paul did a heck of a job and I highly recommend him to anyone considering buying a Beechcraft.

Logbook Research: AD’s, component history, maintenance history

AD’s of note:
2008-13-17: Circuit breaker replacement. Due by 08/2010.
2007-26-09: Hartzell propellers. Will be complied with at OH.

All logbooks are present. Comprehensive maintenance entries interspersed with minimal
inspections with little documented. Overall, average.

Mags: Have not been overhauled since new in 1989. LHE: both mags had the points replaced around 200 hrs ago. Left mag was replaced with a used serviceable mag recently.
RHE: original mags, no internal work documented.

Instrument Air pumps: RHE- 590 hrs TIS (1998) LHE- 550 hrs TIS (1999) 500-hr recommended replacement interval.

Alternators: one was replaced at 2322.2 Hobbs time. Other has 1310 hrs and 20 years since new.
Recommended inspection interval (coupling and bearings) 500-hrs.

2009: New cabin door seal.
2009: Starter adapter replaced. RHE. 2719.0 Hobbs.
2009: G600 and other major avionics upgrades.

Squawks, Discrepancies, Recommendations:

1. Props need overhaul soon. 20 years and 1310 hours is excessive. Airplane will be smoother after they are OH’d, guaranteed.
2. Old alternator is well past its recommended OH interval.
3. Left load meter reads 20% high. Repairs needed.
4. LH elevator needs to be stripped, etched, and repainted (and balanced) before corrosion eats through magnesium, mandating a reskin. May be too late. See: Frank Baker 530-893-5416, email address is Chico, CA
5. Instrument air regulator(s) need adjustment. Too high. Simple fix.
6. Check prop sync operation.
7. Magnetos need at least a 500-hr inspection, if not a complete OH. (1310 hours SNEW)
8. Monitor the low cylinders on the LHE for exhaust valve wear.
9. Both instrument pumps are overdue for their recommended replacement interval. (500-hr)
10. Heater PDT test is overdue. AD must be complied with.
11. Engine baffles should be completely re-worked with new rubber at next annual. Kits are available. DIY?
12. Strongly encourage you to get a modern engine monitor to utilize the GAMIjectors and operate your engines the right way.
13. Cloudy cabin door window can be replaced with a window that has a vent window in it by the mobile window guy, DBM Mods, Jim Klug, A master craftsman.
14. Get rid of the dual yoke after you get your check out. Your copilot/passenger will love the room the single affords. And flopping it over in flight is simple. You can make around $2k on it. Dual yokes on this vintage Baron & Bonanzas were meant for training only…they get in the way, otherwise.
